Peter Van Den Heede, Head of Sales and Marketing, Benelux, ABB Motion, explains how electrification systems are paving the way for sustainable urban landscapes.  As the fight against climate change intensifies, the European Union has set crystal clear targets on the path to Net Zero. If we are to meet the EU’s ambitious goals of a 55 percent reduction in greenhouse gas emissions by 2030, and complete climate neutrality by 2050, then we need to find ever-smarter ways to save energy.  District heating and cooling (DHC) systems, powered by low-carbon options like, biomass, geothermal energy, and waste heat, have long been recognized as a sustainable solution. However, the real breakthrough in decarbonizing urban heating emerges when district heating integrates with electrification. Indeed, the integration of DHC systems with electricity networks is emerging as a crucial step toward sustainable heating and cooling in urban areas worldwide. Key Technologies For Sustainable Heating Advanced technologies, including large-scale compressors, ultra-low harmonic drive solutions, and optimization software like ABB’s OPTIMAX™, play a pivotal role in managing energy flows and ensuring a balance between supply and demand. There has also been a significant shift toward combined heat and power (CHP) schemes, which are exemplary for their energy efficiency and contribution to grid stability. This article explores in detail the combined potential of electrification and DHCs to deliver significant energy savings, and the key technologies paving the way to sustainable urban heating. The challenges and opportunities of integrating renewables Traditionally, of course, oil and gas were also considered to be a relatively low-cost source of energy In the pursuit of sustainable urban heating, electrification refers to the process of expanding the use of electricity in a manner that prioritizes the planet. This includes the increasing integration of renewable energy sources, rather than traditional fossil fuels, to minimize the environmental impact. Historic resistance to renewable energy for DHCs has largely been driven by an entrenched reliance on fossil fuels and their established, familiar infrastructure. Traditionally, of course, oil and gas were also considered to be a relatively low-cost source of energy. But with rising oil prices making alternative electricity generation more appealing, the landscape is shifting. This shift is particularly significant for heating systems with an electrical component, as they can leverage diverse energy sources, including renewables, which reduces their vulnerability to fluctuations in the price of oil.  And while fossil fuel technologies have long been perceived as more reliable and capable of providing consistent heat compared to renewable sources such as wind and solar – both of which are inherently intermittent – new technologies are unlocking the powerful synergies between DHCs and electrification to improve electrical grid power quality and efficiency, further supporting the case for renewable energy sources. The merits of combined heat and power schemes Combined heat and power (CHP) schemes have gained popularity across Europe as a sustainable heating and cooling solution, primarily due to their enhanced energy efficiency. CHP systems are designed to generate both electricity and useful heat simultaneously from a single energy source, such as natural gas, biomass, or waste heat. This dual production of energy significantly improves overall efficiency compared to separate electricity and heat generation methods, reducing the environmental impact and resource consumption. CHP systems are designed to induce electricity and useful heat simultaneously from a single source Utilizing waste heat that would otherwise be discarded, such as in space or water heating, can help reduce the demand for conventional heating fuels. CHPs maximize the use of available energy, lowering greenhouse gas emissions and increasing sustainability in district heating systems. Additionally, CHPs can be integrated with a variety of renewable energy sources and can contribute significantly to grid stability by switching swiftly between alternative heat sources. But opportunities can also be found right under our feet. Such was the case in Denmark, where an underground water source proved pivotal in supplying carbon-neutral heating to an entire town. Transforming district heating in Broager, Denmark The district heating and cooling facility in Broager faced the challenge of achieving carbon neutrality while efficiently meeting the energy needs of its community of approximately 1,200 people. With the increasing global emphasis on sustainability, there was a need to transition from conventional heating methods to more eco-friendly alternatives. Broager District Heating (BDH) pioneered a sustainable solution by implementing a comprehensive district heating system. The key components of this solution included harnessing solar and geothermal energy and utilizing the local groundwater as a heat source. BDH adopted pioneering edge technologies, such as a first-of-its-kind groundwater heat pump system, a vast solar thermal collector system, and an electrical boiler for heating the cool groundwater. ABB components, including advanced variable speed drives (VSDs) and motors, are playing a crucial role in optimizing the system's performance. Integration of ABB components The intuitive and user-friendly nature of ABB drives facilitated seamless operation and maintenance The geothermal heat pump, a standout feature of the system, extracted thermal energy from underground water, achieving an impressive Coefficient of Performance (COP) of 4, meaning it produced 4 kW of heat for every 1 kW of electricity input. ABB’s drives were employed to regulate motor speeds in the compressors, ensuring energy efficiency and enabling significant energy savings, of up to 60 percent. The intuitive and user-friendly nature of ABB drives facilitated seamless operation and maintenance. Broager District Heating's commitment to sustainable practices resulted in a district heating facility that is almost 100 percent carbon neutral. The integration of ABB components, particularly variable speed drives (VSDs) to regulate compressor motors, contributed to remarkable energy savings and efficiency improvements. VSDs and high-efficiency motors offer next-level power savings Motors used in district energy systems usually run constantly at full speed. To adjust the airflow of a fan or the flow from a pump, operators generally use mechanical methods such as throttling, which is inefficient and energy-wasting. However, adopting VSDs can significantly reduce energy consumption in heat generation since they will adjust the motors’ speed to suit an application’s exact requirements. Depending on the application, VSDs can generally produce energy savings of 20 to 60 percent. Depending on the application, VSDs can generally produce energy savings of 20 to 60 percent Network operators can further reduce energy consumption in heat generation, transmission, and distribution by pairing VSDs with the latest IE4 or IE5 efficiency class motors, instantly reducing a facility’s carbon footprint. In the context of today’s escalating energy costs, return on investment is often realized within a year or less. Ultra-low harmonic (ULH) drives present a further opportunity to improve energy efficiency, by minimizing electrical disturbances and reducing power losses, ensuring a smoother and more efficient conversion of electrical energy into mechanical power. Digitalization for improved reliability District energy systems must demonstrate a consistently high degree of reliability and efficiency. Facility managers are increasingly digitalizing processes with smart sensors and connectivity devices to improve performance. The most advanced drive systems can even automatically detect blockages in air systems, gears needing lubrication, and heat pumps facing bearing failures. Sensors placed throughout the entire DHC system enable proactive maintenance by allowing operators to spot possible issues before they present major problems that could result in unscheduled downtime. ABB’s OPTIMAX™ software platform Ability to monitor and optimize the district heating system in an integrated way across all power streams  The ability to monitor and optimize the district heating system in an integrated manner across all energy streams is where the synergy with the electrical grid really shines, like with ABB’s OPTIMAX™ software platform. It not only ensures that the total carbon emissions and energy costs are significantly reduced, but also that the resilience of both the heating and electrical grid is improved due to the addition of a forecasting and optimal planning step.  This is especially valuable in highly congested areas, where normal operations would more quickly reach their technical limits, pioneering to serious, unplanned downtime. Luckily, these software applications have seen multiple decades of development time and are robust and proven technologies. The future landscape Improving energy efficiency is not a choice. It’s a necessity if we are to combat climate change. Here, the dynamic synergy between DHC systems and electrification emerges as a vital step, creating powerful sustainability opportunities and standing as a pivotal cornerstone in our quest for carbon neutrality. Recent and planned energy projects across Europe underscore the importance of these synergies. For example, in Belgium, the Antwerp 2030 roadmap is utilizing a citywide heat network to annually reduce CO2 emissions by 71,000 tons by 2030. While in Denmark, Aalborg’s ambitious plan for a 176 MW heat pump exemplifies the potential of such pumps in creating a more sustainable urban heating ecosystem. Furthermore, localized heat islands in areas like Kiel, Germany present a tangible vision of the future of DHC based on sustainable heat sources. The smart and powerful mix of high-efficiency components, optimization software, and integrated heat and electric synergies is a winning combination that will undoubtedly accelerate our journey toward a greener future.

Nothing is immune to entropy. As buildings age, they suffer natural breakdowns in efficiency, performance, and useability, compromising occupant comfort and leading to higher energy bills. Luckily, they do not have to stay that way. Retro-commissioning brings existing structures up to speed so they can function their best.  What Is Commissioning?  Commissioning helps buildings operate as the owners intended and ensures staff maintains their equipment and systems. During new construction, commissioning teams may conduct a quality assurance process on a structure to ensure it will perform properly. For example, making HVAC equipment more energy-efficient often requires advanced control strategies. It is ideal to implement these controls early in the construction process.  Recommissioning Recommissioning occurs when a facility experiences a more commissioning process Recommissioning occurs when a building undergoes an additional commissioning process. A change in ownership or building use may trigger the decision to recommission a structure. Operational problems or poor energy performance can also lead owners to recommission their properties.  Since the building has already been commissioned in the past, the commissioning team may have initially included a plan for future renovations. Following it simplifies the recommissioning process.  Retro-Commissioning An existing building that has never been commissioned may be retro-commissioned to modernize it, improve occupant comfort and boost energy efficiency. It is common to retro-commission during a planned renovation or upgrade to the structure.  Retro-commissioning ensures a building’s new features meet the owner’s and occupants’ needs, as well as government regulations. It can resolve problems that occurred during the design and construction phase and address new issues that arose as the structure aged.  The Importance of Retro-Commissioning One of the most obvious benefits of retro-commissioning a building is the cost savings One of the most obvious benefits of retro-commissioning a building is the cost savings. According to the Environmental Protection Agency (EPA), the average retro-commissioning project leads to a 15% reduction in energy consumption and saves building owners 27 cents per square foot. Many utility companies also offer performance-based incentives to owners based on how many kilowatt-hours their retro-commissioning project saves. Additionally, retro-commissioning can reduce maintenance costs in the long run and extend equipment life. Improving a building’s heating, cooling, and humidity control can increase tenant comfort and retention. Building sector Retro-commissioning often boosts air quality by ensuring adequate air intake, improving HVAC filtration and reducing moisture. It may even increase a structure’s property value.  The building sector—including construction, heating, lighting, and cooling for companies and homes—accounts for over 33% of worldwide energy consumption and emissions. Retro-commissioning makes structures more sustainable and helps companies comply with environmental laws, an increasingly important factor in modern business operations.  Which Parts of a Building Can Be Retro-Commissioned? Retro-commissioning addresses many complex systems within a building, including: HVAC: A commissioning authority or facilities team can retro-commission a structure’s HVAC system, including inspecting air economizers and demand-controlled ventilation for proper function. They can also check for blocked air registers, broken exhaust fans and whether the HVAC equipment complies with building occupancy codes. This process may reveal broken machinery or inefficiencies that waste energy, reduce occupant comfort and harm indoor air quality.  Lighting and Lighting Controls: Old lightbulbs are often inefficient and require more frequent maintenance than newer types like LEDs. Retro-commissioning teams can look at a building’s lighting to determine if the building would benefit from different kinds of lights. Additionally, they can install smart lighting systems to automatically regulate energy use based on times of day or occupancy levels.  Humidity Control Systems: A building’s humidity level plays a strong role in occupant comfort, mold growth, and heating and cooling efficiency. Retro-commissioning an HVAC system’s dehumidifier and humidity sensors ensures the building stays dry, avoiding problems down the road.  Sprinkler Systems: A working sprinkler system is crucial to a building’s fire safety installations. Retro-commissioning teams can look for broken sprinkler heads, leaking pipes and bad wiring connections that could pose a safety issue during an emergency.  Steps of Retro-Commissioning Here is a breakdown of the retro-commissioning process: Planning: In the planning phase, the commissioning team prescreens a building for energy use, HVAC problems and tenant comfort complaints. It then develops a plan for retro-commissioning the building. Closer investigation: The commissioning team performs diagnostic testing and monitoring to closely examine a building’s energy performance. It documents findings and reviews the results. Implementation: The commissioning team performs necessary repairs and improvements to the building based on testing. Confirmation: The team drafts a final report to confirm what was done in the building. It may give the owners a copy of the retro-commissioning plan. Training: As a last step, training building occupants to use new controls or equipment the commissioning team installed is often necessary.  Revitalizing Existing Structures Although it is common to commission buildings when they are first built, it is also possible to retro-commission structures that need an upgrade. Retro-commissioning helps owners meet performance and energy efficiency targets. It improves occupant comfort, reduces the need for expensive equipment repairs and can significantly lower energy bills.  As properties age and more companies seek to become sustainable, it is more important than ever to breathe new life—and fresher air—into existing buildings. Retro-commissioning is the easiest way to accomplish that.  

Using air conditioners and electric fans to stay cool accounts for nearly 20% of the total electricity used in buildings around the world, according to a report from the International Energy Agency. hybrid work model As a unique mix of key factors, such as the adoption of the hybrid work model and escalating heatwaves in certain regions of the United States keep people indoors for longer periods, this 20% share represents an increasingly costly line item on household budgets. Those within the market are responding by seeking out products that can help them control climates more efficiently. Smart thermostats and inverters Markets for smart thermostats and inverter HVAC controllers are clear illustrations of in-demand technology Given what the industry is experiencing, the markets for smart thermostats and inverter HVAC controllers, which are clear illustrations of in-demand technology, are experiencing growth. But as they do, are the technologies growing together or growing apart? Rapid Growth in Both Markets  Discounts and incentives The smart thermostat market has expanded steadily in recent years, with that growth projected to continue through the 2020s in part due to savings of up to 8% on energy bills homeowners can recoup with the best smart thermostats. The sleek design and digital interface of modern smart thermostats, coupled with the increased control capabilities provided by mobile applications, seem to offer homeowners unprecedented control over their indoor climate. Moreover, the growing popularity of rebate programs providing discounts and incentives is making these solutions even more attractive. Real-time heating/cooling needs with Inverter/VRF Inverter/VRF HVAC systems are capable of adjusting the frequency of the compressor precisely Concurrently, the market for Inverter/VRF HVAC control systems is also expanding. It is estimated that the global Inverter/VRF market will grow from USD $17.6 billion (2020) to $31.9 billion (2025) at a CAGR of 12.7%, with the US identified as the fastest-growing Inverter/VRF market. Unlike their single-speed system counterparts which operate on an on/off or all-or-nothing dichotomy, Inverter/VRF HVAC systems are capable of adjusting the frequency of the compressor to precisely match the real-time heating/cooling needs of an environment. By regulating the fan speed and airflow, Inverter/VRF systems are extremely efficient at keeping an environment at a precisely set temperature.  Enhanced HVAC system performance or not? Given the rapidly expanding markets, one might think that the easy interface of the current smartest thermostats and the operational efficiency of the best Inverter/VRF HVAC controllers could combine to create an exceptionally comfortable and cost-efficient experience for homeowners, and an easily interoperable install for HVAC pros. However, the question remains: have these devices genuinely enhanced HVAC system performance in terms of accuracy, consistency, and efficiency? More importantly, have they made living spaces more comfortable? Have these growing markets and technological advancements made life easier for industry pros?  Persistent and pervasive incompatibility This communication breakdown leads to issues such as set temperature variance, inefficient operation Many are surprised to discover that the response to these important queries is frequently negative and “no”, due to a persistent and pervasive incompatibility between smart thermostats and Inverter/ VRF HVAC controllers. It is this incompatibility that ultimately negates the advanced features and intelligence of each product. This communication breakdown leads to issues such as set temperature variance, inefficient operation, and energy consumption.  Confronting the Critical Interoperability Challenges Ideally, the current smart thermostats, and the benefits they bring such as user-friendly interfaces, would integrate flawlessly with high-efficiency Inverter/VRF HVAC systems, enhancing comfort and cost-efficiency while simplifying installation for HVAC professionals. Unfortunately, this ideal scenario is elusive. The core problem stems from these technologies developing and evolving separately, and in isolated environments. Inadequate two-way communication While individual support for certain protocols may exist, they fail to communicate complex instructions effectively While individual support for certain protocols may exist, they fail to communicate complex instructions effectively due to inadequate two-way communication. When a smart thermostat is improperly paired with an intelligent Inverter/VRF HVAC system, the resulting communication breakdown forces the HVAC system to revert back to single-speed operations, completely undermining its full potential, and sophisticated features. Inefficiency and discomfort Given its prevalence, what does this incompatibility mean for HVAC professionals and their clients? Consider a scenario where a user desires to adjust the indoor temperature to 68°F via a smart thermostat. Since the Inverter/VRF unit can only be adjusted by means of its own communication protocol, and the output of the smart thermostat is a dry contact closure, the 68°F would never be properly relayed to the air conditioner. In other words, the smart thermostat does not provide information on how hard the system is working or the deviation of the current temperature from the desired set point. As a result, the system cannot modulate its output to precisely match the temperature needs of an environment, and the air handling unit within the system is forced to always operate at high speeds creating inefficiency and discomfort.  On-and-off mode Homeowners miss out on the benefits of their investment, and installers find themselves in the predicament Moreover, this style of operation is quite noisy, as the HVAC system drones on at full capacity every time it is reactivated. This on-and-off mode of operation consumes more energy, comparable to stop-and-start gas-guzzling city driving versus smooth highway cruising. Both homeowners and installers bear the brunt of these drawbacks, homeowners miss out on the benefits of their investment, and installers find themselves in the predicament of either explaining this intricate issue or spending valuable time troubleshooting. What Can Be Done to Address Incompatibility?  While this convergence of technology and home comfort presents significant potential and profound challenges, this situation is not without a solution. The industry’s most advanced smart thermostats and efficient Inverter/VRF HVAC controllers both possess impressive capabilities, but the key to success lies in improving their ability to fluently exchange commands and information.  Translator between smart thermostat and Inverter/VRF These remarkable devices contain the unit's protocols, deftly translating the commands of the smart thermostat Thankfully, there are solutions within the market from industry pioneers that act as a "translator" between the smart thermostat and the Inverter/VRF unit. These remarkable devices contain the unit's protocols, deftly translating the commands of the smart thermostat, creating a seamless conduit of communication. Enhancing interoperability Enhancing interoperability is a prevailing trend across the smart home sector, and it is imperative the HVAC industry works to align with this trend. By embracing such changes, HVAC professionals can offer unparalleled value and functionality to their clients while simultaneously reducing installation complexities. This paradigm shift offers a unique opportunity to alleviate their challenges while providing customers with extraordinary value and performance from their HVAC systems. 

It takes a proliferation of data centers to serve the growing computing needs of the Internet, and all those servers churning away create plenty of heat. Might some of that heat be harnessed and used for residential or commercial heating? The emergence of district heating systems, which provide thermal energy to multiple buildings from a single source, demonstrates the approach has broad possibilities. Air-cooled chillers and air-handling units used to cool data centers are like the technologies that cool residences and businesses. They just operate on a larger scale and require a higher degree of resilience and redundancy to ensure data center servers operate without interruption. District heating system The law of physics dictates that the energy you put into a data server will come out as heat, and heat is a byproduct of data center cooling systems. Rather than exhaust that heat into the outside environment, how can it be captured and channeled into a district heating system to heat water and/or to provide warmth to homes and businesses in the same neighborhood as the data center? Law of physics dictates that the energy you put into a data server will come out as heat  Mitsubishi Electric designs engineered solutions that both cool data centers and generate heat output that can be captured for district heating applications. “We want to capture the heat and repurpose it for someone else to use,” says Simon Prichard, Product Strategy Manager for Engineered Solutions for Mitsubishi Electric. Reusing wasted heat from data centers can help to decarbonize heating. United Kingdom's Energy Act 2023 An additional heat pump can be used to increase the “low-grade heat” generated by a data center to the temperature needed for district heating. Alternatively, district heating systems might be upgraded to accommodate the lower-temperature heat from data centers. Additional heat pump can be used to increase the “low-grade heat” generated by a data center. The United Kingdom and other governments globally are promoting the creation of district heating networks. Legislation such as the United Kingdom's Energy Act 2023 identifies areas within England where certain new and existing buildings will be required to connect into district heating networks. Legislation is pushing developers toward district heating and away from the use of fossil fuels. District heating applications Water cooling is a developing technology for data centers, which mostly use air-cooling systems In November 2023, the UK government awarded £36 million to a district heating system in West London that will share data center waste heat with up to 10,000 new homes. Hot air from a data center can provide some of the energy needed for a district heating system, and water-cooling systems can provide even more. Water cooling is a developing technology for data centers, which mostly use air cooling systems. Cooperation is needed to realize the scenario of capturing the heat from data centers for district heating applications. Government legislation can drive requirements to embrace the approach, but the multiple involved parties, including data center operators and the architects and engineers creating nearby communities, must also cooperate. Greater ESG goals Energy must be reused in the geographic area immediately surrounding the data center for the scenario to be financially viable. In an industrial estate, for example, the excess heat could be used for nearby farming; the reuse is not restricted to domestic or residential applications. The various parties tend to be “siloed,” so a concerted effort of “joined-up thinking” is needed to bring all the parties to the table to enable such a system. Construction of new data centers is accelerating, and the centers are getting larger. Construction of new data centers is accelerating, and the centers are getting larger. Currently, 4 or 5% of total electricity output is used by data centers, and ways to reuse that energy are a growing priority for ethical companies in the data center market. Large companies that use data centers are drawn to the district heating scenario to achieve greater ESG (Environmental, Social, and Governance) goals. Moving forward, it behooves everyone to think of data centers as not just generating data but as energy centers generating sustainable energy. Mitsubishi Electric’s products MEWALL mixes high version with energy efficiency, space optimization, and cost-effectiveness “We live in a connected world, and we need data centers,” says Prichard. “The world won’t work without them, but many people don’t know what a data center is and how much we rely on them. Society doesn’t realize how embedded they are.” Among Mitsubishi Electric’s products for the data center market is the MEWALL air handling unit, a “wall” of fans with built-in controls, valves, and filters that are mounted alongside a suite of data servers. MEWALL combines high performance with energy efficiency, space optimization, and cost-effectiveness. Water circulates inside the fans, using cold water produced by a chiller. View of the MEWALL system Smaller data center needs can be addressed using technology such as Mitsubishi Electric’s indoor s-MEXT high-precision air conditioner connected to a Mr. Slim R32 Power Inverter outdoor unit. The indoor unit is customized to the client’s requirements for use in a data center.  At the Data Center World trade show in London in March, Mitsubishi Electric used virtual reality (VR) to provide attendees with a simulated view of the MEWALL system. Given the dimensions of 4 by 2.3 meters, transporting the system to the show presented prohibitive cost and logistical challenges.

The idea of Energy as a Service involves shifting the traditional business model from selling energy as a commodity to providing a comprehensive package of goods and services to address a customer’s energy use and management. Rather than selling energy, the approach encompasses complete stewardship of a company’s energy needs in exchange for a monthly fee. Because 40% or so of a company’s typical energy needs are related to heating and cooling systems, implementing Energy as a Service (EaaS) is tied directly to a company’s HVAC systems. heat pumps and HVAC technologies In the EaaS scenario, an outside company pledges to meet a customer’s energy needs at a discount, say 5%, below what they currently pay. By then strategically seeking to lower the customer’s energy costs by more than 5%, the EaaS company uses the extra margin to pay its own costs and to attain a profit. For example, if a customer’s energy costs can be lowered by 30%, the EaaS company retains 25% every month for the term of the agreement, typically 10 years. Any costs associated with providing the service come out of the 25%. In the EaaS scenario, an outside company pledges to meet a customer’s energy needs at a discount Specifically, working to lower energy costs by that much involves an upfront investment in infrastructure, such as heat pumps and HVAC technologies, to lessen energy consumption. The idea is that the profitability of lowering energy costs will offset even a substantial investment over time. Energy-related infrastructure Briefly stated, that is the business model of Budderfly, which assumes management of a company’s energy infrastructure and becomes the “account holder” with the utility. Once an EaaS contract is signed, Budderfly then invests to upgrade the customer’s energy-related infrastructure, including LED lighting, refrigeration, etc., in addition to HVAC. The goal is to decrease energy usage by 30% or more.  Budderfly typically upgrades the variable frequency drive (VFD) When upgrading the infrastructure, Budderfly “owns” any new infrastructure assets for the term of the EaaS agreement, say 10 years, and amortizes the cost over the timespan. At the end of the term, the assets are turned back over to the customer unless they renew the contract. In the HVAC arena, Budderfly typically upgrades the variable frequency drive (VFD), economizers, and other equipment in a rooftop unit or other machinery when it takes on a new customer. Embraces the EaaS scenario EaaS has a direct incentive to invest in the newest technology to slip the client energy usage “Looking at the opportunity to save 5% of their energy costs, many customers think it seems too good to be true,” says Al Subbloie, President, CEO and Founder at Budderfly. The price of the EaaS contract is based on a two-year review of the customer’s utility bill, which creates a baseline against which the 5% discount is provided. On the consumption side, replacing a rooftop unit with a new Lennox, Carrier, or Trane high-efficiency unit can provide 30 to 40% savings in energy usage. When a customer embraces the EaaS scenario, the EaaS company has an immediate incentive to invest in the newest technology to lower the customer’s energy usage. The more they save on energy, the more they earn in profits. EaaS approach In contrast, in a business model involving energy purchased as a commodity, there is little urgency to upgrade the equipment. That explains why so much equipment currently installed is so out-of-date and energy inefficient, says Subbloie. “We did not expect the infrastructure to be so bad,” he says. “I am sharing something the world is not aware of. As long as cool and hot air are coming out of the vents, no one is looking at the energy impact.” In fact, the EaaS approach is a growing factor in decarbonization. “We are a private capital method to save the world,” says Subbloie. “We are aligning capitalism and putting it to use to save the world (from climate change),” he says. Additional investments by Budderfly Budderfly can make a profit on an EaaS contract if it can achieve 30% savings on total energy costs Subbloie says Budderfly can make a profit on an EaaS contract if it can achieve 30% savings on total energy costs. Of the 30%, Budderfly returns 5% typically to the customer and then spends about 15% on capital improvements, amortized over 10 years. Additional investments by Budderfly include 3 to 4% on technology such as thermostats, metering and controls, and data systems. Other costs are to pay Budderfly’s 300 or so employees.  In the refrigeration realm, which might account for 15 or 20% of energy usage, Budderfly deploys controllers (such as KE2 Therm Solutions and NRM) to smartly regulate the compressor operation in refrigeration units. Door alert monitors and upgraded seals avoid any leakage of cool air. Deploying R-290 (propane) refrigerant systems boosts energy efficiency. EaaS strategy When Budderfly deploys solar systems, the cost becomes just another line on the customer’s bill – there is no purchase agreement or lease involved. Budderfly is transparent with the customer in terms of the money they invest in infrastructure and other costs. In addition to providing the customer with the initial 5% discount, Budderfly also typically shares with the customer half of the proceeds of any energy savings they can achieve above 30%. The EaaS strategy is applicable to a variety of markets, but Budderfly is finding initial success in the quick-service restaurant (QSR) market, where repeatable footprints of individual locations make EaaS calculations predictable and scalable. Probably 80% of their business is in casual dining and QSR installations, including 75 or so well-known restaurant brands; they work with large franchisees who operate multiple brands. top-down relationships Budderfly also has firms in healthcare needs, nursing facilities, office buildings, amenity stores Budderfly is also working to establish “top-down” relationships at the restaurants’ corporate level, which has the ability to impose EaaS as a standard throughout its footprint. “As the climate focus becomes more important, a restaurant brand might say to do it everywhere,” says Subbloie. Hotels and motels are another vertical markets amenable to this approach, and Budderfly also has business in healthcare markets, nursing facilities, office buildings, convenience stores, and other retail. They seek to limit each building’s size to 200,000 square feet or less. Regulated and deregulated rates Budderfly has a team that handles the onboarding of new customers, which involves a short, two-page agreement. Their automated system is connected to 500 utilities, and Budderfly tracks all the regulated and deregulated rates. If rates go up, their billing increases, still based on the 5% reduction that is part of the agreement.  Budderfly benefits from its high-volume acquisition of HVAC equipment at lower prices. “We buy a lot of stuff, we have agreements to buy at volume pricing, and we are constantly negotiating to lower the price,” says Subbloie. “We buy the best of the best to achieve the greatest energy-saving outcome, for obvious reasons. We negotiate prices on the expectation that our volume will make it lucrative (for OEMs).” Subbloie says Budderfly is the largest buyer of roof-top units in the country. Energy-efficient HVAC systems Budderfly’s model enables the facility of the latest and most energy-efficient tools In the scenario of buying energy as a commodity, customers have less incentive to proactively replace their HVAC infrastructure with more efficient models. They also may not have the means to invest in capital improvements to achieve better energy efficiency outcomes. In contrast, Budderfly’s model encourages the installation of the latest and most energy-efficient equipment, and that the equipment is fine-tuned and maintained. By pushing the transition to decarbonization based on an old-fashioned business motive (i.e., profit), Budderfly seeks to jump-start the adoption of more energy-efficient HVAC systems on a large scale. “We have an economic model that is sustainable,” says Subbloie. Investment in AI Budderfly also provides customers with abundant data on their energy usage, including submetering architecture that does 20 to 40 measurements per location.  Each point of energy use reports back every five seconds, providing operational data and suggesting a possible investment in artificial intelligence (AI) to make operations even smarter. 

AHR Expo 2024 was abuzz with activity, befitting a dynamic industry in the throes of change.  Industry developments such as electrification and the refrigerant transition render business opportunities on the AHR Expo show floor, where exhibitors display a determination to meet the challenges and thrive in the process. Walking from booth to booth during the three-day show in Chicago, I saw the best the HVAC industry has to offer, up close and personal. Innovation and adaptability are the watchwords as the industry journeys into 2024 and beyond. Refrigerant Transition Top of Mind  Patented R-454B refrigerant enables a simpler transition without redesigning equipment The technology transition is well underway for OEMs seeking to meet a pending AIM Act deadline at the end of the year. OEMs are choosing to embrace either R-32 or R454-B refrigerant to replace legacy R-410A, which is being phased out. Patented R-454B refrigerant enables a simpler transition without redesigning equipment, while R-32 offers advantages such as higher capacity, higher efficiency, and easier cradle-to-cradle management. Arkema Arkema is the only producer of R-32 refrigerant in the United States. The newer refrigerant is being embraced as HVAC OEMs seek to meet the deadline of Jan. 1, 2025, to use lower-GWP (global warming potential) refrigerants in their products. The technology transition is just part of the AIM Act implementation that will also limit allocation and require refrigerant management. Chemours Chemours is a manufacturer of R-454A, R-454B, and R-454C refrigerants. At AHR, they presented hourly education sessions on a variety of subjects. The refrigerant transition will impact everyone in the industry, including refrigerant producers, equipment manufacturers, contractors, and end users. R-454B refrigerant provides identical performance in HVAC systems compared to the previous refrigerant (R-410A). There is less need to redesign equipment; just adding sensors for leak mitigation can address the mild flammability of A2L refrigerants. Because of the 2025 deadline, 2024 will be the “year of new products” in the HVAC market. OEMs pioneering Innovation  Carrier and others are offering smaller footprints, seeking to meet environmental targets Innovation in the HVAC market is led by companies such as Carrier, which has introduced 100 new products each year for the past eight years. Carrier and others are offering smaller footprints, seeking to meet environmental targets, and providing flexibility for customers. New products include the AquaSnap 30RC air-cooled chiller and the AquaEdge 19MV chiller with low GWP refrigerant to meet pending regulatory requirements.  Copeland Copeland, recently divested from Emerson, also emphasizes innovation, including 12 research and development (R&D) facilities, 1,700 engineers, and more than 3,000 patents. At a press conference at AHR Expo, the 100-year-old company announced it is a “new” company owned by Blackstone Private Equity.  Products featured Among the featured products at AHR are Copeland’s oil-free centrifugal compressor with Aero-lift bearing technology; and Copeland’s CC200 case controller, specifically designed to handle the unique challenges of the current retail grocery refrigeration environments.

To offset the cost of tenants’ monthly electric bills and provide prospective residents with high-quality HVAC upgrades that prioritize comfort and performance, Samuels Associates, owner of the Fenway Triangle luxury apartments, sought a new, building-wide heating solution that was not only cost-effective but also added a modern touch to the building’s extravagance. QMark® MUH-Pro+ and CU900 electric heaters with SmartSeries® Plus (SSP) digital BACnet thermostats from Goodyear HVAC Sales proved to be the ideal solution. Heat in a contemporary design “From their energy efficiency, quiet operation and low maintenance to the fact that they can be controlled individually for personalized comfort, electric heaters offer several benefits in apartment buildings,” explained Andrew Martin, Manager of Product Management with Marley Engineered Products® (MEP). “Delivering supplemental comfort heat in a contemporary design, these heaters are ideal for a variety of spaces including school hallways, church vestibules, transportation terminals, stairwells, entrances, lobbies, mechanical rooms and more.”  Installing Heaters while Maintaining esthetics Buildings boast modern frills and discreet and esthetically good HVAC plans that act quietly Steps away from the iconic Fenway Park, the Fenway Triangle is an 891,000-square-foot complex comprising more than 570 luxury apartment units, as well as an eclectic mix of national and local retailers, restaurants, shops and green spaces. Since opening in 2006, the building needed to address issues with its HVAC systems and controls, which were leading to high monthly electric bills. The culprit? More than 50 outdated competitor electric terminal heaters, which offered only on/off controls and needed to be operated manually. If the maintenance team forgot to shut off the heaters, "The Fenway" would incur the cost of each heater running at full capacity at a rate of about 27 cents per kilowatt-hour. Another challenge facing Fenway Triangle: The emergence of new luxury apartment complexes. These buildings boast modern amenities and discreet and esthetically pleasing HVAC systems that operate quietly. They pose significant competition for “The Fenway”, as tenants increasingly prioritize indoor air quality (IAQ) and HVAC performance when selecting their luxury residences. To remain competitive in the luxury apartment market, investing in HVAC upgrades to replace outdated equipment is imperative. QMark MUH-Pro+ and CU900 electric heaters  Heaters were installed in elevator banks, stairwells, worker lounges, hallways, and facility To combat the rising cost of heating each unit within the building, MEP’s local Sales Representative, Goodyear HVAC Sales, worked with HVAC distributor Equipment Direct Sales, Inc. (EDSI) to provide the client with energy-efficient QMark MUH-Pro+ and CU900 electric heaters from Marley Engineered Products. Designed to maintain occupant comfort and a comfortable environment, the heaters were installed in various elevator banks, stairwells, employee lounges, hallways and inside the building’s recently upgraded building management system (BMS) room.  “Equipped with SSP digital thermostats that provide connections to BACnet MS/TP BMS for easy control and monitoring, the MUH-Pro+ and CU900 units only run when directed by the internal schedule of the BMS,” said Matthew Goodrich, President of Goodyear HVAC Sales. “Use of the BMS saves time and reduces personnel costs by eliminating the need to travel to the heater site. And, if a BMS is not available, the maintenance team can simply use the built in seven-day programmable scheduling feature.”  New electric heating units Cost-Effective Heat for Unmatched Comfort and Lower Monthly Bills In tandem with EDSI, Goodrich and his team installed several brand-new electric heating units in The Fenway’s BMS room to provide cost-effective warmth without taking up floor space or creating a tripping hazard.  “Innovation and collaboration converged as we tailored a custom heating solution, seamlessly blending functionality and aesthetics,” explained Goodrich. “In fabricating this solution for the client, our dedicated team and the coordination of skilled contractors transformed this building into a space that harmonizes comfort and elegance and exemplifies the blending of form and function.”  Full control of the entire heating system The thermostats include features that allow the building’s maintenance team to monitor each heater The success of the project resulted in an extremely satisfied customer. Already, the SSP thermostats have provided cost savings by turning on the heaters only when needed, resulting in less electricity usage throughout The Fenway. Additionally, the thermostats include features that allow the building’s maintenance team to monitor each heater individually from within the BMS room, granting them full control of the entire heating system and eliminating the daily trips previously needed to turn each heater on and off.  “We’re already seeing the savings associated with the upgraded controls,” said John Belmonte, Head of Trilogy Operations for the Fenway Triangle. “Being able to control over 40 heaters locally allows our team to focus on tenant needs without being bogged down by the time it takes to touch each individual unit. We’re eager to work further with the Goodyear team on other buildings in the neighborhood.” Innovative approach and exceptional achievements To acknowledge the innovative approach and exceptional achievements demonstrated by the Goodyear team in overcoming the challenges faced during this project, Marley Engineered Products awarded Goodrich the 2024 Jim Herring Memorial Silver Fox Award at its recent national sales meeting. “This award for excellence in solution design embodies the spirit of Herring, who left a lasting legacy of designing creative solutions for specialized applications, was always up for a challenge and most happy when solving a unique heating or ventilation problem,” said Sean Pesce, Director of Sales for Marley Engineered Products. “Matthew and his team at Goodyear perfectly captured Jim’s talent for finding creative solutions to the most complex issues and left a lasting impression on the client.”

To adequately heat the 111 Murray Street residential skyscraper in New York, the owner sought an effective way to maintain the aesthetic of the mostly glass building without being obtrusive to its design. Custom convection style heaters, mounted in the building’s millwork by Faber Industrial Technologies, proved to be the game-changing resolution. “Convection heaters provide warmth and heat to a specific area or room by circulating air and heating it using a highly efficient electric element,” explained Andrew Martin, Manager of Product Management with Marley Engineered Products. He adds, “Designed for quiet, controlled comfort, they are ideal for both residential and commercial applications, including living rooms and bedrooms, offices, hallways, lobbies, conference rooms, retail stores and buildings with floor-to-ceiling windows.” Installing heaters while maintaining aesthetics 111 Murray Street is a 792-foot-tall residential skyscraper with 156 luxury condominiums Located in the Financial District and Tribeca neighborhoods in Lower Manhattan, 111 Murray Street is a 792-foot-tall residential skyscraper with 156 luxury condominiums and 2,100 square feet of retail space on the ground floor. Due to mechanical constraints exacerbated by the building’s slim design, hot water was not available in most of the upper residences, rendering hydronic heating systems impractical. Therefore, the client requested Berko ASL3 convector heaters from Marley Engineered Products to be installed for elegant, supplemental comfort for heat loss, condensation prevention and continuous warmth throughout each condo. The challenge, however, came from their preference to keep the heaters hidden for aesthetic reasons. “The varying heights and angles of the millwork in each condo limited our ability to install the heaters directly where we wanted them,” said Christopher Smith, a Heater Manufacturing Representative with Faber Industrial Technologies, adding “Therefore, we needed a custom design that enabled us to mount the heaters properly while also keeping them out of sight.” Hidden Heat for Unmatched Comfort and Elegance The solution involved fabricating and supplying custom dual inlet convector heaters, which were then mounted within the millwork of each condominium unit. Using a thermocouple array, the engineering team at Marley tested the Berko ASL3 convectors – at 125 watts per foot and 120V – inside a customer-supplied demo millwork section sent from New York City. After making some adjustments to the design, thermal couplers were utilized on both the heaters and their enclosures to ensure their surface temperatures were within Marley Engineered Products’ limits to pass a UL site inspection. Berko ASL3 convector heaters The result was an ‘invisible solution’ in which none of the controls or heaters could be seen in the residential units Next, Smith coordinated with the electrical and mechanical contractors on-site to fit the heaters into each condo’s temperature control system using power relays. The result was an ‘invisible solution’ in which none of the controls or heaters could be seen in the residential units. “Innovation and collaboration converged as we tailored a custom heating solution, seamlessly blending functionality and aesthetics,” explained Christopher Smith, adding “In fabricating this ‘invisible solution’ for the client, our dedicated team and the coordination of skilled contractors transformed these condos into spaces that harmonize comfort and elegance and exemplify the blending of form and function.” Berko ASL3 convector heaters The success of the project not only resulted in an extremely satisfied customer, but also left the contractors pleased with the uninterrupted delivery and installation of the heaters. They were further impressed when the custom heater and millwork system passed the UL site inspector’s test after just one evaluation. To acknowledge the innovative approach and exceptional achievements demonstrated by the Faber team in overcoming the challenges faced during this project, Marley Engineered Products awarded Smith the 2023 Jim Herring Memorial Silver Fox Award at its recent national sales meeting. Solving unique heating or ventilation problems “This award for excellence in solution design embodies the spirit of Herring, who was always up for a challenge and most happy when solving a unique heating or ventilation problem,” said Sean Pesce, Acting Director of Sales for Marley Engineered Products. He adds, “Chris and his team perfectly captured Jim’s talent for finding creative solutions to the most complex issues and left a lasting impression on the client.”

Kepier School's phased transition to low-carbon CIAT heating technologies has delivered generous energy savings within a year of installation. CIAT worked with partners to initiate the school’s journey to net zero in 2022, returning to measure performance and optimize the system. CIAT is a part of Carrier Global Corporation, a global pioneer in intelligent climate and energy solutions. New high-efficiency heat emitters CIAT worked with BREng Hull Ltd, AA Projects, Quora Group, and Cool Designs Ltd to create a phased decarbonization plan for Kepier School in Northeast England, aided by the Condition Improvement Fund (CIF). Recognizing the challenges faced by many schools, Oliver Sanders, Carrier Commercial HVAC Director, United Kingdom, and Ireland, said, "For schools with new gas boilers aiming to reach net zero, it's most cost-effective to integrate them into a modernized heating infrastructure, ready for the next transition phase to heat pumps when the boilers reach end-of-life." Project featured a heating audit The project involved a heating audit identifying the need for new high-efficiency heat emitters The project involved a heating audit identifying the need for new high-efficiency heat emitters. Conventional radiators were replaced with seven surface-mounted high-level CIAT MajorLine and 31 CIAT COADIS fan coil units (FCUs). The seven gas boilers installed in 2019 were integrated into the new system's infrastructure, enabling them to be replaced as required to improve system efficiency and cost savings. Sizeable energy savings A subsequent review revealed sizeable energy savings. Gas usage was compared before and after the pandemic to avoid skewed data due to COVID-19 school closures. Findings revealed an 8.6% reduction of 2,824 m3 (~31,446.41 kWhr) from March 2022 to March 2023 compared to the period from March 2019 to March 2020. This achievement reduced the school’s carbon footprint and resulted in an 8% annual cost saving of ~£800 (average based on gas price fluctuations between March 2019-2020 and March 2022-2023). CIAT project partners BREng Hull  CIAT project partners BREng Hull and installer Quora Group returned to the school to optimize system operating gains Following commission, CIAT project partners BREng Hull and installer Quora Group returned to the school to optimize system operating gains.  "The process doesn’t stop once a solution has been designed, installed, and commissioned," said Rob Smelt, Managing Director of BREng Hull, adding "Experience shows that there are often significant additional gains to be made by optimizing the system in light of its real-world operation." The inspection revealed that some areas were imbalanced while others operated at sub-optimal temperatures. These issues were addressed to improve occupant comfort and reduce energy use and running costs. Carrier’s 2030 ESG Goal "The comfort level has improved significantly," said Brian Dixon, Kepier School Estates Manager, adding "We already gained control over specific rooms and areas, as opposed to the old ‘on or off’ heating system, and the latest work seems to have improved things even more. Future phases in our decarbonization plan will yield even greater energy and cost savings for the school." BREng Hull worked closely with equipment supplier Cool Designs Ltd during the scoping and specification stages, supported by CIAT application specialists. Projects like these contribute to Carrier’s 2030 Environmental, Social and Governance (ESG) Goal of reducing its customers’ carbon footprint by more than one gigaton.

When the Florida Keys Aqueduct Authority opens its upgraded desalination plant on Stock Island, Danfoss high-pressure pumps and energy recovery devices will radically improve the energy efficiency of a SWRO plant that plays a central role in the Florida Keys water supply strategy.   The Florida Keys Aqueduct Authority (FKAA) supplies 20 million gallons of potable water per day (75.7k m3/d) to its nearly 80,000 customers in the Florida Keys. While most of the water is normally sourced in aquifers, FKAA also operates two seawater reverse osmosis (SWRO) plants for emergency purposes and as a supplemental supply in periods of high demand. FKAA initiated the SWRO plant upgrade FKAA initiated the upgrade of one of these plants, the Kermit H. Lewin Water Treatment Plant located on Stock Island, to increase its capacity, make it more resilient to hurricanes and rising flood levels, and improve its energy efficiency. Since opening in 1980, not only have guidelines for storm protection of such critical infrastructure changed significantly, so has the potential to save on the energy required by desalination. Designed to withstand future floods and hurricanes With sustained winds above 157 mph, such storms can cause severe damage to everything in their path To improve resiliency to extreme weather events in the low-lying Florida Keys, the entire site and facility have now been upgraded to withstand Category 5 hurricanes, the most dangerous level of tropical storms. With sustained winds above 157 mph (252 kph), such storms can cause severe damage to everything in their path. Accordingly, the refurbished facility lifts all electrical and mechanical equipment above the base flood elevation and the expected sea-level rise anticipated by 2060, effectively placing the plant’s desalination operations on stilts to mitigate the risk of severe flooding. improve the plant’s energy efficiency Another key goal of the upgrade was to improve the plant’s energy efficiency at the same time as doubling its production capacity from 2 MGD (7,500 m3/d) to 4 MGD (15,000 m3/d). To bring the refurbished plant up to date and reduce its financial and environmental costs, Carollo, a major U.S. engineering firm specializing in water and wastewater facilities, specified the latest axial-piston high-pressure pumps to replace legacy centrifugal pumps and swapped out old turbines for the newest active isobaric energy recovery technology. Upgraded plant to consist of four RO trains This innovative high-pressure setup dramatically reduces the plant’s energy needs This innovative high-pressure setup dramatically reduces the plant’s energy needs. In the new Kermit H. Lewin Water Treatment Plant being built by Biwater, a world pioneer in water treatment, the RO process-specific energy consumption will be slashed from 25.6 kW/kgal (6.77 kWh/m3) to 8.6 kW/kgal (2.27 kWh/m3). With this improvement, the new plant will be among the most energy-efficient in its class, with significantly reduced electricity bills and greenhouse gas emissions. The upgraded plant will consist of four RO trains, each of which includes two Danfoss APP 86 high-pressure pumps and three Danfoss iSave 70 ERDs. Improvement in energy efficiency In addition to the dramatic improvement in energy efficiency, configuring each train with parallel high-pressure pumps provides additional resilience and other benefits: the smaller pumps are easier to lift and work on, and it is now affordable to keep a spare pump in stock. The new improved plant will come online in Q4 2024. The new Kermit H. Lewin Water Treatment Plant is located just north of the existing plant. Construction began in Q3 2021 and will be completed by Q2 2024. The plant is expected to be fully operational by Q4 2024.

Shadow Industrial (SI), one of the UK’s pioneering infrared heating specialists, has been chosen to refit the heating systems at the London Boroughs of Camden and Islington’s jointly-owned Hornsey Street Refuse & Recycling Center. The decision to use SI’s cutting-edge heaters was made on the recommendation of M&E contractor, Vitalenergi London, which was appointed to update the site’s HVAC. Operational Emissions By 2030 Replacing the building’s 300 m2 existing AmbiRad fan heater system, at just over £25,000, the project will see Shadow Industrial fit 35 of its zero-emission, high-performance heaters across the entire facility. This comes in at a far lower cost, often a 50-75% saving, and increased efficiency than many other alternative electric heating systems. The project will see Shadow Industrial fit 35 of its zero-emission, high-performance heaters Predicted to reduce energy consumption by 80%, this represents a landmark moment for shortwave infrared in industrial settings. Not only that, the replacement of existing heating systems with a low-cost, more sustainable alternative perfectly aligns with both Camden and Islington Council’s Climate Action Plans which seek to achieve Net Zero operational emissions by 2030. Shadow Industrial’s Technology As Graham Hughes from Islington Council says, “When Vitalenergi first introduced us to Shadow Industrial’s technology we were very impressed, particularly by its capabilities and relatively low operational costs." "It’s going to make a massive contribution to our efforts, alongside Camden Council to reduce emissions. We’ll also be able to approach our heating strategy in a far more diverse way, keeping costs down and passing those savings onto taxpayers.” The Heat Is On The technology works by emitting focused radiant heat through precisely-configured reflectors Not only will Shadow Industrial’s heating systems shrink the center’s carbon footprint, but they will also improve energy efficiency. This is predominantly due to the way shortwave infrared works, in contrast to traditional electric and gas-powered central heating. The technology works by emitting focused radiant heat through precisely-configured reflectors. Essentially it heats the person, not the air around them, significantly reducing the amount of heat lost to the atmosphere. This comes into its own in large-span, high-ceilinged structures that experience heavy traffic constantly entering in and out, pioneering to a consistent draft. Wall-mounted or ceiling-hung, directed downwards at individuals, the energy creates a comfortable and instant warmth reminiscent of the gentle heat of the sun. In Control Plug-and-play these light heaters are easy to install and operate, compared to formal systems Plug-and-play these lightweight heaters are easy to install and operate, compared to traditional systems. It’s helping to get a practical and scalable heating network up and running within an industrial facility quickly, with minimal disruption to day-to-day operations. Even better, unlike most gas and electric systems, these heaters can be turned on and off on demand as and when personnel are working in specific areas across the site. The instantaneousness of the heat emitted means it can deliver maximum effectiveness at the click of a switch, and extinguish at the same rate. This means no part of the build is heated unnecessarily. Shadow Industrial’s Heaters As Luke Chappell, Vitalenergi’s lead design engineer (mechanical) on the project says, “Shortwave infrared’s set to be a serious market disruptor in the industrial heating market. It’s a game-changer for local authority and public sector projects, which are both subject to strict sustainability briefs and budgetary constraints." "We cannot wait to see the positive impact Shadow Industrial’s heaters will have on those working within, and managing, the Hornsey Street Refuse & Recycling Center. The Shadow Industrial team has been amazing throughout the process and we looking forward to partnering again on future projects.” Installation of Shadow Industrial’s new system was completed at the start of Q2 2024.
