This paper reviews and summarises research studies of residential energy efficiency (EE) and related ventilation upgrades, discusses ways that programmes monetise occupant health co-benefits, highlights innovative programmes that combine EE and health-focused home repairs and identifies where research gaps exist, and/or where research can be improved and leveraged.
Key study findings include:
- Occupants can experience fewer asthma symptoms and respiratory related emergency department (ED) visits after EE.
- Occupants report better physical and mental health after EE.
- Programmes delivering EE with added home repairs and client education can produce more significant improvements in asthma symptoms and indoor environmental conditions.
- Improvements in occupant health are strongest among vulnerable groups: lower income households and residents with pre-existing health conditions linked to housing risks.
- Whole house ventilation strategies using heat or energy recovery ventilators (HRVs or ERVs) can reduce asthma and respiratory symptoms in children with pre-existing risks. Such strategies are increasingly being considered in EE programmes.
- Homes receiving EE can experience increases in radon or formaldehyde; ventilation systems may offer the potential to reduce radon in such homes.
- The majority of studies were conducted in single family lower income homes located in predominately northern heating climates.
