Creating “living buildings” requires a new approach to design and construction that recognizes the need to reduce our energy footprint. With this in mind the designers of  the Bullitt Center, a 6-storey headquarters for the Bullitt Foundation, intend to create a sustainable office building that minimizes its environmental footprint.

The new building being constructed in downtown Seattle, and opening in late 2012, uses 1/3 of the energy normally consumed by a standard office building of equal size. The building generates its own electricity using solar arrays, collects rainwater for internal consumption, and treats sewage and wastewater on site. Although still connected to the electrical grid the building systems send power back to the grid when producing beyond the needs of its tenants resulting in net zero electricity usage from utilities.

The builders estimate costs at 33% higher than traditional construction but expect their creation to endure for 250 years…
