by Rebecca Walker — April 10, 2009—AirTest Technologies announced that it recently received an order for 1,000 Carbon Dioxide transmitters that will be utilized by a major Canadian retail chain to upgrade the energy performance of both new and existing stores. This order will provide improved ventilation control for approximately 200 existing stores.
This order is representative of a much larger corporate multi-year commitment of the retailer to implement green and sustainable practices to minimize the energy costs and environmental impact for its 1,100 stores across Canada. The chain has been using AirTest’s transmitters as part of its new construction program for over two years, says AirTest.
AirTest’s self-calibrating CO(2) sensors save energy in buildings by regulating outside air ventilation based on the actual number of people in a space. This ensures that only enough outside air is heated or cooled to meet the immediate needs of occupants, explains the company.
Outside air ventilation can account for 20 percent of the air circulated in a building and 30 percent to 50 percent of the heating and cooling load. A 2005 EPA study of commercial buildings found that more than 80 percent of the buildings evaluated were over-ventilated.
AirTest Technologies specializes in sensors that improve commercial building operating efficiency and at the same time create energy savings. For more information, see the Web site.
