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.

Article in the Whole Building Design Guide about the uses and features of metal roofs that meet "cool roof" standards.
Low energy or high-performance buildings form a vital component in the sustainable future of building design and construction. Rigorous integrated daylighting design and simulation will be critical to their success as energy efficiency becomes a requirement, because electric lighting usually represents a large fraction of the energy consumed. We present the process and tools used to design the lighting systems in the newest building at the National Renewable Energy Laboratory (NREL), the Research Support Facility (RSF). Daylighting had to be integrated with the electric lighting, as low energy use (50% below ASHRAE 90.1-2004) and the LEED daylight credit were contractually required, with a reach goal of being a net-zero energy building (NZEB). The oft-ignored disconnect between lighting simulation and whole-building energy use simulation had to be addressed, as ultimately all simulation efforts had to translate to energy use intensity predictions, design responses, and preconstruction substantiation of the design. We present preliminary data from the postoccupancy monitoring efforts with an eye toward the current efficacy of energy and lighting simulation methodologies.
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.
