چکیده انگلیسی
Literature suggests there are many challenges related to the thermal modeling of building walls, including proper representation of frame cavity and boundary condition. Although simple 2D finite element (FE) tool (THERM5.0) has been certified by NFRC, its limitations have not been well understood. In order to address industry challenges and to develop a better understanding of the limitations of 2D analysis, a 3D finite element analysis thermal modeling approach has been developed. This paper outlines findings from guarded hot box tests of three walls: a conventional wall, two continuous insulation walls one with spray polyurethane foam (SPF) and one without SPF; and compares the results of the testing with FEA modeling for the same three walls. The results show significantly increased performance of continuous insulation with SPF filled cavity vs. typical gypsum wall with fiberglass insulation.
