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.

This presentation discusses the importance of selecting a project delivery method that balances performance, best value, and cost savings.
The Research Support Facility complex (RSF, RSF II, parking garage, and associated site lighting) was designed to produce more on-site renewable energy than it uses over the course of a typical weather year, when accounted for at the site. To date, the end use performance monitoring and verification suggests that when the RSF complex is fully built out, we will meet the annual energy use goals. Continued performance monitoring and occupant education are required to ensure annual energy use goals will continue to be met.
This document provides facility managers and building owners with an introduction to measurement and verification (M&V) methods to estimate energy and cost savings of rooftop units replacement or retrofit projects. The M&V methods presented here are helpful in estimating paybacks to justify future projects.
Dollars saved through energy efficiency can directly impact your bottom line. Whether you are planning for a major renovation or upgrading individual pieces of building equipment, these improvements can help reduce operating costs, save on utility bills, and boost profits. This fact sheet provides a guide for small businesses to find the resources to increase the energy efficiency of their buildings.
The energy efficiency community has worked hard to engage lenders and consumers in what is estimated by the Rockefeller Foundation and Deutsche Bank to be a $279 billion market for energy efficiency investment. Great advances have been made in the federal and public sector’s program development arena, yet private sector transaction volume remains frustratingly low. In an effort to understand nuanced obstacles to market participation, ACEEE and Energi Insurance Services convened a group of small to mid-size lenders to discuss opportunities for increasing both lender and consumer participation in the energy efficiency space. Lender representation spanned state and local commercial banks, community banks, community development financial institutions (CDFIs), credit unions, and “green” lenders. This paper presents the obstacles identified in the convening and offers recommendations to the energy efficiency community to foster growth in the market for energy efficiency financing.
This presentation Session II from the RSF Workshop discusses the performance-based design-build process, which was used to procure and construct the Research Support Facility.
