Abstract
This image is used in a system that can automatically calculate and refer to the performance values of the thermal transmission coefficient and solar heat gain coefficient of building openings, and shows the conformance of sashes and doors to a standard insulation grade. Specifically, for multiple sashes and doors, the worst performance value for the selected product, type, and glass specification is displayed, and as shown in the "Reference diagram showing the usage status," conformance or non-conformance with each standard is displayed as an overall judgment using color and text.
