DOE offered commercial building owners the opportunity to partner in heat pump water heater demonstrations. Participating organizations received a discounted high-efficiency product in exchange for their cooperation with the field study and saw firsthand the performance, energy savings, and economic benefits of commercial heat pump water heaters.
DOE funded evaluations of a wastewater recycle system at the Grand Hyatt Seattle and of ozone systems at the Charleston Place Hotel and the Rogerson House Assisted Living Facility, saving $135,000 in the first year.
DOE funded evaluations of ozonation at the Charleston Place Hotel in Charleston, SC, and the Rogerson House assisted living facility of Boston, MA and found up to 60% savings in hot water requirements.
Wastewater recycling is a market-ready solution that can save commercial washers an average of 365,000 gallons/month of combined water and sewer and 1,100 therms/month in hot water heating energy.
This specification provides a description of required and recommended performance characteristics resulting in increased energy savings for Commercial Storage Water Heaters.
