The Augsburg College Library is a library/office building in an urban campus setting. The facility is open 24 hours a day, seven days a week. The Weidt Group served as a resource to BWBR Architects, Ericksen Ellison & Associates engineers, and Northern States Power (now Xcel Energy), the local utility. The building achieved a very high level of energy conservation. Energy and Daylighting design assistance analysis in the Schematic Design and Design Development stages enabled the use of occupancy control of outside air & VAV, scheduling of outside air, variable speed pumps and daylighting controls.

Key Strategies:

• Occupancy control of outside air & VAV
• Scheduling of outside air
• Variable speed pumps
• Daylighting controls

Results:

• Approximately 40% annual energy and operating cost savings
• Approximately 1.2 million pounds of air pollution abated per year
