Abstract Understanding occupants’ satisfaction with their environment is an important step to improve indoor environmental quality (IEQ). These satisfaction data are limited to Singaporean commercial buildings. We surveyed (N = 666) occupant satisfaction with 18 IEQ parameters in seven Green Mark certified air-conditioned commercial buildings in Singapore. About 78% of the participants expressed satisfaction with their overall workspace environment. Occupants were most satisfied with flexibility of dress code (86% satisfaction), electrical lighting (84%) and cleanliness (82%), and most dissatisfied with sound privacy (42% dissatisfaction), personal control (32%) and temperature (30%). We found that satisfaction with cleanliness has the highest impact to overall workspace environment satisfaction. Our results suggest achieving high occupant satisfaction for some IEQ factors is harder than others, which suggests the premise of singular satisfaction rating (e.g., 80%) that applies to all IEQ parameters may not be reliable and representative. We determined that the major contributors to thermal dissatisfaction were insufficient air movement and overcooled workspaces. Occupants in open plan office were unhappy with the noise produced by their nearby colleagues. We also found that several IEQ variables (odors, air movement, available space, overall privacy, sound privacy and temperature) which are not statistically significant to the overall workspace satisfaction on their own, but their impacts becomes substantial when these IEQ variables are merged into larger environmental factors (i.e., Perceived Air Quality, Acoustics, Layout and Thermal). These results can support the development of an IEQ benchmarks for commercial buildings in Singapore.

新加坡七座商业建筑的室内环境满意度

摘要 了解居住者对环境的满意度是改善室内环境质量（IEQ）的重要步骤。这些满意度数据仅限于新加坡的商业建筑。我们对新加坡七座获得绿色标志认证的空调商业建筑的 18 个 IEQ 参数进行了调查（N = 666）。大约 78% 的参与者对他们的整体工作空间环境表示满意。居住者对着装要求的灵活性（86% 满意）、电气照明（84%）和清洁度（82%）最满意，对声音隐私（42% 不满意）、个人控制（32%）和温度（30%）最不满意%）。我们发现对清洁度的满意度对整体工作空间环境满意度的影响最大。我们的结果表明，为某些 IEQ 因素实现高居住者满意度比其他因素更难，这表明适用于所有 IEQ 参数的单一满意度评级（例如，80%）的前提可能并不可靠和具有代表性。我们确定导致热不满意的主要原因是空气流动不足和工作空间过冷。开放式办公室的住户对附近同事产生的噪音感到不满。我们还发现几个 IEQ 变量（气味、空气流动、可用空间、整体隐私、声音隐私和温度）本身对整体工作空间满意度没有统计意义，但是当这些 IEQ 变量合并到更大的环境因素（即感知空气质量、声学、布局和热量）。
