Happy Earth Day! Bullitt Center Opens in Seattle
http://archweekpeopleandplaces.blogspot ... attle.html

The Bullitt Center is a new six-story building in Seattle, Washington, designed by the The Miller Hull Partnership, conceived and built as a forward-looking model of building sustainability. Equipped with a deeply overhanging rooftop photovoltaic array, the building is expected to generate 100% of its energy needs on site, and water needs will be provided by harvested rainwater routed to a 56,000-gallon (212,000-liter) basement cistern.

As much as 82% of the building's area is day-lit, contributing to an energy use intensity of just 4.7 kilowatt-hours per square foot per year (50.5 kWh/ square meter/ year, 16 kBTU/sf/yr). This EUI is in range with the energy criteria of the Passive House standard, and corresponds to a projected total energy use of 230,000 KWH/year, about equal to the anticipated annual production of the 242-kilowatt photovoltaic system.

Total energy use projected to be equal or less than the solar power production qualifies the building for the "net zero energy" title.

The building employs natural ventilation for its perimeter spaces, supplying fresh air and summer-time cooling. An array of twenty-six 400-foot-deep (122-meter-deep) ground-loop heat-exchange wells helps drive the center's radiant heat distribution system.

This is a very good building. Much superior to the building in San Francisco.
