Decision Guides for Plug and Process Load Controls
PPLs account for an increasingly large percentage of commercial building energy use. The primary energy use associated with PPLs is projected to grow from 30% to 35% of total commercial building energy use between 2010 and 2025 because the number and energy intensity of plug-in devices continue to increase. This is due to the wide range of U.S. commercial building types, uses, sizes, and vintages, PPL energy consumption can range from 10% in warehouses to nearly 60% in food sales. The decision guides found in this resource were created to help building owners find the right control strategy for PPLs in their buildings. The guides are developed for different building types and outline the costs, potential savings, complexities, and user friendliness of various control strategies and their applications to each building type. The guides also aim to help building owners determine whether a control is appropriate for particular project applications such as staged retrofit projects, whole-building retrofits, new construction projects, and projects that involve tenants and landlords. Lastly, the guides provide links to additional resources that can further help building owners assess and reduce the energy use that is associated with PPLs, find rebates for PPL control measures, and procure the right control types for their building equipment.
