Indoor Climate Control: The Global Demand for Heating,Ventilating, and Air-Conditioning Equipment

World demand for heating, ventilating, and air-conditioning (HVAC) equipment is expected to rise in absolute terms during the current five-year period, but the rate of growth is slowing. However, growth is still in excess of that recorded by both global building construction expenditures and world gross domestic product. In 2007, $63.1 billion was spent on HVAC. The Asia-Pacific region now accounts for about 45 percent of the total. The two major categories of HVAC are cooling equipment, which accounts for 71 percent of the total, while heating equipment is responsible for the remaining 29 percent. The commercial market dominates the residential market by a ratio of 65:35. There are hundreds of suppliers around the world, but the eight leading firms have about 50 percent of the market.
