Stantec’s Net Zero Buildings
220,000 sqft - NREL RSF- I - Golden, CO – Built, measured = Net Zero.
120,000 sqft - NREL RSF- II - Golden, CO – 120,000sqft – built, measured = Net Zero
380,000 sqft - SMUD EC-OC (6 buildings) – Sacramento – Built, being measured
125,000 sqft – Salt Lake County DA’s Office building –Designed – In bid phase

Energy Use Intensity (EUI)
Existing Building Stock
By repurposing existing building stock to be more energy efficient when we replace aging systems, and setting appropriate targets for new building stock, SEA can add 50% square footage of buildings to the airport campus—and reduce energy use by 25% from current levels.
