The Advanced Energy Retrofit Guide for K-12 Schools is one of five retrofit guides commissioned by the U.S. Department of Energy. By presenting general project planning guidance as well as more detailed descriptions and financial payback metrics for the most important and relevant energy efficiency measures, the guides provide a practical roadmap for effectively planning and implementing performance improvements in existing buildings. The K-12 Schools guide provides convenient and practical guidance for making cost-effective energy efficiency improvements in public, private, and parochial schools.
Article in the Whole Building Design Guide about the uses and features of metal roofs that meet "cool roof" standards.
Presentation slides from Human Factors and Post‐Occupancy Evaluation presentation given at the NASA Net-Zero Energy workshop June 5-6, 2012.
This paper describes the development of energy efficiency recommendations for achieving 30% whole-building energy savings in K-12 schools over levels achieved by following the ANSI/ASHRAE/IESNA Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings (over both the 1999 and 2004 versions of the standard).

This paper reviews the novel procurement, acquisition, and contract process of a large-scale replicable net zero energy (ZEB) office building. The owners (who are also commercial building energy efficiency researchers) developed and implemented an energy performance based design-build process to procure an office building with contractual requirements to meet demand side energy and LEED goals. The key procurement steps needed to ensure achievement of the energy efficiency and ZEB goals using a replicable delivery process are outlined.
This paper documents the methodology developed to identify and reduce plug and process loads (PPLs) as part of NREL's Research Support Facility's (RSF) low energy design process. PPLs, including elevators, kitchen equipment in breakrooms, and office equipment in NREL’s previously occupied office spaces were examined to determine a baseline. This, along with research into the most energy-efficient products and practices, enabled the formulation of a reduction strategy that should yield a 47% reduction in PPLs. The building owner and the design team played equally important roles in developing and implementing opportunities to reduce PPLs. Based on the work done in the RSF, a generalized multistep process has been developed for application to other buildings.
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.
