The effectiveness of the indoor air quality improvement project in an office building - a case study

摘要

Indoor Air Quality Act was enacted by Taiwan EPA in 2011. It was common of poor indoor air quality in office spaces before 2011. The purpose of this study is to assess the effectiveness of the IAQ improvement project in a bank, Taipei, Taiwan. Indoor levels of carbon monoxide, carbon dioxide, total VOCs, formaldehyde, ozone, particulates (PM_(10) and PM_(2.5)), temperature, and humidity were monitored in seven departments. The strategies of improvement included ventilation enhancement, copy machines isolation and office space rearrangement. The concentrations of carbon dioxide (% over 1000ppm) measured in 2011, 2012 and 2014 were averaged with 1767ppm (100%), 768ppm (6%) and 596ppm (0%), respectively. All of the concentrations of other parameters measured in 2014 were lower than national standards. We are sure of making certain changes such as ventilation improvement, pollutants isolation and IAQ Act implement can go a long way in improving IAQ.
