The main issue lies in oversizing, which stems from an outdated process: sizing the substation based on theoretical values from the CECB (Swiss Energy Performance Certificate). This approach results in an overly powerful installation, leading to excessive investment and service costs. This waste recurs annually, adding to the significant expenses incurred during the system’s implementation – amounting to tens of thousands of francs per building.
A Simple and Proven Solution
The key is to start by fine-tuning the heating system and collecting real operational data to accurately size the system. ECCO2 Solutions SA, a Swiss company and leader in predictive heating management, supports you in 4 steps:
- Equipping your buildings: We install the ECCO2 Building Intelligence solution at least one year before replacing the heating system.
- Energy demand reduction: ECCO2 Building Intelligence reduces energy demand by 10 to 20%, while improving indoor comfort through AI-driven predictive control. Real-time energy consumption data is correlated with weather conditions and measured indoor temperatures.
- Precise system sizing: At the end of the optimization process, ECCO2 Consulting analyzes the collected data and collaborates with your contractor to precisely size the connection.
- Optimized commissioning of DH: When the DH system is commissioned, ECCO2 Consulting validates the operating parameters and activates the “WATTime” technology. This system optimizes heating based on future weather forecasts, smoothing power peaks to ensure optimal comfort while respecting your subscription framework.
The Results:
Reduced investment costs: Substation power requirements are reduced by 20 to 50%.
Lower recurring subscription fees.
Comfort control and automated supervision: Both before and after transitioning to DH.
Not sure if you need it?
These data points from a regional district heating provider may help:


Chart 1: On average, customers pay 100% more for subscriptions than necessary.
Chart 2: Subscription fees typically represent one-third of the monthly subscription invoice. With an average oversizing of 100%, the monthly bill is 20% higher than required.
ECCO2 Building Intelligence already manages over 2,500,000 m². Deployment is fast, cost-effective, subsidized, and results are guaranteed.
