Vonovia Launches “1,000 Roofs” Program for Climate Protection
Bochum, August 15, 2019 – Vonovia SE (“Vonovia”) supports the energy revolution through the expansion of renewable energy in its real estate portfolio. In the next few years, Vonovia would like to install photovoltaic facilities on at least 1,000 roofs. The first modules have already been installed. Through the “1,000 roofs” program, Vonovia will produce around 10,000,000 kWh of solar power annually and feed it into the public grid. This reduces CO2-equivalent emissions in the portfolio by a projected figure of 4,300 tons per year.
“Climate change is one of the largest challenges of our time,” says Rolf Buch, Chief Executive Officer of Vonovia. “We support the goal of the German federal government to make the housing stock virtually climate neutral by 2050. With our ‘1,000 roofs’ program, we will make an important contribution to climate protection, particularly since a lot of our roofs remain unused.”
PV Potential is Determined Using 3D Simulation
The program spans a period of several years, the idea being to see it then evolve into a long-term expansion program. Three tranches are planned for 2019. The choice of roofs is based on a nationwide solar potential analysis, which takes into consideration GPS data on the buildings and factors such as roof inclination, orientation, shadows and solar radiation.
“We have created a 3D simulation for the majority of our roofs and initially identified more than 5,000 particularly well-suited roofs. These roofs, which have remained unused until now, offer vast potential for sustainable energy production. Since the beginning of the year, we carry out on-site visits to check the suitability of these buildings,” says Rafael Wilke, team leader in photovoltaics at Vonovia, explaining the process. The installation of PV plants is carried out in cooperation with regional installation partners.
The program is launched in Dresden and Munich. In the first tranche, photovoltaics will be installed in 210 buildings. The first plants (for example, at Burgenlandstrasse 21–27 in Dresden) have already been installed. Vonovia has identified 182 additional buildings for the second tranche of its “1,000 roofs” program. A third comparatively sized tranche will be pursued by the end of the year.
Plans for Decentralized Energy Supply of Neighborhoods
Solar electricity from the “1,000 roofs” program is primarily fed into the public grid. In the mid- to long-term, Vonovia is seeking to decentralize the energy supply to its own neighborhoods.
“The solar electricity generated on our roofs is not just to be fed into the grid, but is also designed to be used directly by our tenants, in their homes or at our charging stations,” says Buch. “Because we own neighborhoods, we have to design these accordingly and link them to the energy market. This is why we hope to see a marked reduction in the obstacles to landlord-to-tenant electricity models, which sadly remain manifold.” An amendment to the German Landlord-to-Tenant Electricity Act is expected in the fall.
Further information on sustainability management at Vonovia has been published in the latest Sustainability Report. With this report, which is available online, Vonovia is a top performer in the DAX family, according to a recent study by cometis AG. The consultancy company evaluated 131 sustainability reports from companies on the German selection indices DAX30, MDAX, SDAX and TecDAX. On the leading index, Vonovia reached first place, with 450 points, for “particularly detailed information on environmental issues.”
Vonovia’s Sustainability Report is only available online, which is also a contribution to the sustainable use of resources:
