In the project, two multi-family houses of the South Tyrolean settlement in Bludenz are refurbished and the best solution in terms of energy and economy is determined. The building types of the settlement, which was built in 1943-62 with 397 residential units, are representative for large parts of the Austrian inventory. They are mostly preserved in their original condition and are heated exclusively by individual stoves.
Target
The aim is to determine the variant from a large number of possible renovation variants that leads to the lowest total costs for repayment of renovation costs, maintenance and repair costs, and energy costs. From the selected solutions, important conclusions will be drawn for the refurbishment of the other buildings in the settlement; to this end, a study will also be carried out on a possible local heating supply for the entire settlement.

This project is funded by the FFG.
The SüdSan project aims to facilitate the widespread implementation of refurbishments of older multi-family buildings that are expected to achieve the agreed climate targets after refurbishment. To this end, robust data on the additional costs of efficient refurbishments is being collected, with a focus on lifecycle costs rather than investment costs. In addition, methods for energy-economic optimization will be disseminated. The project is intended to serve as a practical example of how to reconcile climate protection and social compatibility.
