The practice of working from home soared during the coronavirus (COVID-19) pandemic and many observers see a likely continuation of the trend, as infection risks gradually subside. Both environments – home and office – depend on HVAC systems to keep occupants comfortable (and safe!). Therefore, the industry stands to be impacted whichever way the trend plays out. We asked our Expert Panel Roundtable: How will remote working affect residential and commercial HVAC?
The most likely scenario for the next 12 months in the United Kingdom is far lower risk of serious COVID-19 illness due to the vaccine. However, there will be big swings in R rates, and there is uncertainty about how effective vaccines will be against COVID variants. The ‘R’ rate is the number of people one infected person will pass a virus on to, on average. As the scenario plays out, and more companies open for business, issues of indoor air quality will continue to be top of mind...
Panasonic Heating & Cooling Solutions has expanded its technical helpline to provide further customer support with a larger team and a host of new online tools designed to help customers when they need it most. Richard Bishop, Head of Marketing for Panasonic Heating & Cooling Solutions UK and Ireland commented, “During these times of change, we all accept that technical call centers and helplines will be more difficult than normal to reach, the impact of staff working from home is understood and in general we all give a little extra compassion to the call handler. However, we at Panasonic have decided we need to do even better, and as such we have invested in expanding our Technical helpline team to improve availability and offer even more support.” New Features One of the new features is a video support function, enabled by the technical support call handler, it allows the two parties to see exactly what is being discussed and offers real-time assistance and advice with regards to what is in front of the installer, and not what the call handler imagines is happening. This can help to remotely diagnose issues, ensure real-time knowledge sharing, and significantly speed up repair rates. In this way, highly skilled engineers’ time can be focused on providing world-class technical support, quickly and when it is most needed.

In a grassroots campaign, Rick Hasselbeck, Chief Commercial Officer of GE Appliances (GEA), a Haier company, took to the streets sharing gifts with hungry consumers. To the surprise and confusion of GEA owners, the personally hand-delivered parcels were empty but hot. One anonymous fan said, “I was delighted to receive a package from the company’s CCO and thought I must have won something. Instead, I was left scratching my head.” Delivering dozens of packages to registered customers, Hasselbeck reportedly had a skip in his step as he served up the heated gifts. “I intended for this to be an easy task, and it’s really no heavy lifting,” said Hasselbeck. Airdropped Surprises Known for long-winded speeches and sleepy Zoom meetings that drone on… and on…, Hasselbeck held a lengthy press briefing earlier in the day with extensive detail on the preparation of fried foods. “He kept saying things like, ‘crunch without the calories’ and ‘crispy for a crowd’, but to me the speech was full of hot air,” said one prominent, national correspondent in attendance. “Although that brussels sprouts recipe was a keeper,” he added as a sidenote. Because Hasselbeck could only cover so much ground in one day, some consumers received their free gifts as airdropped surprises. Drones took to the skies, sweeping the nation on the first of April to deliver #AirFryApril as over-the-air (OTA) upgrades. How It Works More than 200,000 consumers who purchased GE Appliances’ ranges with WiFi capabilities in the last four years can now have No-Preheat Air Fry via an over-the-air upgrade through the GEA SmartHQ app. To access state-of-the-art air fry technology, connect one of the 60 eligible models of CAFÉ, GE Profile, and Haier appliances first. Then, users will be notified through the SmartHQ app and should follow the prompts to complete the upgrade. See instructions here: “We are ‘Better When Connected’ and now your oven is getting better too, with smarter cooking,” said Hasselbeck. “We invite you to join the owners adding air fry technology to the ovens already in their homes. That’s the benefit of smart appliances. Ask yourself, fry, not?”
Carrier is proud to support Habitat for Humanity International’s Home is the Key campaign, aimed at unlocking more families’ futures with homeownership – a fundamental stepping stone to better health, more financial freedom, and security. The company has begun its fundraising effort with an initial $250,000 donation to the campaign and will continue to raise awareness throughout the month of April by engaging its distributor and dealer network and employees through advertising, social media, and digital outreach efforts. Launched in 2017, Home is the Key is one of Habitat for Humanity’s signature fundraising and awareness campaigns, taking place annually in April. With support from Carrier, as well as funds raised through Home is the Key, more families can partner with Habitat to secure the strong foundations a safe, decent, and affordable home provides. Supporting The Campaign “Habitat for Humanity is an organization that is very dear to us at Carrier, and we have been fortunate enough to be able to support its efforts for the last several decades,” said Justin Keppy, President, NA Residential & Light Commercial, Carrier. “The Home is the Key campaign is designed to inspire individuals and businesses to donate to Habitat for Humanity during the month of April to help more families build a decent, affordable place to call home. In addition to the many fundraising and awareness efforts we have planned, we are engaging our employees and distributor and dealer networks to support this campaign.” Donations Carrier has supported Habitat for Humanity International as a Gold Level Sponsor Along with its support of Home is the Key, Carrier employees have helped build one Habitat home a year in Indianapolis since 1998, and the company has donated an HVAC system to every Habitat home built in the city since 1995. In addition, Carrier has supported Habitat for Humanity International as a Gold Level Sponsor at the 2018 and 2019 Jimmy & Rosalynn Carter Work Project, and during the aftermath of Hurricane Harvey, Carrier donated 100 ductless units to assist in the re-build. Carrier has provided financial support, product donations including from Carrier’s Healthy Homes suite of indoor air quality solutions, and countless employee volunteer hours to local Habitat organizations. Grateful For The Contribution “We’re proud to have the support of companies like Carrier as we look to continuously help homeowners create stronger and healthier lives for themselves and their families,” said Julie Laird Davis, Vice President of Corporate and Cause Marketing Partnerships at Habitat for Humanity International. “Habitat has built a strong relationship with Carrier over the last several decades and we’re grateful for the contributions they’ve made to our efforts. We are looking forward to making an impact together again during this year’s Home is the Key initiative.”
In what can only be described as a very turbulent year, many businesses have had to shut their doors and have all but forgotten about the general upkeep of their sites. With priorities shifted to keeping companies afloat and staff employed, maintenance and servicing has taken a backseat, and many systems will be deteriorating unnoticed. It goes without saying that one of the first tasks that employers will have to tackle when returning to work is a deep clean. As we are still in the throes of a pandemic, a clean and disinfected workplace is the number one priority that needs to be ensured, before any staff can be welcomed back to work. This should be closely followed by maintenance of the site’s equipment. Importance of regular HVAC maintenance Regular HVAC maintenance is extremely important as it keeps systems performing efficiently and effectively Regular HVAC maintenance is extremely important as it keeps systems performing efficiently and effectively. The nature of HVAC maintenance does change depending on the time of year, and with some sites being shut for months and through different seasons, managers will need to review their current equipment to ensure it is compliant and working correctly as soon as possible as signs of normality start returning and facilities begin to reopen. While warehouses and factories may have still been operating in some capacity over the last 12 months, many office buildings have seen little to no employees for more than a year in some cases, therefore, risking deterioration and even damage to their systems going unnoticed and untreated. But with so many pieces of equipment at each site, it is often hard to know where to start and what to prioritize. Following HVAC manufacturer’s recommendations In order for businesses to keep functioning as best as they can and to avoid any more disruption, those in charge of maintenance and servicing need to be educated on how the conditions of a system affects the type of work it needs. Manufacturer’s recommendations should also be taken into account. To help define what these are and how to approach them, mechanical and electrical engineers recommend: The coils and pipes in HVAC equipment that are responsible for heat transfer are checked regularly, because if the equipment gets dirty, it won’t transfer heat and energy as well. Checking controls annually to ensure that the HVAC system is running properly, as control calibration can alter. By scheduling regular check-ups, accurate operation is maintained. Maintaining equipment with fans quarterly to maximize longevity. Three key areas include monitoring the impellers, belts and bearings for any dirt, wear and tear, friction or erosion. Keeping an eye on filters, as when they are clogged, it increases the pressure drop in a system, which makes fans work harder to maintain the same airflow. A quarterly clean is usually sufficient for most filters. This is also true of strainers in systems. Optimizing HVAC and electrical equipment With spring now upon us, businesses need to optimize their HVAC and electrical equipment for maximum efficiency With spring now upon us, businesses need to optimize their HVAC and electrical equipment for maximum efficiency. This includes reviewing the sequence of operations for a morning warm up and cool down. However, it’s important to remember that because of prolonged closures over the last 12 months, autumn and winter checks, and in some cases, even summer checks were not able to be carried out in 2020, so before the spring work begins, backdating the maintenance is a good place to start. Ensuring buildings’ energy efficiency With the help of experts, HVAC maintenance doesn’t have to be time-consuming and overwhelming, but it’s a critical part of maintaining an energy-efficient building that is both comfortable and reliable. With regular servicing and some basic knowledge of what is required, sites can maintain optimum efficiency all year round. Noise complaints can also be an issue, if HVAC maintenance isn’t carried out regularly. Spring is a good time for businesses to perform services on their equipment, prior to the summer months starting and should be used to ensure that condenser coils and air handler filters are both clean. The dirtier the equipment, the noisier and less efficient it becomes, which is bad news for any business. Preparing buildings for staff returning to work When a building is returning to normal occupancy after a lengthy closure, additional checks must be considered before reopening is discussed. When a building is initially mothballed, it must be prepared for long term vacancy, but many businesses will not have had this opportunity before the national lockdown, which basically entails that these checks will not have been carried out. After a building becomes unoccupied, it is not the case that maintenance activity should also stop After a building becomes unoccupied, it is not the case that maintenance activity should also stop. At the very least, the frequency of existing planned maintenance will change, but in some cases, more maintenance tasks are required in order to keep the site ticking over. This includes flushing of water systems, Legionella testing and insurance inspections to keep the property functional and compliant. Countering health and safety issues As the COVID-19 lockdown restrictions are lifted across the United Kingdom and many businesses are gradually reopening, it will present health and safety problems that have not been faced before and will very likely see a surge in services and maintenance being required. With this in mind, it is vital that maintenance becomes a priority as normal service is resumed to not only ensure efficiency, but also to make sure that no employee or visitor to a site is put in danger. Emerging from a surreal 12 months, there is no doubt that companies will still face challenges, so it is crucial that avoidable maintenance problems do not become one of them, so don’t delay in booking routine checks.
As part of the UK Government’s stated commitment to net-zero carbon emissions by 2050, gas boilers, along with other fossil-fuel burning boilers, are to be banned in newbuild homes from 2025 under the Future Homes Standard. Although the ban has received a widespread welcome in principle, there has been criticism. Environmental groups have criticized the ban for not going far enough in tacking the escalating climate crisis, and the construction and home-building industries have criticized it for the challenges it brings in achieving a viable home-heating alternative in such a short space of time. Placing significant demand Despite the criticism, the ban doesn’t go far enough; applying to newbuild homes only, with, as yet, no plans to phase out gas heating in existing homes. New heating technology has to be ready to roll out before 2025, whether it’s to 160,000 homes per year (the annual approximate figure of new homes built) or the UK’s entire housing stock of 29 million. Despite the criticism, the ban doesn’t go far enough; applying to newbuild homes only The Home Builders Federation, in reaction to the Future Homes Standard, has said, “It’s going to be a challenge and a huge area of work.” And it is widely acknowledged there is significant demand placed on the building and HVAC industries to produce a long-term, viable solution. Challenges include the creation of new, cost-effective designs of energy infrastructures, and implementation in time for the short deadline of less than four years away. Gas boiler heating systems From energy design engineers to developers, suppliers, and energy companies, everyone in the supply chain is affected in delivering a solution that UK homeowners can afford and that developers can supply. The communications challenge also cannot be underestimated, to bring along the public to the reality that homes cannot, ultimately, continue to be heated by the gas boilers they are so familiar with. The most likely low-carbon alternative to gas boiler heating systems is generally acknowledged to be heat pumps and heat networks, powered by renewables. It has been estimated by the Committee on Climate Change that by 2030 there will be 2.5 million heat pumps in new homes. Heat pumps offer comparable heating power to gas boilers and are powered by low-carbon electricity. Heat pumps have great potential for saving carbon; approximately 25-85 tCO2 per home over an average lifetime, reducing carbon emissions by 90%. Existing gas system But hydrogen is expensive to produce and although the existing gas system could be readily used for supply But for heat pumps to provide the level of warmth, particular in winter, and summer, weather in the UK, their effectiveness relies on excellent insulation, including triple glazing and adaptations to walls, floors, and ceilings. And while there has been a drive to get our draughty homes better insulated in the UK in recent years, with various grants and funding, this will be particularly crucial for newbuilds going forward. Hydrogen boilers could be an alternative to gas boilers. Hydrogen produces no emissions when burnt, only water and heat. But hydrogen is expensive to produce and although the existing gas system could be readily used for supply, and by consumers already familiar with a boiler system, it is not yet seen as a full solution to the replacement of gas. Technically qualified workers Trials are due to be carried out in the north-east with hydrogen-ready boilers. But the impending deadline and challenge for production and systems to be ready and tested, for mass implementation is unrealistic. Even before the Future Homes Standard was announced, there was an acknowledged shortage of skills. Engineering UK, in a recent survey, found that an additional 1.8 million engineers and technically qualified workers would be needed by 2025 in order to meet demand. But the impending deadline and challenge for production and systems to be ready and tested Nearly a third of HVAC firms have declared a skills shortage, with many feeling there is a crisis in the sector of sufficient qualified workers who can satisfy the new regulations. Now the demand is set to rise with the ban, as well as Brexit. A large proportion of qualified HVAC workers are sourced from the EU, further compounding the crisis of the skills shortage already faced. Zero-Carbon technologies From imagining life without a gas boiler to a young person seeing their future career in engineering and renewable energy, effective communications and campaigns could go a long way. Targeted lifestyle campaigns, with positive, compelling case studies of homes of the future being powered by green, zero-carbon technologies could help to drive the momentum for innovation from a domestic base. Talent strategies could also combat the reality of an ageing and diminishing workforce in HVAC and other sectors. It’s vital now, more than ever, that young people see a career in renewable and eco-living technology as, not only rewarding but futuristic, global, and sophisticated. Any alternative to gas heating has to be affordable for UK households, and therefore for housing developers to adopt. Fuel poverty is a real risk. Energy-Saving measures The right help needs to be in place to support the development and take-up of the alternative According to the Committee on Climate Change, it costs £4,800 to install low-carbon heating in a new home, but £26,300 in an existing house while there are various funding initiatives for households adopting energy-saving measures, the right help needs to be in place to support the development and take-up of the alternative. Not just for newbuild homeowners, but beyond 2025 when existing households are called upon to switch. The Home Builders Federation have said of the Future Homes Standard, “Ambitious deadlines pose enormous challenges for all parties involved including developers, suppliers, energy companies in terms of skills, design, energy infrastructure and the supply chain.” Low-Carbon heating technology But there is also a stated dedication to achieving what can be realistically achieved, proving that there is a genuine commitment to ensuring our brighter, cleaner future and planet with low-carbon heating technology. The ultimate challenge now will be in Government, agencies, and industry working together, in a dedicated way, to be realistic about, and tackle the challenges across the board so the right solution for our home-heating future can be achieved, in time, and ready for a rollout for the new homes we build from 2025.
With the roadmap laid out for the government to guide us out of lockdown, the end of the pandemic seems as though it could be in sight. However, HVAC units remain outdated in hotels, hospitals, schools, and offices and there is a worry that COVID-19 can still spread quickly and easily through air vents, mitigating the effects of lockdowns and vaccinations. Dr. Rhys Thomas, Chief Scientific Officer at infection mitigation specialist PP-L and a frontline NHS doctor, says that the government’s neglect of using HVAC solutions to reduce transmission is a major oversight. Airborne transmission indoors By failing to follow the lead of other nations that are now recognizing the importance of ventilation in relation to the airborne nature of the virus, the UK’s approach hasn’t been as comprehensive or as forceful as it could be, with quietly introduced, piecemeal changes to regulations being too little, too late. At the moment, some governments don’t want to come out and admit that COVID-19 is an airborne hazard and that their failure to recognize it as such has led to higher infection and mortality rates and suffered even greater impacts from new variants. Research shows that 80% of the spread of the virus is through airborne transmission indoors– the inhalation of infected droplets that are moving around in the room’s air currents or ventilation systems– which a two-meter distance or the opening of the window is unlikely to combat. New quarantine hotels The UK was geared up for an influenza-like pandemic rather than an airborne one The airborne nature of COVID-19 is what has caught governments off guard and meant we are still playing catch-up while new variants are starting to appear, which was also always to be expected. In terms of preparedness, the UK was geared up for an influenza-like pandemic rather than an airborne one, such as the challenge posed by a SARS coronavirus. As with all airborne illnesses, the greatest risk of transmission is indoors and in confined spaces such as public transport, office buildings, factories, and even potentially the new quarantine hotels which are being introduced to prevent the spread of the virus. The governments ‘hands, face, space’ messaging cover the opening of windows to help with airflow, but the reality is much more complex. Latest SARS Coronavirus The risk of infection indoors is vastly higher than outside, and current advice simply isn’t enough. There’s a perception – even in hospitals – that fresh air is clean air. I’ve been shocked to see hospitals that I’ve visited assuming that simply opening a window is enough. That is simply not the case – the air needs to be disinfected by ultraviolet light for it to be clean enough to prevent the spread of coronaviruses. I saw this in practice in the first SARS pandemic in 2003, where UV was used and proved incredibly effective in South East Asian hospitals once again against the latest SARS Coronavirus that causes COVID-19. The spread of the virus around the Diamond Princess cruise ship, which hit global headlines in January 2020 when more than 700 passengers and crew tested positive for COVID-19, has become a case-in-point for the theory behind the airborne transmission. Killing airborne contaminants Part F of the Building Regulations on ventilation has been updated and is out to consultation Researchers from Harvard and the Illinois Institute of Technology developed a computer model of the cruise ship outbreak, which found that the virus spread most readily in microscopic droplets light enough to linger in the air. The research added to the pressure already being placed on the World Health Organization to recognize the airborne dangers of the virus, including an open letter signed by more than 200 experts. The key point here is that there has been some level of recognition from various government departments that the virus is airborne, and they have mitigated accordingly. Part F of the Building Regulations on ventilation has been updated and is out to consultation, and the Health and Safety Executive’s COVID-Secure Guidance for the Workplace on Ventilation has also been quietly updated in recent weeks to recommend the use of ultraviolet air filtration systems, which are proven to kill airborne contaminants. Key communication issue These UK regulations are now, at last, starting to get more aligned to other global institutions’ recommendations such at the renowned Centers for Disease Control and Prevention (CDC) who support the importance of ventilation and UV devices to significantly reduce infection risk. This is a positive step, but the key communication issue is that if the government don’t fully endorse and be more vocal about the airborne threat of COVID-19, and regulatory changes being made, then neither will the wider public. This is a huge issue because the government is already preparing for this virus to be around in some form for many years to come. With 40 million doses of vaccine set to arrive in 2022 and an overall supply line that is set to last until 2025, it’s clear that there is an acknowledgment that this will be a long fight. The SAGE scientists like Professor Chris Whitty and Sir Patrick Vallance are also referring to this virus as endemic now. Long-Term readiness The government is already building long-term readiness and diluting the risks by using different suppliers With 407 million doses of vaccine on order, the government is already building long-term readiness and diluting the risks by using different suppliers, but without the acknowledgment of the airborne risks, this can only do so much – it needs to be a joined-up, blended approach. Prevention is better than the alternative because in this case, there is unlikely to be a cure for a virus that spreads and mutates at the rate this one does. Trying to keep ahead of this virus is a dangerous game. It is incredibly adaptable and there is an awful lot of guesswork about predicting the spread and virulence of new and more easily spread strains. Ongoing lockdowns are simply not an option and are increasingly ineffective as people struggle with the monotony and isolation they bring. We need to get on the front foot and not only rely purely on medicine to help solve this crisis. Air filtration systems Engineered solutions like UV-C (also known as UVGI) and air filtration systems are needed wherever possible to help cut this virus at the knees and stop transmission in the first instance. These solutions are now being brought in by several industries and many countries around the world are specifically recommending them because they are recognizing that the guidelines in their current form aren’t doing enough. Those industries such as food manufacturing and production that rely on having people on the ground and in their factories are having to look beyond what they are advised and finding solutions that actually do work. Hospitals, schools, and hotels are the next places that need to be looking at this kind of response, especially with the government’s travel regulations meaning that potentially infected travelers are being kept in potentially inadequately ventilated spaces that could actually accelerate contagion spread to other travelers or staff. Action needs to be taken now, or we risk the further unnecessary spread of this dangerous pathogen.
Innovation is a driving force behind most industries, including HVAC. Keeping up with industry research, and looking toward the future, helps HVAC professionals to anticipate upcoming changes to the industry, and to be prepared when they happen. There is no shortage of innovation in the sphere of HVAC. I recently came across some interesting designs (and one product already on the market!) that provide a useful glimpse into the types of projects that may shape the HVAC industry of tomorrow. Large-Scale Air Purification System A new purification system on the horizon provides higher levels of purification and sanitation for large-scale applications such as hotels and other big businesses. It also seeks to protect HVAC service employees from exposure to viruses when they service a system. Rather than filter out viruses, the system destroys them with photocatalysis, which uses a semi-conductor to create radicals to zap the viruses. Photocatalysis has been around for decades but is only now becoming refined enough to provide a marketable solution. Promethium, the company seeking to bring the filtration to market, evolved from the work of two the University of Nevada, Las Vegas (UNLV) students, and a University of California (UC) Berkeley graduate. The technology can be used in several ways – from water purification to energy generation – but purifying air is the first priority. Each unit is customized for a specific application, but a “basic” standard unit starts at around $10,000 and can clean 40,000 square feet of space, enough for a casino gaming floor, for example. The project won $250,000 in a contest sponsored by UNLV’s Lee Business School and has also signed a research agreement with Purdue University. It should be ready to go to market this year. Dual-Mode Heating and Cooling Device Duke University is demonstrating the heating and cooling capabilities of nanomaterials, including a dual-mode heating and cooling device that could lower HVAC energy costs by nearly 20% in the United States if widely deployed. The invention combines mechanics and materials science to either harness or expels certain wavelengths of light. Depending on conditions, rollers move a nanomaterial sheet back and forth to expose either heat-trapping materials on one half or cooling materials on the other. Designed at the nanoscale, one material absorbs the sun’s energy and traps existing heat, while the other reflects light and allows heat to escape. Flair’s Smart Vents are DIY devices that fit into existing floor and wall register slots in standard sizes The cooling portion of the sheet has ultra-thin silver film covered by an even thinner layer of clear silicon. Together, they reflect the sun’s rays like a mirror. The unique properties of the materials also convert energy into mid-range infrared light, which does not interact with the gasses in the Earth’s atmosphere and easily passes into space after it is emitted. For heating, an ultra-thin layer of copper is topped by a layer of zinc-copper nanoparticles, which interact with the copper beneath them to trap light onto the surface, thus absorbing more than 93% of the sunlight’s heat. The “reversible thermal contact” allows users to switch between two modes of heating or cooling. The device would be especially useful in the world’s temperate climate zones that require both heating and cooling during the year – and sometimes requires both within a single 24-hour period. Do-It-Yourself Smart Vents Flair’s Smart Vents are do-it-yourself (DIY) devices that fit into existing floor and wall register slots in standard sizes. The vents control airflow across individual rooms to boost efficiency. Electronics for the low-profile devices are contained in a casing that rests under the floor level. They can be hard-wired for power or can use two C batteries. The Smart Vents work with smart thermostats and/or with Flair’s Puck cylindrical devices that include temperature control and monitoring. The Smart Vents coordinate their open/shut status depending on temperature needs. For example, the vents can be used to equalize the temperature and route heating and cooling intelligently. It can provide a solution if one room is too cold when cooling or too hot when heating. The approach is aimed at approximating the results of zoned HVAC systems at much lower costs and to replace existing wall ducts.
The cruise ship industry has cracked the code on keeping passengers and crew safe from the coronavirus (COVID-19) spread, including changes to on-board HVAC systems to use more outside air and to filter out particles as small as the novel coronavirus. The industry, which voluntarily suspended worldwide operations at the beginning of the COVID-19 pandemic, under the guidance of international and national health authorities, plans to resume worldwide operations fully later in 2021. Health protocols to mitigate COVID-19 risk The cruise ship industry resumed sailing in parts of Europe, Asia and South Pacific in July 2020 The cruise ship industry resumed sailing in parts of Europe, Asia and South Pacific in July 2020 and completed more than 200 sailings by the end of 2020. The success of these early sailings demonstrated the effectiveness of new protocols to mitigate risk of COVID-19 among passengers, crews and at destinations. The industry will resume operation in the United States, Canada, Mexico, the Caribbean and elsewhere in 2021. Cruise operators, such as Royal Caribbean, have implemented new HVAC systems as part of the protocols. Supplying 100% fresh and filtered air Royal Caribbean says its HVAC system now continuously supplies 100% fresh and filtered air from outdoors to all indoor spaces. There is a total air change up to 12 times an hour in staterooms and about 15 changes per hour in large public spaces. Fan coil units provide an extra layer of protection in local spaces, such as public venues and staterooms, continuously scrubbing the air of pathogens and using MERV 13 filters to capture aerosols between 1.0 and 3.0 microns with 90% efficacy. Bio-aerosol assessment study Royal Caribbean participated in a bio-aerosol assessment of its ‘Oasis of the Seas’ ship by the University of Nebraska Medical Center. The study involved releasing billions of 1-micron aerosol-sized microspheres, each containing a uniquely DNA-barcoded inert virus surrogate, at pre-selected spaces throughout the ship. The test was intended to determine the efficiency and effectiveness of the vessel’s indoor air management strategies and to understand spread of aerosols through the HVAC system. Low risk of cross-contamination of air Testing results led to minimal changes, such as ensuring air exchanges are close to hospital standards and using MERV 13 filters Over a week aboard the Oasis of the Seas, scientists released billions of the individually tagged microspheres and then tracked where they went and how long they lingered in the air, and on surfaces. Testing results led to minimal changes, such as ensuring air exchanges are close to hospital standards and using MERV 13 filters. The study confirmed that cross-contamination of air between adjacent public spaces is extremely low and undetectable in most test cases. Royal Caribbean’s Healthy Sail Center determined seven important elements the cruise line can do to manage indoor air and keep it clean. These elements include: Enhanced filtration to the highest level possible Optimize airflow patterns Use negative pressurization in isolation rooms Minimize unfiltered, re-circulated air Increase number of air changes per hour Use portable HEPA filters in congregate areas Maximize outdoor functions and physical distancing Facilitating return to operation of cruise ships At the start of the COVID-19 pandemic, between March 1 and July 10, 2020, the Centers for Disease Control and Prevention (CDC) discovered nearly 3,000 cases of COVID -19 or suspected COVID-19 infections and 34 deaths across 123 cruise ships. In October 2020, the CDC lifted its no-sail order, laying out guidelines for big-ship cruising to resume operations in U.S. waters. The Cruise Lines International Association (CIA), which represents 95% of the cruise ship industry, has said its members will return when the time is right and that timing will be based on factors, including input from scientists and medical experts. Cruise companies also have new technologies available to them now. For example, the Italian company, Integra provides an air sanitizer that uses an odorless disinfectant to combat airborne illnesses. It can be installed in 15 minutes.
The connectivity of the Internet of Things (IoT) provides new tools to monitor the well-being of an HVAC system, to provide instant alerts to any operational problems and even to predict when problems are likely to occur. Being alert to early warning signs of a problem enables deployment of less-expensive fixes before the problem escalates. predictive analytics Remote monitoring and predictive analytics of HVAC systems have been even more valuable during the time of the COVID-19 pandemic, when many buildings have been empty. Potential problems come to light faster and can be repaired less expensively, even if no one is on site to complain about an obvious failure. When buildings are occupied, the customer experience is even better and operational and maintenance costs are lower. These capabilities can be integrated with other Building Management Systems (BMS) to provide a broad-based view of various operating systems throughout a facility. In addition to early warning of system failure, system monitoring can also provide new and smarter tools for keeping track of indoor air quality (IAQ) and to minimize energy consumption. Artificial Intelligence (AI) in the Cloud Predictive and preventive maintenance are key to ensuring that issues are addressed before they can do damage Sensors and other devices deployed in today’s systems provide hundreds of new data points that are interpreted by Artificial Intelligence (AI) operating in the Cloud. The combination provides detailed and useful insights into how a system operates over time, thus maximizing operation and minimizing energy usage in ways that are more in tune with environmental needs than ever before. Predictive and preventive maintenance are key to ensuring that issues are addressed before they can do serious damage, according to Johnson Controls (JCI). Smart data analysis enables more informed and smarter decisions, thus resulting in reduced maintenance costs, improved efficiency, and overall peace of mind, as per the company. Connected Services Johnson Controls (JCI) offers Connected Services to provide customers with constant equipment monitoring and data analysis, and uses the data proactively to identify faults before they occur and even predict future optimization opportunities and efficiencies. Integration of both equipment and software into a single system makes it more than a sum of its parts. Johnson Controls lists some key benefits of implementing an integrated system: Identify energy savings opportunities. Regular reports on the operational performance provide insights on areas of improvement. Extend asset life. Identifying and managing required maintenance helps to extend equipment lifespan. Minimize repair costs. Faults mitigated at an early stage avoid major failures. Reduced emissions. Operational performance reporting enables chillers to operate in the most efficient range. Monitoring system performance Emerson’s Sensi Predict line goes to the root of HVAC systems to monitor performance, identify issues and alert contractors and home owners to the efficiency, energy usage and overall performance of HVAC units. An internal Emerson study reviewed the most common HVAC failures and determined that installing the technology could detect up to 80% of failures in these areas, before a home owner suffers system outage. Real-time and connected systems use a variety of sensors that constantly monitor the functioning of an HVAC system. Connectivity puts more information than ever at the fingertips of HVAC professionals, making them more responsive than ever to customer needs.

Hawkes Place is a property like no other. Situated in Sevenoaks, Kent, one homeowner has created a truly unique building where every room is connected through home automation devices. Designed and built by Tony Gotts as a personal project, the three-bedroom, one-storey property was the first smart home he had built. The unique design sees each room completely curved, with no square corners in sight. With the entire house automated, including audio, lighting, heating, blinds, and front door access, the property has been built to a high standard to create a truly remarkable home. Controlled entrance system To support the installation, Mr. Gotts called upon the experience of the electrical contractor, Luke Kavanagh of Lake Home, who suggested one single supplier cover all of the home’s automation needs. To transform his property into a smart home, the owner wanted to connect the heating, lighting, blinds, and audio, while also incorporating a controlled entrance system. In addition, each room of the house required its own touch screen control system. Hawkes Place was the first property with which the owner had utilized home automation systems to this extent, and therefore an easy-to-use all-encompassing system was required. Door entry system Every room in the property had at least one element of smart technology installed Electrical contractor, Luke Kavanagh, recommended Legrand’s User Interface range, including its MyHOME Up system, coupled with its Bticino door entry and Nuvo audio systems. “As soon as I understood the brief, I immediately recommended the Legrand suite of smart home products,” Luke comments. “I contacted Chris Janes at Legrand, who drove out to Kent to discuss the different options with the homeowner in person. This was really useful as it enabled the owner to see exactly what was possible for the size of the property.” Every room in the property had at least one element of smart technology installed. Throughout the house, the heating, lights – both inside and outdoor – and blinds are all controlled by the MyHOME Up system, providing the end-user with full control at all times. The accessibility of the house was also enhanced, thanks to the use of a Bticino door entry system. Audio distribution system Additionally, the Legrand Nuvo multi-zone audio distribution system was installed throughout the property. Allowing audio to be managed and controlled in numerous rooms, users can connect music and audio streaming services and play in all areas of the home. For this project, one major advantage is the ability to bring together control of door access, as well as the lighting, heating, and blinds, on mobile phone apps. In addition to this, 7-inch touch screen panels were installed into every room, allowing complete control. For the installer, Legrand’s MyHOME Up system served two key benefits: its ease of installation and the functionality for the end-user. Once connected to the BUS system and the app is installed, the devices will set-up automatically. Intense training courses The app allows the installer to easily access multiple devices when starting up the system Luke comments: “Coming from an electrical background, the simplicity of Legrand’s systems means we are able to support project managers transform properties into smart homes. I don’t have expertise in IT, and I find that other similar systems require technical knowledge in order to complete the installation, which often includes expensive and intense training courses.” One of the key benefits of a MyHOME Up installation is that the innovative app supports the connection of all devices and is easy to control for both the installer and end-user. The app allows the installer to easily access multiple devices when starting up the system, thanks to the self-learning procedure, while the user can then manage their home automation scenes at any time. Confidently creating scenes Luke continues: “The whole installation process was very easy, not just from my point of view but the end user’s as well. The customer has gone from being a smart home novice to confidently creating scenes which improve day-to-day living habits. Since the installation was completed, we have already successfully recommended the system on another three projects.” In addition to installation and account support, Legrand also offers free training courses. The MyHOME Up range can be installed after just one day’s training, and installer Luke Kavanagh utilized this free service before installing the system. Luke adds: “I had previously undertaken a number of Legrand’s training sessions, including a session in Belgium, as well as for MyHOME Up. It is a really good program, and makes the system incredibly easy to install for anyone in the profession.” Creating smart scenes YouGov’s Smart Homes 2018 Report indicated that almost one-quarter of Britons own one or more smart home devices The course explains the role of smart devices in the home, and shows how creating smart scenes and actions can help end-users decrease their energy usage and waste. Free to attend, the training program is ideal for contractors and system integrators and takes place at Legrand’s state-of-the-art training center in Birmingham. Home automation is not new. In fact, YouGov’s Smart Homes 2018 Report indicated that almost one-quarter of Britons own one or more smart home devices, excluding smart meters, while one in ten have two or more. High customer satisfaction While adoption is becoming more common, electrical installers and contractors are tasked with the challenge of understanding this often-complex technology, to enable them to enhance their services to customers. Taking advantage of training from manufacturers, like Legrand, can make the installation much easier, while also providing high customer satisfaction. Luke Kavanagh concludes: “This project is an excellent example of how a simple, slick and extremely efficient home automation system can be installed. The Legrand products are very easy to install and the customers are always left smiling, testing new combinations each day. While not all systems are the same, I would recommend taking advantage of any available training because it not only equips you with the ability to install effortlessly, but it also provides the knowledge to answer any customer questions.”
It would be great if there was always a clear-cut sign to show that one needs something like furnace repair in Loveland, CO, wouldn’t it? Well, there actually are quite a few such signs, but they may not be quite as clear as one would like. The clearest need for furnace repair would probably be a completely broken down furnace, right? Well, sure—but obviously one doesn’t want to wait for the furnace to break down entirely before they have it repaired! That’s where the tips are going to come in handy. And the “good” news is that these are problems that one is already aware of. One may not realize that they alone are enough to justify system repairs or, at the very least, a call to have the system evaluated. Therefore, keep the system functioning properly and safely by scheduling prompt furnace repairs the moment that one has cause to suspect there is a problem. Unheated Furnace Air The air coming from the furnace doesn’t seem hot enough. Oh well, it’s pretty cold out. The house will heat up eventually, even if it takes a little longer than usual. One should stop making excuses for problems like this. Regardless of how cold it may be outside, the furnace should be capable of heating the air in the home effectively. If it doesn’t seem like the air is hot enough, there could be quite a few problems at play. It’s possible, for instance, that one has leaky ducts that are pulling unheated air from unheated areas of the house (like between walls) into the system. One could also have a problem with the thermostat or with fuel delivery/combustion mechanisms. Furnace Running in Short Cycles A very dirty filter can actually create so much airflow resistance that the system winds up overheating It is called short cycling because a heater is not supposed to run in short cycles. Short cycling is a problem. One wants a heater to run in full, even cycles. So if one notices short cycling in their home, one may need repairs. There is one situation that one should rule out before scheduling repairs. That is a dirty air filter. A very dirty filter can actually create so much airflow resistance that the system winds up overheating, causing it to shut down to avoid damages. Then it starts up again, only to cycle back down before long. If the filter isn’t dirty, then one is likely to have a problem that is going to require professional service. Increasing Energy Bills There is very little that is truly “free” in this life, and heating a home is no exception. One has to pay for comfort. That doesn’t mean that one should accept overpaying for comfort, though. If the energy bills are too high, it could definitely be a result of a compromised system in need of repair.
After a successful trial of two seed vehicles, Petit Forestier has supplied 123 new rigid trucks into a major logistics customer, all featuring Carrier Transicold SYBERIA MT (multi-temperature) systems. The largest UK order to-date for Carrier Transicold’s powerful engineless truck refrigeration technology, the new vehicles will help to improve sustainability across the customer’s fleet. Carrier Transicold is a part of Carrier Global Corporation, the pioneering global provider of healthy, safe and sustainable building and cold chain solutions. Supplied by Petit Forestier on full-service contract hire, the new assets include a mix of 15, 18 and 26-tonne DAF trucks and will make food and beverage deliveries to well-known high street coffee shops and a national chain of hotels. The vehicles feature specialist bodywork from Solomon Commercials, with chilled and frozen compartments that incorporate a moving interior spine to allow both cages and pallets to be transported. In addition, as the SYBERIA unit is mounted above the cab and has no need for a separate fuel tank, space is freed on the chassis to store and carry waste intended for recycling. Carrier’s engineless technology The SYBERIA system runs on power derived directly from the truck’s ultra-clean Euro VI diesel engine “We’ve worked closely with Carrier and our customer to ensure every aspect of the build helps them improve the sustainability of the fleet,” said Helder Ribeiro, Managing Director, Petit Forestier. “Having performed impeccably on two trial vehicles, Carrier’s engineless technology plays an integral role in this process. With no need to run an auxiliary diesel engine, we can deliver a significant cut in emissions, without sacrificing performance.” The vehicles delivering to coffee shops feature twin compartments for transporting chilled and frozen food to a chain of 2,500 outlets. Those operating on the hotel contract benefit from triple compartments for delivering frozen, chilled and ambient products. All the trucks will operate on high-intensity, multi-drop delivery routes, making powerful, reliable refrigeration unit performance imperative. The SYBERIA system runs on power derived directly from the truck’s ultra-clean Euro VI diesel engine, thanks to Carrier Transicold’s ECO-DRIVE power module. The system uses a hydraulic pump connected to the truck engine’s power take-off, driving a generator capable of delivering electrical power to the unit that can provide 100% refrigeration capacity, even at standard idle speed. SYBERIA system This project was designed to showcase our customer’s commitment to sustainability and the environment" Each ECO-DRIVE unit is fully integrated into the SYBERIA system above the cab, leaving more space on the chassis to house the truck’s recycling lockers. The SYBERIA system also boasts rapid temperature pull-down capability and operates at a PIEK-compliant level below 60 dB(A) – making it an ideal solution for any intensive urban delivery route. The 123 vehicles replace older assets, after Petit Forestier won a competitive tender to supply the trucks on a seven-year contract hire basis. “The build process has gone seamlessly from start to finish, and that’s down to how closely all involved have worked together,” said Ribeiro. “This project was designed to showcase our customer’s commitment to sustainability and the environment, and Carrier has played a major role in this successful outcome.” The vehicles will operate across the UK, clocking up between 45,000 and 67,000 miles per year. The SYBERIA MT system is one of the solutions offered through Carrier’s Healthy, Safe, Sustainable Cold Chain Program to preserve and protect the supply of food, medicine and vaccines.
A lot of homeowners think that heat pumps are no match for the cold winter nights in Indianapolis and across Central Indiana but that isn’t true. Not only are heat pumps able to stand up to Indiana winters, but heat pumps are also an extremely cost-effective and energy-efficient HVAC solution. If one is interested in changing the heating system to an energy-efficient heat pump, Chapman offers professional heat pump maintenance, repair, and installation services in Indianapolis and the surrounding areas that will improve the overall comfort of the home. Why is a Heat Pump Ideal? There are several reasons why heat pump systems are great for Indianapolis area homes. If any of the following benefits could positively impact the home, one should consider heat pump installations services: energy and Electrical savings Heat pumps use electricity and one can see significant energy savings from operating a heat pump Marion County has one of the lowest electric rates in the country, according to Chapman owner Jeff Chapman. Instead of using fossil fuels to heat homes, heat pumps use electricity to move heat from the outdoors and into the Indianapolis home, according to EnergyStar.gov. Because heat pumps use electricity and the rates are low in the county, one can see significant energy savings from operating a heat pump. According to Chapman, if one puts a pennies worth of electricity into an electric baseboard or portable heater, they will get a pennies worth of heat. But if one uses a pennies worth of electricity to run a compressor and heat pump, they may get 3.5 to 4 cents worth back. cost savings on Installation One may save up to 50 percent on the electrical costs with the installation of a heat pump compared to electric resistance heating systems, including baseboard heaters and furnaces. Although one will spend more on electrical costs compared to a gas furnace, they will save overall on energy bills by not using fossil fuels. Efficient with weather Central Indiana can be cold and snowy in the winter, but not as extreme as its northern neighbors. The average higher temperature during the winter months is in the mid-to-high-30s. Heat pumps operate most efficiently above 40 degrees but are still the most efficient heating source down to 30 degrees Fahrenheit. When temperatures dip to 25 to 30 degrees or lower, it could be a problem. When this happens, one will need the assistance of a secondary heating source to go along with the heat pump. Two popular options include electric heat strips or gas furnaces. However, for the majority of winter, one will be just fine running a cost-effective heat pump. heating and air conditioning Heat pumps also provide air conditioning in the spring and summer due to a built-in reversing valve Unlike traditional HVAC systems, heat pumps also provide air conditioning in the spring and summer due to a built-in reversing valve that reverses the flow of refrigerants in the system. Depending on the season, the heat pump can either produce heating or cooling, whenever needed. Quiet operation Many heating and cooling systems are extremely loud. High-quality heat pumps, though, operate both quietly and efficiently. With the installation of a heat pump, one will be able to heat or cool Indianapolis home more quietly than ever. Safer than gas Gas furnaces offer many advantages to homeowners, but they do come with an inherent safety concern, as there’s always the possibility of a gas leak. Because heat pumps use electricity to run, one wouldn’t have to worry about a gas leak, which makes them a safer option. Financing Options from Chapman The company understands that purchasing new HVAC equipment, like a heat pump, is a significant investment for an Indianapolis home. That’s why they have partnered with Wells Fargo to offer 72 months of special financing on a new Bryant system with approved credit. With a Wells Fargo card, one can buy the system immediately and pay over time. Heat Pump Services If one is interested in learning about the advantages of having a new heat pump installed in Marion County or Central Indiana home, including increased energy-efficiency and quiet operation, they should call the professional HVAC experts at Chapman. If the current heating system breaks down at the worst possible time, the experts at Chapman offer 24/7 emergency services to ensure that if a heat pump replacement, repair, or maintenance services are needed after normal business hours, it’ll be covered. The professional heat pump technicians can help by performing high-quality heat pump maintenance, repair, and installation services to improve the overall comfort of an Indianapolis home.
It’s no secret that the pandemic has had a devastating impact on restaurants, bars, and wineries. With indoor seating restricted in so many places around the country, business owners have had to look for practical and cost-effective solutions to comfortably – and safely – service their customers in an outdoor setting. As the weather turned colder, this became more of a challenge. Two Twisted Posts (TTP) Winery in Purcellville, Virginia, successfully met this challenge by selecting infrared radiant heaters from Marley Engineered Products to warm their outdoor areas. Radiant heater configurations Working with O.T. Hall & Son, Inc., a family-owned electrical manufacturer’s representative firm that has covered the Maryland, D.C., Virginia, and Delaware markets since 1920, Brad Robertson, the owner of TTP, approved the installation of QMark infrared heaters from Marley Engineered Products to heat the outdoor spaces. Ideal for indoor/outdoor, total, or spot heating use, the infrared heaters feature heavy-gauge bright anodized aluminum reflectors and a steel enclosure. “Radiant technology puts warmth right where you need it, without having to heat – or pay for heating – the surrounding air,” said Mike Jennings, inside sales representative with O.T. Hall. “With no need for a fan or exhaust, radiant heaters provide a safe, quiet heating alternative for many indoor and outdoor spaces. We offer a variety of radiant heater configurations, sizes, reflector angles, and elements so that we can customize the right heater for the project and for a customer’s specific performance and design needs.” Forced-Air heaters The radiant heaters from Marley were installed in covered areas including a crush pad with three open sides “Heating the outdoor air with an open flame or forced-air heaters would be less efficient as that heat would just rise up and leave the space through the roof vents,” said Robertson. “Also, we have an all wood barn structure where open flames are not a good option. We sought a low-maintenance, efficient, and easy to control method to keep people seated outdoors comfortable enough to stay and drink our wine.” The radiant heaters from Marley were installed in covered areas including a crush pad with three open sides and on a covered porch along the length of the building. These areas feature 14-foot ceilings with no insulation and are open to the elements. From the original engineering diagram and with the size, spacing, and location of the heaters, the installation was projected to increase the temperature of the large space to within 20 degrees of the outside temperature. Heated covered area In the outside space next to the building, it was projected to increase by 10 degrees. To help deter wind and precipitation, Robertson also installed removable vinyl tent sidewalls around the outdoor spaces. With the heaters fully operational, Robertson placed a thermometer in the area to monitor the temperatures of the spaces. “On one check date, we had a temperature outside of around 32 degrees and a reading in the heated covered area of around 58 degrees,” he said. “Similarly, on a date when the outside temperature was 40 degrees, we had covered area readings of 60 degrees. These readings validate the engineer’s predictive performance and are making our outdoor areas much more comfortable for visitors.” Additional seating areas Robertson expects the added operational cost from the installation of the heaters to be minimal Robertson expects the added operational cost from the installation of the heaters to be minimal and much lower when compared to using propane to heat the same areas. He also believes his revenues should increase slightly because of the additional seating areas. “We were able to turn our patio into an ideal seating area because of these efficient heaters and this kept us open during the COVID pandemic,” said Robertson. “Without these heaters, we would have likely been forced to close for the winter season and not only would have lost revenue but may also have lost long-time employees and customers if we were closed for an extended period.” Now, wine connoisseurs can spend more time comfortably enjoying the high-quality bottles that TTP Winery produces. "We look forward to extending our outdoor season and using our outdoor space for special event groups that we previously had to turn away," added Robertson.
