A home seeking certification has installed a CO detector in the mudroom adjacent to the garage. Which additional measure is required under EQ 10.2 Minimize Pollutants from Garage?

The requirement for weather-stripping the door to the mudroom is essential for minimizing pollutants from the garage. By properly sealing the door between the garage and the mudroom, the transfer of pollutants, such as carbon monoxide, fumes, and particulates, from the garage into the living space is significantly reduced. This mechanical barrier helps protect indoor air quality by preventing contaminants generated in the garage, such as from vehicles or stored chemicals, from entering the adjacent living areas of the home.

The choice to install an air purifier in the garage, utilize automatic garage doors, or ensure mechanical ventilation in the garage, while beneficial for various aspects of air quality, do not directly address the need to create a specific barrier preventing pollutants from moving into the adjacent living spaces. Weather-stripping effectively fulfills the specific intent of EQ 10.2 by enhancing the home's ability to safeguard against harmful emissions originating from the garage area.
