PT Journal AU Patko, C Patko, I Pasztory, Z TI The Presence of Volatile Organic Compounds (VOCs) Indoors During the Heating Season: in situ Emission Study of a Frame-house SO Acta Mechanica Slovaca PY 2013 BP 70 EP 78 VL 17 IS 3 DI 10.21496/ams.2013.035 DE Volatile organic compounds; indoor air quality; lightweight construction wooden house; low-energy buildings; emission of building materials AB Due to the more stringent energy regulations the air-tightness and insulation of buildings is much higher than in old buildings. As a result of synthetic building materials and reduced air exchange rates indoor air quality is deteriorating significantly. In this study we examined the indoor air quality of a newly built, frame-house during the heating season. Formaldehyde (11-130 μg/m3), 3-carene (133-300 μg/m3) and alpha-pinene (130-300 μg/m3) values varied over a wide range depending on the indoor activities. We determined that further measurements are required on the subject during the summer period as well. ER
