This Advanced Energy Design Guide is for typical hotels found along highways having up to 80 rooms, generally four stories or less, that use unitary heating and air-conditioning equipment, which represent a significant amount of commercial hotel space in the U.S. Application of the recommendations in the Guide should result in hotels with 30% energy savings when compared to those same hotels designed to the minimum requirements of ANSI/ASHRAE/IESNA Standard 90.1-1999, Energy Standard for Buildings Except Low-Rise Residential Buildings.

This paper introduces a classification system for net-zero energy buildings (ZEB) based on the renewable sources a building uses.
