As COVID-19 begins to recede in many parts of the world, facilities managers are adapting to the long-term “new normal” of the post-pandemic environment. This new normal follows the largely successful battle facilities managers waged against the virus to keep their buildings and campuses operating safely and to support workers absent from the facility itself but still reliant on systems within the facility to do their work, such as servers and other production equipment.

Today, facilities managers are absorbing a plethora of best practices, lessons learned, and ideas and innovations developed and tested during the pandemic. This includes recommendations and guidance on floor plans and layouts, sanitation measures, and supporting a distributed, or hybrid, workforce. Perhaps the most important factor facilities managers must consider as workers return is the increased emphasis on the heating, ventilation, and air conditioning (HVAC) elements of their buildings.

Prior to COVID-19, HVAC systems’ role in facilities management was central but, at least in most office environments, focused on comfort and efficiency rather than on safety. But post COVID-19, HVAC systems—from their maintenance to their replacement to their functionality—are on the front line of facility cleanliness and worker safety.

Many FM practitioners have created pandemic-based HVAC checklists, for example, and many industry organizations and associations, such as the American Society of Heating, Refrigerating, and Air-Conditioning Engineers in the U.S. and the European Centre for Disease Prevention and Control, both offer impressive libraries for managers to adapt to their specific buildings and missions, from traditional office and corporate campuses to hybrid work environments. These resources are extensive and well worth exploring, and we highly recommend integrating these ideas into your post-pandemic FM practice.

That said, there are more general considerations every facilities manager should include when developing their specific HVAC management plan, regardless of facility type, location, or mission. These considerations are:

• Filtration: If not already done, facilities managers should strongly consider replacing HVAC forced-air filters with high-efficiency alternatives, and then verify their FM plan/Computerized Maintenance Management System (CMMS) calls for adequate filter upkeep and replacement. Note that any changes in filtration should incorporate Minimum Efficiency Reporting Value (MERV) ratings of 11 or higher, depending on your specific environment. This simple change should be the keystone for any building preparing to address pandemic conditions.

However, although High Efficiency Particulate Air (HEPA) filters have demonstrated good performance stopping COVID-19 particles, HEPA filters may not be required for many common office and corporate spaces. Relatedly, a relative humidity of 40–60% helped to limit the spread COVID-19 within closed spaces, so FM may wish to ensure their HVAC systems can achieve this threshold—but even new buildings with state of the art HVAC systems rarely exceed 40% relative humidity, and older systems often cannot exceed much lower levels. The takeaway for facilities managers is explore filtration alternatives, and choose the best solution for your space.

• Cleaning and Upkeep: Mold, dirt, dust, and other airborne debris will, as any facilities manager understands, accumulate in ducts and at vents, compromising air quality and reducing the flow of forced air necessary to mitigate the impact of viruses like COVID-19 and others. Increasing vent and duct inspections, scheduling additional cleanings beyond the recommended one- to two-years currently used as a common standard, and checking for any needed duct repairs on a regular basis can help keep forced air flowing and make for a healthier environment overall.
• Exchange Rate Monitoring: Once an adequate filtration system and maintenance plan are in place, facilities managers can track HVAC cycle rates to identify frequency and duration of each forced air blast. In addition to allowing managers to fine-tune their system to provide enhanced safety and air quality control, this practice also provides an opportunity for potential cost savings, as the data generated from tracking cycle rates can help to reduce fluctuations in temperature and quality. Most systems in modern facilities include Internet-of-Things (IoT) sensors to facilitate tracking, which is normally gauged every one to two weeks.
• CMMS Customization: Every CMMS is tailored to the needs and uses of the building or group of buildings it supports. However, in a post-pandemic world, CMMS tools with built-in capabilities and data capacity to track, schedule, and record safety KPIs will quickly become the norm. This especially true for HVAC input into CMMS software packages, as maintenance, testing, and monitoring are vital to making workspaces as safe as possible. Managers would do well to evaluate the capabilities of their current CMMS tools today, rather than wait for the next pandemic to make changes.

As facilities managers, we have a responsibility to those who use our buildings, campuses, and the entire gamut of other spaces HVAC and other systems support. This responsibility is, in fact, part of the core mission of facilities management. However, in a post-pandemic environment, this responsibility now extends beyond the spaces we manage as an airborne virus or other contagion can spread from our facilities into the wider world, impacting entire cities, regions, and beyond. A robust, well considered HVAC system management and maintenance plan can be the central tenet of a facility well-prepared to weather the next outbreak and to protect not just our users, but our communities as well.
