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.
In typical computer centers you can feel the energy consumption from racks of servers radiating heat, while icy air blows through the room to cool them. NREL’s fully contained hot and cold aisle data center configuration minimizes this problem. The configuration includes effective air-side economizer cooling with an evaporative boost when needed.
This document highlights the key accomplishments in Green IT of the 17 DOE labs.
This fact sheet summarizes recommendations for designing elementary, middle, and high school buildings that will result in 50% less energy use than conventional new schools built to minimum code requirements. The recommendations are drawn from the Advanced Energy Design Guide for K-12 School Buildings, an ASHRAE publication that provides comprehensive recommendations for designing low-energy-use school buildings.
Designed as a stand-alone document, this fact sheet provides key principles and a set of prescriptive design recommendations appropriate for smaller schools with insufficient budgets to fully implement best practices for integrated design and optimized performance. The recommendations have undergone a thorough analysis and review process through ASHRAE, and have been deemed an easily replicable combination of measures to achieve 50% savings in K-12 schools.
