摘要：AbstractA number of Environmental Assessment Methods of Buildings (EAMB) had emerged all over the world, and a number of global variables affect the estimation of the assessment item weights in those methods. Unifying the global common variables’ effect on estimating the weights of the assessment items of all different methods among the world for different time periods helps saving the duplicated time and effort spent by experts around the world when designing new versions of the EAMBs. Therefore, it is suggested to apply an approach to determine these variables’ effect on the estimated weights of the assessment items for the different assessment methods, noting that due to the presence of other private and local variables, the final estimated weights of the items may vary from one method to another, and from one building type to another. Thus, the research aims to spot a light on the possibility and ability of unifying the importance degree and effect of the global common variables on estimating the weights of the assessment items among the EAMBs, which will not lead to unified items’ weights, but it ensures their importance degree over the world due to their worldwide concern, and reduces the duplicated effort and time waste of the experts responsible for producing the different environmental methods.
