Building envelope optimization technique to increase energy efficiency of office building in Egypt

Sustainable design is a design strategy that aims to improve environmental quality as well as the quality of a building’s internal atmosphere by limiting negative consequences on the structure and the surrounding environment. Several new building envelope technologies and concepts have been presented as solutions for enhancing indoor comfort and lowering environmental impact during building life cycles. In Egypt, the high sensitivity to temperature fluctuations resulted in an increase in power usage to meet the necessary cooling loads. Energy simulations are a common way to improve a building’s energy efficiency. Design Builder program with the Energy Plus simulation engine was used for energy analysis of the building. This was confirmed by comparing the energy efficiency performance of selected case studies of buildings with and without a sustainable development approach. In two parametric series, an existing prototype of a residential unit module will be utilized to evaluate energy performance, co2 emission and thermal comfort. It has been discovered that a building envelope with a variety of characteristics may provide the inhabitants with the highest level of residential comfort. In comparison to similar-sized structures, the building façade decreases energy usage by 80% related to CO₂ emissions, according to this study.
