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 guide presents a set of 15 best practices for owners, designers, and construction teams to reach high-performance goals and maintain a competitive budget. They are based on the recent experiences of the Research Support Facility owner and design-build team, and show that achieving this outcome requires that all key integrated team members understand their opportunities to control capital costs.
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.
The purpose of this handbook is to furnish guidance for planning and conducting a highperformance building charrette, sometimes called a "greening charrette." The handbook answers typical questions such as, "What is a charrette?", "Why conduct a charrette?", "What topics should we cover?", "Whom should we invite?" and "What happens after the charrette?". Owners, design team leaders, site planners, state energy office staff, and others who believe a charrette will benefit their projects will find the handbook helpful.
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.
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.
