Two of the most important HVAC industry issues are energy efficiency and latent capacity. ANSI/ASHRAE/IESNA Standard 90.1- 1999, Energy Standard for Buildings Except Low-Rise Residential Buildings, set new standards for the minimum energy efficiency ratios (EERs) of unitary air-conditioning equipment in the commercial capacity range. The U.S. Energy Policy Act of 1992 stipulated that these proposed energy levels would become mandatory, subject to a review by the U.S. Department of Energy. Even though that review is not complete, availability and sales of units with higher efficiencies have increased to reflect the changes in Standard 90.1.
