Improving for indoor air quality selective, simple and quick assessment: case study

Research output: Contribution to conferencePaperpeer-review

Abstract

Case study results show that even if carbon dioxide (CO2) level in all premises was below recommended level, the particulate matter (PM) number concentration was up to background level in old-historical building because of poorly adapted ventilation for office purposes. In additional, objective improvement of ventilation systems in industrial premises shows excellent results (close to clean room level) despite to occupational PM emission. Furthermore, office premises' results show higher levels of PM even CO2 level was below recommended values - 1000 ppm. In general, this is a remarkable example that a complex approach is necessary for better indoor air quality assessment, e.g., additional parameters which could also describe purposive ventilation installation and efficiency rate in building and premises. And buildings with historical - architectural value could be poorly suitable to achieve exceptional occupational indoor air quality.
