["Summary"]
["The U.S. Department of Energy (DOE) and the Commercial Building Energy Alliances (CBEA) have developed this specification for high-efficiency gas heaters with input from manufacturers and other stakeholder organizations. This specification provides a description of required performance characteristics resulting in increased energy savings for gas heaters in commercial buildings. "]
["\nThrough the creation of high-performance specifications, the CBEA members signal their collective interest in more efficient equipment and challenge manufacturers to deliver competitively-priced, innovative products.\n"]
["\nMore on the DOE and CBEA activities, including other energy saving specifications, can be found at:  http://www1.eere.energy.gov/buildings/alliances/"]
