Federal Ministry for Economic Affairs and Climate Protection

The building sector accounts for around 35 percent of end energy consumption and around one third of greenhouse gas emissions in Germany. This sector is therefore of central importance to the achievement of the Federal Government’s energy and climate policy objectives by 2050. In 2021, to strengthen ambitions in the building sector, the previous programmes in the areas of efficiency and renewable energies were restructured and bundled into the Federal Promotion for Efficient Buildings (BEG) programme, which has been optimised in terms of content and funding conditions.The funding is intended to support private, commercial investors, and building owners in the renovation of existing buildings. The goal is to reduce greenhouse gas emissions in the building sector by saving energy and to increase the share of renewable energies in the heating market.On behalf of the Federal Ministry for Economic Affairs and Climate Protection (BMWK), we are evaluating BEG funding of individual measures (BEG EM), residential buildings (BEG WG), and non-residential buildings (BEG NWG), for the funding period 2021 to 2025. Among other things, the BEG contribution to the climate and energy policy objectives (GHG emission reduction, energy saving), market acceptance of the supported measures, and macroeconomic effects are evaluated.The formative evaluation contributes to the success assessment of the BEG by the BMWK on the basis of the Federal Budget Code:
The key questions cover the following topics:
On the basis of the BMWK evaluation guide and DeGEval standards, indicators and methods for evaluating the funding programme are developed. The relevant data and information are then collected and analysed. The results will be evaluated and concrete conclusions and recommendations for action and proposals for further development of the programme derived.
As part of the evaluation, a random selection of beneficiaries is invited to take part in an online survey to provide additional information about the BEG and its implementation and impact.The invitation to participate in the survey is sent out by Prognos AG or the KfW Bankengruppe. The BMWK has requested participants complete the survey in support of the evaluation. The necessary documents (survey address, access key) will be sent by email or by post. Those who do not receive an invitation have not been selected to participate in the survey.

The current global economic order is faltering. What does this mean for Germany and the EU? We have developed various scenarios for the future global economy for the vbw.
The EU Commission commissioned Prognos, Idea Consult and the nova-Institute to research and promote the transition to a bioeconomy in the European Union.
What impact do global crises have on regional labour markets? The 15th issue of TerritoriALL magazine reports on the OVERLAP project carried out by Prognos.
The Single Market Programme promotes the EU internal market in order to strengthen it, standardise it and make it more competitive. Prognos was involved in the mid-term evaluation of the programme.
Prognos is supporting the North Rhine-Westphalian Ministry of the Environment in organising, implementing and establishing the world's first trade exhibition for the climate adaptation industry.
The Public Sector Loan Facility is an EU financial instrument to ensure a socially just transition to climate neutrality in the regions. Prognos and t33 srl evaluated the instrument.
German industry is heavily dependent on raw materials and intermediate products from abroad, especially from China. Prognos analysed supply chains and developed recommendations for action.
How can innovations be implemented in practice? This is where the BMBF's ‘Innovative University’ funding initiative comes in. Prognos and Fraunhofer ISI are evaluating the programme.
Specialists waste a lot of time on tiresome routine tasks. 3D planning tools or digital twins can help. Our analysis for the Fraunhofer IGD shows which professional groups benefit directly from their digital technologies.
Prognos has developed a tool for the Circular Cities and Regions Initiative (CCRI) that supports cities and regions in monitoring their circular economy activities.
Prognos is one of the oldest economic research centres in Europe. Founded at the University of Basel, Prognos experts have been conducting research for a wide range of clients from the public and private sectors since 1959 – politically independent, scientifically sound.
