2. Determining factors that affect the transmission of airborne contaminants, such as: ► Supply and return locations ► Pressurization within the space ► Equipment/furniture locations ► Stagnant air zones and air changes per hour (ACH) 3. Testing options, such as: ► Number and location of HEPA filters ► Layout of personnel and equipment within the room ► Location of low-wall returns, which can prevent "dead zones" and recirculation 4. Identifying the occupant safety and cost solutions ► Balance ventilation performance with sustainable design and aesthetics ► Maintain occupant comfort and safety across all environmental conditions ► Mitigate local thermal discomfort factors—drafts, temperature variations, and humidity 5. Substantiating recommendations to stakeholders and decision makers with visual performance predictions ahead of construction documentation (CD) and equipment procurement A Proven Solution to a Growing Concern When many people initially think of the importance of HVAC systems, they think of temperature and humidity control. Despite these prevailing thoughts, the use of HVAC systems to direct airflow is not new. Airflow modeling helps ensure that systems in hospitals keep germs away from patients, workers, and visitors; and ensure that exhaust fumes in their parking garages move away from people. This change in thinking is occurring in buildings beyond the medical profession where building owners believe that investments in strategic air distribution are the right business decisions to protect and maintain the health of the people using these facilities. Today, more and more businesses are starting to think of their HVAC systems in terms of safety: ► As large spaces that have been closed for lengthy periods, such as shopping malls, movie theaters, and stadiums, start to welcome the public back in, an optimized HVAC system can reassure people worried about entering ► When someone at an office building, school, or store tests positive for Covid-19, the flu, or other airborne illnesses, the system can help limit exposure to others in the building
