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 report discusses miscellaneous electrical loads, which are building loads that are not related to general lighting, heating, ventilation, cooling, and water heating, and typically do not provide comfort to the occupants. MELs in commercial buildings account for almost 5% of U.S. primary energy consumption.
The Research Support Facility was designed with energy efficiency and sustainability in mind. Many of its innovative technologies use passive and active processes to provide energy for its operations, such as electricity, heating, and cooling. The goal of this unique office building is to reach net zero energy use by engaging staff in best energy practices.
This eight-page fact sheet helps employees moving to the RSF navigate NREL's changing landscape. This brochure provides getting up and running, building access, emergencies, shuttle service, RTD buses, parking locations, parking passes, exceptions to off-site parking, conference rooms and huddle rooms, balconies, elevators, lunchroom, quiet rooms, smoking, iGo Power Smart Tower, and supporting RSF's net zero energy mission.
The U.S. Department of Energy’s Research Support Facility at the National Renewable Energy Laboratory is a new 222,000 square foot office building. It achieves the U.S. Green Building Council’s Leadership in Energy and Environmental Design New Construction Platinum certification, and is expected to become the largest net-zero energy office building in the nation.
This fact sheet published by the National Renewable Energy Laboratory discusses the lab's newest building, the Research Support Facility (RSF). The RSF is a showcase for ultra-efficient workplaces. Various renewable energy and energy efficiency features have been employed so that the building achieves a Leadership in Energy and Environmental Design Platinum rating from the U.S. Green Building Council.
McGraw Hill Construction Continuing Education Article December 2010 - This article discusses the energy efficiency and cost competitiveness of the Research Support Facility.
The Research Support Facility is designed to be one of the world's largest net-zero energy buildings. It incorporates new technologies and techniques and draws on centuries-old concepts. Its operable windows allow natural ventilation. It monitors indoor and outdoor temperatures and displays messages on each computer about opening or closing windows.
At the time this Wall Street Journal article was published, the National Renewable Energy Laboratory was midway through construction of a $64 million project to be the greenest office building in the nation. This article explores efforts by architects and engineers who spent hundreds of hours calculating the energy use of every aspect of the building, from the elevator to the exit signs.
The U.S. Department of Energy hopes lessons learned from the Research Support Facility will help guide green-construction practices around the world. Outside experts in efficient construction point out that some of the technology used at NREL is best suited for high-sunlight, low-humidity climates such as Colorado and would not work nearly as well elsewhere. The building also demands a lot from its employees, who must adjust to fluctuating temperatures throughout the day and pop up from their desks to open and shut windows; a workforce less dedicated to energy efficiency might rebel.
