PropTech Spotlight Startup Story: ECCO2 – 20% less heating energy without refurbishment
PropTech Spotlight by SwissPropTech features ECCO2 in a Startup Story: sensors, data and NARA AI cut heating energy consumption by around 20% on average – without structural work. In use at over 1'000 sites and in more than 24'000 apartments, with 28'500 MWh saved in 2025.
SwissPropTech has profiled ECCO2 in its Spotlight Startup Story (published in German).
What is SwissPropTech?
SwissPropTech is Switzerland's leading network for real estate innovation. It connects start-ups, real estate companies, investors, operators and technology partners in an open ecosystem.
Its mission in one sentence: innovation knows no borders – SwissPropTech wants to make sure the real estate industry does not miss the crucial moment to transform, and brings its members together with inspiring people and innovations from all over the world.
That makes the network more than a platform: it curates, validates and gives visibility to the technologies that actually work in the Swiss market – accelerating digitalisation and decarbonisation across the existing building stock.
Why the story matters for ECCO2
The path to climate-neutral buildings is decided in daily operation, not on the drawing board. That is exactly where ECCO2 works – and exactly the perspective SwissPropTech carries into the industry: to owners, portfolio managers and investors who decide today on refurbishment budgets, ESG targets and operating costs.
For ECCO2 the feature therefore means three things: independent confirmation of impact by a network close to the industry, access to the decision-makers where scaling happens – and evidence that operational optimisation is taken seriously as an alternative to structural refurbishment alone.
"The technology optimises today's operation and delivers the data for tomorrow's decisions." — Stefan Keiser, ECCO2
