Sviluppo di una piattaforma computazionale interattiva per la simulazione di involucri responsivi ad alte prestazioni in diversi scenari climatici tipici e futuri

Many researchers have recently developed new responsive technologies to improve the interaction between the mutable external environment and the building. These systems can react to external stimuli – e.g., outdoor temperature, solar radiation, etc. – changing their properties – solar, thermal, geometrical, etc. – to reduce the energy demand and the users’ discomfort. Despite a large number of studies propose new responsive technologies, these devices are still not widespread and the reason of this mismatch between theoretical technological studies and practical applications is probably due to a lack of simple and easy-to-use energy analysis tools. The intrinsic complexity of many of these systems requires a specific knowledge and – depending on the specific technology – could require also additional external algorithms to run energy analyses. The aim of this work is to provide an interactive tool that allows to simplify the modelling and simulation phase, giving as final output a reliable comparison between traditional and responsive technologies. From a technical point of view, the platform is based on EnergyPlus as simulation engine, Python as simulation and file manager, and Grasshopper as graphical interface. The file management, the modelling and the simulation are completely automated; hence, the users work only on Grasshopper simply inputting through pop-up menus the key information (context, technology, control strategy). The users can select between different responsive technologies and, considering their dependance on the weather conditions, the users can test them in 25 different European cities. Similarly, three different climate scenarios (current, 2050, 2080) can be selected to evaluate if the responsiveness of these systems can be helpful also in future scenarios to improve the building resilience to climate change. This paper describes the structure of the platform developed and tests its reliability and potential on an electrochromic application
