Parametric Investigation of Double-Skin Facades with Building Integrated Active Solar Systems for the Energy Renovation of Buildings in the Mediterranean

Climate change is a critical issue that affects our planet, and the building sector is a significant contributor to global energy consumption and greenhouse gas emissions. As a result, there is an urgent need to renovate existing buildings to reduce energy consumption and improve their energy performance. The use of double skin facades integrated with active solar systems is a promising solution for energy-efficient retrofitting of buildings in Europe. This article parametrically explores the use of double skin facades with integrated solar active systems in Mediterranean countries, aiming to find the optimal solution for energy-efficient renovation of the building stock. The investigation is carried out using TRNSYS and Matlab software, and the results show that the use of double skin facades in multi-story existing buildings can be sustainable, as it saves energy without the need for additional insulation in the building. The study also highlights the importance of taking into account the local climate conditions and building characteristics when designing energy-efficient retrofitting solutions for existing buildings. The findings of this study can contribute to the development of effective policies and strategies for sustainable building renovation in Mediterranean countries.
