Abstract

The problem of fugitive pollutants arising from the extensive use of indoor building materials in air-conditioned buildings in Taiwan directly affects the indoor air quality and indirectly affects the control of indoor ventilation rate. Thus, how to balance the building indoor "healthy air quality" and "energy-saving ventilation" has become an important issue. This 3-year research project discusses the impact of "different ventilation rates" (0.25-2.0 ACH) on the calculation of the fugitive pollutants of "H-EBMs" and "L-EBMs", and calculate the "ventilation removal efficiency". It also probes into the application of different "SBMs" in indoor space to adsorb the pollutants in the air (formaldehyde) by calculating "sorption flux per time per area", "sorption efficiency" and "sorption equivalent ventilation rate per area". According to the standard method of ISO 16000, this study conducted the building material fugitive and absorption experiments by testing with two building materials (55m3, 0.099m3) environmental chamber (25°C, 50% RH, Loading Factor 0.4 m2/m3). The research results showed that increased ventilation rate can effectively lower H-EBMs pollutant concentration. The sorption equivalent ventilation rate per area of SBMs is also the most effective. If used, it can reduce ventilation and maintain indoor air quality.
