7. METHODOLOGY OF STUDY
All of the building rating system organizations has
published their standards in which they have
mentioned the method of calculation of weightages
and rating criteria. Due to the regional variation the
weightages and even the assessment tools differ from
each other. So it is not possible to look into the details
of assessment tools of all the rating systems. Here in
this paper only the five common assessment tools
have been taken for comparisons which are the
important part of each of the rating system. Similarly
each rating system provides different weightage s to
the assessment tools and the sum of all the weightages
is also differs from each other. Hence in this paper the
percentage of each assessment tool for all of the
rating systems have been calculated and compared.
Figure 1 shows the comparison of weighted
percentages for some rating systems.
