Abstract: Recently, research on energy saving in buildings attracts more and more attention. In present work, the effect of phase change material wall (PCW) and night ventilation (NV) on energy saving of a typical office building in five key cities (Lhasa, Xi’an, Kunming, Chengdu and Urumchi) in Western China, is investigated using EnergyPlus 8.6. The influences of different climate conditions, phase change temperature, NV rates on mean indoor temperature are carefully studied. Suitability and energy saving potential of PCW integrated with NV are also analysed. The results contribute towards a more comprehensive evaluation and understanding of interaction effects between PCW and NV.
