International green building systems and Egyptian green pyramid system: A comparative study

The construction sector causes bad environmental effects. Consequently, several worldwide Green Building Rating Systems (GBRSs) have been created delivering a standard Credit Criteria (CC) for evaluating Green Building functioning. On the other hand, there is an obvious absence of study on determining a baseline to build novel Green Building Rating System and to assess the current Systems. Therefore, this study determines main Credit Criteria using a general literature review, and aims to assess these Criteria based on International Green Building Systems and Egyptian Green Pyramid System. The analysis is built on a numerical quantity which is acquired throughout giving credit values of chosen systems to the recognized main Credit Criteria. The assessment of these Credit Criteria can be assumed as a reference to create novel Green Building Rating System and it supplies effective outcomes to improve the current system further. It is discovered that 'Energy' yardstick is the greatest commonly believed main criteria and then followed by 'Water' criteria. On the other hand, Credit Criteria such as 'Financial aspects', 'Sustainable designing', 'Stakeholder relationships' and 'waste reduction' are recognized as potential Credit Criteria which can be involved in upgrading the assessment system in the future.
