Leadership in Energy and Environmental Design (LEED®) is an internationally recognized green building certification system. Green Building Rating System, was developed by the U.S. Green Building Council (USGBC), providing third-party verification that a building or community was designed and built using strategies aimed at improving performance across all the metrics that matter most: energy savings, water efficiency, CO₂ emissions reduction, improved indoor environmental quality, and stewardship of resources and sensitivity to their impacts.

LEED projects are awarded Certified, Silver, Gold, or Platinum certification depending on the number of credits they achieve. There are a possible 18 points related to indoor environmental quality. IEQ professionals on LEED certification teams can help plan strategies for earning LEED points and then test to verify requirements have been met. IEQ parameters addressed include several areas such as the implementation of an IAQ management plan during the construction and pre-occupancy phases of the building, minimum compliance with ASHRAE 62.1-2004, environmental tobacco smoke control, monitoring and documenting the outdoor air ventilation rates to all occupied spaces, conducting baseline IAQ tests for Formaldehyde, Particulates, Total Volatile Organic Compounds, 4-Phenylcyclohexene and Carbon Monoxide. Other IEQ parameters included in the LEED IEQ requirements are thermal comfort and lighting comfort. The U.S. Green Building Council (USGBC), along with other key organizations are developing a design guide which will address indoor air quality (IAQ). The guide will describe an integrated process for achieving improved IAQ in all elements of a building.

Besides recognizing, evaluating and recommending control options for environmental health and safety hazards, AEH&S has positioned itself to provide proactive services following the United States Green Building Council's (USGBC) Leadership in Energy & Environmental Design (LEED).

AEH&S can provide indoor-air quality services as detailed in the USGBC's LEED - CI: Reference Guide in order to receive Green Building credits for EQ, 3.2 Air Quality Testing. 

Certification has been recently achieved for the completion of the 24 hour course "LEED for New Construction and accredited Professional Training" sponsored by Florida International University, applied Research Center.
