Summary: This study proposes a dynamic envelope based on the double-skin facade (DSF) technology as a retrofit measure for an existing building office in a Mediterranean climate. The proposed facade's responsiveness is achieved through controlled opening of windowed components and a shading system with dynamic activation controlled by temperature. Compared to the current state, the energy consumption for thermal load can be reduced by 17.8% to 37% and for cooling load by 9% to 3%, resulting in a total primary energy saving of 20%.

Summary: The importance of sustainable building systems design practices in improving the performance of building envelope components has been emphasized by the green building movement. Fenestration, which accounts for the majority of heat transfer across the building envelope, plays a crucial role in improving the thermal performance of glazing units. This literature review focuses on identifying research opportunities for fenestration-related technologies in cold climate zones, including automated shading systems, glazing films and coating, and smart glazing systems. The review provides an overview of these technologies, their evaluation methodologies, and the energy savings achieved through their implementation. It also highlights the need for future research to improve energy performance verification procedures and address gaps in the cold climate applicability of fenestration technologies.

Summary: The European Union has developed policies to accelerate the retrofitting of existing buildings in order to achieve a decarbonised building stock by 2050. However, retrofitting faces barriers such as low financial availability, user awareness, regulatory uncertainty, and supply chain fragmentation. This research proposes a novel step-by-step guideline that combines Building Information Modelling (BIM) with Business Process Modelling (BPM) to overcome these barriers. The proposed BIM-BPM workflow was demonstrated in a residential pilot building in Ireland.

Summary: In developed countries, a large amount of existing buildings will make up the building stock in 2050, which necessitates the consideration of energy efficiency in both new and old structures. The use of rehabilitation and energy efficiency measures can lead to a significant reduction in energy consumption for climate control. However, the high computational cost of detailed thermal behavior models hinders their practical application. This paper proposes the Response Surface Methodology (RSM) as an innovative approach to simplify energy saving calculations and validates it through a case study of a single-family house model in different climates.
