Commercial HVAC - Expert Commentary

Poor indoor air quality (IAQ) has been a longstanding problem within educational institutions, where it has been known to affect productivity and performance, as well as mental and physical health. And it’s not just the pupils at risk, with studies finding that this deleterious phenomenon can also compromise teaching performance and delivery, which inevitably affects the quality of the information received. CO2 concentrations This has recently been evidenced in a study conducted by the U...

With the UK experiencing increasingly warmer summers and more frequent heatwaves, we’re equally seeing more air conditioning units installed in both commercial and residential spaces. As the demand for air conditioning continues to increase, so too will the demand for copper pipes. Copper is a trusted and reliable material that air conditioning installers have been using for many years and, not only that, it’s also infinitely recyclable – making it a sustainable alternative to...

A preventive maintenance program could save 12-18% over reactive maintenance, as the U.S. Department of Energy predicted in 2010. For many businesses, the savings could be higher, considering the risks of downtime and today’s economic conditions pushing up costs across the supply chain. It’s also possible for a program to miss the mark. By one measure, 50% of the costs of a preventive maintenance program are often wasted. The question is, how do you know if your maintenance program...

The importance of caring for the environment has become a top priority both around the world and increasingly in the United States. As regulations and social expectations become more stringent, future-proofing our infrastructure - beginning with energy consumption in buildings - is a natural first step. There are four key strategies a building owner or facility manager can focus on to improve energy efficiency and reduce a building’s carbon footprint, all while improving building performa...

Achieving carbon neutrality has, once more, become a business priority. Whilst COVID-19 distracted attention away from the drive towards Net Zero, green issues are once more back on the agenda and rising to the top of it. Building specifications The built environment accounts for around 28-40% of global emissions, so there is a collective ambition to start specifying buildings with as low a carbon footprint as possible. This is particularly true of commercial office spaces where operational...

As COVID-19 becomes endemic and hybrid working becomes the norm, a great deal of time and energy is going into managing a safe return to the office and a move to new styles of working. As hard FM systems are adjusted to suit new workplace expectations and futureproof sites, Johnpaul Pearson, Business Support Director at Anabas, talks about understanding workplaces and using technology to better design and plan a workplace of the future. Even before the COVID-19 pandemic struck, we were witnessi...

‘Energy storage holds the key to providing clean energy for heating and powering the home and reducing carbon emissions’ Carlton Cummins, CTO and Co-Founder of clean technology company Aceleron explain how this will work. As we transition away from natural gas and other fossil fuels, there is no question that we absolutely have to make better use of renewable energy. Using a battery energy storage system (BESS) combined with renewable technology such as solar means that it can be st...

Energy consumption continues to be one of the primary contributors to a building’s carbon emissions and its operational costs. Around 40% of this energy is used to power HVAC systems. To improve sustainability and reduce operating costs, it’s in a building owner’s best interest to find ways to make their building’s heating and cooling systems more efficient. Identifying areas that will make the biggest difference starts with knowing which systems consume the most energy...

Environmental ventilation is an incredibly important element of any building. It uses the natural, external airflow through a building to make the internal climate healthier. When appropriate environmental control is implemented, the benefits include better air quality, reduced CO2 emissions, and lower overhead costs. However, it’s not all sunshine and roses. This presents some issues that must be addressed. Residential buildings often use centralized heating systems, boilers, and ho...

Ventilation systems have never been more important as we battle against an ever-evolving pandemic, and crucially, they must be installed correctly to deliver good indoor air quality for years to come. David Millward, Group Product Manager at Elta Group, explains the practical considerations needed for contractors in charge of installing them. Good indoor air quality (IAQ) With a pandemic that has been raging for going on two years, there has never been a time where good indoor air quality (IAQ...

With COP26 behind us, the words ‘Net Zero’ still hangs heavy in the air as we look to make the most of the momentum gained by the summit. On the face of it, it’s a daunting task. However, like so many challenges in life, it becomes considerably more manageable when broken down into smaller steps. It’s now a widely accepted fact that lighting, heating, and cooling operating emissions account for a significant proportion (28%) of all carbon emissions emitted by building an...

Indoor air quality (IAQ) has never been closer to the forefront of the public mind.  After all, the COVID-19 pandemic is still ongoing. The government’s scientific advisors have warned that, during the coming winter, daily hospitalizations could plausibly reach heights of 7,000 per day. And, of course, we are all thoroughly aware at this point that COVID is an airborne virus and, as such, spreads very effectively indoors – a fact which many people will have reflected on as they...

There are several benefits to using unit heaters in a variety of locations. Whether they are in a home garage or a large commercial warehouse, unit heaters can provide space-saving heating options that can be installed quickly and easily with the right preparation. Unit heaters can be used as a primary or secondary heat source, and the directed warm air of a properly installed unit can make a noticeable difference in the overall comfort level of a space. Unit heater installation Unit heaters...

AI (Artificial Intelligence) is a smart buildings’ biggest ally. Without it, a building could hardly be classed as smart. For building owners and managers, AI is imperative to create a secure and comfortable experience for their occupants every day. What a building platform should do is gather data from various sources from the building management system and other smart technologies, to gather it all in one place. The data should then be fed into a flexible, scalable cloud-based platform...

Even though the COVID-19 pandemic is seemingly drawing to a close, living, working and learning at home is set to continue. Under this new normal, home electricity use is expected to double by 2050. Simultaneously, as climate change devastates communities around the world, we are faced with a moral and economic obligation to cut CO2 emissions from houses. Our goal is to build Net Zero houses and we can't get there fast enough. Fossil fuels use in heating systems Many countries continue to rely...

Seasonal transitions are the perfect time to take inventory and inspect a building’s various systems. We’ve been reminded for years that when we set our clocks back, we should also replace the batteries in our smoke detectors. The same thought process can be applied in support of seasonal preventative maintenance for a building’s HVAC system. Now that the cooling season has passed for a large part of the country, it is time to ensure that HVAC systems have been shut down prope...

I am writing this the day after the Autumn Spending Review, which among many measures, included a huge focus on how the Government wants to ‘level up the country’, creating a new post-pandemic economy, with higher wages and higher skills. Part of this is the £500 million ‘Multiply’ scheme, which aims to increase numeracy and basic mathematics for adults in the United Kingdom via in person tutoring, digital training and flexible courses. Lack of basic skills to acce...

The development of digital technologies in the Heating, Ventilation and Air Conditioning (HVAC) sector has been transformational for the industry, as well as for those who run HVAC systems. While the electrification and digitalization of machines, and assets has made a lot of operations simpler, it has also meant that the collection of machine data has never been more critical. Given that engineers can now view lots of different metrics on a single screen, including things like heating control...

It is now more common to read about cases of Legionnaires’ disease in the media than ever before, with outbreaks regularly being reported in cities around the world, all the time. Many of these cases are attributed to contamination of domestic systems, showers and spas, but some are the result of operating cooling towers. While this problem is not new, with the first reported case in Philadelphia, in 1976, the United Kingdom (UK) has been at the forefront in leading the battle with Legionn...

At the moment, it seems as though a day rarely goes by without low-carbon heating hitting the headlines. Whether it is reports of ‘revamping’ the Clean Heat Grant, to include a ‘boiler scrappage’ scheme, which may offer home owners up to £7000 to make the switch to a low-carbon alternative, to speculation that the Prime Minister is under pressure to push back the 2035 ban on gas boilers, the debate on how and when the low-carbon heating revolution will happen is ong...

Indoor air quality (IAQ) has become an area of emphasis among those in the HVAC industry and on a national level. Homes, offices, schools, and everything in between are being reevaluated with the ambition of having the best IAQ possible. Maintaining a high level of air quality is an important factor in encouraging a cleaner indoor breathing environment, which can lead to the better overall health and well-being of our families and communities. Clean air is especially important now with more wav...

We visit the doctor for yearly check-ups and take our vehicles to a mechanic for maintenance and oil changes. The same idea applies to an HVAC system. An HVAC system can run around 2,000 hours per year and is a building system that is constantly expending energy. Without preventative maintenance, it is much more likely that a building owner could be overlooking silent issues that could cause a system to break down long before it should. Preventative maintenance is catching on for a re...

In today’s world, we spend almost 90 per cent of our time indoors, in our workplaces, leisure areas and our homes. It is no secret that the built environment has been relatively slow in its embrace of information technology and automation. According to KPMG’s ‘Building a Technology Advantage’ report, fewer than 20 percent of construction and engineering executives, and major-project owners said they are re-thinking their business models, so as to incorporate new technolo...

A quick glance at official COVID-19 mitigation guidance reveals that it promotes increased ventilation air change rates, as the most effective way to keep people safe. Sounds easy, doesn’t it? Just open a window or turn up your ventilation system, if you have one. The fact is, however, that the vast majority of domestic properties in Britain does not have a mechanical ventilation system and rely on natural means for background ventilation, including windows, trickle vents or air bricks. In...

Over the last decades heating, ventilation, and air-conditioning systems became significantly more energy efficient. This is immensely important as they are one of the largest energy-consuming loads in commercial and residential buildings. Smooth performance of the systems requires careful installation, thorough cleaning, and regular maintenance. Running an HVAC system (energy) efficiently is challenging because of constantly changing variables: people entering and leaving a building, changing...

The ongoing shortage of HVAC equipment and tools has created a significant challenge for contractors around the country. At the same time, companies are also up against intense environmental conditions, like the extreme winter weather that impacted much of Texas in early 2021. The right strategies can help HVAC businesses navigate this shortage and make the most of the equipment they can order. Due to the lingering effects of the COVID-19 pandemic, raw material and component shortages have disr...

A landmark UN scientific study has once again highlighted the short window available to prevent irreversible climate change. Businesses are coming under pressure to dramatically accelerate their net-zero carbon initiatives. This comes at a time where market dynamism is returning across a range of key sectors following a downturn triggered by the pandemic. Businesses are also being pressured by stakeholders to recover revenues lost during the pandemic and to start rebuilding commercial activity...

The energy transition is upon us and we are shifting today’s energy use to low and zero carbon sources. The way in which we heat and provide hot water to our homes and businesses will change, and we are developing technologies that will support this transition. A bold and pragmatic policy framework will encourage investment and drive change. BEIS Hydrogen Strategy We, therefore, welcome the publication of the Hydrogen Strategy from the Department for Business, Energy & Industrial Str...

In 2019, the UK became the first major economy in the world to pass laws to end its contribution to global warming by 2050 - a landmark moment on the road to net zero. To meet that target, owners and managers of commercial buildings are increasingly facing more standards, regulations, and legislation to promote carbon reduction. This may pose challenges when it comes to investing in building service technologies, but the net-zero goal also provides an opportunity to embrace new approaches to th...

Most people spend about 90 percent of their time indoors. For home owners, indoor environmental quality (IEQ) is the most meaningful differentiator between ‘high-performance’ and ‘code-built’ homes. Indoor environmental quality  IEQ describes how well the indoor environment promotes occupant comfort and health. The components of IEQ include thermal comfort, indoor air quality (IAQ), sound and lighting. Requirements for optimal IEQ vary per occupant and household, d...
