Article #1413 - AEDG Implementation Recommendations: Doors

The Advanced Energy Design Guide (AEDG) seeks to achieve 30 percent savings over Standard 90.1-1999. This guide focuses on improvements to small office buildings, less than 20,000 square feet. The recommendations below are adapted from the implementation section of the guide, and should be used in cooperation with the whole document.* The full design guide is available from the ASHRAE website, Advanced Energy Design Guide for Small Office Buildings .

Roll-up or sliding doors are recommended to have R-4.75 rigid insulation. The center of section U-factor is degraded due to thermal bridging at the door and section edges.
