The COVID-19 pandemic is stubbornly persisting and continuing to generate challenges that will not be going away soon. As the economy has gradually reopened, property teams have continued to develop and implement plans to prioritize public health, with only secondary concerns for associated impacts such as increased costs or energy use. The pandemic has brought with it a rethinking of indoor air quality (IAQ) in office buildings, particularly the need to bring in additional outside air and utilize higher levels of filtration wherever possible. This shift will likely require more energy at the same time that the industry is striving for greatly increased energy efficiency targets driven by both internal goals and government mandates.
