ATLANTA — As in past years, one of the most popular educational sessions at the 2019 AHR Expo was hosted by the Building Services Research and Information Association (BSRIA). At its standing-room-only session, the U.K.-based research organization offered insights into current cooling and heating trends in the U.S. and around the world.
Raphael Chalogany, general manager, BSRIA Inc., started off the presentation by noting that the building industry is in a state of evolution, especially as the penetration of air conditioning has accelerated since its general adoption in the 1950s. In the U.S. alone, nearly 90 percent of homes are air conditioned by central or individual units, consuming, on average, 18 percent of annual household electricity expenditures.
