Nobody loves acronyms more than the military and intelligence agencies, so “NAC”, the popular abbreviation for “No Apparent Change”, is commonly used in updated reports to indicate that whatever is currently being observed or monitored has not changed much from previous versions, a convenient way to save time and space.

In this case, I am reporting that NAC applies to the newly updated official policy of the National Association of Home Builders on green building and sustainability. Allow me to explain…

Last week at IBS, GuildQuality released results from a a national survey of homeowners who purchased a National Green Building Standard (NGBS) certified green home built within the last three years.

A RECENT SURVEY CONDUCTED ON BEHALF OF WHIRLPOOL Corporation and Habitat for Humanity International by the NAHB Research Center showed that 74 percent of consumers believe that less than a quarter of their home can be categorized as “green.” The complete study reported opinions from consumers and builders on various topics related to green home building.

THE SIZE OF NEW SINGLE-FAMILY HOMES completed declined last year, dropping to a nationwide average of 2,438 square feet, according to detailed information about the characteristics of new homes completed in 2009 that was released recently by the Census Bureau.

On September 15 the National Association of Home Builders (NAHB) issued a news release titled, "Home Buyers Want to Save Energy—But Only at the Right Price, NAHB Survey Shows."
