在温暖气候中建造的建筑物在夏季会受到严重过热问题的影响，这对人们的舒适和健康产生了负面影响。由于这些原因，许多用户被迫安装冷却系统，导致成本增加，消耗和对环境的意义impactions.This研究给出了一个有效的方法来监测过热问题的建筑物位于地中海气候，不使用冷却系统，但只是一个准确的设计的信封。主要的挑战是证明根据UNI EN ISO 52016每小时监测内部工作温度（TOP）能够明确定义建筑物的性能，同时考虑到围护结构的特性。这一参数的优化可以使建筑达到高水平的内部舒适度，确保设计师确定组成围护结构的建筑材料的最佳选择。TOP趋势在位于温暖的地中海气候的单住宅建筑模型上进行了一整年的测试，考虑不同的外墙结构，结果表明，最佳的解决方案的特点是存在双层凝灰岩，最后，本研究表明，一旦优化了围护结构，仅使用机械通风系统更容易达到良好的内部工作温度值。
Buildings built in warm climates are affected by severe overheating problems in summer, which negatively affects people's comfort and health. For these reasons, many users are forced to install cooling systems, leading to an increase in costs, consumption and a meaning impact on the environment.This study gives a valid method to monitor the overheating problems in buildings located in Mediterranean climates, without the use of cooling systems, but just with an accurate design of the envelope. The main challenge is to demonstrate that the hourly monitoring of the internal operative temperature (TOP), in accordance with the UNI EN ISO 52016, is able of defining univocally the performances of the building, taking into consideration the characteristics of the envelope. The optimization of this parameter permits to reach high level of internal comfort in a building, ensuring the designer to identify the best choice of building materials that compose the envelope.The TOP trends, for a whole year, are tested on a single-residential building model located in a warm Mediterranean climate, considering different configurations of the external walls.The results put in evidence that the best solutions are characterized by the presence of the double layer of tuff, with a very massive layer in the internal side and resistive layer outside.At the end, this study demonstrates that once optimized the envelope, it is easier to reach good values of internal operative temperature with the only use of a mechanical ventilation system.
