The U.S. Department of Energy (DOE) has selected Lennox Industries Inc., a subsidiary of Lennox International Inc., as a joint provider of energy-efficient commercial heating and air-conditioning equipment. The winning Lennox products were selected based on initial cost of the unit and annual energy consumption.

The winning Lennox Industries commercial air-conditioners are available in three cooling capacities with energy efficiency ratios (EER) of 11.0 or higher: 90,000 Btu/h, 102,000 Btu/h, and 120,000 Btu/h. These units exceed efficiency requirements set by the federal ENERGY STAR(R) program, being at least 20 percent more energy-efficient than current mandatory federal standards
require. In addition to the units that qualified for the DOE program, Lennox offers high efficiency L Series units in 3-30 ton cooling capacities.

The DOE competition resulted from the need for greater availability of high-efficiency commercial packaged rooftop air conditioners for low-rise commercial-style buildings such as retail stores, schools, clinics, and offices. Executive Order 13123 requires federal agencies to reduce energy use in federal buildings by 35% from 1985 levels by 2010. Minimum product specifications were formulated in consultation with major
buyers, including the Defense Logistics Agency (DLA), procurement arm of the U.S. Department of Defense. Proposed equipment was evaluated using an innovative method of estimating life-cycle cost that explicitly reflects electric power consumption over a range of temperature and humidity conditions
encountered in the course of a typical year.
