Green architecture emerged as a way to address environmental problems related to buildings. Various methods have been developed to assess environmental performance, such as LEED in the United States, BREEAM in the United Kingdom, and GPRS in Egypt. The accuracy of these methods is highly important, especially considering the global trend toward requiring proof of environmental efficiency for construction permits. However, obtaining accurate results requires taking into account the variables that affect the environmental assessment. These variables include the impact of natural and human changes that occur periodically (the repetition of certain events according to day, month, and year), sequentially (changes over time), and suddenly (disasters and other unexpected events). These relationships are not addressed in current assessment methods. Since assessment has several targets, including developing a system to compare buildings according to a specific, unified scale, designers must compete to meet environmental standards based on a fair comparison; thus, the treatment of several variable effects must be obtained to reach those goals. This study, therefore, proposes an approach for considering the effects of variables when assessing item requirements. By measuring the continuity of meeting the item requirements across different time periods, this approach can achieve higher accuracy and justice in evaluation results than afforded by current methods.
