The comparison study between UK daylighting simulation-Malaysia daylighting simulations due to overcast sky conditions

Due to the growing demand for building energy simulation in buildings, lot of work has been done in research since last 50 years but still a huge area needs to be covered. The current state of research, which is moving towards building energy simulation is driven by the ongoing development. The ability to analyze energy requirements accurately in new buildings at various design stages can help clients achieve optimization and meet the requirements laid down by local energy legislation. Further increase in the demand for building energy performance simulation is too completed as new policies and regulations are coming up, such as the European Union (EU) directive on building energy performance. With increasing concern in this field, architects and building designers are demanding more simulation and validation to be performed on buildings prior to construction, so as to better understand the building design and energy performance relationships. This compassion study presented the sky conditions which are varying every single second. Therefore to analyze the performance of daylighting, its effectiveness that affected into work places in two different locations in UK and Malaysia.
