Evaluation of energy performance of LEED building (Friedman) at UBC : technical report Logawa, Banda; Kourkoulis, Ioannis


Recent studies conducted by New Buildings Institute have shown that there were gaps between modeled and actual performance of numerous LEED Buildings. This study was conducted to investigate this phenomenon in one of LEED Buildings in University of British Columbia, try to identify possible sources of discrepancies, and establish guidelines to repeat similar investigations on other buildings. Based on the recommendations of the project client, Friedman Building was chosen in the study. To achieve the project objectives, several efforts were made such as analyzing annual and monthly energy consumption data, comparing LEED drawings and as-built drawings, comparing the occupancy pattern in the building, and conducting interviews with the program administrators. There were several sources of discrepancies identified in the study: changes in energy demand throughout the year, changes in design before and after submission of LEED Application, inaccurate plug load assumptions, and building envelope degradation.
