Make Your Building Energy Efficient with Natural Gas

Is it time to upgrade your facility's equipment? You can realize big savings by switching to more efficient units, especially if they're fueled by natural gas. Take a tour to see what's possible.

Gas-fired packaged rooftop systems, commonly known as gas packs, offer cost-effective, reliable heating and cooling in one unit. High-efficiency systems can reduce operating costs and improve building comfort, resulting in up to 16 percent energy savings for a 10-ton unit. Combustion efficiencies are as high as 97 percent.
Tankless water heaters can be installed in parallel in medium-sized hotels and motels; laundry facilities in hospitals and nursing homes; showers in schools and campgrounds; and restroom facilities in office buildings and college dormitories. Gas-fired tankless heaters tend to have higher flow rates than electric units. Most tankless models have a life expectancy of more than 20 years and ENERGY STAR® certified models use 25 percent less energy than conventional units.
Cooking equipment fueled with natural gas has an operating cost nearly 70 percent less compared to similar electric equipment. Gas cooking also provides better temperature control with instant on/off heat, resulting in faster cooking times. ENERGY STAR certified equipment includes fryers, ovens and griddles with lifetime savings of up to $5,400.
Condensing boilers have a combustion efficiency ranging from 84 to 98 percent, compared to 65 to 80 percent for conventional technology. A second heat exchanger captures the exhaust gas heat from the primary exchanger, which is used to preheat the entering cool water. Reusing the exhaust gas heat results in far lower flue temperatures than those coming from conventional boilers. The lower fuel costs typically provide a payback within two to five years.
Combined heat and power (CHP) system can reduce energy costs and produce enough power to run your entire facility. CHP systems have system efficiencies of up to 92 percent while providing resiliency against power outages. These systems also reduce emissions by up to 50 percent. A typical system consists of a gas-fired reciprocating engine, a power generator and heat recovery.

Did you enjoy the tour? Keep in mind that these are only a few of the gas-fueled options available for your facility. Whatever equipment you install, you'll be happy with the lower costs and smaller carbon footprint. For further information on any of these technologies, search the eLibrary or contact Ask an Expert.
