This interesting article in GreenSource describes how Seattle-based architecture firm, Weber Thompson takes a "less-is-more" approach to sustainable design. The 40,000 sf Terry Thomas building was designed to, "operate efficiently without using a lot of expensive technology". It's central courtyard works with vents, controls, and window openings to channel warm air out and cool air into the building, making air conditioning unnecessary. Energy consumption was cut by 50% without the use of photovoltaic technology, and the building received LEED-Platinum (interiors) and LEED-Gold (core & shell) ratings. Check out the image gallery for a closer look at this impressive building.
