Mainstreaming high-performance buildings could deliver a 124% return on investment globally through building-related energy cost savings by 2050 says a new comprehensive assessment study of the costs and benefits of low energy building pathways published by the GBPN.

Mainstreaming high-performance buildings could deliver a 124% return on investment globally through building-related energy cost savings by 2050 says a new comprehensive assessment study of the costs and benefits of low energy building pathways published by the GBPN in cooperation with the Central European University’s Center for Climate Change and Sustainable Energy Policy (3CSEP) and Advanced Building and Urban Design (ABUD).

People spend most of their time inside buildings, and buildings are responsible for approximately one third of total direct and indirect energy-related worldwide carbon emissions. Likewise, buildings in the U.S. account for about 40% of total U.S. energy consumption. Future building development will be driven not only by emerging challenges such as vulnerability to a changing climate and resource scarcity, but also by disruptive innovations and societal changes.

The built environment accounts for approximately forty percent of the total energy consumption in developed countries. Because buildings have a long life, the greatest opportunity for energy reduction in the built environment will come from energy conservation in the existing building stock. An overview of the policy challenges presented by the built environment, with an emphasis on existing facilities, is accompanied by a discussion of specific technologies that may have the potential to reduce energy use.
