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 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.
This guide primarily applies to facility managers and energy managers of large existing office buildings larger than 100,000 square feet, but also includes considerations for small and medium office buildings. By presenting general project planning guidance as well as financial payback metrics for the most common energy efficiency measures, this guide provides a practical roadmap for effectively planning and implementing performance improvements for existing buildings.
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.
Bank of America partnered with DOE's Commercial Building Partnerships (CBP) Program to develop and implement solutions to build a new bank branch in Punta Gorda, Florida, with a goal of being at least 50% below ASHRAE Standard 90.1-2004. The branch opened in October 2011 and achieved actual energy savings of 47%.
Southface developed this Campus Benchmarking Guide to help colleges and universities assess the energy and water usage of both small and large buildings and compare them to ENERGY STAR’s index of average energy usage for over 80 relevant building types. This enables the buildings with the greatest opportunities for savings to be easily identified regardless of size.
Article in the Whole Building Design Guide about the uses and features of metal roofs that meet "cool roof" standards.
The purpose of the service hot water recovery calculator is to provide a tool for a refrigeration designer to use in estimating the potential energy savings of capturing heat from a refrigeration system for use in pre-heating a domestic hot water system. This tool assumes that only the superheated vapor portion of the refrigeration system's total heat of rejection will be captured with a heat recovery tank. Tank-type heat reclaim systems are one of the most common methods of heat recovery due to both their cost effectiveness and that large volumes of hot water are often consumed in supermarkets on a daily basis. This spreadsheet is intended for use by refrigeration or mechanical designers for rapid yet robust calculation of energy performance. This calculator assumes that the refrigeration input of the hot water recovery tank operates in series between the refrigeration compressor rack and condenser to capture superheat from compressors prior to condensing. This calculator also assumes that the domestic cold water supply is the only input to the hot water recovery tank and that hot water recirculation is not present or is returned to the service hot water system after the hot water recovery tank.
This spreadsheet is designed for use with the Refrigeration Playbook: Heat Reclaim report (www.nrel.gov/docs/fy15osti/63786.pdf). Please note that this calculator is not currently approved for use on Mac computers.
This project was part of the U.S. Department of Energy’s Commercial Buildings Partnerships. Companies and organizations, selected through a competitive process, teamed with DOE, national laboratory staff, and technical experts from the private sector who provided technical expertise to explore energy-saving ideas and strategies that were applied to specific building projects and that could be replicated across the market. The work presented here focuses on reducing energy use in supermarkets.
