This project attempts to broaden the notion of green building design to take into account other design–related issues that have important health consequences, addressing asthma and obesity in a new apartment building in a low income community. We examine how the synergy between environmental benefits and human health promotion is experienced by residents in a lower income community, and whether the health disparities commonly found in low income communities can be attenuated by sustainable, green residential building design. Affordable housing is an underutilized opportunity to intervene broadly in the inter-connected problems of poverty, environmental conditions, and poor health. This includes addressing Active Living by Design to support healthful living by encouraging increased levels of physical activity among building residents, which has multiple health benefits. This approach, for example, encourages increased use of stairways, more outdoor and active versus indoor and passive activity, encouraging walking to local activities, etc. We also address the impact of green management (that is, the actions of facilities maintenance personnel) and of green behavior (such as the actions of occupants) to support the effectiveness of the design in increasing sustainability and improving air quality. The impact of even the best design may be muted or thwarted by poor or limited operation and maintenance (such as changing filters, keeping equipment operating optimally), and/or inappropriate behavior by occupants (approaches to cleaning, adjustments of thermostats, etc.). We will therefore look at the impact of programs that encourage supportive action by facilities managers and occupants. This is a participatory and longitudinal study that incorporates interventions and evaluations at multiple levels across multiple sectors that include (1) building-level policies and programs that can affect all residents and even neighborhood quality of life; (2) apartment-level activities that can improve household economic and energy impact and indoor air quality; and (3) individual level education on healthy eating and active living that can improve health literacy and household health outcomes. A number of features of the building environment are considered. Low-toxin / low-VOC materials, reduced chemical cleaners, integrated pest management, and ventilation using operable windows and mechanical systems are examined for their effects on health and satisfaction. The roof top garden, an aesthetic building design, and onsite services are also evaluated for their role in offsetting the stress of poverty, pollution, inequity, and neglected city neighborhoods.This research was funded by a grant from the U.S. Department of Housing and Urban Development Green and Healthy Homes Technical Studies Program.
