Impact of curtain wall configurations on building energy performance in the perimeter zone for a cold climate

The Analysis of Variances (ANOVA) approach is used to quantify the impact of nine curtain wall design parameters on the energy consumption of an office space in the perimeter zone of a typical office building in Montreal. The uncertainty analysis shows that the variation in curtain wall configurations has generally a greater impact on the cooling followed by heating, lighting and total energy consumption. The global sensitivity analysis shows that the window wall ratio is the most significant design parameter influencing the end-use energy consumption. (C) 2015 The Authors. Published by Elsevier Ltd.
