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.

Bank of America partnered with DOE's Commercial Building Partnerships (CBP) Program to develop and implement solutions to build a new bank branch in Punta Gorda, Florida, with a goal of being at least 50% below ASHRAE Standard 90.1-2004. The branch opened in October 2011 and achieved actual energy savings of 47%.
PNC Financial Services partnered with DOE's Commercial Building Partnerships (CBP) Program to develop and implement solutions to retrofit its existing Singer Island, Florida, branch to reduce energy consumption by at least 30% versus ASHRAE Standard 90.1-2004. Construction was completed in January 2012.
Kohl’s partnered with the Department of Energy (DOE) to develop and implement solutions to retrofit existing buildings to reduce annual energy consumption by at least 30% versus requirements set by Energy Standard 90.1-2004 of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), the American National Standards Institute (ANSI), and the Illuminating Engineering Society of America (IESNA) as part of DOE’s Commercial Building Partnership (CBP) program. The National Renewable Energy Laboratory (NREL) provided technical expertise in support of this DOE program. Kohl’s retrofitted a 17 year-old, single-story 87,000 sq. ft store in Niles, Ohio. Kohl’s also designated the store as a DOE Better Buildings Challenge showcase store.
This article, published in High Performance Buildings Magazine, presents the process used for delivering NREL's Research Support Facility (RSF) as a replicable blueprint to achieve a large reduction in building energy use and to adopt a net zero energy approach for large-scale commercial buildings (ZEB) without increasing cost.
The General Service Administration's (GSA) Green Proving Ground (GPG) program worked with a team from the National Renewable Energy Laboratory (NREL) to identify buildings with office setups and equipment distributions typical of the wider GSA building stock. Eight buildings from GSA’s Mid-Atlantic Region, where plug loads average 21%, were selected. In each building, approximately 12 standard power strips with no control capability (the incumbent technology) were replaced with APSs, which monitored and provided power to an array of devices. More than 295 devices were monitored during the study, which consisted of three separate test periods, each four weeks in length. All buildings selected had workstation power management in place.
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.
