Evaluation of the Effect of the Different Distances between Two Facades Natural Ventilation on Atrium Buildings with DSF and PMV-PPD Comfort

The energy efficiency and thermal performance of double facade glazed buildings are often questioned. However, nowadays especially glazed double skin facades buildings are increasingly being built around the world; the building facade plays an important role in achieving thermal comfort and energy conservation. Due to technological advances, transparency and the use of glass has become an attractive envelope option in architectural design. Building glass facades can provide outdoor views and an excellent level of natural light as well as the potential for natural ventilation. However, with the use of glass, heat loss during the winter and solar gain during the summer will increase energy loads. This study of aim is to determine the effect of thermal comfort in building and performance of surfaces, to determine if a DSF configuration will provide a better thermal comfort through mechanically assisted natural ventilation. By using the CFD program, this study were analysed the thermal comfort statuses of different atrium buildings volumes with double skin facades. (C) 2015 The Authors. Published by Elsevier Ltd.
