ECCO2 is pleased to report the timely completion, and results of the first full year, of the deployment of ECCO2 Building Intelligence technology on an SFP-managed real estate portfolio which started in July 2023.
Swiss Finance & Property Group decided to equip one of their portfolios with ECCO2 Building Intelligence back in July 2023.
The ECCO2 team, working hand-in-hand with deployment partner Cablex, successfully implemented ECCO2’s heating control technology on 102 buildings representing a total area of around 200’000 m2. 2’200 indoor climate sensors were installed.
NARA AI, ECCO2’s AI-powered automatic heating control system, started optimizing the heating systems immediately after completion of each individual installation of the ECCO2 hardware.
As of the end of the first full year of operation, NARA reported portfolio-wide average savings of 20.3% exceeding the project goal both in savings and time frame.
Energy savings of 2’172 MWh, significantly surpassed the optimization service fees, resulting in net savings for tenants. CO2 emissions decreased by 410 tons, the equivalent of 4.65 million km of airline travel by a typical passenger.
Machine Learning is still ongoing and ECCO2 expects some incremental savings in the second year, both on the MWh of energy consumption and on the CO2 emissions.
During the project, the average indoor temperature was reduced from 22.8°C to 21.7°C while maintaining the tenants’ comfort. Initial indoor temperature (measured at the beginning of each project) is displayed in the left graph. Each blue rectangle represents one heating circuit.
The statistical distribution of before/after indoor temperature is depicted in the right graph. In red before and in green after optimization, clearly demonstrating the shift towards more appropriate temperatures for everyone’s benefit.
The graphs below show how NARA AI took control of indoor temperature in a sample building over a 3-month period, gradually suppressing overheating, while exploiting free energy from solar gains to achieve constant indoor temperature by proactively suppressing overheating peaks which would have occurred on very sunny days.
The top graph shows the average indoor temperature and its evolution through the first phase of optimization, whereas the lower graph displays the changing weather conditions during the same period.
And finally, our ECCO2 Consulting department is currently working on the agreed-upon value-added services to support SFP’s plan to identify, prioritize and progressively replace heating systems that use fossil fuels.
The data generated by ECCO2 Building Intelligence will prove invaluable in this process, allowing optimum financial resource allocation for maximum impact.
Congratulations to SFP and the ECCO2 / Cablex teams for another successful full-portfolio deployment.
