Energy-positive

The International Energy Agency (IEA) highlights that operating buildings accounts for “30 percent of global final energy consumption and 26 percent of global energy-related emissions.” The 26 percent figure equates to a combination of direct emissions (8 percent) from buildings themselves and indirect emissions (18 percent) from producing the electricity and heat that buildings use. Buildings that improve their energy efficiency (and self-sufficiency), particularly those that are energy-positive or energy-neutral, will, in addition to significantly lowering costs, improve air quality and comfort levels for their users: in effect, improving the overall health and vitality of people. A number of factors are related to energy eff... もっと見る
