The research surveys various rating systems for the assessment of the environmental impact of new buildings. These rating systems have been acquired by many of the developed countries nowadays, as a tool to assess and rate the environmental impact of buildings. Most of the rating systems have a similar overall structure: credits are defined for each Green Building parameter or aspect. Each credit is assigned with weight and contains a criterion for achieving this weight/point. The credits are grouped in categories per their area of reference i.e. Energy, Water, Land, etc. Applicant buildings that achieve overall points/weight which are above the threshold certification level are rated and certified per that level.
Based on the similarities and differences in weighting methods among the rating systems, the research classifies and categorizes the rating systems into three main groups:
1. Rating systems based on point allocation
2. Partial weighting method rating systems
3. Full weighting method rating systems
The comparison between the rating systems leads to conclusions regarding the structure of rating systems (i.e. rating system's categories, credits, weighting method, certification levels) and its flexibility to adjust to continuous updates and modifications. In light of the conclusions of the comparison of rating systems, the research suggests measures to improve the rating system's characteristics. A proposed rating system is developed based on the Israeli SI 5281 rating system platform. The proposed rating system is then analyzed based on various scenarios of credits selections, examining the Ramat Hanadiv Visitor Pavilion project scoring as a case study.
