Green retrofitting of heritage buildings based on (3Ts) framework: An applied case study

Abstract

Diverse heritage architecture characterizes Port Said in Egypt, reflecting European and Arab influences. Suez Canal heritage villas comprise 25% of the total listed heritage buildings in the city. Thus, it is important to retrofit them, aligning with the Sustainable Development Goals (SDGs). By reviewing the previous literature related to the green retrofitting of heritage buildings, the (3Ts) framework can be considered a holistic framework that covers the latest trends due to its three components: targets, tools, and tasks, which help the success of the process through a holistic vision of supporting building information modeling (BIM) technologies and organizing stakeholders’ involvement. This paper aims to apply the (3Ts) framework to Suez Canal heritage villas in Port Said, Egypt. The applied study is based on how stakeholders perceive their input and decision-making, measuring the climate parameters, proposing several green retrofits, and integrating them into green scenarios. Evaluation of scenarios is conducted by utilizing the Design Builder simulation software. Additionally, the Skelion plugin calculates the photovoltaic system’s (PVs) energy generation. The results indicated that the total energy savings could reach approximately 12%-74% and nearly 10%-73% CO₂ emissions reduction without affecting heritage values.
