Intent
To reduce occupants’ exposure to indoor pollutants originating from an adjacent garage.
Requirements
Place all air-handling equipment and ductwork outside the fire-rated envelope of the garage.
Tightly seal shared surfaces between the garage and conditioned spaces, including all of the following:
- In conditioned spaces above the garage, seal all penetrations and all connecting floor and ceiling joist bays.
- In conditioned spaces next to the garage, weather-strip all doors, install carbon monoxide detectors in rooms that share a door with the garage, seal all penetrations, and seal all cracks at the base of the walls.
Projects that earn the EPA Indoor airPLUS label automatically meet the requirements of this prerequisite.

Cost estimates for this credit
On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.
Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.
This information is also available in a full PDF download in The Cost of LEED v4 report.
