Effect of Visible Light Transmittance (VLT) and ventilation modes to Vehicle Indoor Air Quality (VIAQ) / Noor Hafiz Noordin

Vehicle indoor air quality (VIAQ) has become a highly important field of research since people spend much of their time inside vehicle cabin. Volatile organic compounds (VOCs) and airborne particles are the main pollutants inside vehicle cabin. A high exposure to organic compounds and airborne parti...

This study used direct-reading instrument which are environmental monitoring instrument (EMI) and gas tracer to measure the concentration of formaldehyde and PM2.5. Meanwhile, active air sampling and analysis using gas chromatograph equipment was employed to identify the concentration of benzene, toluene, ethylbenzene and o-xylene (BTEX). It was found that high indoor temperature with heat accumulation will accelerated the melting process of interior material, where the concentrations of formaldehyde were increased up to 2 to 3 times from the initial condition during static test. Whereas, by applying window tints with 30% VLT level, the concentrations of formaldehyde and BTEX were reduced by 45%, 40%, 47%, 51% and almost 100%, respectively. However, the influence of ventilation modes to the formaldehyde, BTEX and PM2.5 concentration was more dominant compared to indoor temperature during the mobile test, in which the concentrations changed significantly under several ventilation modes. 2018 Thesis NonPeerReviewed text en http://ir.uitm.edu.my/id/eprint/26950/1/TM_NOOR%20HAFIZ%20NOORDIN%20EM%2018_5.pdf Noordin, Noor Hafiz (2018) Effect of Visible Light Transmittance (VLT) and ventilation modes to Vehicle Indoor Air Quality (VIAQ) / Noor Hafiz Noordin.
