The Monetary Benefits of Ambitious Building Energy Policies report offers a first attempt to quantify the global and regional cost implications of ambitious scenarios for implementing large-scale energy efficiency improvements in buildings.
The current study is a continuation of the Best-practices scenario analysis by the Global Buildings Performance Network (GBPN),and is also based on the 3CSEP HEB model (Center for Climate Change and Sustainable Energy Policy High Efficiency Buildings Model), which was extended to include the Cost analysis module. As with the previous study, this report is focused on the four key regions, including both developed regions (EU-27, USA) and emerging economies (China, India). The global costs and benefits for the two outlined scenarios are calculated based on the aggregation of the results for the 11 regions, defined in the Global Energy Assessment (Ürge-Vorsatz et al. 2011).
The aim of the presented study was to analyse the costs and benefits of selected building energy consumption scenarios developed by the aforementioned research on behalf of GBPN. To fulfill this aim, two objectives were set:
1. to calculate the total cumulative additional investments needed by 2050 for the Moderate and Deep efficiency scenarios, and
2. to calculate the total cumulative energy cost savings by 2050 for the Moderate and Deep efficiency scenarios.
In summary, the results show that in the long term, unlike the Moderate efficiency scenario, the Deep efficiency scenario is cost-effective for all four major regions, as well as for the world. The results also show that for all analysed regions and the world the Deep efficiency scenario has higher energy cost savings and higher cost-effectiveness (i.e. the larger difference between energy cost savings and investment costs) than the Moderate efficiency scenario.
This report was commissioned by the GBPN to the Central European University’s Center for Climate Change and Sustainable Energy Policy (3CSEP), as well as to the Advanced Building and Urban Design (ABUD).
