Implementation Stories

Ennobox by E-nno Switzerland SA
Implemented by Edmond de Rothschild in Many cities (Switzerland) in 2021

The Ennobox Solution has been deployed since 2021 on Edmond de Rothschild REIM's property portfolio in Switzerland. The company was looking for an energy monitoring, analysis and optimisation system that would reduce the environmental impact of its buildings while cutting costs for tenants. Given the diversity of the technical installations (gas, oil, heat pumps, etc.) and the geographical distribution of the buildings, the client wanted a global, centralised solution to facilitate the management of its assets. Ennobox's stand-alone intelligent optimisation technology now makes it possible to acquire, use and analyse data to optimise the operation of all types of technical installations, without the need for massive deployment of sensors in buildings. This technology also centralises data in a portal to support decision-making during modernisation and renovation projects.


Since 2021, the hundred or so buildings equipped between Geneva and Zurich have saved 1 250 000 kWh and avoided the consumption of 320 000 kgCO2.


The environmental benefits

  • 1 EnnoBox per building can gather up to 210 000 data points/year
  • 1 EnnoBox is setup in less than 5 hours, which is 2 times more effective to competitive solutions
  • Existing buildings average of 13 MWh savings consumption/year/building
  • Existing buildings average of 3 tCO2 emission avoided in one year (depending of energetic source)

The Financial benefits

  • Building average payback time of 3 years
  • Building average annual financial savings : -2.5 kCHF
