According to the EPA, “CHP in commercial and institutional applications is currently 12 percent of existing capacity, providing electricity, steam, and hot water to hospitals, schools, university campuses, hotels, nursing homes, office buildings and apartment complexes.” While this is a positive start, there is significant room to grow.<br /> <br /> On-site utility is an effective energy solution for property owners who want to reduce costs, conserve capital, and im Prove net income. The energy produced from on-site utilities is sold to an individual property as an alternative to the outright sale of energy equipment. On-site utility customers only pay for the energy produced by the system and receive a guaranteed discount rate on the price of the energy. All system capital, installation, operating expenses, and support are paid for and handled by the on-site utility provider. A highly efficient onsite utility typically provides energy savings of 10 percent off the rate charged by your current energy providers.<br /> <br /> Doral Arrowwood Hotel and Conference Center, a 475,000-square-foot property suitated on 114 acres in Rye Brook, N.Y., has already made it to this step. General Manager Steve Mabus says the hotel has been working on its green initiatives for a few years. “We began our green efforts with using various cleaning products and graduated to initiatives such as instantaneous hot water heaters to meet guest demands for reducing energy dependency, installing pool monitors to monitor online all aspects of the swimming pool, and compost machine in the main kitchen, which reduces food waste by approximately 12,000 pounds per month,” Mabus says.<br /> <br /> While each of these measures provided savings, they required capital to initiate and staff time to implement. “The time and expense is well worth the benefits of having these green initiatives in place,” he says.<br /> <br /> The boiler system produced a lot of excess steam, was not efficient, and required too much maintenance. Howard Kaskel, the owner of Doral Arrowwood, reached out to American DG Energy to find out what could be done to help reduce the energy waste, increase efficiency, and assist in their green initiatives. An important objective included conserving capital and minimizing staff distractions.<br /> <br /> After an evaluation of Doral Arrowwood’s current system, it was determined that an on-site utility would provide significant environmental benefits and allow the property’s boilers to operate less, thereby extending the life and reducing operating costs. American DG Energy determined that an on-site utility with 375 kW of CHP system would be the best match.<br /> <br /> Without deploying any capital, the property is projected to save hundreds of thousands of dollars. The system would provide an overall reduction in carbon dioxide, nitrogen oxides, and sulfur dioxide emissions. According to the EPA’s Greenhouse Gas Equivalencies Calculator, the systems are predicted to reduce carbon dioxide emissions as an equivalent to that absorbed by 382 acres of forest and removing 306 cars from the road annually.<br /> <br /> “As a premier hotel in Westchester County, N.Y., we are dedicated to providing our guests with the highest quality experience. We believe this includes delivering an ecofriendly approach our guests can feel good about,” Mabus says. “This CHP system complements the many other eco-friendly steps we have already taken.”
