Abstract
Tensile materials are increasingly used in the building envelope as second-skin systems, despite a lack of investigation on their effects. In this work, a second-skin system integrating a tensile material as an outer layer has been adopted in the retrofit analysis of two of the most common building typologies in the Norwegian context. The simulations were carried out by implementing a custom control logic for the system, considering the outdoor air temperature and the global vertical irradiation on the façades. The proposed retrofit solution allowed for a primary energy saving of about 35%.
