Abstract

This paper summarizes the results of a recent study assessing the energy-related characteristics of over 160 buildings planned for construction in 2001 and beyond from across the United States. The data used in the assessment includes over 130 different construction characteristics (e.g., envelope R-values and construction type, room types and area, window and door types, equipment types and capacities, HVAC systems and zoning, lighting power densities and lighting technologies) from a variety of different building types. This information provides a window into current construction practice on a national basis. These data have been used to evaluate typical energy code compliance across the nation using the COMcheck-EZ™ energy standard compliance software tool. The results of the evaluation show how closely new construction across the nation is to meeting current and recently adopted energy codes such as ANSI/ASHRAE/IESNA 90.1-1999 and beyond.
