Phase 1 – On-site measurements in the existing building

Since the 2024/25 heating season, the MBI building has been fitted with sensor technology.

Goal: Capture and analyze heat flows on-site and validate an energy simulation model.

Phase 2 – Comparison of minimally invasive radiator measures

From the 2025/26 heating season, we will trial the following across all floors:

• Comparing different radiator thermostat types (self-learning vs. remotely controlled)
• Analyzing the impact of radiator fans on heating demand.
• Deploying wall-mounted thermostats to record temperature, humidity and CO₂, in order to clarify responses to both thermostat and fan controls,

Goal: Develop optimized control strategies to quantify the energy-saving potential of these targeted measures.

Phase 3 – Integration of renewable local heat

In parallel, in preparation for the 2026/27 heating season, we are designing a supply scheme combining renewable local heat from solar thermal, geothermal sources and waste heat recovered from the CRA building.

Next, we will test the building’s compatibility with lower supply-water temperatures and integrate a control system that can switch in existing district heating when required.

Goal: Assess CO₂ savings and thermal load shifting under real operational conditions.
