The energy-efficient refurbishment of buildings is expensive, time-consuming - and often inefficient. In view of ambitious climate targets and limited financial resources, the housing industry is now calling for a radical change of course: away from costly facade insulation and towards intelligent, technology-supported CO₂ reduction in the boiler room. This is the clear appeal made by Axel Gedaschko, President of the GdW, and Dr. Thomas Hain, Managing Director of Nassauische Heimstätte | Wohnstadt, in an interview on the occasion of the upcoming “Initiative Wohnen.2050” (IW.2050) conference.

On April 26, 2025, we will be celebrating Renewable Energy Day - an occasion to reflect on the significant progress made in the expansion of renewable energy worldwide.

The recently published study by Aurora Energy Research on behalf of EnBW is causing a debate. Its aim is to make the energy transition more cost-efficient – with potential savings of up to 700 billion euros by 2045. The focus is on a reduced expansion of the electricity infrastructure, fewer electrolysers, more gas-fired power plants (powered by blue hydrogen) and a slower ramp-up of battery storage systems.

Our headquarters: The city of Mannheim is one of the most progressive municipalities in Germany when it comes to the municipal heating and energy transition. The city aims to be climate-neutral by 2035 at the latest - an ambitious goal that can only be achieved with integrated concepts, technological diversity and local responsibility.

The European Commission has presented a comprehensive “omnibus package” aimed at simplifying existing sustainability regulations. The aim is to reduce bureaucracy, increase the efficiency and impact of ESG instruments and reduce the burden on small and medium-sized enterprises (SMEs) and those responsible for ESG in companies in particular.

District heating plays an important but not problem-free role in the context of the heating transition. In terms of cost-effectiveness and sustainability, it lies between heat pumps and gas heating systems, but has specific challenges.

The pilot projects for our PAUL Net Zero product have been successfully launched. On this page, we regularly provide an insight into the implementation of PAUL Net Zero

The building sector plays a key role in reducing greenhouse gas emissions, as buildings account for around 36% of final energy consumption in Germany. However, the Federal Environment Agency's “Greenhouse gas projections 2025 - compact results” show that Emissions in the building sector continue to far exceed climate targets.

Friedrich Merz and Lars Klingbeil gave a clear and correct message at the Bundestag session on March 18: “Money has never solved all problems,” said Merz. Klingbeil said that Germany needed to become “more efficient, more targeted and more professional everywhere”.
