Individual Renovation Roadmap (iSFP) in Renovation

Hello,

Lately, I have been looking into energy-efficient renovation and possible funding for my parents. In the process, I came across renovation to an efficiency house and the individual renovation plan. However, it is not entirely clear to me how and whether the whole thing can be combined.

My (perhaps naive) idea is that one can renovate to an efficiency house over several steps (and years) and then receive full funding for each step. For example, renovation to an efficiency house 55

[*]2022 facade insulation
[*]2022 basement ceiling insulation
[*]2023 overlay insulation, new roof, and photovoltaic system
[*]2024 new windows
[*]2024 controlled residential ventilation system
[*]2025 new heating

With all these measures, an efficiency house standard should be achievable. However, I currently find it hard to believe that it works the way I imagine, that is, receiving 45% for each step (40% for efficiency house 55 + 5% for iSFP). Funding would have to be paid out already in 2022, even though it is not yet clear that the corresponding standard will be reached. What if, for example, after the first two measures, no more money is available due to special circumstances? What if there is no funding available in 2025?

What is the individual renovation plan intended for if it does not work as described above? Maybe someone can explain this to me a bit more precisely using the example above.

Hello,

Lately, I have been looking into energy-efficient renovation and possible subsidies for my parents. In doing so, I came across the renovation to an efficiency house and the individual renovation plan. However, it was not entirely clear to me how and whether the whole thing is combinable.

My (perhaps naive) assumption is that one can renovate to an efficiency house in several steps (and years) and then receive full funding for each step.
For example, renovation to efficiency house 55

[*]2022 facade insulation
[*]2022 basement ceiling insulation
[*]2023 rafter insulation, new roof and photovoltaic system
[*]2024 new windows
[*]2024 controlled residential ventilation system
[*]2025 new heating system

With all these measures, an efficiency house standard should be achievable. But at the moment, I really can’t believe it works the way I imagine, meaning that one would get 45% for each step (40% for efficiency house 55 + 5% for iSFP). Funding should already be paid out in 2022 even though it’s not yet clear whether the corresponding standard will be reached. What if, for example, after the first two measures, there is no money left for special reasons? What if there is no funding in 2025?

What is the individual renovation plan intended for if it does not work as described above? Maybe someone can explain this more precisely using the example above.

The important thing for the iSFP bonus is renovation in at least 2 steps. For example, Step 1+2 as a single measure at BAFA with a 20% grant plus 5% iSFP bonus. Subsequently, the remaining steps via BEG residential buildings for the efficiency house with x% grant plus 5% iSFP bonus. Renovation to an efficiency house in one step would exclude the iSFP bonus.

It is best to get advice from an energy efficiency expert, who will then also create the individual renovation plan and calculate which efficiency house can be achieved.
