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.

This publication details the design, implementation strategies, and continuous performance monitoring of NREL's Research Support Facility data center.
This case study details the design and operations of the National Renewable Energy Laboratory (NREL) Research Support Facility data center and its contributions to energy efficiency.
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.
This case study describes National Renewable Energy Laboratory efforts design a world-class, energy-efficient data center to support the operations of a new office building. These efforts resulted in a highly efficient data center that demonstrated considerable energy savings in its first 11 months of operations. Using legacy data center performance as a baseline, the new facility cut energy use by nearly 1.45 million kWh, delivering cost savings of approximately $82,000.
"This paper discusses the evidence regarding daylighting and student performance and development, and presents four case studies of schools that have cost effectively implemented daylighting into their buildings."
This study expands and validates previous research by Heschong Mahone Group that found a statistical correlation between the amount of daylight in elementary school classrooms and student performance. The researchers reanalyzed student performance data from two school districts to answer questions raised by the previous study. The results are consistent with the original findings and affirm that daylight has a positive and highly significant association with improved student performance.
7x7x7: Design Energy Water is an innovative program by the Division of the State Architect that encouraged California school districts to develop long-range master plans that reduce energy and water consumption on campuses and improve the quality of educational spaces. The State Architect engages seven architectural firms to develop seven conceptual case studies that reduce school energy and water consumption and result in better learning environments on seven different types of campuses (six K-12 schools and a community college). The seven campuses are representative of typical building types from different eras constructed across California’s varied climate zones. The purpose and primary goal of this program is to enable all existing K-14 facilities to be zero energy by 2030.
This case study describes a successful zero energy school project in Utah.
On the night of May 4, 2007 an EF5 tornado 1.7 miles wide ravaged Greensburg, Kansas, destroying 95% of the city's homes and businesses. In the wake of the disaster, it became apparent that changes would need to occur to sustain the town for future generations. The Greensburg School District selected BNIM Architects to provide comprehensive design services for new school facilities.
In direct alignment with the town's Sustainable Comprehensive Master Plan, the USD decided to rebuild to LEED Platinum. This decision led the way for the city, which later mandated that all public buildings attain a Platinum rating. This K–12 facility combines the resources of three rural community school districts into a single facility, thereby right-sizing at a regional scale.
