Building Airtightness Modifier

This paper aims to present the elaboration of a device able to modify the airtightness of a test House. This project has been conducted with three Master student groups in the framework of their research projects from 2015 to 2017. The TIPEE IEQ test House, comprising of two floors and eight rooms, is dedicated to the study of Indoor Air Quality (IAQ), thermal comfort and energy consumption. Its envelope has been designed to reach an airtightness target slightly lower than the French Energy Efficiency Standard RT2012 requirement for dwellings i.e.
