This work is centred on an ancient Italian church. Since 2011, a restoration plan has been undertaken by following sequential phases. The methodological approach to restoration was guided by environmental monitoring campaigns. In particular, two thermo-hygrometric campaigns were carried out during the warm months of the years 2015 and 2016. The first set of measurements was executed during the restoration of facades and roofs, making it possible to reach even areas that are usually difficult to access. The second set was performed to evaluate the indoor thermo-hygrometric conditions following the work of the previous year. This was intended to assess their differences in variability, the influence of the outdoor environment and any real and perceived improvement. Results demonstrate that thermal images helped in identifying both the heat sources causing thermal discomforts and the good thermal capacity of masonries. Concerning the heat index (HI), the church showed an improvement in the trend of malaise perceived by people during the second summer period (∼2°C lower than 2015). Finally, in the last microclimate monitoring, the roof structure no longer acted as an amplifier for daily temperature excursions.

通过修复工作评估古代教堂中的热变化:由热图像支持的微气候研究

这项工作的重点是一座古老的意大利教堂。自2011年以来,已按照以下连续阶段进行了恢复计划。恢复的方法学方法以环境监测运动为指导。尤其是在2015年和2016年的温暖月份进行了两次温湿运动。第一组测量是在修复外墙和屋顶的过程中进行的,甚至可以到达通常难以到达的区域。继上一年的工作后,进行了第二组评估室内温湿度条件。目的是评估它们的差异性,户外环境的影响以及任何实际和可感知的改善。结果表明,热图像有助于识别引起热不适的热源和良好的砌体热容。关于热量指数(HI),教会在第二个夏季期间(人们感觉比2015年低2°C)显示出人们感觉不适的趋势有所改善。最后,在最后的微气候监测中,屋顶结构不再充当日常温度漂移的放大器。
