Indoor air quality testing services for LEED certification


LEED, which stands for Leadership in Energy and Environmental Design, is a green building certification program developed by the U.S. Green Building Council (USGBC). LEED focuses on various aspects of environmentally sustainable building practices, including indoor air quality.

LEED Indoor Environmental Quality (IEQ) credits address indoor air quality as one of the key criteria for achieving certification. The Indoor Environmental Quality category includes prerequisites and credits related to factors that contribute to the overall quality of indoor environments.

Within the LEED framework, there are specific criteria for IAQ:

Minimum IAQ Performance is a prerequisite that mandates adherence to the indoor air quality standards set by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE). This establishes a foundational level for IAQ.

Enhanced Indoor Air Quality Strategies go beyond the minimum requirements. Buildings earn LEED credits by implementing strategies such as increased ventilation and measures to reduce indoor pollutants, contributing to an improved indoor environment.

The Indoor Air Quality Assessment credit encourages conducting an assessment after construction and before occupancy. This step ensures that the building's systems operate as intended and meet the specified indoor air quality goals. It serves as a verification process for the effectiveness of the implemented strategies.

ActionsActions and advice

The extent of indoor air quality testing necessary varies based on the specific version of LEED certification applicable during the application and the targeted credit level, whether minimum or enhanced. Evaluations of air pollutant levels should occur before the initial occupancy and, if necessary, periodically thereafter. Common pollutants subject to testing encompass a variety of volatile organic compounds (VOCs), aldehydes, particulate matter, ozone, carbon monoxide, and dioxide.
