The most successful, long term, low-income housing projects are those that use sustainable design and address the social, cultural, and economic needs of residents. Traditionally built low-income housing projects are associated with high crime rates and high mortality rates among the residents who live in them. They do not provide for the needs of residents, resulting in many of the problems these low-income housing projects face today. These problems range from endangerment of human life, psychological afflictions due to the high stresses that are endured by residents, disease epidemics. they provide to a wide range of people. Residents of low-income housing projects that are sustainably built can benefit in a myriad of ways. Sustainable design incorporates energy-efficient and water-conserving technologies in the buildings as well as in the appliances of these buildings. As a result many low-income residents of sustainably designed housing developments benefit from lower utility bills. Techniques, like designing spaces with a number of large, well insulated windows are aimed to cut down on electricity costs (Brooke, Cohen, Hampton). They also found that the buildings studied were able to save up to 50 percent more on energy costs, up to 20 percent more on water, and also save 20 percent more on electricity costs (Cohen). In Seattle, Washington, sustainably built [green] low income housing projects have been developed using “systems, appliances, lighting fixtures and landscaping that save money and water, low-fume paint and carpeting, and durable materials that do not have to be replaced as often” (Cohen). Residents benefit from low utility costs, and housing developers and owners benefit with government subsidies, lower operating costs, and buildings that are sturdier than those traditionally built for low income housing.
