The MEP-intensive Thermal Energy Center [TEC] project located at Microsoft’s Redmond, Washington headquarters is a highly sustainable alternative to a traditional large campus central utility plant. The centralized heating and cooling system, fueled by a 6.5-acre field of 900 geowells, utilizes the Earth’s thermal energy and disperses 850,000 gallons of water to control campus temperatures. The TEC also leverages other clean energy systems such as solar panels, chillers, thermal energy storage tanks, and cooling towers. Affectionately known as The Machine in the Woods, the TEC aims to reduce campus energy consumption by 50% and water use by 8 million gallons.
