Zukunft ERDGAS presents new study on CO2 reductions in building stock

Essen. A new study by Zukunft ERDGAS shows how CO2 emissions in rented apartment buildings can be drastically reduced: “Climate protection is possible and affordable if we take the right measures,” Dr. Timm Kehler, Chairman of Zukunft ERDGAS e. V., explained at the presentation of the study at the E-world energy trade fair in Essen. Around two thirds of CO2 emissions from existing rented apartment blocks could be avoided by 2050 compared to 1990 according to the study.

The study “Refurbishment roadmap for apartment blocks: how can efficient climate protection be successfully integrated into the refurbishment of the building stock?” is based on representative case studies that were extrapolated to provide an overall result. “We drew up 724 individual refurbishment roadmaps for buildings, and based on this very complex – and thus realistic – basis, we calculated the potential savings, which are not only positive, but also realistic,” Kehler said. He presented the study in Essen together with the WINGAS Managing Director Ludwig Möhring, who is also Deputy Chair of the Advisory Board of Zukunft Erdgas, and Dr. Håvard Nymoen, Managing Director of consultants Nymoen Strategieberatung. “Every refurbishment road map needs a financial roadmap too. Thus, we only considered measures that tenants and landlords can actually afford.”

Key factor: efficient heating
The study shows that efficient heating is the most important factor of climate protection in the building stock. Three-quarters of refurbishment plans begin with measures related to heat generation, i.e. improved heating technology or changing to a more favorable fuel. In this sector, substantial savings in CO2 can be made with relatively little cost or effort. And heat generation will be the most important factor up until 2050, for 60 percent of efforts to reduce emissions can be made in this sector – 20 percent each from building insulation and window replacements. “Energy-efficient refurbishments shouldn’t be confused with facade insulation. A refurbishment roadmap always involves a sequence of sensible and financially viable individual measures. If you begin by replacing your heating system, you get good results in terms of reduced emissions, and it pays off quickly,” Kehler underline.

Zukunft ERDGAS is an initiative of the German natural gas industry. It aims to promote the potential of natural gas as an energy carrier and provides information on the opportunities and possibilities that natural gas offers for Germany’s energy transition and the energy mix of the future. Zukunft ERDGAS is funded by leading companies in the natural gas industry such as importers, regional suppliers and municipal utilities. The heating equipment industry and the heating trade also support the initiative as partners.
