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...
With the increase in climate protests and UN reports highlighting future net-zero challenges, industries are trying to focus their business practices on principles of sustainable development and responsible investment. In the building sector specifically, landlords are gravitating towards certification schemes such as BREAM, LEED, and WELL (among others) to promote the sustainability of their assets and boost green credentials. Tenants are now demanding that the spaces they live and work in ar...
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...
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...
With the UK committed to reducing greenhouse gas emissions to zero by 2050, drastic action is needed by the government. For new-build homes, there’s a gas boiler ban coming in less than five years’ time. And for older properties, it’s likely that gas prices will continue to rise, to encourage homeowners to switch to a more sustainable alternative. Renewable heating market With this in mind, the renewable heating market is growing rapidly, albeit from a very small base &ndash...
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...
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...
A cooling tower allows building owners and operators to take advantage of low cooling water temperatures and higher rates of heat rejection per square meter inherent in evaporative cooling systems. A well maintained cooling tower enables cooling systems to perform at optimum efficiency, reliably and cost-effectively, with contractors who maintain cooling systems able to service their customers with comprehensive and routine cooling tower maintenance programs that should maintain cooling perfor...
The last 18 months have seen an acceleration in digitalization across many aspects of work and home life. Home spaces have become workspaces, and commercial buildings have had to adapt to changed use and lower occupancy rates. Coupled with this, there is a growing need to dramatically reduce carbon emissions from buildings - according to the International Energy Agency (IEA), the buildings and construction sectors combined are responsible for over 30 percent of global energy consumption, and n...
In HVAC and smart buildings, short-termism is an easy trap to fall into. We live in a world driven by returns, profit, KPIs and results; where short-term goals often trump long term ambitions as individuals at all levels are judged on their immediate targets. It is a facet of human nature that can cause us to be blind to the bigger picture. Yet for companies to operate not only more sustainably, but equally more effectively in the long run, sometimes the big picture needs to take preceden...
As our urban centers grow, so does our demand for key resources, such as energy. Currently, cities are accountable for over 60% of resource use and an estimated 70% of global carbon emissions. In the Middle East particularly, countries have experienced unprecedented population growth, increased economic activity and consequently, increases in energy consumption. Integration of sustainable systems Fortunately, industry leaders and governments are placing sustainability at the heart of regional...
Forget the fact that heat pump installations in the average home could cost several thousand pounds more than a conventional gas boiler and that fully insulating those homes will add even greater cost to the homeowner. It’s not really the cost issue that could be the only potential bump in the road on the way to the target set by the UK Government, because a more pressing problem to solve will be the shortage of trained ‘green’ heating engineers that will be the key to delive...
Utilizing the latest in building connectivity, facility operators can uncover a wealth of data in their systems. The next step comes by leveraging that data with artificial intelligence (AI) and a suite of connected solutions. Data is analyzed to determine actionable items and achieve data-based outcomes that improve efficiencies, allow operators to meet budget goals, hit sustainability targets and deliver on occupants’ expectations. To make those high-level outcomes happen, collecting a...
Now, more than ever, Indoor Air Quality (IAQ) is a major focus concerning the health and safety of students and faculty within the nation’s schools. As they prepare their facilities for a return to in-person learning, school officials are being forced to get an education in the most effective ventilation solutions to help prevent the spread of COVID-19 and other infections. Even without factoring in airborne threats like COVID-19, poor IAQ can negatively affect the health and learning of...
When we think of remote working our thoughts often jump to office workers taking laptops to the kitchen table or of Zoom calls interrupted by needy pets. Remote working, however, isn’t just confined to office jobs. Within the HVAC industry, engineers have been working remotely for large parts of the pandemic thanks to advancements in connected technology and automation of HVAC systems. So, just how has technology enabled remote work in the HVAC industry, and is the rise of the ‘work...
With ongoing efforts from governments across the globe to reduce carbon emissions and with an ever greater focus on sustainability, it is vital that the HVAC sector does its part in becoming more environmentally conscious. And, while there have been steps to become more sustainable, there is a huge amount that still needs to be done to make sure that many of the targets that have been set are attainable. In buildings, both large and small, industrial heating accounts for roughly two thirds of i...
As we continue to grapple with COVID two very clear future objectives have emerged: The need for safer and healthier indoor environments to protect against SARS-CoV-2 and other infectious microbial. Acceleration of UK’s net zero by 2050 plan - 78% reduction by 2035 compared to 1990 levels. Last week a group of world-renowned scientists published a paper entitled ‘A paradigm shift to combat indoor respiratory infection’ affirming the need for improved building ventilation...
The education field was faced with multiple challenges this past year. Not only did the COVID-19 pandemic bring the necessity of online learning, but it has also brought up necessary changes to physical schools and universities, when reopening time arrives. The health and safety of students, staff, and faculty has become a priority for directors of school operations, who have been working to properly adapt school facilities to this new reality we are facing. Ensuring health and safety of studen...
Do HVAC systems help with the spread of COVID-19? No one is entirely sure, but it seems very likely. Especially in the case of enclosed indoor spaces. As soon as the COVID-19 pandemic began, fingers pointed to air-conditioning systems as culprits, and scientists now believe a super-spreader event traced back to a restaurant in Guangzhou, in China, which could have started with an asymptomatic person who just happened to cough close to an HVAC fan. Scientists also believe something similar happe...
It’s no secret that climate change is one of the most pressing concerns facing our planet. We must act collectively on behalf of future generations to enact the change that will help us to avoid a climate catastrophe; and not least the HVAC industry, which has been, and remains, a major contributor to atmospheric greenhouse gases and global warming. In 2015, the UK Government, along with 196 parties entered the legally binding international treaty on climate change, which was adopted at C...
Over the last year, we’ve become all too familiar with the risk posed by a deadly airborne virus, but, as we move out of lockdown, there are other airborne hazards we urgently need to fight. However, while advice and guidance are abundant in the use of heating, ventilation, and air conditioning systems in combating the spread of COVID-19, there has been very little said of the risk of using HVAC systems after a prolonged period of inactivity. As those familiar with HVAC systems know, air...
In the coming decades, the government plans to phase out gas and oil boilers and replace them with renewable heating systems. To make this possible, to give us a shot of achieving net-zero carbon emissions by 2050, more people need to train as renewable heating installers. But when you were a teenager, if old people like Boris Johnson or George Eustice had told you that you ‘should’ choose a certain career, would you have listened? No, me neither. Yes, there will be plenty of enviro...
Over the past few years, hydrogen has been dubbed the savior of residential heating and a major part of the plan to achieve carbon neutrality, yet new research suggests hydrogen should be reserved for the likes of aircraft and industry. As part of the 2016 Paris Climate Change Accord, the economies agreed to keep global warming under 2°C. A key part of achieving that has been an agreement to become net zero on greenhouses gases by the year 2050. Renewable heating method With heating curre...
