Focused on Energy Efficient Building and Environmentally Sound Construction
The Oikos® site is devoted to serving professionals whose work promotes sustainable design and construction. That's a broad goal, but then environmental sustainability touches virtually every aspect of a building. Oikos is a greek word meaning house. Oikos serves as the root for two english words: ecology and economy. That may seem contradictory at first, but it makes perfect sense.
