Study: Health Outcomes and Green Renovation of Affordable Housing 2011

US National Library of Medicine

Results

Adults reported statistically significant improvements in overall health, asthma, and non-asthma respiratory problems. Adults also reported that their children's overall health improved, with significant improvements in non-asthma respiratory problems. Post-renovation building performance testing indicated that the building envelope was tightened and local exhaust fans performed well. New mechanical ventilation was installed (compared with no ventilation previously), with fresh air being supplied at 70% of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers standard. Radon was <2 picocuries per liter of air following mitigation, and the annual average indoor carbon dioxide level was 982 parts per million. Energy use was reduced by 45% over the one-year post-renovation period.

Conclusions

We found significant health improvements following low-income housing renovation that complied with green standards. All green building standards should include health requirements. Collaboration of housing, public health, and environmental health professionals through integrated design holds promise for improved health, quality of life, building operation, and energy conservation.

Low-income families are more likely to encounter environmental health and safety hazards in their homes and communities and are, therefore, disproportionately affected by environmental diseases.1,2 Low-income children are eight times more likely to suffer from lead poisoning,3 and childhood asthma rates are higher in low-income communities.4 Housing affects health directly and indirectly, and the burden of housing-related diseases and injuries is substantial.5 Physical, chemical, and biological exposures in the home that produce adverse health outcomes and associated housing interventions have been reviewed elsewhere.6–9 Data are needed to elucidate the complex links between health, buildings, and communities to enable building owners, community planners, and others to more confidently implement health-based housing interventions. This study sought to determine whether renovating low-income housing using green and healthy principles improved resident health and building performance.
