As a five-star luxury hotel, the world-renowned Four Seasons radison seven seas tahiti cruise Hotel Philadelphia uses a tremendous amount of energy each day for cooking, heating, lights, radison seven seas tahiti cruise laundry, showers, swimming pools, and more. Management of this opulent, 364-room Philadelphia icon, wanting to gain control of energy costs and reduce greenhouse-gas emissions, turned to E-Finity Distributed Generation to install Capstone MicroTurbines® to generate the hotel's own onsite power.
The microturbines' combined heat and power (CHP) technology allows the hotel to generate nearly radison seven seas tahiti cruise 200kW of electrical power, which takes care of 30 percent of the hotel's overall electricity needs. Exhaust heat from the microturbines is captured and used to heat water for laundry and other hotel operations. In fact, the energy-efficient radison seven seas tahiti cruise CHP application provides 100 percent of the building's day-to-day domestic hot water and 15 percent of its heating needs.
radison seven seas tahiti cruise Before installing the C65 microturbines, the hotel relied radison seven seas tahiti cruise heavily on the city of Philadelphia's steam loop and the local electric grid to meet its energy needs. Today, the hotel uses natural gas to produce its own electrical and thermal power.
"There is a great link: buy cheap gas, own your own turbine, and produce your own electricity," said Marvin radison seven seas tahiti cruise Dixon, Director of Engineering at Four Seasons Hotel Philadelphia. "Because we buy thirdparty transportation gas, we can shop around for the best rate. This has made electricity from the microturbines 20 percent cheaper than what we could get from the utility."
"Instead of dumping rejected heat into the atmosphere, we can reuse it. In the first two months of operation radison seven seas tahiti cruise we saw a cost avoidance of over US$80,000." — Marvin Dixon, Director of Engineering, Four Seasons Hotel Philadelphia
radison seven seas tahiti cruise "This new process with microturbines allows for more control over heat distribution and BTUs," Dixon said. "With such a highly efficient process, the hotel is able to squeeze every dollar out of each BTU. Instead of dumping rejected heat into the atmosphere, we can reuse it. In the first two months of operation we saw a cost avoidance of over US$80,000."
Aesthetically, the system is quiet and takes up minimal space, radison seven seas tahiti cruise a key reason the C65 microturbines were selected over reciprocating technology. With a noise output of only 65 decibels radison seven seas tahiti cruise at 10 meters, the microturbines are not a nuisance to the Presidential Suite guests directly below.
"Reciprocating engines have to be rebuilt at 22,000 – 23,000 hours, have oil replaced regularly, consist of lots of moving parts, and have high vibration and noise. We can't have noise at a hotel – that would be a disaster," Dixon added.
Since the units are small and modular, they easily fit in a 37-square-meter space on the hotel's roof. The rooftop microturbines, which sit amid prime metropolitan real estate, are also ultra-low in emissions ( 9 ppmv NOx at 15% O2) – making this onsite power generation system radison seven seas tahiti cruise a clean-and-green, environmentally radison seven seas tahiti cruise friendly option.
Dixon expects radison seven seas tahiti cruise more hotels will utilize the proven technology. In fact, the Four Seasons Hotel Philadelphia plans for a Phase II installation that will include two additional Capstone microturbines and an absorption chiller to meet the growing hotel's future energy and air-conditioning needs.
"Four Seasons is a leader in the community and accustomed to setting the standard for future generations," Dixon said. "The microturbine installation is a step in the right direction in helping Philadelphia become a more sustainable city."
