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.

Momentum behind zero energy building design and construction is increasing, presenting a tremendous opportunity for advancing energy performance in the commercial building industry. At the same time, there is a lingering perception that zero energy buildings must be cost prohibitive or limited to showcase projects. Fortunately, an increasing number of projects are demonstrating that high performance can be achieved within typical budgets. This factsheet highlights replicable, recommended strategies for achieving high performance on a budget, based on experiences from past projects.
