Pully and Givisiez, May 2025
ECCO2 is proud to support Cronos Finance in its strategy for energy-efficient and sustainable management of its real estate portfolio. Following a successful initial collaboration using ECCO2’s Building Intelligence technology, Cronos is taking the next step by expanding the use of the solution to a significant number of additional buildings.

Project Scope and Rollout
The initial pilot phase covered 21 buildings equipped with ECCO2’s Monitoring and Optimization solutions at the end of 2024, with 2 more buildings added early 2025. This deployment covers a total area of more than 40’800 m².
Pilot Results and Impact
Although the heating season was only partially completed, the results are already very promising. The average energy savings across the pilot portfolio are close to 11%, with one-third of the buildings achieving performance levels above 15%, meeting expectations.
At the end of the heating season, ECCO2 will calculate the absolute energy savings in kWh and the CO2 emission reductions. These figures will provide Cronos with a clear understanding of the environmental and financial impact of the initiative.
Benefits of ECCO2 Monitoring for Cronos
As with other clients, real-time monitoring proved to be a powerful tool for Cronos Finance, enabling fast and targeted action:
- Early detection of heating control issues: ECCO2 Monitoring revealed instances where heating systems were either manually controlled or incorrectly configured. Quick adjustments helped ensure proper functioning, improved comfort and optimized performance.
- Identification of malfunctions: The ECCO2 platform flagged cases of insufficient heat production and system shutdowns, leading to immediate coordination with building management and rapid technical intervention.
- Correction of hydraulic imbalances: Some heating loops showed uneven performance, causing inefficiencies. These were quickly corrected based on the data collected, improving heat distribution and reducing losses.
The data serves as a foundation for concrete next steps: from planning renovations and prioritizing interventions to dimensioning future energy systems with precision. This approach ensures that each decision is grounded in reality, not assumptions.
Scaling Up
Encouraged by the promising results, Cronos Finance has approved the extension of ECCO2 solutions to 31 additional buildings across 23 sites. The aim is to complete the rollout before the next heating season begins, in order to maximize optimization over the full cycle.
Mr. Olivier Juillard, Head of Asset Management at Cronos Finance, states:
“The solution implemented by ECCO2 enables us to optimize the heating system efficiency of the buildings within the Cronos Immo Fund. This initiative is an integral part of our strategy to reduce the carbon footprint of our real estate portfolio and meet the Federal Council’s 2050 targets. The interim results are aligned with the goals set by the ECCO2 teams, and following the success of the pilot deployment, we have decided to extend the solution to around thirty more buildings in the Cronos Immo Fund portfolio.“
This expansion reflects Cronos’s broader ESG ambitions and the trust placed in ECCO2 as a strategic partner in their decarbonization journey.
