The MEP-intensive Thermal Energy Center [TEC] project located at Microsoft’s Redmond, Washington headquarters serves as the powerhouse for the new campus. 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 features solar panels, chillers, thermal energy storage tanks, and cooling towers to distribute clean energy. 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.

Approach Spotlight

Geowells

A geothermal heat exchange system is in the works to support Microsoft’s carbon negative goal on campus. Heat stored in thermal energy storage tanks will provide the campus with short-term needs and geowells will store heat for seasonal use. Approximately 75 of the 875 planned geowells have been installed to a depth of 550 feet. This process requires close coordination and detailed planning with the other general contractors and subcontractors on site.
