Design Team Commitment: Contractor Perspective on Cost Control presentation given at the NASA Net-Zero Energy workshop June 5-6, 2012
NREL experienced a significant increase in employees and facilities on our 327-acre main campus in Golden, Colorado over the past five years. To support this growth, researchers developed and demonstrated a new building acquisition method that successfully integrates energy efficiency requirements into the design-build requests for proposals and contracts. We piloted this energy performance based design-build process with our first new construction project in 2008. We have since replicated and evolved the process for large office buildings, a smart grid research laboratory, a supercomputer, a parking structure, and a cafeteria. Each project incorporated aggressive efficiency strategies using contractual energy use requirements in the design-build contracts, all on typical construction budgets. We have found that when energy efficiency is a core project requirement as defined at the beginning of a project, innovative design-build teams can integrate the most cost effective and high performance efficiency strategies on typical construction budgets. When the design-build contract includes measurable energy requirements and is set up to incentivize design-build teams to focus on achieving high performance in actual operations, owners can now expect their facilities to perform. As NREL completed the new construction in 2013, we have documented our best practices in training materials and a how-to guide so that other owners and owner’s representatives can replicate our successes and learn from our experiences in attaining market viable, world-class energy performance in the built environment.

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 describes how net-zero energy buildings will produce, during a typical year, enough renewable energy to offset the energy they consume from the grid.
This conference paper discusses four well-documented definitions of net-zero energy: net-zero site energy, net-zero source energy, net-zero energy costs, and net-zero energy emissions, along with pluses and minuses of each.
This paper introduces a classification system for net-zero energy buildings (ZEB) based on the renewable sources a building uses.
First costs, or capital costs, for energy efficiency strategies in office buildings are often a primary barrier to realizing high-performance buildings with 50% or greater energy savings. Historically, the industry has been unable to reach deep energy savings because of a reliance on energy cost savings and simple payback analysis alone to justify investments. A more comprehensive and integrated cost justification and capital cost control approach is needed. By implementing innovative procurement and delivery strategies, integrated design principles and cost tradeoffs, life cycle cost justifications, and streamlined construction methods, first cost barriers can be overcome. It is now possible to attain marketable, high-performance office buildings that achieve LEED Platinum and reach net zero energy goals at competitive whole building first costs, as illustrated by the U.S. Department of Energy’s and National Renewable Energy Laboratory’s latest high-performance office building, the Research Support Facility (RSF) on the National Renewable Energy Laboratory campus in Golden, Colorado.
