This guide explains the benefits and process of building commissioning thereby providing owners and other stakeholders a tool to improve building efficiency and operation. It is intended to be a resource, as well as a call to action, for building owners and facility managers who want to verify their buildings are not only operating as originally intended, but also as efficiently as possible. Commissioning of new construction and major renovations is the primary focus, although commissioning of existing buildings is also briefly discussed as well.

This guide provides an overview of the different energy audit options available and information on how to select an energy auditor.
This guide describes the benefits offered by energy service companies (ESCOs) and the things to consider when selecting and contracting with your provider. The appendix document is also available and contains solicitation and contracting samples.
These appendices contain solicitation and contract samples for working with energy service contractors (ESCOs) and go with the previously published, "A Guide to Performance Contracting with ESCOs".
The purpose of this handbook is to furnish guidance for planning and conducting a highperformance building charrette, sometimes called a "greening charrette." The handbook answers typical questions such as, "What is a charrette?", "Why conduct a charrette?", "What topics should we cover?", "Whom should we invite?" and "What happens after the charrette?". Owners, design team leaders, site planners, state energy office staff, and others who believe a charrette will benefit their projects will find the handbook helpful.
This guide discusses how to achieve greater energy efficiency through occupancy behavior analysis and energy auditing to create targeted and strategic behavior change.
The Advanced Energy Design Guide for Small Warehouses and Self-Storage Buildings (AEDG-WHSE; the Guide) is intended to provide a simple approach for contractors and designers who create warehouses. Application of the recommendations in the Guide should result in warehouses with 30% energy savings when compared to those same warehouses designed to the minimum requirements of ANSI/ASHRAE/IESNA Standard 90.1-1999, Energy Standard for Buildings Except Low-Rise Residential Buildings.
It is still early in the collection and analysis of energy performance data, but it is already clear that high-performance commercial buildings—some "almost net-zero buildings"—can be constructed cost effectively, providing productive environments for occupants, reducing operating costs, and enhancing the competitiveness of commercial properties.
This report summarizes the findings from research conducted at NREL to assess the technical potential for zero-energy building technologies and practices to reduce the impact of commercial buildings on the U.S. energy system. Commercial buildings currently account for 18% of annual U.S. energy consumption, and energy use is growing along with overall floor area. Reducing the energy use of this sector will require aggressive research goals and rapid implementation of the research results.
This paper describes efforts to develop a computerized tool that can rapidly execute and evaluate many building energy simulations. Building energy simulations are often used for trial-and-error evaluation of “what-if” options in buildingdesign—a limited search for an optimal solution, or “optimization.” Computerized searching has the potential to automate the input and output, evaluate many options, and perform enough simulations to account for the complex interactions among combinations of options.
