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 reason. A 2021 survey from The Colling Media Snapshot asked homeowners across the US about preventative maintenance. The survey stated that during the last time they had an HVAC service, 41% of homeowners had a preventative maintenance inspection of their HVAC system. The importance of preventative maintenance is resonating with homeowners and commercial property owners are no exception. Below are three reasons why commercial property owners and managers should keep preventative maintenance top of mind: Tenant Satisfaction Preventative maintenance can affect the satisfaction and the length of stay of residents For commercial property owners, tenant satisfaction is a top priority. Preventative maintenance can affect the satisfaction and the length of stay of residents. The Rental Protection Agency states that repair problems are the third most common complaint in residents nationwide, which includes heating and cooling. Busy season for contractors occurs during the hot summers when outside temperatures are extreme and homeowners are excessively running their units. The typical HVAC contractor carries a backlog of 2-3 weeks’ worth of work during the busy season. Summers without air conditioning can be miserable for residents and detrimental to a building’s reputation and retention if system failures are not fixed quickly enough. Staying on top of preventative maintenance is a proactive strategy to mitigate emergencies. Capital Planning Planning for routine services is important for all HVAC owners and operators as neglecting preventative maintenance can devastate a budget. This is especially true if you are a commercial property owner or manager as overlooking preventive maintenance could cause failure to multiple HVAC systems and exponentially increase the cost of repair and throw a property owner even further out of budget. In addition to reducing last-minute emergencies, keeping the maintenance and replacement history of a building’s HVAC systems is important when it is time to sell a commercial property. How well a system is maintained can affect the sale price of a property, especially as buyers from the coasts expect up-to-date HVAC systems. Data-Driven Decision Making IoT coupled with sensors and wireless networks provide perspective into both predictive and prescriptive analytics In commercial properties, HVAC systems consume more than 30 percent of the total energy use of a building. The Internet of Things (IoT) coupled with sensors and wireless networks provide perspective into both predictive and prescriptive analytics that can assist in decision making. With this data, building owners and maintenance techs can understand which systems are consuming the most energy, which ones are the most energy-efficient, and can identify when systems are breaking down. These actions provide a runway of time to proactively fix system failures before the cost to repair is greater than the cost of replacement.
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 technology. Yet, it has now become a necessity, as energy efficiency becomes a more prominent topic discussion, which is leading to sweeping changes across all aspects of our lives and none more so than in the built environment. Commitment to net-zero emissions Governments are beginning to impose tighter restrictions on building use, energy consumption and emissions. Policymakers around the world are committing to net-zero emissions targets, with more than 60 countries pledging to achieve carbon neutrality by 2050. For example, the European Union (EU) is committed to become a carbon-neutral economy, with net-zero emissions by 2050 and all new buildings within the EU must be constructed as near-zero energy buildings. Meanwhile, China has legislated that at least 30 per cent of all new buildings must be ‘green’. Smart technology to better manage HVAC Technology can help optimize energy consumption and create energy efficiency in our buildings Given this new trend towards energy efficiency in the real estate sector, smart technology is needed to better manage HVAC and energy consumption. Buildings currently contribute 40 per cent of global carbon emissions, a problem exacerbated by extreme weather conditions across the globe, which increases demand for electricity, as more people rely on air conditioning for cooling. Technology can help optimize energy consumption and create energy efficiency in our buildings, alleviating many of the problems that we have today. Technology enabled by the Internet of Things (IoT) can optimize comfort and safety, while providing remote operability and access to everything from HVAC systems to security cameras. At the same time, data collection and integration with cloud-based services allow for powerful energy efficiency measures. Designing and operating Smart buildings The concept and operation of smart buildings is not new. Architects and developers have been installing separate systems to control lighting and HVAC for decades. Later systems have evolved and helped building managers control access to different areas of a site, mitigate fire risk and protect against power surges. What is new is the addition of web-based platforms, in order to allow these verticals to integrate seamlessly with each other. The building of tomorrow is achievable today, using the latest in automation intelligence to control lighting, air-conditioning and heating. With these digital solutions, everything can be controlled remotely and allow for complete control, whenever it is needed most. Increased use of smart technology The first step in managing HVAC energy is to understand exactly how much is being used and where it is used. With this information at hand, managers can highlight areas for improvement, which in turn will help a building become more efficient and ultimately, save money. Another step in managing HVAC energy is including smart technology alongside your system Another step in managing HVAC energy is including smart technology alongside your system, as it can minimize maintenance costs. Predictive fault-finding can save maintenance time and labor, as well as minimizing downtime for expensive equipment or services. It is estimated that smart-enabled predictive maintenance is three to nine times cheaper than a traditional reactive approach. Tenant and occupant satisfaction are often also higher, as systems that experience failure can be identified, repaired and re-booted quickly. Smart building systems Smart building systems, such as ABB i-bus KNX ClimaECO and ABB Cylon BACnet solutions, can combine HVAC in one holistic solution, from central control and management of heating and cooling systems, down to room-level automation. Smart systems simplify the implementation of intelligent automation in modern buildings and using pre-installed algorithms, can make autonomous decisions on things, such as adjusting lighting and HVAC levels, to reflect time of day, external environment, occupancy levels or other variables. Additionally, data collection and data analysis enabled by IoT allows for increased knowledge and better predictions of use. Working with a smart building, which is interconnected, can act and learn on this data, while providing remote access to data and analytics for human oversight. The ROI of smart technology implementation In addition to legislation driving change, being ‘smart’ provides other real benefits for developers and owners. As a building adapts to the demands of its users or the goals of its managers, it can save energy, cut emissions and reduce energy costs. More effective and efficient use of power can save money, quickly repaying initial technology expenditure Comparing energy savings to the falling cost of installing a basic smart management system, smart buildings immediately prove their worth. According to HSBC, if a smart system delivered an energy cost saving of 25 per cent, on an installation cost of US$ 37,500, for a 50,000 sq. ft building, the annual savings could be as much as US$ 23,000, giving a payback period of less than two years. More effective and efficient use of power can save money, quickly repaying initial technology expenditure. HVAC and lighting alone can account for about 50 per cent of energy use in an average commercial building, but by incorporating smart automation, managers may see decreased energy costs of up to 30 to 50 per cent. Leading the fight against climate change Technologies, such as IoT and Artificial Intelligence (AI) are crucial to help us in the fight against climate change. These technologies help users, owners, operators and facility managers interact with the buildings of the future effortlessly, with personalized comfort and maximum efficiency. Artificial Intelligence and IoT is constantly in a state of evolution, as more applications for the technology are discovered. Given the ever-changing nature of technology, the possibilities for smart buildings in the future are endless.
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. Typical supermarket products With refrigeration sitting at the heart of some of the biggest industries across the globe, including food commerce, healthcare, manufacturing and technology, decisions on refrigerant technology tap into the heart of the debate around environmental credibility, consumer expectations and economic recovery. So how can businesses balance the need to adopt more environmentally-preferable refrigerants with the urgent need to boost revenues? The technology factors into many of the most important facets of modern society Often when you think of refrigeration, you instantly think of cold storage and supermarket refrigeration. Without refrigerants, we wouldn’t be able to extend the life of many typical supermarket products or have the convenience of home storage. However, that isn’t the only role refrigeration play in our daily lives. In fact, the technology factors into many of the most important facets of modern society. The healthcare sectors, for example, would struggle to reduce the spread of infection without the use of modern air-conditioning, while the pharmaceutical industry requires refrigeration to store life-saving medications. Preserving human life On top of this, the digital revolution would not be possible. Without coolants, the data centers run by companies such as Amazon, Facebook and Google would overheat, resulting in system failures and service outages. And finally, with temperatures rising across the planet because of global warming, and heatwave events becoming more common, refrigeration is increasingly important to preserving human life. Without refrigerants, recent extreme weather events would have been even more devastating. However, although refrigeration has been a solution for many human challenges, finding a refrigerant that is both safe and environmentally preferable is a challenge. In fact, before recent breakthroughs, many of the chemicals used as refrigerants, such as ammonia, sulphur dioxide, carbon dioxide and methyl chloride, were poisonous, corrosive and even explosive. Non-Flammable alternative CFCs were found to be extremely harmful to the ozone layer and were therefore phased out In the 1930s, a compound called chlorofluorocarbons (CFCs) was commercially introduced as a non-toxic, non-flammable alternative to established refrigerants and was in widespread use for a variety of applications by the mid-20th Century. However, CFCs were found to be extremely harmful to the ozone layer and were therefore phased out in favor of hydrofluorocarbons (HFCs). The story wouldn’t end there, however, as HFCs were found to be potent greenhouse gases with high global warming potential (GWP). EU regulators therefore demanded their phase-out from 2016. By 2024, HFCs must be phased out so industries have been scrambling to find alternative low-global-warming-potential solutions. Unique chemical bonds The answer came in the form of hydrofluoroolefins (HFOs), developed by renowned chemist, Rajiv Singh. HFOs are known for their unique chemical bonds, which allow them to break down in just a few days, so they don’t linger in the atmosphere if released and therefore don’t meaningfully contribute to global warming. Since launching its Solstice line of HFO refrigerants in 2012, Honeywell has averted the production of more than 200 million metric tons of greenhouse gases, equivalent to emissions from more than 42 million cars, more than all passenger cars in Germany. Honeywell has averted the production of more than 200 million metric tons of greenhouse gases The automotive industry was one of the first sectors to recognize the strengths of HFOs. During the past 10 years, nearly 75 million cars made in Europe have been fitted with HFO-based air conditioning systems. Supermarkets have also been reaping the benefits; more than 30,000 grocery stores currently use Honeywell’s non-flammable HFO refrigerant, Solstice N40, reducing their energy consumption by 10% and their global warming potential by a factor of three. Residential heat-Pumps HFOs are on the brink of being adopted for domestic use as well. New Honeywell HFO solutions are ideal for residential heat-pumps which enable the elimination of fossil fuel burning in our homes, for heating and for hot water generation. HFOs superior performance deliver ‘best-in-class’ energy efficiency, hence enabling heat pumps to generate more renewable energy from the waste heat vs. alternative solutions. As enablers for energy efficient solutions and systems, HFOs also offer unique opportunities for future developments such as domestic air conditioning, cooling of electronic vehicle batteries and the fast growth of data center cooling. The ‘Green Deal’ is EU flag ship regulation on climate and economy recovery. Overall, buildings are responsible for about 40% of the EU’s total energy consumption, and for 36% of its greenhouse gas emissions from energy. Greenhouse gas emissions These new regulations and the corporation sustainability goals create a range of new opportunities To make it specific, heating and cooling, in the EU is responsible for 80% of energy consumed in residential buildings. Rapid adoption of Heat pumps and improved energy efficient solutions; are key contributors for Europe to reach the ‘Green Deal’ goal of being carbon neutral by 2050 and the recently adopted accelerated ‘fit for 55’ goal to reduce net greenhouse gas emissions by at least 55% by 2030. Adopting Low Global warning refrigerant, safe & energy efficient cooling solutions and replacing fossil fuel burners with heat pump systems to generate heat; are also key contributors to corporations’ sustainability goals (ESG). These new regulations and the corporation sustainability goals create a range of new opportunities for HFO solutions. As the popularity of HFOs grows, they’ll have a major role in mitigating climate change and enabling a carbon neutral economy. Pharmaceutical supply chains Happily, what’s good for the environment is also good for the economy. HFO production is already creating thousands of long-lasting jobs. The global pandemic stopped many people from enjoying a range of everyday pleasures such as visits to sporting events, restaurants and cinemas; activities at venues that are often reliant on some form of air conditioning and refrigeration, a sharp reminder of the role played by modern refrigerants. The technology continues to develop and evolve ensuring that a range of activities can continue to happen. From protecting the food and pharmaceutical supply chains to ensuring the continued operation of modern communication technology, next generation refrigerants will support some of the most important parts of the modern economy and a better environment.
After extensive research, testing, and evaluation, Johnson Controls, the provider of smart, healthy, and sustainable buildings, has selected R-454B, a lower global warming potential (GWP) refrigerant, to replace R-410A in its ducted residential and commercial unitary products as well as air-cooled scroll chillers. Systems using the new refrigerant will be available for Johnson Controls, YORK®, Luxaire®, Coleman®, Champion®, TempMaster®, Fraser-Johnston®, Guardian®, Evcon™, and Quantech® branded products in North America, as well as specific international markets where codes are in alignment. High-GWP refrigerants This decision was made as the HVAC industry is preparing to phase out high-GWP refrigerants, such as R-410A, which are now being formally addressed by the Environmental Protection Agency (EPA) through the recently passed American Innovation and Manufacturing (AIM) Act. The AIM Act directs the EPA to phase down U.S. hydrofluorocarbon (HFC) production and use by approximately 85 percent over the next 15 years. Johnson Controls has determined R-454B be the best-in-class replacement refrigerant After evaluating several low-GWP alternatives on a variety of performance and market metrics, such as safety, capacity, efficiency, reliability, availability, and longevity, Johnson Controls has determined R-454B to be the best-in-class replacement refrigerant – a decision echoed by other HVAC manufacturers. R-454B has the lowest EPA SNAP approved GWP for unitary applications of all ASHRAE classified A2L (low-toxicity, mild flammability) refrigerants on the market, coming in at 466. Maximizing environmental benefits This is one-fifth the GWP of R-410A, far lower than the pending 750 GWP limits being proposed and offering the longest-term viability. “Utilizing R-454B was a clear decision, but one that took years of in-depth research, testing, and evaluation,” said Chris Forth, Executive Director of regulatory, codes, and environmental affairs, Ducted Systems, Johnson Controls. “This decision maximizes environmental benefits, which will help to avoid, if not completely avert, a second, near-term transition for the unitary sector. As the AIM Act phase-down schedule progresses, higher-GWP fluids such as R-32, while viable today, have the potential to be eliminated as an option due to their high-GWP values. Johnson Controls will continue to evaluate lower-GWP alternatives for future possibilities.” Improving system efficiency Existing R-410A equipment built prior to that date can be sold and installed indefinitely" In addition to reducing environmental impact, R-454B is more compatible with existing R-410A equipment designs, requires a less or similar refrigerant charge, and can reduce the energy use of HVAC systems and improve system efficiency. The similar operating characteristics with R-410A will make for a smoother transition for distributors, wholesalers, and contractors. “It’s important to note that these pending mandates from the EPA and the California Air Resources Board (CARB) would only apply to the sale of new residential and commercial unitary equipment as well as air-cooled scroll chillers. As the pending regulations stipulate a specific manufacturing cutoff date of January 1, 2025, for residential and light commercial unitary products and January 1, 2024, for air-cooled scroll chillers, existing R-410A equipment built prior to that date can be sold and installed indefinitely,” said Forth. Rule-Making processes “EPA and CARB are scheduled to begin their formal rule-making processes this year, which will determine how long of a servicing period will be granted for R-410A equipment currently in service.” As we approach the refrigerant transition cutoff dates, safety standards and building codes must be updated prior to a widespread market introduction of mildly flammable, low-toxicity A2L refrigerants such as R-454B. Extensive, multi-year research and testing have been conducted by ASHRAE, AHRTI, and others to ensure A2Ls can be safely deployed. Proper training will be critical to ensure the safe use, transportation, and storage of A2L refrigerants. Johnson Controls is committed to ensuring the safe transition to R-454B by providing in-depth training for its contractors and technicians prior to the pending refrigerant transition dates.
