Evaluation of the Green Pyramid Rating System in Office Buildings in Egypt

This study aims to investigate and assess the credits of GBRSs to achieve sustainability and find the most practical and applicable method in Egypt. The study consisted primarily of three stages: a theoretical approach, a comparative analysis, and case studies. To determine their possible certification level, the Egyptian GPRS was used to analyze and reevaluate four Egyptian LEED-certified projects, all of which were LEED BD + C: NC-certified and classified as office buildings. Regarding the certification levels granted, the study found that the LEED rating system had a more realistic portrayal of sustainability than the GPRS. As a result, it was determined that LEED is a better choice for Egyptian office buildings. However, GPRS awards more points for water efficiency, which is significant because Egypt has concerns with both availability and demand for water. Thus, GPRS can be suitable for Egyptian projects, but not office buildings specifically, with a few adjustments applied to it. This study is significant due to the lack of studies evaluating the sustainability pillars that GPRS and LEED address.
