Abstract: Iran’s energy intensity in 2013 was four times the global average. The construction sector is responsible for about 40% of this consumption and the average energy consumption per square meter of the building isn’t good compared to other countries. Today, the green building rating systems, as a method of environmental assessment of buildings has developed significantly. In line with promoting green building standards, these systems are of significant help for designers and builders and therefore, their usage has been increased day by day. However, selection of suitable criteria and weighting them is one of the challenges for developing and using these systems. This choice without considering the climatic conditions, the geographic location and the environmental priorities isn’t possible. Hence, the development of regional ranking systems, comparing to international systems is of great importance. In this study with the aim of achieving a rating system in accordance with climatic conditions and environmental restrictions of our country, at first a comprehensive study on the available ranking systems have been done. Then among existing system, 6 of them including LEED, BREEAM, Pearl, GPRS, QSAS and SEAM have been selected and their criteria were categorized. Then by removing the similar criteria, a basket of 133 criteria is derived which is then divided into 11 groups. Afterwards, by forming a team of experts and performing a deep interview, a basket of 68 modified indexes in 8 areas was obtained. Then, by using the AHP technique and Expert-Choice Software, categories were compared and weighted. By calculating the coefficient of incompatibility, the comparison results are verified. We compared the proposed rating model, called Iran sustainable building rating system with the six other ranking systems and the obtained results are analyzed and the benefits of the system are discussed. At the end, we discuss our suggestions for the promotion and future development of the system.
