OBJECTIVES:
Assess the benefits of green renovation on self-reported health of primarily elderly residents of a low-income public housing apartment building.
DESIGN AND SETTING:
Using questions from the Medicare Health Outcomes Survey, we interviewed residents at baseline and 1 year after green renovation of their 101-unit building in Mankato, Minnesota, comparing self-reported mental and physical health outcomes of 2 sets of residents (all-ages: median, 66 years, n = 40; elder: median, 72 years, n = 22) with outcomes for 2 same-aged low-income Minnesota comparison groups taken from Medicare Health Outcomes Survey participants (n = 40 and 572, respectively).
PARTICIPANTS:
STUDY GROUP:
Mankato apartment building residents.
INTERVENTIONS:
Green renovation including building envelope restoration; new heating, electrical, and ventilation systems; air sealing; new insulation and exterior cladding; window replacement; Energy-Star fixtures and appliances; asbestos and mold abatement; apartment gut retrofits; low volatile organic chemical and moisture-resistant materials; exercise enhancements; and indoor no-smoking policy.
MAIN OUTCOME MEASURES:
Self-reported health status including Activities of Daily Living and Veteran’s Rand 12 (VR-12) survey results; housing condition visual assessment; indoor environmental sampling; and building performance testing.
RESULTS:
The all-ages study group’s mental health improved significantly more than the comparison group’s mental health on the basis of mean number of good mental health days in the past month (P = .026) and mean VR-12 mental component score (P = .023). Sixteen percent fewer all-ages study group people versus 8% more comparison group people reported falls (P = .055). The elder study group’s 9% improvement in general physical health was not statistically significantly better than the elder comparison group’s decline (6%) (P = 0.094). Significantly fewer people in the all-ages group reported smoke in their apartments because of tobacco products (20% vs 0%, P = .005), likely reflecting the new no-smoking policy.
CONCLUSIONS:
Green healthy housing renovation may result in improved mental and general physical health, prevented falls, and reduced exposure to tobacco smoke.
