感知空气质量，病态建筑综合征（SBS）的症状和生产力进行了研究，在现有的办公室，空气污染水平可以通过引入或删除污染源进行修改。这种可逆的干预措施使空间能够按照新的欧洲室内环境设计标准CEN CR 1752（1998）的规定，被分类为非低污染或低污染。污染源是一条用了20年的旧地毯，它被放在屏风后面的架子上，这样住户就看不见了。5组6名女性受试者暴露于办公室的条件下两次，一次有污染源，一次无污染源，每次暴露在下午265分钟，一次一组。他们在进行模拟办公室工作时评估了感知的空气质量和SBS症状。当污染源存在时，受试者对办公室空气质量的可接受程度为22%，而当污染源不存在时，则为15%。在前一种情况下，在文本打字和计算任务中，头痛的患病率显着增加（P = 0.04），报告的努力水平显着降低（P = 0.02），这两者都需要持续的集中水平。在文本打字任务中，受试者的工作速度显着更慢时，污染源存在于办公室（P = 0.003），打字6.5%的文本比当污染源不存在于办公室减少室内空气污染负荷被证明是一种有效的手段，提高舒适度，健康和生产力的建筑物居住者。
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.
