Impact of building geometry factors on thermal comfort and energy performances of glass façade high-rise office buildings in hot and humid climate Malaysia
Limited land in cities have caused an increase of high-rise buildings and caused changes in the morphology and microclimate. Besides, the application of full glass façade on high-rise buildings has become a trend and could influence the building energy and thermal comfort in hot and humid climate. T...

Limited land in cities have caused an increase of high-rise buildings and caused changes in the morphology and microclimate.

A base case model of 20-storey high-rise building with a full glass façade was simulated using the EnergyPlus and RStudio programmes.
