Progress on test sites
The project is proceeding with the characterization of the performance of the retrofit solutions developed or identified in the context of WP4.
As regards the two formulations of insulating plaster developed by the partner Vimark, an assessment of their hygrothermal performance is being carried out using two different approaches. A hygrothermal characterization at material level is being carried out in the Hygrothermal Testing Lab at Eurac Research, where various properties are measured, such as thermal conductivity, vapor permeability and water absorption by partial immersion. On the other hand, at the FACT facility on CEA site, an historic-like wall has been built in plain bricks, including an oak-wood window with single glazing. Two different plaster formulations have been applied as internal insulation, with the aim of studying thermal performance in real conditions. This will allow also to test one of the steps of the renovation protocol developed in Task 4.3, namely the assessment of the airtightness of the window in situ. In particular, the window will be subjected to comparative tests by CEREMA before and after renovation.
In terms of photovoltaics, different technologies have been selected in Task 4.5, being suitable for application on historic buildings, and are tested at the CEA PV-test-roof facility, with a focus on terracotta and red modules and tiles. PV performance will be evaluated including thermal behavior.
