Representatives of several housing industry groups said at a news conference on February 7 at the ASHRAE Winter Meeting that general agreement on a proposed international standard for residential ventilation was at hand. However, a negative vote by the National Association of Home Builders (NAHB) in March indicated that the two groups might never agree on a minimum standard for ventilating more airtight modern housing. In rejecting nearly all of the minimum requirements in ASHRAE's proposed Standard 62.2, Dick Morris, senior advisor for the Construction Standards Department of NAHB, told IEQS on March 6, "We're trying to protect housing affordability, which we think is very important." He said that contrary to the Standard 62.2 Committee's estimate that its proposed standard would add about $150 to $250 to the cost of each house, NAHB subsequently calculated a minimum added cost of $700 per house "and much higher in hot, humid climates."
