The federal government is intensifying climate preparedness in existing buildings by integrating external shading systems into the "Federal Funding for Efficient Buildings – Individual Measures (BEG EM)". Measures such as roller shutters, external Venetian blinds, or awnings are now recognised as eligible for funding, alongside insulation work and the replacement of windows and doors. This development signals a strategic reorientation in the consideration of energy-saving renovation measures and underscores the relevance of the roller shutter and solar shading trade.
Simon Schmid, Chief Executive of the German Association for Roller Shutters + Solar Shading (Bundesverband Rollladen + Sonnenschutz e. V. – BVRS), views this decision positively. He stated that climate preparedness is no longer feasible without external solar shading, which is why the provision of funding by the federal government is to be seen as a consistent measure.
Although the funding conditions are clearly defined, their complexity often proves challenging for building owners and decision-makers. Schmid highlighted the specialised expertise of member companies, who are capable of coordinating technical planning, cost-effectiveness, and compliance with funding conditions. This includes advice on selecting suitable solar shading solutions, checking structural requirements, and ensuring eligibility for funding. Digital tools from manufacturers can provide support here by assisting with the assessment of funding opportunities and potential grants in advance.
Summer heat protection plays a central role in climate preparedness in residential buildings. A study by Guidehouse, commissioned by the European Solar Shading Organization, proves the significant benefits of dynamic solar shading systems. According to the study, electricity consumption for space cooling could be reduced by approximately 60 per cent by 2050, compared to a scenario without targeted expansion of such systems. This leads to an energy-efficient reduction of heat load in buildings.
Schmid explains the physical benefit, stating that external solar shading repels heat before it penetrates the interior of the building. This improves the habitability of living spaces during hot summer months and reduces the need for electricity-intensive air conditioning units. A forecast by the engineering firm Hauser, prepared within the framework of the Transparent Building Envelope Representation, supports this: professionally installed external solar shading can help ensure that a living space remains usable without air conditioning even in 2045. The roller shutter and solar shading trade is thus establishing itself as a key player in climate preparedness.
The BEG EM provides a basic grant rate of 15 per cent of eligible expenses. The minimum investment is EUR 300. Up to EUR 30,000 in eligible costs can be claimed annually per residential unit. If an individual renovation roadmap (iSFP) is in place and the measures are approved, this amount increases to up to EUR 60,000. Additionally, under certain conditions, a bonus of five per cent on the funding is possible.
