This week, the Bullitt Foundation's Cascadia Center for Sustainable Design and Construction released a report detailing its energy performance metrics. For all you energy nerds out there, this is a pretty exciting development.
The document outlines how the six-story building will meet net-zero energy. The big
highlight is that it releases the planned EUI of the building, or Energy Use Intensity. An EUI score is expressed in units of thousands of BTUs per square foot of gross floor area. Based on 52,000 square feet of gross floor area, the project should have an EUI of 16. Based on 39,000 square feet treated floor area, a common European measurement, it would have an EUI of 21.
I was recently discussing EUI with members of a ZGF team. They told me the average EUI for an office building in the Pacific Norhtwest is 106.
The report also says the U.S. Department of Energy's Zero Energy Building database currently contains no comparable buildings.
The report includes a pie chart with sections for the center's different energy uses. The largest percentage at 23 percent will feed lights. The next highest amount of energy, at 10 percent are pumps. About 9 percent of the building's energy will feed monitors while 8 percent will feed workstations. Toilets will get .2 percent of the building's energy use.
