Wrapping up the previous presentations, Ms. Fabbri noted that, though building renovation passports show great potential in alleviating two major barriers to renovation, namely the lack of awareness on potential benefits and a lack of a clear pathway of actions, actual implementation of the renovation measures is not guaranteed. She highlighted once again the purpose of the study being to quantify and show potential impacts of combinations of policies under specific conditions and based on a series of assumptions, in order to identify aspects that will have greatest impact and others which will need further investigation. Among the main outcomes of the preceding discussion is noted the need to better quantify and monetise indoor environmental quality.
In general, the impact shown is threefold and includes: triggered investments in energy efficiency, increase in the quality and depth of renovations, and earlier implementation of renovation measures. All 6 analysed policy packages are shown to be triggering energy and CO2 savings, the height of which depends on the overall conditions and context. However, impact will be limited unless coupled with financial, communication and training measures. When indoor environmental quality becomes an integral part of the building renovation passport, the potential to also improve comfort and well-being (health benefits) will also increase considerably.
