- Approved applicant for the ESZ subsidy programme being run by the Federal Ministry of Economics and Energy

The Challenge
Founded in 2014, EWUS GmbH offers a range of energy solutions, including energy system installation and optimization services. EWUS was looking for an intelligent software solution that would allow it to manage and comprehensively analyze heating system efficiency, including individual components (boilers, burners, pumps, heating circuits, etc.), in order to determine savings potential.
Benefits
- Energy management and energy efficiency: Monitoring of natural gas, heat, and electricity metering data, enabling system efficiency to be assessed.
- Savings: Automated diagnosis for the rapid and simple identification of inefficiencies. The measures recommended by this diagnosis produce energy savings of 5–8 %, without the need for investment in new systems technology.
- Data visualization: Dashboards that are customized to specific customer groups and which provide highly informative charts concerning consumption, usage, and system efficiency.
The Solution
- In addition to implementing the EnEffCo® monitoring solution, ÖKOTEC developed a custom measurement and KPI system that takes site-specific factors into account.
- A metering system was installed at each of the customer’s centralized heating facilities.
- These metering systems were then integrated into the EnEffCo® solution in order to track and monitor natural gas, heat, and electricity consumption.
- ÖKOTEC developed guidance documentation on energy saving measures, including measures for optimizing the efficiency small, medium, and large heating facilities.
Why EWUS relies on EnEffCo®
“EnEffCo® not only allows us to visualize the over 800 centralized heating systems operated by our customers; thanks to comprehensive analysis tools, we can show our customers opportunities for increasing efficiency.”
