Based in Cambridge, Massachusetts, Kirkland Cleaners is a small business that wanted to help the city meet its goal of lowering electricity and water consumption by 10 percent. After getting a comprehensive energy audit, the owners decided to replace their 25 year-old water heating system with three new tankless water heaters, replace their top-loading washing machines with more-efficient front-loaders, and install automatic switches to shut off lights whenever possible. Now Kirkland Cleaners is saving 20 percent on its gas bill and has reduced its water consumption by 100,000 gallons per month, all with a four-year simple payback period after utility incentives.
