Recalculating the sustainability criteria within the LEED system according to the Syrian construction conditions using the FAHP method
Background: With the global trend to develop the construction industry and achieve the sustainability of resources, a set of systems have emerged to assess sustainable buildings, the most important of which are the Environmental Efficiency Rating System (BREEAM) in the United Kingdom, the LEED method for evaluating sustainable buildings in the United States, the Green Globes Rating System in Canada, and the ESTIDAMA Pearl Rating method. In the UAE, the Green Pyramid Rating System in the Arab Republic of Egypt and many others.
Methods: This study determined the main standards and their relative weights included in the American LEED system and then re-weighted according to the Syrian construction conditions using a (fuzzy analytic hierarchy process) (FAHP).
Results and Conclusion: The study showed that it is impossible to find a stable and effective evaluation system at every time and place due to the different construction conditions, economic situation, and priorities between one country and another, as well as the difference in climatic conditions between one region and another. Although the researchers used the same main criteria adopted in America, the results in Syria differed. This reflects the local situation in the study area (Syria).
