Abstract: The proposed work to be carried out by an undergraduate student supported by the 2017 RRF Undergraduate Assistantship will expand ongoing computational activities with a proof of concept demonstrator for novel building infiltration-assessment technology. Current technology to assess infiltration almost exclusively relies on a Blower Door Test (BDT), and is limited to one time measurement upon building commissioning. The work proposed work will generate the proof of concept of a distributed differential-pressure recovery time system that remains installed in the building and that is capable of continuously measuring infiltration and building envelope health. This work can contribute to reducing the 34% of energy losses in residential buildings attributable to infiltration in Maine, having an economic impact of over $500 million. The undergraduate research assistant will gain unique research experience in this novel technology and will be uniquely positioned to engage in the industrial sectors of energy efficiency and home automation (annual growth rate of 17%), both important growth areas at the regional and national level.
