## Optimizing Plant Operation at a Passive House School

EA Systems conducted intensive monitoring of the complex plant system at Sonthofen secondary school for two years. Insights into its operating strategy enabled a significant increase in the passive house school’s energy efficiency and a considerable reduction in operating costs. The project demonstrates the importance of validated checks and tests after energy supply systems are commissioned.

## Our Services

- Extension, maintenance, and operation of the EnOB-compliant monitoring system for two years of measurement data acquisition
- Verification of the energy savings targets set before renovation
- Assessment of the plant and control system, including review of optimization measures

## Our Results

- Significant, lasting improvement in energy system efficiency and reduction in running costs, especially at low temperatures and in heat pump operation
- Optimization proposals and action plans to improve plant operation and controls
- Quantification of achieved energy savings compared with the pre-renovation condition
