86% less energy consumption on 3,000 m² commercial space

The property was built in the early 1990s. Following a thorough analysis of its current energy performance, the non-residential building corresponds approximately to energy efficiency class D after conversion using the BVI method. The owners want to determine whether and which optimizations are appropriate to make their property future-proof. The energy refurbishment concept for the approximately 3,000 m² commercial property includes extensive energy-efficient upgrades. The plan is to completely modernize the building's technology, including lighting, replacing windows with triple-glazed units across over 500 m² of window area, installing a modern heat pump, and an intelligent heating and ventilation system, complemented by insulation of the roof, basement, and facade. A photovoltaic system with approximately 250 m² of modules is intended to support self-consumption of renewable energy and reduce grid dependency.

The implementation of these measures is expected to reduce final energy consumption by 86 percent. Demand is to be reduced from the current level of approximately 500,000 kWh per year to approximately 70,000 kWh – a saving that will have a significant impact on operating costs. At the same time, a significant reduction in CO₂ emissions is forecast – from approximately 137,000 kg CO₂ per year to just under 40,000 kg CO₂ – a reduction of almost 70 percent.

With this energy-efficient refurbishment concept, the owners are aiming to achieve an improvement to approximately energy efficiency class A (converted according to the BVI method) while simultaneously meeting important ESG criteria. The project demonstrates how strategic planning can achieve significant ecological improvements and long-term operating cost savings. Furthermore, the project is receiving funding of almost €400,000 from the Federal Funding for Energy-Efficient Buildings (BEG EM) – a significant contribution to the economically viable implementation of the measures.
