We are indebted to a number of retailers and building industry professionals for taking the time to review our analysis assumptions and earlier versions of this report. Jim Kirk of A&P Grocery Stores, Kathy Loftus of Whole Foods, and Scott Williams of Target, all members of the Retailer Energy Alliance, commented on our prototype and energy design measure (EDM) model assumptions based on their companies' experiences and standard practices. Don Zerrip, Ben Butler, and H. J. Enck of CxGBS; Tim A. Speller of Speller Energy Consulting; and Thomas H. Phoenix of Moser Mayer Phoenix Associates reviewed an earlier draft of this report.We extend our thanks to our colleagues Larry Brackney and Kristin Field for conducting formal internal reviews of this document, and to Stefanie Woodward for editing assistance.Several other National Renewable Energy Laboratory (NREL) colleagues provided valuable guidance and information during the modeling process, either directly or through their past work. Ian Doebber and Michael Deru contributed insights gained through their work with grocery store owners and retailers. Jennifer Scheib and Rob Guglielmetti provided electric lighting and daylighting EDM data. We would also like to thank Don Shirey of the Florida Solar Energy Commission, and Hugh Henderson of CDH Energy Corporation for responding to several specific questions; and Merle McBride acting on behalf of the ASHRAE Standard 90.1 Envelope Subcommittee for providing recent cost data for mass wall constructions.Tens of thousands of EnergyPlus simulations were run for this report. This would not have been possible without the support of the NREL High Performance Computing Center managed by Wesley Jones and Jim Albin.Finally, a number of our colleagues in the Commercial Buildings Group helped set up and run our analysis and results extraction routines. We would especially like to thank Dan Macumber, Nicholas Long, Eric Bonnema, and Kyle Benne for programming assistance; and Brent Griffith, Dan Macumber, Kyle Benne, Michael Deru, and Ian Doebber for sharing their computing resources.ii Executive SummaryThis Technical Support Document (TSD) was developed by the Commercial Buildings Group at NREL, under the direction of the DOE Building Technologies Program.

This Technical Support Document (TSD) describes the process, methodology and assumptions for development of the 50% Energy Savings Design Technology Packages for Highway Lodging Buildings.This design guidance document provides specific recommendations for achieving 50% energy savings in highway lodging properties over the energy-efficiency levels contained in ANSI/ASHRAE/IESNA Standard 90.1-2004 (ANSI/ASHRAE/IESNA 2004a). These 50% savings design packages represent a further significant step towards realization of the U.S. Department of Energy's (DOE) net-zero energy building goal for new construction by the year 2025. DOE has previously supported the development of a series of 30% energy savings design guides, which were developed by a partnership of organizations, including the American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc. (ASHRAE), the American Institute of Architects (AIA), the Illuminating Engineering Society of North America (IESNA), the United States Green Buildings Council (USGBC), as well as DOE 1 .This report provides recommendations and user-friendly design assistance to designers, developers, and owners of highway lodging properties and is intended to encourage steady progress towards net-zero energy performance in these buildings. The design package provides prescriptive recommendation packages that are capable of reaching the 50% energy savings target for each climate zone, thereby easing the burden of the design and construction of highway lodging with exemplary energy performance.To develop the set of energy efficiency measure recommendations that meet, or exceed, the 50% goal, we used a highway lodging prototype, adapted from previous work for achieving 30% savings in the Advanced Energy Design Guide for Highway Lodging Buildings (AEDG-HL), to represent this class of buildings.We created baseline models from the prototype that are minimally code-compliant with ASHRAE 90.1-2004, and advanced models based on the recommended energy-efficient technologies. To determine the energy savings at different climate locations, we performed EnergyPlus simulation analyses. The simulation approach used is documented in this TSD, along with the characteristics of the prototype and assumptions of the baseline and advanced models.Finally, we assessed the cost effectiveness of the energy-efficient technologies recommended in the design package using the simple payback period method.Prescriptive packages of recommendations presented in the design package by climate zone include enhanced envelope technologies, interior and exterior lighting technologies, heating, ventilating, and airconditioning (HVAC) and service water heating (SWH) technologies, and miscellaneous appliance technologies. Final energy efficiency recommendations for each climate zone are included, along with the results of the energy simulations indicating a national-weighted average energy savings over all buildings and climates of 55.5% in comparison with the Standard 90.1-2004 as baseline.A cost estimate of the re...

“…Our prototype store is 50,000 ft 2 (4,645 m 2 ), as this size lies well between 20,000 ft 2 and 100,000 ft 2 and is near the area-weighted mean off the 33 medium-sized CBECS retail stores (see Figure 3-3). Liu et al (2006) assumed that merchandising accounted for 70% of the floor area in their prototype stores. The rest is allocated to active storage (20%), office (5%) and other use (5%) spaces.…”

A number of colleagues made this work possible. The authors greatly appreciate the assistance of Brent Griffith and the NREL EnergyPlus analysis and modeling team. Their simulation development and support allowed us to evaluate a variety of energy efficiency technologies. We would also like to thank NREL's High Performance Computing Center's Wesley Jones and Jim Albin for their support in providing dedicated Linux cluster nodes for the simulations needed for the analysis. Finally, we extend our thanks to those who helped edit and review the document: Stefanie Woodward, Michael Deru, and Ian Doebber (all of NREL). iv Executive SummaryThis report documents technical analysis aimed at providing design guidance that achieves wholebuilding energy savings of at least 50% over ASHRAE Standard 90.1-2004 in medium-sized retail buildings. It represents an initial step towards determining how to provide design guidance for energy savings targets larger than 30%, and was developed by the Commercial Buildings Section at the National Renewable Energy Laboratory (NREL), under the direction of the DOE Building Technologies Program.This report:• Documents the modeling and integrated analysis methods used to identify cost-effective sets of recommendations for different locations and business activities.• Demonstrates sets of recommendations that meet, or exceed, the 50% goal. There are forty eight sets of recommendations, one for each combination of sixteen climate zones and three levels of unregulated plug loads.This technical support document (TSD), along with a sister document for grocery stores (Hale et al. 2008), also evaluates the possibility of compiling a 50% Advanced Energy Design Guide (AEDG) in the tradition of the 30% AEDGs available through the American Society of Heating, Refrigerating, and AirConditioning Engineers (ASHRAE) and developed by an inter-organizational committee structure. In particular, we comment on how design guidance should be developed and presented in the next round of 50% TSDs for deployment as AEDGs. MethodologyBecause it is important to account for energy interactions between building subsystems, NREL used EnergyPlus to model the predicted energy performance of baseline buildings and low-energy buildings to verify that the goal of 50% energy savings can be met. EnergyPlus was selected because it computes building energy use based on the interaction of the climate, building form and fabric, internal gains, HVAC systems, and renewable energy systems. Percent energy savings are based on a minimally codecompliant building as described in Appendix G of ASHRAE 90.1-2004, and whole-building, net site energy use intensity (EUI): the amount of energy a building uses for both regulated and unregulated loads, minus any renewable energy generated within its footprint, normalized by building area.The following steps were used to determine 50% savings:• Define architectural-program characteristics (design aspects not addressed by ASHRAE 90.1-2004) for typical retail stores, thereby defining prototype models....
