Effect of Façade Type on the Cooling Load of a Multi-Storey Building

Abstract

The thermal and energy implications of a number of facade configurations on the lowest potential energy consumption for a multi-storey building have been investigated using the IES Virtual Environment software package. A preliminary 3-Dimensional computer model of the building was created and a number of different analyses were undertaken to ascertain the optimum facade configuration from an occupant comfort and thermal energy consumption perspective. Results have demonstrated that any one facade or glazing type will not provide the best solution in terms of peak loads, overall energy consumption, occupant comfort and cost. Any solution must therefore be a compromise between these competing factors. On the basis of these results, it has been found that a higher performance glazing results in the lowest peak cooling load, however, a more moderate performance glazing results in the best overall energy consumption.
