New findings on measurements of very airtight buildings and apartments

The trend in European countries, such as Belgium, France and Germany is that the quality of the airtightness of the building envelope is getting better and better. This is true for small, airtight apartments, Passive houses and some large buildings with an excellent airtightness due to special requirements, e.g. oxygen reduction or fire protection.

Modelling thermal comfort and energy consumption of a typical mixed-cooling apartment in Guilin, China

Many studies have shown that the use of mixed-mode cooling can bring down the cooling load significantly while maintaining satisfactory in door air quality and thermal comfort. But there is little information available concerning mixed-mode cooling in China. Thus, basing on design parameters of design standard, A series of computer simulation of a typical mixed-cooling apartment in Guilin, lies south-west of China, was conducted by Eneryplus and Climate Consultant software.

Effect of measurement location of air air-tightness performance on apartment units in Korea

The purpose of this study is to evaluate the effects of measuring position of air-tightness performance in Flat-type and Tower-type apartments. Air-tightness performance was measured on entrance doors using the Blower Door System in accordance with CAN/CGSB 149 and on the windows using air-tightness Measuring (KNS-serise) in accordance with JIS A 2201. The air-tightness test was performed with newly builted apartments in 2011. The air-tightness test results on location were converted into ACH50 for comparison.
