Demo Site information:

Partners: CPEG / Estia

Location of the site: Wendt 35 1203 Geneva, Switzerland

Function of the building: Multi-family housing


  • Near zero energy refurbishment;
  • high performance envelope & renewable energy including energy storage;
  • deep monitoring for performance optimisation and smart readiness.

Reasons for the intervention: This building has been chosen because it includes many innovations (predictive maintenance, energy storage, community for self-consumption of on-site renewable energy).
High upscaling potential (550 building stock of the same owner potentially concerned)

Expected results:

  • 70% self-consumption of produced energy
  • Zero (or almost) performance gap
  • Reduction of maintenance costs
  • Real decrease of energy consumption: 60%

The raising of 2 stories will contribute into urban densification.
