Return on Investment for Green Heating and Cooling Systems
According to the US Department of Energy, heating and cooling account for 56 percent of a home’s total energy use. With rising fuel costs and the depletion of natural resources, energy conservation has become a focal point of research in recent years. Some of the most commercially viable next-gen green HVAC technologies are geothermal heating and cooling, chilled beam systems, night-sky cooling, and thermal energy storage. So how do these systems compare, and what kind of return on investment (ROI) can homeowners and business owners expect from them?
