AN EVALUATIVE METHOD FOR HIGH-PERFORMANCE WINDOW SYSTEMAND WINDOW SIDE RADIATION ENVIRONMENT

摘要

A study was performed on a method to evaluaternperformance of window system necessary to satisfactorilyrnmaintain the window side radiation environmentrnin a glass building. On general type windowrnusing high-performance glass, air flow window andrnpush-pull window, U-factors and SCs in variousrnspecifications were obtained from numerical calculation.rnAlso, a simulation model for indoor radiationrnenvironment is proposed using the newly definedrnwindow thermal property values. As an evaluationrnindex of radiation environment,"OT increase onrnwindow side" is proposed, and a window system isrnindicated, which is recommendable from the viewpointrnof numerical analysis performed on officernbuildings.
