Advanced Energy Design Guides
ASHRAE has completed Advanced Energy Design Guides (AEDG) for Small Office (SO) Buildings, Small Retail (SR) Buildings, and K-12 School Buildings. These guides, intended as companion "above code" documents for ANSI/ASHRAE/IESNA Standard 90.1-1999, demonstrate how these buildings may be built 30% more energy efficient than the standard. ASHRAE is also working on an additional guide for warehouses.
