If you are out driving around be sure and drive by 846 S. 52nd Street. It is a new Sustainable Design Home. I gathered from Wikepedia, that that means it is a environmentally-conscious designed home. This type of architecture is aware of all the environmental impacts concerned with the building of the home. From the making of the materials, which are either recycled or sustainably produced (meaning they use energy efficiently to make the material), to the picking of the site, to using environmentally friendly methods in building the home. Every step needs to be environmentally friendly.
Sustainable living focuses on more efficient heating and cooling systems, different energy sources like solar hot water, reused or recycled building materials, on-site power generation, rainwater harvesting, and on-site waste management.
They build Sustainably so you can continue to live Sustainably.
