HVAC Maintenance Vital As Businesses Reopen Post COVID-19
HVAC Maintenance Vital As Businesses Reopen Post COVID-19

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.  

Change Environments Not Behaviors: How Active Air Filtration Can Help the UK Come Out of Lockdown Long-Term
Change Environments Not Behaviors: How Active Air Filtration Can Help the UK Come Out of Lockdown Long-Term

According to the latest statistics, Britain now has the highest daily COVID-19 death rate in the World, following an unfortunate record month of fatalities during January 2021. While UK Government is quick to defend this statistic, the fact remains that our country has been crippled by the SARS-CoV-2 virus, and now, as the population battles through yet another lockdown, it seems that the only 'way out’ is through widespread vaccination. impact of COVID-19 Though imperative, this strategy emphasizes the real challenge that Governments across the globe have faced in trying to control this virus; that reducing the transmission or ‘R rate’ is reliant on the behaviors of people. People who have lived with some form of restrictions for too long, people who are frustrated and tired of the impact COVID-19 has had on their businesses, and people who have simply lost trust in Government U-turns and last-minute decisions. What’s more, despite the best efforts of millions to comply with restrictions, the virus itself is one that is hard to contain, particularly with asymptomatic cases unknowingly passing it to others in key locations like supermarkets or via public transport. Regardless of this challenge, there is a solution that doesn’t rely on changing people’s behaviors, but rather in changing the environment in which people live, work and socialize. That solution is the implementation of Active Air Purification Technology. What Is Active Air Purification Technology? Active air purification technology is effective in every cubic cm of indoor air and surface space simultaneously and continuously Most air purification technologies are passive in that they can only have any effect when the air containing the pollutant comes into close proximity or passes through the unit. Examples of this are filtration, UV-C, and various PCO and ionization technologies. In other words, certain operational conditions must be met in order for them to be effective. Active air purification technology is not limited in this way and is effective in every cubic cm of indoor air and surface space simultaneously and continuously. This means pollutants, like viruses and bacteria, are instantly treated no matter where or when in the indoor space they are emitted or exposed which is significant in the context of COVID transmission. Whether required to mitigate microbials, allergens, or dangerous gases and VOCs, active technology offers a unique solution to destroying microbials instantly, offering a safer, cleaner, and more effective approach to air purification in domestic, commercial, and industrial environments. REME Air Purification Technology REME is an active air purification technology developed and patented 15 years ago by RGF Environmental Group, a COVID critical environmental innovator and manufacturer headquartered in the United States. Using no chemicals or harmful substances, REME comprises a number of known air purification technologies and sciences in one product. Its active capability works by producing and maintaining similar concentrations of hydrogen peroxide molecules as those found in the outdoor air and combines a process of bipolar ionization. When coming into contact with microbials, the naturally occurring ionized molecules break them down, destroy them and then revert them back to harmless water vapor and oxygen. The bipolar ionization effect causes other airborne particulates to agglomerate together causing them to become larger and heavier and drop out of their air or get captured in HVAC filters. RGF’s REME air purification technology produces 1 quadrillion ionized hydrogen peroxide molecules every second, quickly and safely killing any airborne virus or bacteria, including SARS-CoV-2 on a continuous basis. Its effectiveness has been verified by nationally accredited independent labs and testing bodies in the US and by other governments in numerous tests over two decades, with results also confirming a 99%+ inactivation for highly infectious viruses and bacteria, such as H1N1 or ‘Swine Flu’, SARS, Norovirus, MRSA and Bird Flu, just to name a few. Vaccinate Environments And People Air purification technology drives down the R rate for good by effectively vaccinating the air in which the virus circulates In understanding exactly how active air purification technology works and its capability to successfully destroy COVID-19, it’s clear that it presents an opportunity to drive down the R rate for good by effectively vaccinating the air in which the virus circulates. This strategy is already working its way through the United States with leading brands, like restaurant chain TGI Friday, installing active air purification technology across all establishments and has also caught the attention of renowned insurance market, Lloyds of London, which has installed the technology across all UK offices to ensure its 5,000 plus staff members can return safely to work. Improving the environment For nearly 12 months the world has been coping with COVID-19, describing it as an ‘unprecedented period’ where there is no clear end. However, in vaccinating both people and the environment in which it lives, the virus can be controlled once and for all. Ultimately, with a crippled economy, in excess of 100,000 deaths and a generation of children impacted by the closure of schools, now is the time to accelerate response and change the environments in which the virus circulates, not just the people. 

What’s In Store For HVAC?
What’s In Store For HVAC?

The past six months have been busy for those in HVAC as offices are updated and made safe for people to return. In addition to the various standard checks that need to be carried out, more care is being taken in relation to air movement and filtration to prevent the spread of disease. There is evidence that at least some of the COVID-19 virus can remain suspended in the air and infectious for up to 3 hours. While this is not the main form of transmission, it is vitally important, especially as we are seeing a second increase in infections, that all measures are taken to prevent the spread of the disease. Sick building syndrome In addition to the fundamental elements of HVAC in public buildings, the sector should be looking to the future of technological use; whether COVID-19 is completely wiped out or lingers in the population, we may be at risk of more new diseases in the future. Although maintenance is one of the least visible of building services, it has long played an important role in ensuring the health of buildings. Decades ago, the concept of sick building syndrome was first introduced, showing quite how important our environment is to health. Now, we are being reminded of this on a daily basis in ways that have never been under such scrutiny. We are suddenly hyperaware of what we have touched and who else is breathing our air. In many ways, this new awareness of the unseen is a boon for the sector that has so long been behind-the-scenes, but it also puts it to the test. Potentially stagnant pockets There are numerous recommendations from experts on how to increase safety Governmental guidelines have not specifically required that ventilation and air conditioning be increased in the workplace. Yet, there are numerous recommendations from experts on how to increase safety. At the low-tech end of the spectrum, the use of ceiling and table fans to increase movement in potentially stagnant pockets of air has been suggested. At the other end, technologies that have long been growing in popularity, such as remote monitoring, will really come into their own in the coming months. A particular challenge for the industry as workers return to the office under social distancing guidelines will be accessing certain areas for maintenance. For as long as the virus remains in the population, risk assessments for work will be more complex and non-essential jobs will likely be put on hold where possible. Optical remote sensors Intelligent technology and monitoring systems are already driving the market and will play a role in minimizing contact with others when visiting a site. There is already a great range of tools available: wired sensors, wireless sensors, and optical remote sensors. These allow organizations to monitor vibration, temperature, acoustics, and the power of numerous assets remotely and in real-time. Any issues can be addressed as soon as they arise, minimizing the cost and time that an engineer may need to be in the building. Installing these technologies while buildings are still unoccupied or only partially occupied will also reduce the risk of exposure of engineers to the virus and will improve the efficiency and prolong the life of important assets. Whether a second lockdown takes place or not, these tools will protect building services. Motion-Activated air conditioning Other sensor-based features such as motion-activated air conditioning also have great potential Other sensor-based features such as motion-activated air conditioning also have great potential. These can manage the new hygiene anxiety which pervades public places at the moment. In the longer term, they can be a means of building sustainability practices into the workplace, using power only when needed. Internet of Things (IoT) features such as occupancy sensors have long been growing in popularity to create buildings which are more energy-efficient and promote productivity. Many of these features are demonstrating added value during the pandemic. Occupancy sensors, for example, can be used to ensure that buildings do not exceed safe numbers for social distancing. HVAC systems will be integrated ever further into the IoT approach. Some features of virus reduction, however, have posed a challenge for systems. Air conditioning systems Air conditioning systems, for example, can best reduce the risk of viral transmission through increasing the amount of air which is brought in from the outside into the systems. This will reduce the amount of recycled air but will also increase the temperature fluctuations within the buildings. Other recommendations have included reviewing ventilation strategies, increasing ventilation operating times, deep cleaning filters, and replacing filters more often. Cutting corners on anything which reduces the risk of virus spread will only be a greater loss to the client All of these can potentially see an increase in time and cost required by the client at a time where many companies have been stretched financially. Cutting corners on anything which reduces the risk of virus spread will only be a greater loss to the client in the long run if their employees lose time to illness but it still may be a temptation. Strong working partnership FM providers must work closely with clients to understand their individual fears and needs in such turbulent times. For Anabas, we believe demonstrating expertise and experience is a means of reassuring organizations that they are in safe hands. The future of the pandemic is still unpredictable. While its elimination is hopeful, it is still well worth the investment for many organizations to install the tools which minimize the risk of infection of COVID-19 - or any future infections. Clients are looking for certainty in an uncertain world and data-driven insights and real-time monitoring are ideal ways to provide this. However, the reassurance that comes with a strong working partnership will also be more important than ever. Communicating developments and what they mean for the client, as well as assuring them their priorities are understood can set a provider apart.

ASHRAE Moves To A New Global Headquarters In Metro Atlanta To Achieve Net-Zero Energy Goal

ASHRAE, a global society advancing human well-being through sustainable technology for the built environment, announced a move to its new global headquarters, located at 180 Technology Parkway, Peachtree Corners, Georgia. The Society began renovations in January 2020 on an existing 66,700 ft building, originally built in 1978, on 11 acres of land. Located 10 miles north of its previous headquarters building, ASHRAE joins other innovation and sustainability-focused organizations based in the popular Technology Parkway corridor. Net-Zero energy buildings “ASHRAE’s new global headquarters is a prime example of how we are helping to pioneer a movement that many expect will ultimately make net-zero energy the ‘new norm’ in sustainable design and construction,” said ASHRAE Building Ad Hoc Committee Chair Ginger Scoggins, P.E. “Although new construction of net-zero energy buildings make a lot of headlines, reuse of existing structures is a basic tenet of sustainability – the energy performance of existing buildings must be addressed to substantially impact the 40% of primary energy consumed by buildings.” “ASHRAE’s goal for this project was to renovate a three-story 1970’s era, cheap energy period building into a high-performing net-zero-ready facility in a cost-effective way that can be replicated in the built environment industry,” said Technical Advisory Subcommittee Chair Tim McGinn, P.E. The photovoltaic (PV) system design is currently in progress. The building will be on its way to fully net-zero energy by March 2021 upon the completion of the PV system installation. Digitally connected solutions The headquarters building incorporates several digitally connected solutions such as remote monitoring" Focusing on the Society’s 2020-21 theme, “The ASHRAE Digital Lighthouse and Industry 4.0, the headquarters building incorporates several digitally connected solutions such as remote monitoring and analysis of building performance, with online dashboarding for transparency and advanced Building Automation System (BAS) integration with other systems, such as ASHRAE’s meeting reservations systems.” Other solutions include a digital twin and Building Information Model (BIM), innovative mechanical systems visible through open ceiling around radiant panel clouds and advanced conferencing systems designed to serve as a ‘digital lighthouse’ teaching resource. “ASHRAE’s first-of-its-kind headquarters building was designed as a living showcase of what's possible through technology integration to increase efficiency, protect people and property, and enhance the occupant experience,” said 2020-21 ASHRAE President Charles E. Gulledge III, P.E. “In addition to supporting ASHRAE’s technical standards, innovative product integrations from our generous donors also provide a scalable and repeatable model for a net-zero energy building design.” Fresh air distribution system Examples of technical features include: Radiant ceiling panel system: This is used for heating and cooling & dedicated outdoor air system for outdoor air ventilation with enthalpy heat recovery. Overhead fresh air distribution system augmented with reversible ceiling fans in the open office areas and displacement distribution in the learning center. Six water source-heat pumps (WSHPs): There are four on basement level and two on upper level atrium that will be used to condition these spaces. Demand Control Ventilation (DCV): This will be used for high occupancy spaces in the meeting and learning center. Air distribution is constant volume in office areas and provided by fabric duct, reducing diffuser count and duct branches. Modeling Energy Use Intensity of 17 kBtu/sf/yr. On-site electric vehicle charging stations available for guests and staff. Roof-top and ground mounted photovoltaic solar energy system planned for installation March 2021. 18 new skylights and reconfigured window/wall ratio. Useful daylight illuminance (>300 lux) at the work plane Window Wall Ratio (WWR) 79.9% Existing – New WWR east/west 33.5% - north/south – 41.9%. Prior to the COVID-19 pandemic, ASHRAE had already planned to provide 30% more outside air to the building than the required minimum ventilation rates from ASHRAE Standard 62.1 - Ventilation for Acceptable Indoor Air Quality and will implement other applicable guidance that has been developed by the ASHRAE Epidemic Task Force (ETF) for commercial office buildings. Building occupant health The building is located in a forest setting, close to hotels, restaurants and walking trails The building is located in a forest setting, close to hotels, restaurants and walking trails. A large deck overlooking a lake adjacent to meeting rooms can be fully enjoyed on sunny days. ASHRAE’s headquarters is 12 minutes and 6.2 miles from the Doraville MARTA station for easy access to Atlanta Hartsfield International Airport. The Society’s approximately 110-person staff officially moved into the building at the beginning October. “This move represents another significant milestone for ASHRAE,” said ASHRAE Executive Vice President Jeff Littleton. “In addition to showing our commitment to building occupant health and comfort, our new headquarters building will enable us to provide industry-leading support and service to our global volunteers, while driving innovation that will push our goal of sustainability in action forward.” Successful building campaign A team of ASHRAE volunteers led a highly successful building campaign to garner support for the renovation project. Thirty-one corporate donors committed more than $9.7 million in monetary support and gifts of equipment and services. ASHRAE thanks the following industry partners for their high-level support of the new global headquarters renovation project: NIBE, Cisco, Arkema, Daikin, Price Industries, Belimo, ClimateMaster, ClimaCool, Bell & Gossett, Big Ass Fans, Victaulic, Uponor, Mitsubishi Electric Trane, NTT and PlaceOS. Donors to the building campaign will be listed online and recognized in a special new headquarters commemorative magazine to be published in January 2021. Sustainable built environment ASHRAE’s new global headquarters is an example of an effective built environment" Additionally, ASHRAE members have given over $500,000 to date. In total, ASHRAE has received over $10.2 million from generous stakeholders, making a strong statement about their commitment to ASHRAE’s mission and to a shared vision of a healthy and sustainable built environment for all. “ASHRAE’s new global headquarters is an example of an effective built environment that fully considers the importance of effective operations by installing the systems and equipment in a manner that facilitates operation and maintenance,” said 2019-20 ASHRAE Presidential Member and Building Ad Hoc Committee Member Darryl K. Boyce, P.Eng. “We are grateful to our donors for their generous support and partnership. It is this support that not only shows our donors’ alignment with ASHRAE’s sustainability goals, but helps us to address the challenges of designing and operate buildings in a technology driven environment.”

CoolAutomation Accesses, Diagnoses And Services VRF Systems Remotely With An Innovative Cloud-Based Solution
CoolAutomation Accesses, Diagnoses And Services VRF Systems Remotely With An Innovative Cloud-Based Solution

A new cloud-based solution enables HVAC professionals to access VRF systems remotely to diagnose service issues and lessen the time and costs of providing service. CoolAutomation’s Remote HVAC Service Solution enables HVAC service providers to remotely troubleshoot issues by analyzing real-time and historic data trends and analysis. They receive automatic error and anomaly notifications in their office or on their mobile phones. “The remote service solution provides the tools that HVAC service providers need to offer remote services to their existing clients while attracting new customers who understand the value of remote service for their business,” says Roy Muchtar, VP of Products at CoolAutomation. variable refrigerant flow On site, a CoolAutomation CloudBox connects directly to the VRF and links to the cloud via routers and the Internet. The box shares data on the operation of the VRF to the cloud, where a subscription service enables it to be analyzed to determine any problems. The service solution can connect to any major VRF (variable refrigerant flow) system, including Mitsubishi, Daikin, LG, Samsung, et. al.; and can connect to VRF units from multiple manufacturers in case a customer has installed more than one. The cloud solution begins monitoring information from the VRF at the time of installation If a service provider is migrating from one brand to another, the cloud solution can operate with both if there is a period of overlapping systems. The experience is the same regardless of the VRF brand. The cloud solution begins monitoring information from the VRF at the time of installation, providing a benchmark of how the equipment operates when it is first commissioned. Over time, the technology collects and stores additional data on how it continues to function. remote service solution The service provider receives an email or an alert on their smart phone if something is wrong or if a component is operating outside a defined parameter. The remote service solution also shortens the cycle of service and support. In case service is needed, the provider can diagnose the problem remotely before he or she visits the site; in some cases, remote service can solve the problem. If any anomaly surfaces, the service provider has access to the entire history of system operation to show them what has changed and when. If a site visit is needed, the technician can arrive on site knowing what the problem is and with a plan (and required materials) to solve it quickly. There is no need, for example, for one site visit to diagnose a problem and then a second visit to fix it. cloud-based approach Knowing ahead the complexity of a problem helps service providers decide which technicians (e.g., what level of expertise) to send to the site. The cloud-based approach can also maximize productivity of a service company’s most experienced technicians. A knowledgeable technician can address multiple customer issues in less time, diagnose the problems remotely, and then dispatch less experienced technicians as necessary, knowing exactly what they need to do. The model of sending a technician on site to address every service call, from small to big, will be challenging" In short, the remote service solution is another tool in a provider’s toolbox, helping them improve service, lower costs, and benefit their own bottom lines. There are also benefits for any companies seeking to provide “HVAC as a service” – less cost and more dollars go to the bottom line from any monthly subscription payments. remote service capabilities During the COVID-19 pandemic, the benefits of remote service have become even more obvious as a way to minimize customer visits. In fact, in general, end customers increasingly are coming to expect remote service capabilities from providers.  “HVAC technical service organizations and HVAC contractors will have to make some transition in the way technical service is being provided because of the pandemic,” says Muchtar. “The model of sending a technician on site to address every service call, from small to big, will be challenging in an environment of ever-changing travel restrictions.” The remote service solution also avoids having to set up an appointment to access a system if the building is vacant (because of coronavirus). Also, any anomalies in system operation are less likely to be noticed if the building is empty, so remote monitoring is even more valuable. From the end customer’s perspective, it is likely a service provider can solve any situation before the customer is even aware there is a problem. The time needed for problem resolution is shorter, and lifespan of the system is longer because small problems are addressed before they cause larger problems. In addition to service issues, the information stored in the cloud provides voluminous data that can be analyzed to yield insights on how the system has been used, the performance of various elements, etc. interpreting larger trends The CloudBox, also used for home automation, is already in use in more than 90 countries A rules engine can aid with analyzing multiple factors to interpret larger trends. Rules can be customized to provide alerts based on specific parameters and/or anomalies, and customers can share a library of rules generated by other users. Alerts may include operational analytics (e.g., if the room temperature goes below 60 for 30 minutes), manufacturer alerts (if something is wrong with the VRF), and maintenance alerts (e.g., filter needs to be changed). The new technology, launched in late June, has been beta testing worldwide for several months, including in the United States, the United Kingdom, Israel and Germany. The CloudBox, also used for home automation, is already in use in more than 90 countries. targeting facility managers Use of the technology will soon be expanded beyond VRFs to connect with chillers and other more traditional HVAC systems; however, additional integration is needed to operate with various brands of chillers, each with a different interface. In addition to the remote service solution, CoolAutomation also offers a control application (for end users). Later this year, the company will be introducing an application targeting facility managers that addresses issues such as scheduling and energy consumption
