中国是世界上最大的能源消费体系，在实现政府承诺的碳达峰、碳中和目标方面面临诸多挑战。办公建筑作为建筑面积最大的公共建筑类型，节能减排潜力巨大。为了实现这一目标，建筑设计师的目标是被动解决方案，可以满足居住者的热舒适需求，同时降低能耗。本研究旨在开发一种决策方法，从成千上万的设计方案中选择最佳的解决方案，考虑能源消耗，舒适度和成本的因素。我们开发了一种新的优化决策方法与上述三个目标。该模型包括三个阶段：1）参考建筑模型的建立; 2）敏感性分析，识别主要影响变量; 3）应用NSGA-II和TOPSIS方法建立优化决策模型。通过应用这三个阶段的决策模型，本文首先提出了具有成本效益的被动式设计解决方案，在整个夏热冬冷气候区的办公建筑。最后，以上海市某办公楼为例，通过对该办公楼进行为期两年的能耗审计和热舒适度调查，验证了该方案的实际应用效果。很明显，所提出的解决方案为新的办公建筑低能耗建筑设计指南提供了支持沿着对中国夏热冬冷气候区的现有标准进行了必要的修订。(c)2022爱思唯尔有限公司版权所有。
China, with the largest energy consumption system in the world, faces numerous challenges in achieving the government's commitment to reach a carbon-peak and carbon-neutral target. As the most common public building type in terms of floor area, office buildings have great potential for energy saving and emissions reduction. To meet this target, building designers target passive solutions that can meet the thermal comfort needs of occupants and also reduce energy consumption. This study aims to develop a decision-making method to select optimal solutions from among tens of thousands of design options considering the factors of energy consumption, comfort, and cost. We developed a novel optimization decision approach with the above-mentioned three objectives. The model consists of three stages: 1) the establishment of the reference building model, 2) sensitivity analysis to identify the main influencing variables and 3) the establishment of the optimization and decision-making model by applying NSGA-II and TOPSIS methods. By applying this three-stage decision-making model, this paper first proposes costeffective passive design solutions for office buildings throughout the Hot Summer and Cold Winter climate zone. Finally, an office building in Shanghai was chosen as a case study to demonstrate the practical implementation of the proposed solutions through a post-occupancy evaluation with a two-year energy auditing and thermal comfort survey. It is evident that the proposed solutions provide support for the new low energy building design guide for office buildings along with necessary revisions to the existing standards for the Hot Summer and Cold Winter climate zone in China.
