Building professionals everywhere have been presented with a real and serious challenge to drastically reduce CO2 emissions and improve building energy performance. In rising to this challenge, CIBSE has created the Energy Performance Group (EPG), a special interest group with a mission to:
Improve the energy performance of buildings by increasing awareness amongst all building professionals and supporting the implementation of relevant legislation aimed at reducing carbon emissions in buildings.
The Energy Performance Group (EPG) is CIBSE's largest Special Interest Group and has over 23,000 members from around the world.
Young Energy Performance Group (YEPG)
The YEPG has emerged into the light and is gathering members at pace! The YEPG is a sub-group of the Energy Performance Group which aims to introduce energy performance topics to those in their early career and students. Find out more.
