ABSTRACT

This paper reports the results of a comprehensive indoor environmental quality (IEQ) evaluation conducted in seven office buildings at an Australian university. A mix of objective and subjective assessments was carried out and a total of 519 staff participated in the survey from various non-academic departments. Three types of buildings were included in this study: ‘Heritage listed’ (c.1880–1890s), ‘Conventional’ (c.1960–1980s) and ‘Modern’ (post 2000) office buildings. Although the measured IEQ conditions were relatively good with no significant fluctuation across the selected buildings, the discrepancy between objective IEQ data and subjective occupant evaluations was noted. The Modern building type designed with fully double-glazed façades showed the highest levels of overall comfort and satisfaction and perceived productivity, whereas the Conventional building type constructed during the late 20th-century period, notable for deep floor plates, had the lowest. The heritage listed type buildings had lower window to wall ratios, yet displayed improved occupant satisfaction across all IEQ areas over the conventional type buildings. The results support that building renovation and regular maintenance can improve occupant comfort and satisfaction within offices. The findings could be useful for property managers looking for strategies to improve the performance of their building stock.

摘要

本文报告了在澳大利亚一所大学的七座办公楼中进行的综合室内环境质量 (IEQ) 评估的结果。进行了客观和主观的混合评估，共有来自各个非学术部门的 519 名员工参与了调查。本研究包括三种类型的建筑：“列入遗产名录”（约 1880-1890 年代）、“传统”（约 1960-1980 年代）和“现代”（2000 年后）办公楼。尽管所测量的 IEQ 条件相对较好，所选建筑物之间没有显着波动，但仍注意到客观 IEQ 数据与主观居住者评估之间的差异。采用全双层玻璃幕墙设计的现代建筑类型显示出最高水平的整体舒适度和满意度以及感知生产力，而在 20 世纪后期建造的传统建筑类型，以深地板而著称，最低。列入遗产名录的类型建筑的窗墙比较低，但与传统类型建筑相比，所有 IEQ 区域的居住者满意度均有所提高。结果支持建筑物翻新和定期维护可以提高办公室内的居住者舒适度和满意度。这些发现可能对寻求策略以提高其建筑存量性能的物业经理很有用。结果支持建筑物翻新和定期维护可以提高办公室内的居住者舒适度和满意度。这些发现可能对寻求策略以提高其建筑存量性能的物业经理很有用。结果支持建筑物翻新和定期维护可以提高办公室内的居住者舒适度和满意度。这些发现可能对寻求策略以提高其建筑存量性能的物业经理很有用。
