Energy for large areas

DIY retailers and home improvement stores are among the commercial properties with particularly high electricity consumption. Lighting, ventilation, heating, and large sales areas continuously drive up energy requirements. At the same time, operators and tenants are under pressure to reduce emissions and ensure predictable energy costs in the long term. At its Stuttgart-Untertürkheim location, BAUHAUS, together with Nanz Handelsimmobilien and GIGA.GREEN, is demonstrating how photovoltaics can help meet these challenges.

Starting point: Sustainability as a location factor

The owner, Nanz Handelsimmobilien, has been relying on solar energy for years to future-proof its properties. With BAUHAUS in Stuttgart-Untertürkheim, another large DIY retailer has now been solarized—as part of a clear strategy to transform roof space into valuable energy sources and increase attractiveness for tenants.

Solution: Photovoltaics on the roof of the BAUHAUS site

A high-performance photovoltaic system was installed on the roof of the BAUHAUS site in Untertürkheim. It produces renewable energy directly on site and delivers tangible benefits for both owners and tenants. Key data for the project:

• 589.05 kWp installed PV capacity
• 1,386 solar modules installed
• 5,654 tons of CO₂ reduction in total

Results: Economic efficiency and sustainability combined

The photovoltaic system allows the DIY retailer to plan its electricity costs for the long term using the onsite PPA model. At the same time, the project significantly reduces the site's emissions and increases the property value through a future-proof energy supply.

Customer feedback

„DIY retailers require large areas of space—and these areas offer ideal conditions for photovoltaics. This allows us to transform roof space into a valuable source of energy, reduce operating costs for our tenants, and increase the value of our properties at the same time.“

Florian Nanz, Nanz Handelsimmobilien GmbH

„The photovoltaic system enables us to secure stable electricity prices in the long term, reduce emissions at our Stuttgart-Untertürkheim site, and at the same time strengthen our customers' confidence in our commitment to sustainability.“

Giancarlo Posella, BAUHAUS Fachcentrum Stuttgart-Untertürkheim

Conclusion: Photovoltaics as a model for retail

The example in Stuttgart-Untertürkheim shows how photovoltaics can turn retail properties into sustainable and economically stable locations. While owners future-proof their portfolios, tenants benefit directly from predictable energy costs and a better carbon footprint. Photovoltaics is therefore key to strengthening the competitiveness of retail properties.
