Promoting green retrofitting to enhance energy efficiency of residential buildings in egypt

This paper attempts to formulate a guideline to the actions required to promote green retrofitting in the Egyptian residential sector. Buildings play a primary role in any national economy, yet they also contribute significantly to global energy consumption. The existing building stock remains a challenging and crucial part of the equation. Achieving sustainability in the existing building stock is particularly challenging in a country like Egypt, as it faced a severe power crisis in the past few years. The residential sector, in particular, is responsible for around 51% of the country’s power consumption. The paper starts by introducing the concept of green retrofitting and highlighting the benefits of adopting such an approach. International case studies are reviewed to highlight possible energy savings benefits of applying green retrofitting. A local case study is analysed using the hourly analysis program revealing considerable induced energy savings. The paper concludes by recommending the actions required to promote green retrofitting in the Egyptian market while addressing the roles and responsibilities of the different stakeholders, building upon a more holistic approach to achieving sustainability in the building sector in the long run. © 2020, Cairo University.
