This case study describes the National Renewable Energy Laboratory's (NREL) data center as a showcase of energy efficiency. Most of what NREL has done can be replicated by clients; however, two design approaches are climate-dependent: near-full reliance on outside air for cooling, and photovoltaic arrays for power.

The Research Support Facility is designed to be one of the world's largest net-zero energy buildings. It incorporates new technologies and techniques and draws on centuries-old concepts. Its operable windows allow natural ventilation. It monitors indoor and outdoor temperatures and displays messages on each computer about opening or closing windows.
This presentation discusses the importance of selecting a project delivery method that balances performance, best value, and cost savings.
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.
This report presents a set of 15 best practices for owners, designers, and construction teams to reach high-performance goals and maintain a competitive budget. These best practices are based on the recent experiences of the Research Support Facility owner and design-build team for the Research Support Facility (RSF) on the National Renewable Energy Laboratory’s (NREL) campus in Golden, Colorado, and show that achieving this high performance outcomes requires that all key integrated team members understand their opportunities to control capital costs.

This presentation decribes how building an energy-efficient data center can improve a business's bottom line.
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.

It is still early in the collection and analysis of energy performance data, but it is already clear that high-performance commercial buildings—some "almost net-zero buildings"—can be constructed cost effectively, providing productive environments for occupants, reducing operating costs, and enhancing the competitiveness of commercial properties.
