ABSTRACT

Indoor environmental quality (IEQ) of buildings plays an important role in affecting building occupants’ comfort, health and well-being. However, there is limited understanding of the critical IEQ factors that affect occupants’ work productivity in university office buildings. By surveying 204 people (72 university staff members and 132 postgraduate students) in a tertiary education institution in New Zealand, this research aimed to identify and rank the critical IEQ factors concerning their perceived productivity and how the perceived importance of these factors differed between staff and student cohorts. Statistical analysis identified a total of 16 IEQ factors as important in affecting work productivity, and 15 of them, except cleanliness of the office, could be grouped into four categories: (1) thermal comfort and lighting; (2) acoustics and privacy comfort; (3) spatial comfort and (4) aesthetics and views. Based on the identified critical IEQ factors, a framework was developed and can be used by building facility managers and designers in the tertiary education sector to optimize design solutions to improve building performance that is more conducive to their occupants. The findings from this research can inform the inclusion of design features that will enable staff and students using these buildings to achieve better productivity.

摘要

建筑物的室内环境质量（IEQ）对影响建筑物居住者的舒适度、健康和福祉起着重要作用。然而，人们对影响大学办公楼居住者工作效率的关键 IEQ 因素了解有限。通过对新西兰一所高等教育机构的 204 人（72 名大学教职人员和 132 名研究生）进行调查，本研究旨在确定与他们感知生产力相关的关键 IEQ 因素并进行排名，以及教职员工和学生之间对这些因素的感知重要性有何不同。学生群体。统计分析发现，影响工作效率的IEQ因素共有16个，其中除办公室清洁度外，其中15个因素可分为四类：(1)热舒适度和采光；(2)声学和隐私舒适度；（3）空间舒适度和（4）美观和景观。根据已确定的关键 IEQ 因素，开发了一个框架，高等教育部门的建筑设施经理和设计师可以使用该框架来优化设计解决方案，以提高建筑性能，更有利于居住者。这项研究的结果可以告知纳入设计功能，使工作人员和学生使用这些建筑能够实现更好的生产力。开发了一个框架，可供高等教育部门的建筑设施管理者和设计师使用，以优化设计解决方案，从而提高建筑性能，使其更有利于居住者。这项研究的结果可以告知纳入设计功能，使工作人员和学生使用这些建筑能够实现更好的生产力。开发了一个框架，可供高等教育部门的建筑设施管理者和设计师使用，以优化设计解决方案，从而提高建筑性能，使其更有利于居住者。这项研究的结果可以告知纳入设计功能，使工作人员和学生使用这些建筑能够实现更好的生产力。
