Abstract: Building energy simulation is commonly used to quantify the savings and/or penalties of a variety of energy efficiency techniques and to estimate monthly and annual energy consumption of the buildings. This quantification however, might not be reliable as a result of a deterministic approach in simulation. Estimated energy performance based on typical meteorological year such as TMY and weather year for energy calculation (WYEC) may not reflect the actual energy performance. In addition, TMY does not capture the extreme weather condition. This paper investigates the long-term performance of roof designs based on a variety of different combinations of roof solar reflectance and thermal insulation. The focus is studying the potential deviation of energy performance of different roof designs based on CWEC weather data and that under long-term actual weather scenario.
