Several assessment programmes has been developed worldwide on the environmental and energy effect of buildings. The aim of this study is to identify the main and sub categories of sustainable design. The researcher has investigated and compared four global building rating systems, namely leadership in Energy and Environmental Design (LEED) in USA, Emirates Green Building Rating System (ESTIDAMA) in Abu Dhabi city, Qatar Sustainability assessment System (QSAS) in the State of Qatar and Australian green Star rating system (AGBC rating system), in Australia.

The paper outlined six main categories developed by these global rating systems being: Sustainable site, indoor environmental quality, materials, water efficiency, power supply system and innovations. Sub categories were added according to their social, cultural, economical and legislations conditions. The paper recommended adding four main categories suitable to hot and dry climate.
