these results highlight the risks associated with the use of high-level benchmark.
even though the wider range of energy consumption benchmark encompasses the predicted and measured consumption in both offices, the use of such an extensive range would present a large uncertainty.
there is clearly a variation in energy consumption and power demand among building that would fall under the same benchmark category, suggesting a need for more appropriate, small power specific benchmark categories or the use of a model such as proposed here.
the use benchmark for peak demand would have significant implications on the systems design, potentially resulting in oversized cooling systems.
