Green building covers a number of aspects related to residential and commercial buildings. Existing buildings are estimated to account for approximately 25% of global carbon dioxide emissions. As such, improving the energy efficiency, thermal insulation and heating methods of a city’s residential houses and other buildings is a vital element in achieving significant greenhouse gas emissions reductions. Great advances have been made in recent years in the development of low or zero-carbon and energy-efficient heating and cooling technologies for buildings, which would significantly reduce emissions resulting from buildings.
Ensuring that a city’s new buildings are constructed according to green practices, employing low-carbon and energy-efficient heating and cooling technologies, will help to reduce GHG emissions to make significant progress on the road towards sustainability.
