Introduction The construction industry helps people to meet their requirements of shelter, investment, and fulfillment of some communal objective. Nonetheless, the realization of such objectives generally leads to enduring damage to the environment. Over the years, there has been a global awareness about such damage and efforts are being made to make the construction industry sustainable and accountable towards the environment. An appreciative effort was made in this field in the year 1987 when the Brundland Report was presented. Since then, there have been various developmental efforts – by way of global conferences – to increase the sustainability of buildings. The thoughts and strategies commenced by these world proceedings have provoked positive actions and many countries have put various strategies (pertaining to sustainable construction) into practice. By adopting the suggestions of sustainable construction, the building industry can contribute in an optimistic and proactive way towards safeguarding the environment. Before adopting any measures for sustainable construction, it is imperative to understand the level to which buildings have an impact on the environment. Environmental performance assessment tools offer such details so that appropriate changes can be made to the design and operation of buildings in order to make them sustainable. In this paper, global environment assessment tools such as BREEAM, LEED, Green Star, NABERS, and SBTool will be discussed. Body BREEAM The Building Research Establishment Environmental Assessment Methodology (BREEAM) is the pioneer and one of the leading environmental assessment tools in the world. It was started in 1990 in the United Kingdom by the Building Research Establishment (BRE); BRE is a charity organization. To date, more than one million buildings have been registered for certification and almost one-fourth of them have been certified. The system sets standards for best practices during the various phases of construction. The use of low-carbon products is promoted among the designers, owners, and customers. The main aim behind this is to minimize the energy demand even before it is actually put into use. So, minimizing the demand for energy comes before making and implementing plans to conserve it (BREEAM 2014). Appropriate benchmarks are set for the various phases of construction and are assessed using standard performance measures. Such standards are higher than the government guidelines. Various categories such as ecology and energy are considered while assessing the building. General aspects such as water & energy consumption, wastage, and environment are also considered for the assessment. The system is transparent and simple and has an encouraging impact on the design and other features of the construction process. The certified buildings get market recognition and the clients feel convinced that appropriate testing methods have been incorporated (BREEAM 2014). The rating benchmarks and labeling systems in BREEAM are different for different structures. An example of eco-homes is mentioned below: Total percentage available: 100% Pass: 36% to 47% Good: 58% to 69% Very good: 58% to 69% Excellent: 70% a
