Conservation compatible passive retrofit solutions

This report presents a compilation of passive retrofit solutions that can be applied to historic buildings subjected to conservation requirements. The aim is to gather the most common strategies and provide a general overview of their key characteristics, enabling a meaningful comparison and supporting the selection of the most appropriate solutions for different building contexts. Each solution is assessed based on a set of parameters, including general information, technical specifications, and aspects related to sustainability and lifecycle performance. The collected solutions are presented in summary tables within this report, while an Excel version is available in the annex to facilitate filtering and sorting. In total, the report includes 80 insulation retrofit solutions and 76 window retrofit variants.
In addition, an assessment of collected retrofit solutions was made for each building typology defined in Deliverable 1.2. This selection was carried out through a collaborative workshop with project partners from FuturHist. The choice of solutions was based on several criteria, including building construction characteristics, local regulations, and regional retrofit approaches. The outcome of this process is a list identifying retrofit solutions that are most appropriate for the specific needs and constraints of each typology.
