Abstract
The increased awareness of energy consumption in buildings has resulted with the development of various means of predicting and rating buildings` performance. The UK developed BREEAM (Building Research Establishment - Environmental Assessment Method) and the American developed LEED (Leadership in Energy and Environmental Design) are of the most commonly used Building Performance Rating Systems worldwide. In order to predict the energy consumption in buildings and award relevant credits, BREEAM and LEED use Building Performance Simulation tools (BPS) - designated computer programs that calculate the predicted energy demand in buildings. The chance of achieving different ratings by using different standards or BPS tools raises questions concerning the ability to measure and rate 'sustainability' in a credible manner. This study performed a comparative analysis, examining variations in the results of different simulation tools (Tas, Energy Plus and IES) and their influence on the overall score of sustainable building rating systems (BREEAM and LEED) by examining a case study. Also, this study performed a detailed comparison between the assessment procedures of BREEAM and LEED. Results showed that different simulation tools resulted with different heating, cooling and total energy consumption figures. These, however, had only a minor effect on the overall BREEAM or LEED scores. Due to the differences between BREEAM and LEED assessment procedures, the case study building ended up with having different rating in each.
