Upgrading Commercial Laundry Facilities

This toolkit contains case studies on how wastewater recycling technology and ozone based laundry systems can help your organization find unrealized savings in energy and water, along with guidance on commercial heat pump water heaters.

    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.
    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.
    Wastewater recycling is a market-ready solution that can save commercial washers an average of 365 thousand gallons/month of combined water and sewer and 1,100 therms/month in hot water heating energy.
    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.
    This specification provides a description of required and recommended performance characteristics resulting in increased energy savings for Commercial Storage Water Heaters.
