dc.description.abstractThis study was conducted due to a concern for the indoor environment factors which affect the concentration and productivity of users in a library, where occupants spend a substantial amount of time for academic or work purposes. The place of interest in this case was the public central library area and the Headquarters office of the National Library Building, with particular reference to peak and off-peak occupancy period for the former. The IAQ audit included measurable characteristics of comfort such as operative temperature, relative humidity, air velocity and chemical pollutants such as carbon dioxide, carbon monoxide, formaldehyde, total volatile organic compounds and respirable particulate matter. When compared against the local standard SS554:2009 and international guidelines, the objective results indicated that the thermal comfort parameters were not within acceptable limits while the chemical parameters were acceptable. For the central library area, the correlation between the occupant density and contaminants concentration was demonstrated by the higher contaminants concentration during peak periods than in non-peak periods Additionally, subjective measurement is vital to assess the occupants‟ perception on parameters such as odour level which is more difficult to quantify, yet can impact the individual comfort level, concentration and productivity. NLB does a good job as 95% feel that there is no odour present. The responses in the subjective assessment reflected that overall, more than 80% of the occupants were satisfied with the level of indoor air quality in NLB. Hence, the NLB has achieved acceptable IAQ in the occupants‟ perception. The top three sick building syndromes experienced are dry eyes, dry skin and runny nose. As a result of these findings, four practical ACMV recommendations were proposed to address both objective and subjective aspects of the study. They are the re-location of carbon dioxide sensors and thermostat, overnight purging, installation of circular air diffusers and the implementation of a two stage filter design.
