Multifamily Indoor Air Quality

Measure Description

This CASE Report will investigate the options to reduce energy use and improve indoor air quality (IAQ) in multifamily dwelling units. It will also evaluate the cost-effectiveness and feasibility of a mandatory compartmentalization air leakage requirement and develop a path for a multifamily building to conduct an infiltration test verified by HERS blower door testing on a sample of multifamily units per building or per floor. This CASE Report will include the following four submeasures.

  • Reduce infiltration.
  • Reduced leakage from central ventilation shafts.
  • Balanced ventilation and energy recovery ventilator/heat recovery ventilator prescriptive requirements for some Climate Zones and credit elsewhere.
  • Kitchen exhaust hood capture efficiency.
