Labs21 Offers Energy-Efficiency Tips
Laboratories for the 21st Century (Labs21), co-sponsored by the Environmental Protection Agency and the Department of Energy, is enlisting laboratory operators in an effort to corral energy consumption and cut attendant costs. Many factors have contributed to the saving of 533 trillion Btu. On a square-foot basis, laboratories can consume 10 times the energy of a typical office building. Energy-efficient steps laboratory operators are taking include installing energy- and water-efficient equipment; incorporating sustainable-design elements into new construction; improving operation-and-maintenance techniques, recovering exhaust heat energy, and processing cooling-water energy recovery; and using geothermal ground-source heat-pump systems...[MORE]
