ODESSA, FLA.—Hasek Communications, the Odessa, Fla.-based publisher of Green Lodging News, has added a Solar America Solutions case study to its website. The case study details the installation of a 20-panel SunQuest 250 Solar Thermal System at the 439-room Grand Hyatt Atlanta in Buckhead. The challenge was to reduce the annual cost of heating water for guestroom use, while providing an acceptable equipment payback period. The hotel was spending approximately $43,000 per year to heat water for guestroom showers. The new SunQuest 250 system pre-heats the water entering the three-boiler array in the 26th story mechanical room to 140°.
The result has been a more than 50 percent reduction in guestroom DHW natural gas costs with a complete equipment payback in 3.9 years. These results are based on actual gas consumption figures provided by the Grand Hyatt Atlanta.
