The attainment of framework of sustainable construction principles is implemented through legislation, policies and strategies (i.e. methods, building tools and construction practices). Legislation and policy were introduced by construction organisation, and the governments worldwide to control the impact of construction activities on society and the environment. It is a minimum requirement and compliance of construction firms to follow professional and industry codes of practice and guidelines when implementing sustainable construction practices. The imposing of legislations and policies has driven construction firms to strategic plan their construction activities (Tan, Shen & Yao 2010).Australia 6 star energy rating Environmental management

Building assessment tools measures a building’s environmental performances over its life cycle by developing a criteria benchmark. The criteria consist of areas from environment, economic and social. It is divided into two categories from assessment and rating tools. The differences between the two is with assessment tools it provides quantitative performance indicators for design alternatives whereas rating tools determine the building performance levels in stars. The first environmental building assessment tools to be used was called BREEAM that was developed by The Building Research Establishment in 1990. Since then, many new assessment methods have been developed throughout the world. In Australia, the first comprehensive method for evaluating environmental building performance called Green Star developed by the Green Building Council of Australia (GBCA) in 2003. The Green Star rating tool addresses the sustainability aspects of the project during the design and construction stage into nine categories from Management, Indoor Environment Quality, Energy, Transport, Water, Emissions, Materials, Land use, & Ecology, Innovation. These categories are distributed into credits (indicators) which addresses each of the specific sustainable performance. Once the credits are distributed into categories, environmental weightings is applied. The level of
