• The building will use 50% less energy than if it were built to current commercial codes
• It will achieve LEED Platinum rating
Innovation for Our Energy Future
•Building orientation:
• Narrow east-west oriented floor plate (60’ wide) enables daylighting and natural ventilation

13
•100% of the workstations are daylit
•No employee more than 30 feet from a window
• Triple glazed windows with aggressive window shading, including “smart windows” that automatically dim

• The transpired solar collector on the RSF is technology originally developed at NREL
Innovation for Our Energy Future
• Labyrinth thermal storage in the basement crawl space stores thermal energy to provide passive heating of the building
