Nowadays, energy retrofit interventions on the existing building stock are of paramount importance towards energy consumption and emissions reductions in the construction sector. Such interventions are also crucial in the view of increasing cities resilience with respect to the intensification of frequent extreme weather events, such as cold spells and heatwaves. Indeed, a wide portion of our cities is dated and lacking with respect to performances. These are the motivations behind the proposed sustainable approach, which deals with the environmental perspective, but also with social and economic ones, by proposing the retrofit of the Public Residential Building stock (Edilizia Residenziale Pubblica, ERP). The objective is to improve the energy performance of ERP stock by means of construction materials coming from local km0 agricultural waste and by-products. The research was conducted by means of in field and numerical analyses of the energy performances of a relevant case study building. Different layers of bio-based, recycled construction materials for the envelope were tested with respect to their efficacy in improving the energy performance of a case study building. The results demonstrate that the most performing envelope solutions and their combination are able to reduce up to 36% of the yearly energy consumption for heating.

一种可持续的公共房屋建筑改造方法：能源建筑实验与数值分析

如今，对现有建筑存量进行能源改造干预对于建筑行业的能源消耗和减排至关重要。鉴于增强城市应对频繁的极端天气事件（如冷风和热浪）的应变能力，这些干预措施也至关重要。确实，我们城市中有很大一部分是过时的，缺乏表演。这些是提议的可持续方法的动机，该方法通过提出公共住宅建筑存量的改造（Edilizia Residenziale Pubblica，ERP）来处理环境问题，同时也涉及社会和经济问题。目的是通过来自当地km0农业废弃物和副产品的建筑材料来提高ERP库存的能源绩效。该研究是通过对相关案例研究建筑物的能源性能进行现场和数值分析来进行的。测试了信封的不同层的生物基再生建筑材料在改善案例研究建筑的能源性能方面的功效。结果表明，性能最高的封套解决方案及其组合可以减少多达36％的年度供暖能耗。测试了用于信封的再生建筑材料在改善案例研究建筑的能源性能方面的功效。结果表明，性能最佳的封套解决方案及其组合可以减少多达36％的年度供暖能耗。测试了用于信封的再生建筑材料在改善案例研究建筑的能源性能方面的功效。结果表明，性能最高的封套解决方案及其组合可以减少多达36％的年度供暖能耗。
