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.

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.

"With a higher efficiency and increased controllability, the VRF system can help achieve a sustainable design. Unfortunately, the design of VRF systems is more complicated and requires additional work compared to designing a conventional direct expansion (DX) system. This course provides an overview of VRF system technology."

This guide discusses how to achieve greater energy efficiency through occupancy behavior analysis and energy auditing to create targeted and strategic behavior change.

This Advanced Energy Design Guide is for typical hotels found along highways having up to 80 rooms, generally four stories or less, that use unitary heating and air-conditioning equipment, which represent a significant amount of commercial hotel space in the U.S. Application of the recommendations in the Guide should result in hotels with 30% energy savings when compared to those same hotels designed to the minimum requirements of ANSI/ASHRAE/IESNA Standard 90.1-1999, Energy Standard for Buildings Except Low-Rise Residential Buildings.

The Advanced Energy Design Guide for K-12 School Buildings is the second in a series of Advanced Energy Design Guide (AEDG) publications designed to provide strategies and recommendations for achieving 50% energy savings over the minimum code requirements of ANSI/ASHRAE/IESNA Standard 90.1-2004, Energy Standard for Buildings Except Low-Rise Residential Buildings.

The Advanced Energy Design Guide for Large Hospitals shows that existing reliable technologies and design philosophies can be used to reduce energy use in large hospitals by up to 50% of ANSI/ASHRAE/IESNA Standard 90.1-2004 recommendations.

The Advanced Energy Design Guide for Medium to Big Box Retail Buildings is designed to provide recommendations to achieve 50% energy savings for retail buildings 20,000 to 100,000 ft2. Energy costs are typically the second-highest operating expense for a retailer, so use of this guide can help in creating a cost-effective design for new retail buildings and major renovations that will consume substantially less energy compared to the minimum code-compliant design and that will result in lower operating costs.

The Advanced Energy Design Guide for Small Hospitals and Healthcare Facilities can help in the design of new healthcare facilities that are 30% more energy efficient than current industry standards using ANSI/ASHRAE/IESNA Standard 90.1-1999 as a benchmark. This saves energy but also supports the other design goals important to healthcare facilities: to improve the patient experience, enhance the healing environment, increase staff retention, lower construction and operating costs, contribute to an environmentally conscious building design, and improve the bottom-line performance of the healthcare facility.
