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 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.
The rooftop unit (RTU) decision tree can be used for preliminary screening for replacement of RTU units with more efficient units. This decision tree organizes RTUs into bins for “retrofit,” “replacement,” “no action,” or “needs further analysis.”
The rooftop unit (RTU) Field Evaluation Checklist is intended to help identify damage, dysfunction, or degradation that requires more than routine maintenance. The checklist should be used to conduct a visual-based field evaluation to further refine the preliminary analysis.
The rooftop unit inventory spreadsheet can be used to gather basic RTU information, such as number, size, age, and general condition. The detailed fields in the spreadsheet can be used to gather additional information, such as controls, usage patterns, and features for additional analysis of the RTUs identified for retrofit, replacement, or further analysis.
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.
Plug and process loads in commercial buildings account for 5% of U.S. primary energy consumption. Minimizing these loads is a primary challenge in the design and operation of an energy-efficient building.
Plug and process loads (PPLs) in commercial buildings account for almost 5% of U.S. primary energy consumption. Minimizing these loads is a primary challenge in the design and operation of an energy-efficient building. PPLs are not related to general lighting, heating, ventilation, cooling, and water heating, and typically do not provide comfort to the occupants. They use an increasingly large fraction of the building energy use pie because the number and variety of electrical devices have increased along with building system efficiency. Reducing PPLs is difficult because energy efficiency opportunities and the equipment needed to address PPL energy use in office spaces are poorly understood.
Through the Better Buildings Workforce Guidelines, industry now has national guidelines from which to develop high quality and nationally recognized training and certification programs, helping to address challenges found in the energy efficiency workforce with quality, consistency, and scalability across certification and certificate programs.
The Department of Energy worked with the National Institute of Building Sciences (NIBS) and industry stakeholders to develop the Better Buildings Workforce Guidelines, voluntary national guidelines to improve the quality and consistency of commercial building workforce credentials for four key energy-related jobs: Building Energy Auditor, Building Commissioning Professional, Building Operations Professional, Energy Manager.
The Better Buildings Workforce Guidelines aligns all elements of the Better Buildings Workforce Framework, with the goal of supporting high-quality industry and government-recognized credentials for 4 key commercial energy-related job titles. Together, the Job Task Analyses (JTA) documents and the certification schemes comprise the content of the voluntary, industry-developed, and industry and government-recognized Better Buildings Workforce Guidelines.
This Fact Sheet provides an overview of the Better Buildings Workforce Guidelines project. The Department of Energy (DOE) and the National Institute of Building Sciences (NIBS) are working with industry stakeholders to develop voluntary national guidelines that will improve the quality and consistency of commercial building workforce training and certification programs for five key energy-related jobs.
