Project Description:
The Green Rehabilitation of Elder Apartment Treatments (GREAT) study was one of the nation’s first examinations of the health outcomes among older Americans following rehabilitation using green healthy housing methods. While healthy housing has traditionally focused on childhood diseases and injuries associated with housing quality, the GREAT study asked whether improvements might also occur in the at-risk and growing population of elders.

The site, renovated to Enterprise Green Community Standards and achieving LEED Silver certification, consisted of 101 independent living units at Orness Plaza, a low-income apartment building in Mankato, MN. The study hypothesized that green healthy housing rehabilitation of public housing could improve the mental and physical health of residents. NCHH led evaluation activities, including the development of assessment protocols, data entry and analysis, execution of quality assurance activities, and completion of evaluation reports.

The green renovation (e.g., improved ventilation, moisture and mold reduction, and various safety measures) resulted in improved mental and general physical health, prevented falls, and reduced exposure to tobacco smoke.
