Perceived air quality, Sick Building Syndrome (SBS) symptoms and productivity were studied in an existing office in which the air pollution level could be modified by introducing or removing a pollution source. This reversible intervention allowed the space to be classified as either non-low-polluting or low-polluting, as specified in the new European design criteria for the indoor environment CEN CR 1752 (1998). The pollution source was a 20-year-old used carpet which was introduced on a rack behind a screen so that it was invisible to the occupants. Five groups of six female subjects each were exposed to the conditions in the office twice, once with the pollution source present and once with the pollution source absent, each exposure being 265 min in the afternoon, one group at a time. They assessed the perceived air quality and SBS symptoms while performing simulated office work. The subject-rated acceptability of the perceived air quality in the office corresponded to 22% dissatisfied when the pollution source was present, and to 15% dissatisfied when the pollution source was absent. In the former condition there was a significantly increased prevalence of headaches (P = 0.04) and significantly lower levels of reported effort (p = 0.02) during the text typing and calculation tasks, both of which required a sustained level of concentration. In the text typing task, subjects worked significantly more slowly when the pollution source was present in the office (P = 0.003), typing 6.5% less text than when the pollution source was absent from the office Reducing the pollution load on indoor air proved to be an effective means of improving the comfort, health and productivity of building occupants.
在一间现有办公室中，对可感知空气质量、病态建筑综合征（SBS）症状及工作效率进行了研究。在该办公室中，可通过引入或移除污染源来改变空气污染水平。这种可逆干预使得该空间可根据新的欧洲室内环境设计标准CEN CR 1752（1998）被分类为非低污染或低污染。污染源是一块使用了20年的旧地毯，将其放置在屏风后的架子上，这样办公人员就看不见它。五组受试者，每组六名女性，在办公室的环境中接受了两次测试，一次是存在污染源的情况，一次是没有污染源的情况，每次测试在下午进行，时长为265分钟，每次一组。她们在进行模拟办公工作时评估了可感知空气质量和SBS症状。办公人员对可感知空气质量的主观评价显示，存在污染源时，有22%的人不满意；不存在污染源时，有15%的人不满意。在前一种情况下，头痛的发生率显著增加（P = 0.04），并且在文本录入和计算任务中（这两项任务都需要持续的注意力），报告的努力程度显著降低（p = 0.02）。在文本录入任务中，办公室存在污染源时，受试者的工作速度明显更慢（P = 0.003），录入的文本比办公室没有污染源时少6.5%。事实证明，降低室内空气的污染负荷是提高建筑 occupants 的舒适度、健康水平和工作效率的有效手段。 （注：这里原文“occupants”直译为“居住者”，结合前文推测这里实际指办公人员，译文已修正）
