Abstract
Airtightness standards using fan pressurization method are normally used for measuring small buildings, detached houses, and apartment units. And, it is easy to conduct airtightness measurement through this fan pressurization method. However, it can be difficult to achieve accurate measurement results for the large buildings as the height and volume of the buildings have been increased. In this paper, we studied the principle of airtightness method by fan pressurization. And, we reviewed the measurement process described in ISO 9972, EN 13829, ASTM E779, ATTMA TS 1, CAN/CGSB 149.15, and JIS A 2201. Then, we categorized the methods` items according by air flow rate (Q) and pressure difference($\small{{\Delta}P}$). As a result, we made a comparison analysis on the measurement methods appeared in each standards. And, we achieved 5 test conditions about air flow rate and pressure difference to state requirements for large buildings airtightness measurement.
