Building Green at DNR
Northern Region Headquarters in Spooner

The Department of Natural Resources (DNR) is designing a new Northern Region Headquarters building in Spooner. The project is being designed by Berners-Schober Associates of Green Bay. It is hoped that the building will receive LEED (Leadership in Energy and Environmental Design) Gold certification from the U.S Green Building Council and will be at least 60% more energy efficient than a standard code derived building.

Some of the green strategies that are being pursued include:

• R-17 wall assembly insulation
• R-31.5 roof roof assembly insulation
• Low-E clear, high visible transmittance, Argon filled glazing.
• Auto control dimming of electric lights in conjunction with natural day lighting
• Occupancy sensor control of electric lights in private offices, storage, restrooms, break room, conference rooms, and data center
• Lighting power density (watts/sf) 15% better than code base in data center, corridor, lobby, storage, mech/elec room, restrooms, and break room
• Super-T8 lamps and extra efficient ballasts
• 96% efficient condensing gas boiler
• Under floor air, electrical, and telecommunications distribution system
• Premium efficiency supply/return fan motors and pump motors
• Variable Frequency Drives (VFD) on supply/return air fans
• CO2 control of outside air, occupancy sensor control of VAV boxes, and total heat recovery

We hope construction will begin mid to late 2010.
