DALLAS, TX – Feb. 22, 2005 – For the third consecutive year, the Environmental Protection Agency (EPA) and the Department of Energy (DOE) have selected Lennox Industries Inc., a subsidiary of Lennox International Inc. (NYSE: LII), as an ENERGY STAR® Manufacturing Partner of the Year for Lennox' outstanding contribution to developing, manufacturing, and promoting energy-efficient products. Lennox is the only heating, ventilation, and air-conditioning manufacturer ever to be chosen for the annual EPA award. According to the EPA, more than 60% of the American public recognizes the ENERGY STAR label, making ENERGY STAR the national symbol of energy efficiency. "Partners like Lennox exemplify the success and importance of the ENERGY STAR program," said Kathleen Hogan, director of the EPA's Climate Protection Partnerships Division. "By offering the most innovative, energy-efficient products, the consumer wins and so does the environment. Lennox' products show you really can have it all—innovative, value-added features and energy savings." While thousands of organizations participate in the ENERGY STAR program, the annual award is presented to only a select few. "As Lennox Industries celebrates its 110th anniversary in 2005, we are pleased and proud to once again be honored by the EPA in this landmark year," said Bob McDonough, president and chief operating officer, LII Worldwide Heating & Cooling. "It is recognition not only for our longstanding commitment to designing and manufacturing the most energy-efficient consumer products, but for the growing success of the entire ENERGY STAR program. We are proud to be ENERGY STAR partners." Lennox reached a new record in 2004 for energy-efficient product introductions, with 97% of all products in the premium Dave Lennox Signature™ Collection ENERGY STAR-qualified. Lennox also hosted a utility partnering conference in June, which was attended by utilities and energy-efficient alliances. The ENERGY STAR message continued to be communicated prominently on the Lennox website, while consumer education through Lennox advertising doubled its number of impressions to two billion in 2004. "Through our products, targeted advertising promotions, dealer training and support, and educational marketing of our residential and commercial product lines, Lennox continuously reinforced the important message of energy efficiency through the ENERGY STAR program in 2004," McDonough said. "We fully intend to continue our leadership position in this important consumer program." ENERGY STAR was introduced by the US Environmental Protection Agency in 1992 as a voluntary market-based partnership to reduce air pollution through increased energy efficiency. Today, with assistance from the Department of Energy, the program offers businesses and consumers energy-efficient solutions to save energy, money and help protect the environment for future generations. More than 7,000 organizations have become ENERGY STAR partners and are committed to improving the energy efficiency of products, homes and businesses.
