Actual energy savings of more than 1000 renovated buildings in Geneva

Pierre Hollmuller Head of Systèmes Energétiques Group

Abstract
This study quantifies the annual energy-related retrofit rate of the Geneva building stock (1.7%), based on data concerning the delivered construction permits over the 2010 – 2018 period. By cross-cutting with final energy demand before and after retrofit, we derive an energy- efficient retrofit rate (0.6% for an improvement of 1 class at least, 0.2% for 2 classes at least). Results are analysed as a function of the construction period, as well as of the energy demand before retrofit.
