According to a report from Navigant Research, the future for the energy-efficient HVAC construction industry is strong, with global HVAC market revenue expected to increase from $22.8 billion this year to $47.5 billion within a decade. The analysis says HVAC market equipment accounts for almost 40% of worldwide energy consumption. This makes the market for energy-efficient green HVAC technologies especially important for building owners. “Almost universally, building owners are investing in HVAC equipment to lower energy consumption, lower operating costs, and lower the impact on the environment,” said Benjamin Freas, senior research analyst with Navigant Research. “Not only is this driving incremental increases in the efficiency of equipment, it is shifting design standards — we are seeing variable refrigerant flow systems being designed in place of unitary systems and the use of heat pumps is expanding.” Unlike HVAC construction in the U.S., the Navigant study says the HVAC market in Europe is fl at and HVAC sales in China are declining. (Source: http://www.snipsmag.com)
