1.5.2 Elec./Mech. Demand
The investment in energy efficient appliances, electrical lighting and sensor technology greatly reduces energy demand and operational energy cost.
Energy efficient appliances and electrical lighting technology (i.e. Light Emitting Diodes, LEDs). Photo sensors and motion sensors adjust electrical lighting needs to exterior and environmental conditions (daylight intensity and human motion). ENERGY STAR provides free Web-based tools, calculators, resources and training to measure, track, and benchmark energy performance. The Target Finder at Energy Star creates a program-specific, site-specific benchmark for annual energy use [KBTU/sf*yr].
The U.S. Department of Energy’s Appliances and Commercial Equipment Standards Program develops test procedures and minimum efficiency standards for residential appliances and commercial equipment. The integration of sensor technology into projects can be coordinated during construction documents. Use the Target Finder to set performance benchmarks. For energy use approximation, owner provides occupancy and equipment use so engineers don’t have to estimate.
Buildings that comply with and earn the ENERGY STAR are the top performers for energy efficiency nationwide and use about 35 percent less energy than average buildings. Motion and photo sensors maximize efficiencies by supplying electricity on demand.
Reduced energy use, lowered peak-time demands, more power supply stability and reduced operational energy cost. In areas of the developing world that lack an established electrical grid, LEDs can provide electrical lighting powered by solar sources, due to their low power requirements.
Applicable to all building types and market sectors.
