Measured and perceived indoor air quality in three low-energy wooden test buildings

Stricter energy efficiency requirements of buildings have raised concerns about their effects on indoor air quality (IAQ). We studied measured and perceived IAQ in three low-energy wooden test using ventilation levels (0.5, 1.0, 2.0 (dm3/s)/m2). measurements included VOC (volatile organic compounds) sampling continuous several indicators. Perceived (PAQ) was investigated with a sensory panel untrained volunteers. The results show that the TVOC (Total VOC) concentrations were relatively low two already at beginning study (100–141 µg/m3), decreased all when increased from lowest level. third building made pinewood timber showed higher (340–857 especially for terpene compounds are generally present emissions. In PAQ assessment, percentage people dissatisfied (PD) buildings. However, highest ventilation, had second-lowest PD despite levels. findings this can be utilized interpreting design material selection
