In Chicago, they have recently built a building providing subsidized housing that is LEED certified. This building is conceptually great as it helps people while helping the environment. A model that every city should adapt!
He notes that the building, designed by Chicago architect Helmut Jahn, is specially designed to use wind power. The roof curves at the edges, like the top of a loaf of bread. As the wind flows over the curve, it accelerates on its way into the turbines.
The roof also houses solar hot-water panels. Rainwater runoff from the property collects in an underground cistern, into which also drains filtered gray water from the building’s showers. This is the first large-scale gray-water system in Chicago. The collected water is used to flush toilets and irrigate outdoor gardens.
In all, the green-design elements added about $1 million to Near North’s construction costs, which totaled $14.1 million. The expected payback period for the added costs is 16 to 18 years
