Effectiveness of high energy efficiency to minimize energy consumption for residential buildings in egypt

Abstract EN

The effects of global warming and climate change have become a critical issue in our world where the average air temperature rises to 2 ° C that leads to sea-level rise, seasonal disturbances storms, floods, and massive fires.

[1]
Increasing energy demand during the cooling period has become an essential issue in Egypt.

Solutions can be applied to develop the building envelope for existing buildings by implementing a different technique that can enhance energy performance and improve indoor thermal comfort.

The roof is the one of building envelope components which can reduce energy consumption and enhance indoor thermal comfort in buildings.

The scope of this paper deals with evaluating the energy performance of residential buildings using different roof techniques: cool roof, green roof, isolated roof and integrated roof with Phase Change Materials (PCM) in Egypt that can lead to different solution of roof to achieve ideal energy performances.

The assessment is carried out by using the Design Builder Software which can be able to calculate the monthly energy consumption.
