Step up to the Challenge: Cleaner Air in Buildings

How to Improve Indoor Air Quality Plus the Innovations Needed to Remediate Concerns.

Indoor Air Quality Standards are now Higher than Ever

Collectively, we all measure the health of the water we drink on a daily basis and the outdoor air pollutants that affect our breathing everyday, but why has indoor air quality been an afterthought? As Americans, we spend 90% of our time indoors so setting higher standards and guidelines for indoor air quality (IAQ) has been long overdue. The Biden-Harris administration, in relation to creating the COVID-19 Preparedness Plan, realized IAQ should be top of mind for all building owners and operators to expedite getting back to a ‘new normal’ and therefore launched The Clean Air in Buildings Challenge. In March 2022, the White House delivered the call to action and included important steps for building stakeholders to follow and meet the challenge. By bringing higher standards for indoor air quality into focus, along with some innovation in how to remediate air quality concerns, healthier buildings are more attainable than ever.

As part of the Clean Air in Buildings Challenge, the Environmental Protection Agency (EPA) published a best practices guide for improving indoor air quality and reducing the risk of spreading dangerous airborne particles. Developed in collaboration with many federal agencies, including the Department of Energy and CDC, the guidelines provide basic principles and actions recommended to improve IAQ in buildings to help reduce the risk of airborne viruses and other contaminants.

Key actions for facility owners and operators outlined in the challenge are to:

  • Create an action plan and assess risk within your space.
  • Optimize fresh air ventilation.
  • Enhance air filtration.
  • Deliver clear communication and awareness to your community.

By assessing your space and needs, one or multiple solutions to improve indoor air quality may be needed. 

Cleaner Air Starts with a Layered Approach

In order to achieve clean indoor air, there are certain requirements developed by ASHRAE, the American Society of Heating, Refrigerating and Air-Conditioning Engineers, in regards to the number of air changes per hour (ACH) needed. ACH is how many times air in a given space is being replaced.

Factoring in room size, number of occupants within the area and room activity, ACH requirements range from 2-3 ACH for commercial buildings to 8+ ACH for hospital settings.
