Energy Efficiency Guide for Existing Commercial Buildings
Originally presented on December 12, 2011 to US Department of Energy – you can see a 24 slide executive summary that outlines the guide development, content and recommendations for the Existing Buildings Technical Implementation Guide.
This guide is the second in a series of planned Energy Efficient Guides for Existing Commercial Buildings (EEG-EB) developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) in collaboration with the American Institute of Architects (AIA), the Illuminating Engineering Society of North America (IES), and the U.S. Green Building Council (USGBC), and supported by the U.S. Department of Energy (DOE). While the first guide in the series provided the business case for improving energy efficiency, this guide provides technical guidance on how to increase a building’s energy efficiency.
This guide is intended for building engineers and managers and assumes a working technical knowledge of building systems both generally and for the reader’s specific building. The guide demonstrates ways to measure a building’s energy efficiency, track that efficiency, develop an energy efficiency plan, and provides guidance on implementing the developed plan. The goal is to provide clear and easily understood technical guidance for energy upgrades, retrofits, and renovations, by which building engineers and managers can achieve at least a 30% improvement in energy performance relative to a range of benchmark energy utilization indexes (EUIs). The document provides practical means and methods for planning, executing, and monitoring an effective program, based on widely available technical strategies and technologies.
The Energy Efficiency Guide for Existing Commercial Buildings: The Business Case for Building Owners and Managers
This is the first in a series of Energy Efficiency Guides (EEGs) for existing buildings and is aimed at providing the business case for energy efficiency to building owners and managers. The Guide provides the rationale for making economic decisions related to improving and sustaining energy efficiency in existing buildings. The goal is to enable building owners to undertake the processes for evaluating current operations and do the economic analysis of options for improvement. The Guide demonstrates ways to benchmark performance against comparable buildings; illustrates ways under which energy use and cost can be reduced by at least 30%; and details how this can be done, all while minimizing capital investment and maximizing return on investment. It further identifies additional measures that can achieve even greater energy efficiencies and cost savings in economical ways.
