Online value added calculator for energetic building refurbishment

Based on calculated average values for different building types and refurbishment measures, get an initial orientation for the value added from energy-efficient building refurbishment in your municipality or region.

The tool is offered by DIFU - German Institute for Urban Studies and IÖW - Institute for Ecological Economy Research.
The data and parameters on which the calculations are based were provided by the IÖW in cooperation with Ecofys. In a joint project of IÖW and Difu, these were expanded into the present value creation calculator. The development and support of the value creation calculator is funded within the framework of the National Climate Protection Initiative of the Federal Ministry for the Environment under the funding code 03KF0033A.
