One of the ways Beaver Creek staff reduced energy use was to purchase and install occupancy sensors at various locations. The occupancy sensor automatically detects changes in occupancy using infrared technology. This switch is ideal for restrooms, closets, and other rarely occupied locations, that need not be lit all day. By reducing unnecessary lighting, the wall switch helps us save energy. The installation of timers is another small step Beaver Creek utilized to save energy. Timers have been installed in areas such as walk in coolers that are only occupied for a short period of time.
Beaver Creek staff also purchased and installed compact fluorescent lights (CFL’s.) The twenty-three watt CFL uses 75% less energy than its 100-watt incandescent equivalent, and lasts 13 times longer. By using energy efficient 23 watt CFL’s, we significantly decreased our energy consumption, which reduced our indirect emissions of greenhouse gasses and harmful pollutants.
The most common commercial lighting in the past has been the 1.5-inch diameter (T12) cool-white fluorescent lamps and transformer-type magnetic ballasts. At Beaver Creek, this type of lighting is more and more becoming a thing of the past.
Beaver Creek Management is dedicated to setting new standards for low power consumption for lighting purposes by applying new technologies to aging buildings. If an existing building uses T12 fixtures and lamps, and they are still in good shape, they are retrofitted with electronic ballast. The electronic ballasts are specifically designed to operate lamps at a lower current that the T12 lamps. Since T8 lamps have identical pin spacing they are easy to install in place of T12 lamps. All new buildings use the energy efficient T8 lighting set-up.
Benefits of the Retrofit include:
• A fixture uses up to 35% less electricity
• T8 lamps have higher light output per watt (efficacy)
• Longer lamp life
• Electric ballasts virtually eliminate lamp flickering
• Electronic ballasts can operate as many lamps on a single ballasts
• Fixture provides quieter operation, no humming
Spruce Saddle Lodge, the resort’s main on-mountain restaurant, purchased a new industrial dishwasher that decreased both water and electrical use. The new dishwasher uses 276 gallons of water per hour versus the 419 gallons per hour used by the previous machine; a 35% decrease in water use and a huge reduction in water heating cost. In addition, we substituted a gas booster heater for the new machine as opposed to the electric booster heater that generally is installed with this machine. This change will result in a $4000.00-$8000.00 annual savings in power consumption. To further these savings, an Ultra-Spray valve manufactured by Fisher was installed a year later on the machine. These spay valves save 65% on water heating and usage costs. It provides powerful performance while using only 1.60 GPM @ 80 PSI.
