Renovations, heritage and volumes
For your renovation plans in Aarau, federal building register figures are vital. With 467 buildings under heritage protection, it is crucial to contact the municipality early to address permit requirements. The median house volume is 800 m3, which serves as a key indicator for scaling insulation or heating upgrades. Please note that data coverage regarding volume is partial, as only 20 houses were measured according to the SIA 416 standard. We recommend verifying the precise dimensions of your specific property before starting any works to ensure your renovation budget remains accurate and effective for your project.

Frequently asked questions
Do I need a permit for solar panels in Aarau?
A suitably integrated roof system often only needs notification. However, always check the specific requirements for your building, especially if it is a heritage site, as rules can vary.
How can I benefit from the Pronovo one-off remuneration?
The federal one-off remuneration lowers the cost of small systems. You must submit an application to Pronovo after checking the technical criteria of your installed photovoltaic system.
Is profitability guaranteed with photovoltaics?
Profitability depends mainly on how much power you use on site. The more you use your own energy for daily needs, the faster your investment becomes profitable over the long term.
