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). It offers a first attempt to quantify the global and regional cost implications of ambitious scenarios for implementing large-scale energy efficiency improvements in buildings.

A measure or package of measures is cost-effective when the cost of implementation is lower than the value of the benefits that result, taken over the expected life of the measure. (EU) [Source: EPBD].
The Deep Scenario or Deep Energy Scenario is defined as a scenario, in which state of the art in both new and existing buildings will become the norm in only ten years from now.
