Energy Efficiency Opportunities in Highway Lodging Buildings: Development of 50 Energy Savings Design Technology Packages

摘要

This paper presents the process, methodology, and assumptions for development of thern50% Energy Savings Design Technology Packages for Highway Lodging Buildings, a designrnguidance document that provides specific recommendations for achieving 50% site energyrnsavings in roadside motels (highway lodging) above the requirements of ANSI/ASHRAE/IESNArnStandard 90.1-2004. This 50% solution represents a further step toward realization of the U.S.rnDepartment of Energy’s net-zero energy building goal, and exceeds the 30% savings in thernAdvanced Energy Design Guide series (upon which this work was built). This work can serve asrnthe technical feasibility study for the development of a 50% saving Advanced Energy DesignrnGuide for Highway Lodging, and thus should greatly expedite the development process.rnThe design technology package provides user-friendly design assistance to designers,rndevelopers, and owners of highway lodging properties. It is intended to encourage energyefficientrndesign by providing prescriptive energy-efficiency recommendations for each climaternzone in the United States and to help new construction of highway lodging attain the 50% energyrnsavings target.rnThis paper describes the steps that were taken to demonstrate the technical feasibility ofrnachieving a 50% reduction in whole-building energy use with practical and commerciallyrnavailable technologies. The energy analysis results are presented, indicating the recommendedrnenergy-efficient measures achieved a national-weighted average energy savings of 55%, relativernto Standard 90.1-2004. The cost-effectiveness of the recommended technology package isrnevaluated, and the result shows an average simple payback of 11.3 years. Finally, suggestions forrnimproving future 50% (or beyond) design technology package work are discussed.
