Retail buildings in the U.S. are second only to office buildings in total energy consumption and represent approximately 13% of energy use in commercial buildings nationwide. The Advanced Energy Retrofit Guide for Retail Buildings presents general project planning guidance as well as more detailed descriptions and financial payback metrics for the most important and relevant energy efficiency measures to provide a practical roadmap for effectively planning and implementing performance improvements in existing buildings. This guide is primarily designed for facility managers and energy managers of existing retail buildings of all sizes.

This guide was created to help healthcare facility decision-makers plan, design, and implement energy improvement projects in their facilities. It was designed with energy managers in mind, and presents practical guidance for kick-starting the process and maintaining momentum throughout the project life cycle.
The Advanced Energy Retrofit Guide for Grocery Stores was created to help grocery store decision makers plan, design, and implement energy improvement projects in their facilities. It was designed with energy managers in mind, and presents practical guidance for kick-starting the process and maintaining momentum throughout the project life cycle.
Case study on how Fontana Unified School District in southern California used grant money to install 201 high-efficiency Carrier rooftop units (RTUs) in 30 buildings across four schools, resulting in $214,000 saved per year.
Case study on how Arby's Restaurant Group's innovative approach to rooftop unit (RTU) management garnered them $287,000 and 2.9 million kWh in annual savings.
It is possible for K–12 new construction projects to achieve zero energy in all climate zones throughout the continental United States. This study includes:
• Energy use intensity (EUI) targets for all climate zones (Tables 23-26) to help users set goals for their zero energy school designs.
• A pathway for how to achieve these EUIs by climate zone, including values for the building envelope, fenestration, lighting systems (including electrical lights and daylighting), HVAC systems, building automation and controls, outdoor air treatment, and SWH.
• Case studies of actual K–12 school applications which demonstrate the business case and practicality of achieving zero energy schools.
This feasibility study was developed with input and guidance from a panel of industry experts. In many ways, this feasibility study is a simple interface to a complex analysis performed using EnergyPlus energy modeling. The combination of strategies contained in a single table should help facilitate increased energy efficiency in new buildings.
NREL experienced a significant increase in employees and facilities on our 327-acre main campus in Golden, Colorado over the past five years. To support this growth, researchers developed and demonstrated a new building acquisition method that successfully integrates energy efficiency requirements into the design-build requests for proposals and contracts. We piloted this energy performance based design-build process with our first new construction project in 2008. We have since replicated and evolved the process for large office buildings, a smart grid research laboratory, a supercomputer, a parking structure, and a cafeteria. Each project incorporated aggressive efficiency strategies using contractual energy use requirements in the design-build contracts, all on typical construction budgets. We have found that when energy efficiency is a core project requirement as defined at the beginning of a project, innovative design-build teams can integrate the most cost effective and high performance efficiency strategies on typical construction budgets. When the design-build contract includes measurable energy requirements and is set up to incentivize design-build teams to focus on achieving high performance in actual operations, owners can now expect their facilities to perform. As NREL completed the new construction in 2013, we have documented our best practices in training materials and a how-to guide so that other owners and owner’s representatives can replicate our successes and learn from our experiences in attaining market viable, world-class energy performance in the built environment.
The Advanced Energy Retrofit Guide for K-12 Schools is one of five retrofit guides commissioned by the U.S. Department of Energy. By presenting general project planning guidance as well as more detailed descriptions and financial payback metrics for the most important and relevant energy efficiency measures, the guides provide a practical roadmap for effectively planning and implementing performance improvements in existing buildings. The K-12 Schools guide provides convenient and practical guidance for making cost-effective energy efficiency improvements in public, private, and parochial schools.
