In this study, 5 types of PVS(Passive ventilation system) units are made and expe-rimented its ventilation performance, thermal performance according to open rate and hole diameter of perforated aluminum plane. Results are as follows. 1) The ventilation performance increases approximately 5070% according by the open rate of PVS increasing. Also, the ventilation performance increases about 2%12% according by the hole diameter of PVS increasing. 2) In winter temperature/pressure condition(in20℃, out-2℃/△P0.25.0Pa) the temperature of inflow air decreases according by the open rate of PVS increasing. Heat gain performance decreases 10.1%, 25.6% when open rate increases 3) In the same condition, Heat gain performance decreases 18.3%, 18.8% according by the hole diameter of PVS increasing.Keywords:Passive ventilation( ), Building envelopes(), Breathing wall( ), Ventilation performance(), Thermal performance(), Natural ventilation () †Corresponding author Tel.: +82-51-510-2355; fax: +82-51-512-8478 E-mail address: yoon@pusan.ac.kr
