The Advanced Energy Design Guide (AEDG) for Small Office Buildings, 30% series, seeks to achieve 30% savings over ASHRAE Standard 90.1-1999. This guide focuses on improvements to small office buildings, less than 20,000ft². The recommendations in this article are adapted from the implementation section of the guide and focus on insulation entirely above-deck; metal buildings; attics and other roofs; single-rafter roofs.
