Description
Summary:Building infiltration is a significant portion of the heating and cooling load of buildings and accounts for nearly 4% of the total energy use in the United States. Current measurement methods for locating and quantifying infiltration in commercial buildings to apply remediation are very limited. In this talk, the development of a new measurement system, the Acoustic Building Infiltration Measurement System (ABIMS) is presented. ABIMS uses Nearfield Acoustic Holography (NAH) to measure the sound field transmitted through a section of the building envelope. These data are used to locate and quantify the infiltration sites of a building envelope section. The basic theory of ABIMS operation and results from computer simulations are presented.
