LEED Certification for Homes – EQ CREDIT: ENHANCED VENTILATION
Option 1. Enhanced Local Exhaust (1 point)
Use one of the following strategies in every bathroom with a shower, bathtub, or spa (i.e., half-baths are exempt) to control the use of the local exhaust fan:
- an occupancy sensor;
- an automatic humidistat controller;
- a continuously operating exhaust fan; or
- a delay timer that operates the fan for at least 20 minutes.
Option 2. Enhanced Whole-House Ventilation (2 points)
Install a balanced whole-house ventilation system (not just exhaust only or supply only) that meets the minimum ventilation requirements of ASHRAE Standard 62.2–2010, Sections 4 and 7, or local equivalent whichever is more stringent.
Program the system such that it does not exceed the standard’s requirements by more than 10%.
For multifamily buildings, meet the above requirements for all in-unit residential spaces in both options 1 and 2.
