On trends of 'well-being', heat recovery ventilators(HRV) are recently installed in high rise buildings. HRV is not energy saving instrument but ventilating one. But many people have not been aware of the accurate fact. In this study, performances of HRV are tested under foreign and domestic standards. Especially air-tightness is measured three times by using gas concentration method and pressing equipment. Net effective ventilating air volume is acquired by solving gas concentration equations. After research air-tightness and effective ventilating air volume must be more focused on than heat transfer efficiency to select the optimal HRV. Heat transfer efficiency must be adjusted by air-tightness results.

On trend of ‘wellbeing’, installation of large gas range hood has taken place in recent times in the domestic super high-rise & high-quality apartments to improve the life quality in Korea. Due to the lack of sufficient information on the performance level of these hoods, however, the construction industry is forced to rely on each supplier’s simple catalogue. But most of these suppliers can not afford any independent performance testing of their own products, resulting a credibility problem. At the same time, due to the height and pressure difference between the upper-level floor and the ground level, occurrences of significant foul ordure have been reported because of the back flow of its ventilation circulation from vertical duct, resulting a lower quality of life of the tenants. So residents claim for the bad indoor quality, asserting all responsibility are belong to construction company. To solve this situation, first of all, to know and test the hoods sold in market thoroughly, especially performance, may be the first step and critical. Purpose of this research is to acquire the method to select the optimal gas range hood through the performance test under KS or prEN codes, such as performance curve, noise level, capture efficiency and power consumption and the reasonable grounds to adapt the optimal one to our construction fields. After research, to bestow weigh function on noise level is considered more important item than any others. Additionally, the comparison general hoods and functional hoods was accomplished under economical efficiency.

An infiltration was realized as an important part of ventilation to change fresh air with contaminated air in a house. In this study, it was measured the infiltration in new apartment buildings according to Seasons, height etc. We measured the infiltration by using tracer gas method and did for 24hours. To quantify the infiltration, Sulfur Hexafluoride(SF?) gas was used. The Constant Concentration was conducted during experimental process and the concentration of the gas was measured with a gas monitor. In the results of the measurement, the infiltration were appeared over 0.6 ACH in winter and about 0.2 ACH in summer and autumn. Also the infiltration were measured more highly at high and low stories than middle stories in winter.
