Construction industry became the most significant. Therefore, great efforts have been carried out in the field of sustainable development. In addition, new researches and codes of design and construction have been conducted. This paper presents a green rating model to assess the sustainability of administration buildings in Egypt. Twenty-four factors have been gathered from literature. The factors are divided into five groups: The project aspects group, the site aspects group, Material aspects group, resources aspects group, and Management and innovation aspects group. The project aspects group includes: Controlling emission from building materials, protecting water sources from pollution, Acoustic comfort, Project waste management plan, Minimizing pollution during construction. The site aspects group includes: Site selection, Development density and community connectivity, Public transportation access, Low emitting and fuel efficient vehicles, and Maximize open space. Materials aspect group includes: Regionally procured materials, Materials fabricated on site, Use of renewable materials, Use of recycled materials, and Life cycle cost analysis of materials in the project. Resources aspects group includes: Use of higher durability materials, efficient water use during construction, Energy efficiency improvement, and Renewable energy sources. Management and innovation aspects group includes: Providing building user guide, providing a periodic maintenance schedule, Respect for sites of historic or cultural interest, Cultural heritage, and innovation and flexibility in design. Sustainable rating model has been proposed to assess the sustainability of administration buildings in Egypt. The proposed rating model can be used in case of residential buildings.
