HVAC Efficiency Enabled By The Smart Buildings Of The Future
HVAC Efficiency Enabled By The Smart Buildings Of The Future

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.

Here's How HVAC Contractors Can Navigate Shortages
Here's How HVAC Contractors Can Navigate Shortages

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 disrupted several critical links in the HVAC manufacturing supply chain. Various raw materials The most significant have been shortages of various raw materials, including aluminum, copper and plastic, and a notable lack of semiconductors. The semiconductor shortage has had a particularly broad impact on industries of all types. Right now, any industry that uses power electronics — from automakers to graphic cards manufacturers — is struggling to source enough chips to meet demand. The semiconductor shortage has had a particularly broad impact on industries of all types Many economists and industry observers are unwilling to make predictions about when the shortage will end. However, some have estimated that it could be as late as 2023 before semiconductor production returns to normal. Industries that produce raw materials needed for essential HVAC equipment may face similar recovery timelines. Salvaging working parts Consumer confidence is growing, and demand is returning to more normal levels as the pandemic begins to end. These market conditions could mean a quicker return to business as usual for these essential industries — but HVAC professionals should probably prepare for shortages that last well beyond 2021. There are a few strategies individual companies and contractors can use to outmaneuver these shortages. Temporary replacement components Loaner A/C units and temporary replacement components can bridge the gap when repairs are necessary Offer loaners and temporary repairs - Loaner A/C units and temporary replacement components can bridge the gap when repairs are necessary but customers aren’t interested in waiting for a new part. You may be able to offer loaner components or window units that can help keep customers cool. Salvaging working parts from systems your business replaces can give you a stockpile of functional, used items you can use for temporary repairs. These fixes will not last as long as a new part or complete HVAC system replacement. Still, they can provide a valuable stopgap when options are limited or customers aren't interested in more extensive work. Preparing reverse logistics Communicate with suppliers - Some manufacturers reduced component stockpiles to a minimum before the pandemic and have few spare components as a result. Others continued to buy items and may have parts on hand for contractors who need replacement components immediately. Communicating with your suppliers will let you know if rush orders are a possibility. In some cases, you may not have to worry about long lead times for every part, but only for specific components or products. Communication will also help you better prepare your reverse logistics Many HVAC businesses are also building stockpiles of their own, ordering parts and components well in advance to cover anticipated needs. Knowing which components or products are likely to require long lead times will help you inform your customers and get ready for repairs more effectively. Communication will also help you better prepare your reverse logistics — the processes you use to return unneeded or unwanted parts to suppliers. Good working practices Prioritize safe and sustainable work - Now is the time to make safety even more of a priority than usual. HVAC businesses can struggle in good times if a key employee is injured on the job. Independent contractors likely can’t afford the missed work that an injury may mean. The correct PPE and good working practices will help keep workers safe and encourage them to stay, making it easier for companies to avoid the HVAC skills gap. Safety will be especially important on hazardous job sites, like active construction or demolition areas. Following safety best practices for those locations will help keep you and your team safe. Cleaning condenser coils Teaching people how to safely clean their AC unit could provide similar benefits Let customers know how they can help - Communication with regular customers can also be key. It’s not unusual for someone to wait until their air conditioner has stopped working to schedule maintenance. As a result, issues with HVAC system components will typically not be noticed until they have failed or started to cause problems. It also means customers will miss out on maintenance that could reduce the strain on an HVAC system — like changing filters and cleaning condenser coils. Teaching people how to safely clean their AC unit could provide similar benefits. Encouraging regular maintenance and offering deals on services can keep their systems running for as long as possible without repairing or replacing components. Proactively informing customers about the long lead times needed for new or replacement parts may help you communicate why this upkeep is so important right now. Navigating the shortage Enable customers to upgrade their repairs - Other strategies that encourage customers to invest in replacements rather than repairs can help offset the higher costs of HVAC equipment. Second chance offers and similar deals allow customers to credit the cost of a repair against a replacement unit. These offers mean that even if customers choose to repair rather than replace a system, they can change their minds without losing the money spent on the initial fix. HVAC contractors should be willing to pass along these increases to customers Be willing to shift - Prices for HVAC equipment are likely to remain high during the shortage, and business costs will be higher as a result. HVAC contractors should be willing to pass along these increases to customers. Building in higher expenses for components and essential resources to your pricing will help you navigate the shortage. HVAC equipment shortage Anticipate related equipment and parts shortages - Your business should also be preparing for related problems — like the ongoing shortages of vinyl car wraps or replacement auto parts. Fleet vehicles that need repairs may be out for days or weeks at a time. Maximizing the lifespan of all business equipment with preventive maintenance will help keep the business running in the long term. The HVAC equipment shortage is likely to last well into the future — potentially as late as 2023. Businesses and contractors should prepare for rising costs and long lead times for new components and systems. To adapt to these new market conditions, companies may want to readjust their pricing schedules and change how they communicate with customers and suppliers. Proactive communication that prioritizes transparency will help businesses make the most of supplier relationships and let clients know what they should expect.

The Role Of Next Generation Refrigerants In Economic And Environmental Recoveries
The Role Of Next Generation Refrigerants In Economic And Environmental Recoveries

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.

Friedrich Air Conditioning Discusses The Benefits Of Installing Portable Air Conditioners For Hot Summers
Friedrich Air Conditioning Discusses The Benefits Of Installing Portable Air Conditioners For Hot Summers

Portable air conditioners have become a popular summertime cooling solution, valued for their easy, non-intrusive installation, fast set up, and the ability to easily store them away after the summer season ends. There is no end to the possible applications for a portable unit. Bedrooms, sunrooms, workout rooms, garages and other areas where relief is needed from the sweltering summer months are a great place to use a portable AC. Even homeowners with central AC will be glad to have one of these units on hand when the central AC breaks down during a summer heat wave and the first available service call is several days away. Ready to shop for a portable? Here are some factors to keep in mind when choosing a portable unit. As with any other air conditioner, one needs to know the square footage of the space they want to cool. Most portables will list a recommended square footage for the unit’s capacity. Portable air conditioners Single hose or dual hose portable? Getting the right BTU capacity for the space is critical. One will find several models rated for areas up to 500 square feet. Keep in mind that a space that has multiple sun-exposed windows, a heat producing appliance, or routinely has multiple occupants will have added heat load. If any of these conditions are present, one will want added BTUs to stay cool. Portable air conditioners are either single hose or dual hose design. Single hose models are faster to set up and may have built-in hose storage, so they are easily stored away once the season ends. They’re a great choice for spot cooling or in areas that have moderate summers. However, single hose models, by design, must intake and exhaust air through the same hose. Warm outside air is mixed in with indoor air and over time will produce a ‘warming effect’ if outdoor temperatures are extremely high (above 950 F). permanent cooling solution Is there a window to vent air to the outdoors? The kit has either one or two expandable hoses, and a frame that fits into the window with knockouts for the hose On two-hose portable models, one of the two hoses is dedicated to removing heat (exhaust) and expelling it outside. Intake air comes from the room that is being conditioned so the unit will maintain comfort even in extreme heat. Dual hose portable air conditioners will cool more quickly and efficiently. Dual hose portables are a great choice for all climates and are even suitable if one will be using the unit as a permanent cooling solution. Portable air conditioners must be vented to the outdoors. The units come with a window installation kit. The kit has either one or two expandable hoses, and a frame that fits into the window with knockouts for the hose(s). The hose kit will install into most standard windows. The hoses snap or twist and lock into the kit frame and into the back of the unit. Most flexible hoses can extend from 24-60 inches. installation kit hoses Is there a proper electrical outlet near the window? Venting through a drop ceiling may be an option in certain circumstances, however additional hose(s) may be necessary to reach ceiling height. One will also want to make sure the ceiling opening is well sealed to maintain proper cooling and venting of hot air. Portable units will plug into a standard 115v wall outlet, but one will want to make sure the wall outlet is close enough to the window so the power cord of the unit will reach the outlet, and the unit remains close enough to the window to utilize the installation kit hoses. Otherwise, one will have to hire a qualified electrician to install the outlet. Typical power cords are 6-7 feet in length.

Portable Technology Brings Cooling Solution To HVAC Market That Offer Spot Cooling And Supplemental Air Conditioning
Portable Technology Brings Cooling Solution To HVAC Market That Offer Spot Cooling And Supplemental Air Conditioning

Traditionally, portable cooling technology has been seen as a quick fix to immediate cooling needs. If a customer’s air conditioner went out in the busyness of summer, portable cooling could keep the customer comfortable until a technician could arrive at their home. Such needs and uses for portable cooling still exist, but over the past few years, portable cooling has increasingly developed as a solution for unique cooling needs. Manufacturers are saying this trend will continue. Misty Wilburn, Marketing Manager for Portacool, said that the market’s renewed interested in employee safety and productivity is driving further demand for portable cooling solutions. portable evaporative cooling From a safety standpoint, employers are looking for solutions that reduce heat stress and keep their employees cool" “From a safety standpoint, employers are looking for solutions that reduce heat stress and keep their employees cool,” she said. She explained that the industry is seeing a large shift surrounding employee safety. The California Division of Occupational Safety and Health (Cal/OSHA) has led this charge by putting regulations in place regarding indoor and outdoor working conditions and will likely be followed by other states. “For operations that can’t use conventional a/c because of cost or efficiency, portable evaporative cooling - in setting up cool-down stations - can be key to meeting a lot of those regulations,” she said. In addition to this, she said that companies will be able to attract and keep the best employees if they provide a great work environment. open or closed environment “Offering those portable cooling areas can keep up focus and morale, which overall increases the profitability of your workforce,” she said. Wilburn explained that contractors can offer this solution as one that will do the most for their customers while also being conscious of cost. When choosing portable systems for their customers, Wilburn advised contractors to take note of the size of the space that needs to be cooled, the number of employees, electrical options, presence of a water supply, and whether it is an open or closed environment. multiple large coolers “By strategically positioning multiple large coolers, you can cool an entire area where you have lots of employees working,” she said. “If you want to spot cool an area and take the product wherever the work takes you, using one single smaller cooler might be the better option.” In agriculture, portable cooling has been used to cool individual stalls, especially for show animals All in all, she told contractors that it is important to choose a product that is as versatile as possible for the work environments the customers will find themselves in. Contractors should ensure the cooler is a plug-and-play model that can be set up with little technical skill needed. The degree of maintenance required is also important, as well as the expected lifespan of the equipment. Contractors should widen their view of portable cooling applications, too. Portable as Supplemental Cooling “Evaporative cooling is effective in other applications such as farm agriculture, patios, gyms, outdoor venues, events, sports sidelines, offshore platforms, retail stores, rental car pickup facilities, airports, beer gardens, and fast food lines for outdoor employees,” she said. In agriculture, portable cooling has been used to cool individual stalls, especially for show animals. “Is it dependable?” said Brittany Calderon, Product Manager for Friedrich Air. “Is it quiet? Is it energy-efficient? Those are the three main things that we hear our customers looking for. And of course, cost is always a factor.” Portable cooling can be used to keep areas of a home comfortable when the main air conditioning unit goes out. Applications for Portable Cooling “We recommend that contractors all keep a portable in the back of their truck to allow for supplemental cooling,” she said. “If somebody’s a/c goes out and they need to order a part, it’s going to take a few days. They can leave one of those portables at that customer’s house and everybody’s happy.” She said that portable cooling is often used to supplement other cooling systems Calderon said that a dual-hose portable air conditioner offers a really good solution for customer’s needs; it’s designed to cool areas faster, more efficiently, and without a complicated installation process. She said that portable cooling is often used to supplement other cooling systems. For example, 2019 had a relatively mild summer in the Northeast, and Friedrich saw interest grow in portable cooling - equipment that people could stow away in a closet when not in use. electrical equipment rooms Mike Renier, Vice President of Sales for KwiKool, said that customers are realizing that portable cooling can be used for specific, unique applications, and contractors should keep that in mind. “As the market has evolved, customers have gotten more demanding and not less,” he said. “And what that boils down to is that they’re looking for tailor-made solutions to application problems.” Some examples of this, he said, include server rooms, electrical equipment rooms, and other high-tech areas where heat-generating equipment needs to be kept cool. These rooms generally have permanent systems in place to cool the equipment; however, these mechanical systems run the risk of occasional failure when components break. redundant permanent systems The technology, called Biocool, is designed for use in laboratories and hospitals “Customers don’t want to have to spend a tremendous amount of money having redundant permanent systems in place,” Renier said. “As an alternative, they can look to portables to supply the duplicated air conditioning.” To operate as intended, such portable equipment will need to have high-efficiency, sensible capacity that can match the heat load, which contractors should look for. A portable cooler with a 1-ton heat load, he explained, will not be able to cool a room with a 5-ton heat load. Portable technology should always be used with the end goal in mind. For example, KwiKool has developed a portable cooler with a hospital-grade HEPA filter and UV light system. The technology, called Biocool, is designed for use in laboratories and hospitals. temporary air conditioning In other applications, cooled air must be moved long distances before it can be exhausted. Portable coolers, when properly designed to pump air further distances, can be temporarily installed in attics. On hot summer days, when attic temperatures can exceed safe temperatures, a portable cooler can be used to keep the heat tolerable for any employees working in that space. Renier reminded contractors that there is a big division between residential and commercial portable cooling products. “If all you want is some cheap, temporary air conditioning for a bedroom, those personal air conditioners are great,” he said. “But if you want to bring the serious capacity for a high-profile application, don’t buy the cheap stuff. It won’t work. You’re getting what you pay for.”
