Givisiez, February 2026
ECCO2 Solutions AG looks back on a highly successful 2025. Through its AI-driven Building Intelligence solution, tenants in optimized buildings saved 28,500 MWh of heating energy — translating directly into lower heating costs.
For property owners, these savings resulted in the prevention of 5,400 tons of CO₂ emissions. This corresponds to the average annual CO₂ footprint of approximately 1,350 people in Switzerland — equivalent to the emissions of a small village such as Forel (Lavaux, VD) or Wengen (BE).
These tangible and audited results continue to resonate strongly across the Swiss real estate industry. In 2025, ECCO2 expanded its footprint to more than 1,000 sites, covering over 24,000 apartments and 2.8 million m² of surface throughout Switzerland.
Strong Growth and Measurable Impact Across Switzerland
In 2025, ECCO2's NARA AI reduced heating energy consumption by 28,500 MWh (+44% vs. 2024) across its portfolio. To put this into perspective, this represents roughly half of the annual district heating energy delivered in the city of Thun (BE).
As the majority of optimized buildings still rely on fossil fuels for heating production, these energy savings prevented the emission of 5,400 tons of CO₂. ECCO2 is therefore making a measurable contribution to reducing Switzerland's overall energy consumption and carbon footprint — while improving operational efficiency for property owners.
AI and Machine Learning Driving Higher Performance
Compared to 2024, average energy savings increased from 20% to 22%, reflecting the continuous development of ECCO2's AI algorithms and the growing intelligence of the system.
The strength of the solution lies in a unique data foundation built over 10 years of heating optimization experience and enhanced by real-time data from more than 1,000 installations across all Swiss regions.
With live indoor temperature feedback from over 24,000 apartments, NARA AI continuously refines its optimization logic. The system dynamically adapts each property's heating strategy by incorporating building-specific characteristics as well as daily weather influences such as sun exposure, wind conditions, and temperature fluctuations.
This combination of scale, data depth, and real-time learning allows ECCO2 to deliver increasingly precise and property-specific optimization results.
Financial Strength Attracts Leading Real Estate Investors
ECCO2 closed its fourth consecutive year with a positive result, underlining the company's financial stability and long-term viability.
This consistent performance has encouraged large portfolio managers to expand their collaboration with ECCO2 and has attracted new institutional clients seeking a reliable, cash-flow-financed long-term partner.
As a result, ECCO2 achieved 30% growth in annual recurring revenue (ARR) in 2025 — demonstrating both strong market demand and increasing trust from leading property owners.
Outlook 2026 – Accelerating Growth
ECCO2 has already contracted optimization projects covering more than 2.8 million m², with additional large-scale pilot projects currently underway in major portfolios — confirming the expected performance results.
Today, 5 of the 10 largest residential property owners in Switzerland rely on ECCO2 to:
- Create measurable value for tenants
- Reduce portfolio-wide CO₂ emissions
- Strengthen long-term asset valuation
By further increasing penetration within existing client portfolios and continuing to win new mandates based on audited, fact-based performance results, ECCO2 expects accelerated growth in 2026.
To support this expansion, ECCO2 is currently hiring for several positions. Interested in joining our mission? Visit: ecco2.ch/about/careers
