RSF Energy Design Key Features Daylighting – Reducing Lighting and Cooling Loads –100% Workstations Daylit Thermal Management – Storing and Using Free Energy –Triple Glazed Windows –Shading –Precast Concrete Insulated Panels –Labyrinth –Radiant Heating and Cooling Energy Efficient Data Center with Heat Recovery Under Floor Ventilation Designed for Easy Aftermarket Addition of Solar Electric Panels 10

11 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 12

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 14

15 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 16

Removing Desktop Printers Saves ~460 Watts/Printer Sensor-controlled LED task lights 6 Watts Fluorescent task lights 35 Watts Desktop Computer (Energy Star) 300 Watts 24” LCD Energy Efficient Monitors 18 Watts Typical 19”-24” Monitors Watts Laptop 30 Watts Removing personal Space Heater saves 1500 Watts Energy efficient workspace….requires new occupant behavior VOIP phones 2 Watts 17 iGo Power Smart Towers Reduces “vampire” energy use Multi-function Devices 100 Watts (continuous)
