Green neighbourhood: Review on the international assessment systems

Neighbourhood is widely recognised as a fundamental building block of a city, and a good starting point to create a truly sustainable community. Green neighbourhood is also broadly defined as being moderately dense, mixed-use, designed at a human scale, active and public transportation oriented and literally green. A green neighbourhood assessment system is a tool that evaluates sustainability performance of a given neighbourhood against a set of criteria. This paper evaluates 20 major international green neighbourhood assessment systems in according to their sustainability coverage and features. Sustainability aspects used in this paper include transportation, infrastructure, ecology, resources, energy, community, location, economy and building. The results of this study show that community, resources and ecology are the three major sustainability aspects that applied in 18, 17 and 16 out of 20 assessment systems respectively. However, after assessing the sustainability aspects by their weightings in the assessment systems, the differences among them are reduced and their rate of importance in all the assessment systems became closer. Ecology, energy, transportation, resources and economy receive the highest weightings after affecting by their weightings and incredibly community dropped to the very low importance of weightings. Regarding regional distribution of the systems around the world, initiative of green neighbourhood assessment system was first started in United Kingdom and European Union in 2000 and 2004 respectively and this trend reached to United States in 2005. Meanwhile, LEED (ND) with 184 certificates/projects is the main well-known systems in the world followed by Envirodevelopment in Australia and SPeAR in the United Kingdom with 100 certificates/projects each. It is also found that the highest certification fee (minimum) is LEED (ND) with US$30,000 followed by Green Star (Communities) and CASSBEE and the highest evaluation fee (maximum) goes back to DGNB followed by LEED (ND) and Green Star (Communities). Future research can be conducted on the implementation of several green neighbourhood assessment systems on actual projects and compare their capabilities in measuring the rate of greening.
