ATLANTA, GA — ASHRAE’s Standard 62.2P, which sets mechanical ventilation rates for new single-family homes, would significantly change the way hvacr contractors design and install heating-cooling equipment in the single-family houses America’s homebuilders erect every year.
It’s a huge market. Last year, 1 million central air conditioners were installed in the 1.3 million completed new homes. Of particular interest to contractors is the added layer of expectation of occupants’ comfort in a building, which would require a fair amount of new equipment.
