The National Western Center (NWC) represents a pioneering step in sustainable energy use and environmental stewardship.
Commissioned in January 2022, this project is North America’s largest District Energy wastewater recovery system, showcasing an innovative approach to energy management.
The system processes approximately 3,000 gallons per minute of untreated wastewater, utilizing two SHARC 880 units. The units, with a design capacity for up to 4.6MW, play a crucial role in the 3.8 MW district energy system, providing a robust and reliable source for the onsite heat pump.
This system remarkably covers 90% of the heating and cooling needs for over 1 million square feet of indoor space at NWC.
The system has led to a substantial reduction in carbon emissions, estimated at around 2,600 metric tons CO2e/year, by avoiding the use of fossil fuels.
