„Private property investors are often initially looking for a rough cost estimate in order to assess whether to seek bespoke professional assistance. The tool that is being developed in RentalCal could offer low-level access to the relevant information, in particular for WEGs [residential property owner associations] with their unique decision making structures. At present, any advice or tools that are available free of charge are dominated by the commercial interest of those that provide them. Therefore, we very much welcome the approach offered by this new tool.“

„We believe RentalCal is suited to enhance the quality of energy performance of buildings consulting in Germany and Europe, which is good news to customers.”

„We see the project RentalCal as a valuable contribution towards an environmentally friendly building sector by translating the positive effects of energy efficient and sustainable construction into real values and financially feasible investments for the real estate industry.“
