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.
The Advanced Energy Design Guide for Small Retail Buildings (AEDG-SR; the Guide) is intended to provide a simple approach for contractors and designers who create retail buildings up to 20,000 ft2. Application of the recommendations in the Guide should result in small retail buildings with 30% energy savings when compared to those same retail buildings designed to the minimum requirements of ANSI/ASHRAE/IESNA Standard 90.1-1999.
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.
