Effectiveness of High Energy Efficiency to Minimize Energy Consumption for Residential Buildings in Egypt

Abstract

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.

Identifying Retrofit Technology to Improve Building Energy Performance: A Review

“…[07] And in another study the building sector is responsible for 62% of the total electricity consumption, 26% of the total energy consumption and 70% of CO2 emissions. [43] Public buildings energy consumption; in turn; has a great effect on total energy consumption. In Egypt public buildings represent 40% of the Egyptian building sector.…”

“…Financial Barriers: The construction developers in Egypt use the minimum expenses to construct a building without paying attention to energy performance measures. [43] This is especially evident in the difficulty of allocating appropriate funds related to the implementation of energy saving strategies and the costs that this entails. [44] Policies and Regulations: There is still unawareness of the importance of activating building codes to enhance building performance.…”

“…[5] Therefore, any solutions towards improving the energy efficiency in building sector plays an important role in reversing the negative impact on environmental and energy demand. [43] In developing countries like Egypt, no firm policies target the promotion of energy savings in buildings and their effect on climate change. [44] Building specific information: For many, it is the complexity of retrofit and financing that present a barrier to intervention and uptake.…”
