In a 2004 controlled lab experiment in National research council Canada in Canada, Bradley,J.S & Gover, identify the percentage increase in perceived productivity (reported as reduced noise interference with performance). The report represents a 18% improvement in performance on editing test and a 16% improvement in performance on math test by decreasing level of SII (from 0.55 to 0.20). In a 2008 case study, by displacing 60” high partition and 3/4” acoustic ceiling, the level of SII was attenuated at 0.20."
In a 2011 intervention Study in India, Alok and Schweta identiﬁed 31% improvement in computer typing task by changing work environment; computer workstation furniture and equipment (desk, keyboard, footrest), color, light, and the positioning of switches and accessories (clock). The related productivity is the input data which is 4% of total ofﬁce productivity, thus 1.2% of total improvement on ofﬁce work can be estimated. "
Temperature and Illumination
In a 2012 controlled lab experiment in India, Komalanathan and Thangavelu identiﬁed 11% improvement in performance on cognition test. The optimum level of indoor temperature at 21°C and illumination at 1000lux has improved the work performance and health of ofﬁce workers. The related performance of the test is letter search, memory span, reasoning, numerical addition, and comprehensive reading."
