Current guidelines from the Centers for Disease Control (CDC) and The American Society of Heating, Refrigeration, and Air-conditioning Engineers (ASHRAE) recommend building owners and facilities managers reduce the transmission of diseases from airborne particles by improving the operations of the building ventilation systems by:
- Increasing the percentage of outdoor air inside their buildings as long as the temperature can be maintained in a comfortable range.
- Increasing total airflow supply to occupied spaces and disabling demand control ventilation.
- Flushing the air in a building for two full hours prior to first expected occupancy.
- Flushing the air in a building again for two full hours post-occupancy or after closing.
- Maintaining humidity between 40% -60% while being careful not to create condensation conditions that can lead to mold growth.
- Verifying your BAS sensors, equipment and control sequences are operating properly.
- Monitoring and reporting on temperature and humidity status in all spaces throughout the building.
- Programming your system (if possible) to use outside air to maximize airflow and free cooling.
- Ensuring your space temperatures stay above the recommended dewpoint temperature.
- Programming your system for pre and post occupancy building flushes or purges.
These measures can go a long way towards maximizing your energy efficiency while still providing a healthy and safe environment, as recommended by the CDC and ASHRAE.
