IAQ + Ventilation + Energy
must work together for a healthy, efficient and sustainable building
We can help make the occupied spaces in your buildings & businesses healthier, safer, more efficient & sustainable
IAQ = Indoor Air Quality | ACH = Air Changes/Hour (OA) | ACHe = Equivalent Air Changes/Hour | ECAi = Equivalent Clean Airflow / Person (ASHRAE 241) for Infection Risk Mitigation Mode
ASHRAE Epidemic Task Force Updated Airborne Transmission Guidance
Buildings are built for people. Without people, there’s no need for buildings. Let’s take care of the people, as well as the buildings.
Improve IAQ & Control Infectious Aerosols + Reduce HVAC Energy Use & Carbon > Net Zero Energy
Clean the Indoor Air First
“It is the responsibility of building owners & businesses to insure IAQ in their indoor spaces and to reduce the risk of disease transmission.“
– National Strategy for Improving Indoor Air Quality – Johns Hopkins Center for Health Security –
First-Ever Pathogen Mitigation Standard: ASHRAE Standard 241 establishes minimum requirements for controlling infectious aerosols and reducing the risk of disease transmission in new and existing buildings. Included are requirements for both outdoor air system and air cleaning system design, installation, commissioning, operation, and maintenance to reduce exposure to infectious aerosols.
Progressing from
ACH to ECAi
from Air Changes/Hour to Equivalent Clean Air Flow/Person
Current minimum ventilation requirements in ASHRAE Standard 62.1 are not sufficient for airborne disease mitigation. Providing more acceptable rates as required in the new ASHRAE Standard 241-2023 can significantly contribute to creating safer and healthier indoor spaces. ACH (air changes/hour) is a measure of airflow relative to the room volume, it does not take into account occupancy. It is not a meaningful value when assessing the concentration of pollutants. The new metric ECAi (equivalent clean air flow/person) takes into account occupancy and the concentration of pollutants.
May 16, 2023 | CDC: Aim for 5 ACH/hour in Buildings. The Centers for Disease Control and Prevention (CDC) updated its “Ventilation in Buildings” guidelines to include a discussion on “How much ventilation is enough?” to help prevent airborne disease transmission (5 ACH).

The primary transmission route of viruses & other pathogens is airborne. Improving the Equivalent Clean Air Flow/Person (ECAi) in occupied spaces is a bigger determinant in controlling viruses and other airborne pathogens, than increasing the Outside Air delivered by the HVAC system!
