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.

A solar ready building is engineered and designed for solar installation, even if the solar installation does not happen at the time of construction. The solar ready design features, if considered early in the design process, are typically low or no cost. Attention to building orientation, available roof space, roof type, and other features is key to designing solar ready buildings.
This guide was created to help healthcare facility decision-makers plan, design, and implement energy improvement projects in their facilities. It was designed with energy managers in mind, and presents practical guidance for kick-starting the process and maintaining momentum throughout the project life cycle.
The Advanced Energy Retrofit Guide for Grocery Stores was created to help grocery store decision makers plan, design, and implement energy improvement projects in their facilities. It was designed with energy managers in mind, and presents practical guidance for kick-starting the process and maintaining momentum throughout the project life cycle.
K–12 schools are ideal candidates to lead the market shift from buildings that consume energy to buildings that produce as much renewable energy as they use. There are now resources to guide owners and project teams as they make the shift to these “zero energy” buildings, notably the Advanced Energy Design Guide for K–12 School Buildings: Achieving Zero Energy (K–12 ZE AEDG).
This 10-page paper provides a concise overview of the K–12 ZE AEDG (200 pages), as well as a nice explanation of the energy modeling and analysis methodology used to create the Design Guide.
This guide provides user-friendly guidance for achieving a net zero energy K-12 school building. It includes a set of energy performance targets for all climate zones. Strategies on how to achieve these energy targets are provided throughout the guide and include setting measurable goals, hiring design teams committed to that goal, using energy simulation throughout the design and construction process, and being aware of how process decisions affect energy usage.
The how-to tips address specific project aspects-building and site planning, envelope, daylighting, electric lighting, plug loads, kitchens and food service, water heating, HVAC, and renewable energy generation. Each section contains multiple tips that move the design incrementally toward the zero energy goal. Case studies and technical examples show how the energy goals are achievable at typical construction budgets as well as demonstrate the technologies in real-world applications.
The intended audience of this guide includes educators, school administrators, architects, design engineers, energy modelers, contractors, facility managers, and building operations staff.
