"Great River Energy, the fifth largest generation and transmission cooperative in the United States, moved into their new 180,000 square foot headquarters last April. In October, 2008, their building became the first LEED platinum commercial building in the State of Minnesota. In this presentation, mechanical and electrical engineers from Dunham will describe the strategies used to attain significant reductions in required energy for lighting, heating, cooling and ventilation. The team first looked to earth’s own renewable resources, harnessing the sun for both lighting and power generation, an adjacent lake as a geothermal source for heating and cooling, and the wind for additional on-site power. Early integration with the architectural design ensured optimized use of these resources. Several combinations of mechanical systems were then analyzed and selected to best leverage these resources through combining existing technologies in a unique way. A comprehensive approach to sustainability also addressed water conservation strategies, which include rainwater harvesting. The project successfully met its aggressive goals, and has resulted in numerous state and national engineering awards."
