An energy-efficient data center includes targets for its power usage effectiveness (<1.2) and energy resource efficiency (< 0.9). It should be designed with hot isle–cold isle separation, use free cooling (economizer) and evaporative cooling when available, minimize fan energy, and use the most energy-efficient equipment possible.

This fact sheet summarizes recommendations for designing new office buildings that result in 50% less energy use than conventional designs meeting minimum code requirements. The recommendations are drawn from the Advanced Energy Design Guide for Small to Medium Office Buildings, an ASHRAE publication that provides comprehensive recommendations for designing low-energy-use office buildings with gross floor areas up to 100,000 ft2.
Designed as a stand-alone document, this fact sheet provides key principles and a set of prescriptive design recommendations appropriate for smaller
office buildings with insufficient budgets to fully implement best practices for integrated design and optimized performance. The recommendations have undergone a thorough analysis and review process through ASHRAE, and have been deemed an easily replicable combination of measures to achieve 50% savings in the greatest number of office buildings.
How to determine the amount of continuous insulation required by codes, while still retarding water vapor according to climate zone locations
"While ASHRAE 90.1 has been pushing continuous insulation (CI) for the past decade, the building codes are catching on. And now that the U.S. Department of Energy (DoE) has mandated all states to adopt a commercial building energy code that meets or exceeds ASHRAE Standard 90.1-2010, CI specifications are really being cast into the spotlight."
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 U.S. Department of Energy’s National Renewable Energy Laboratory is devising a new design-build project delivery model for fast-tracked, net-zero energy building. The process is progressive, performance-based design-build.
A detailed two page case study on the Zero Energy Ready Turkey Foot Middle School.
"Turkey Foot is revolutionizing the way kids learn, all within a new building that uses half the energy of the previous school despite being twice the size. Turkey Foot leveraged the practices and experience on other high performance goals in the District."
Encouraging commercial building owners to set measurable energy goals before design begins can drive design and contractor teams to develop innovative energy efficiency solutions within conventional building budgets. The successes and lessons learned by a federal building owner's performance-based procurement project formed the basis of an expanded program using utilities as the outreach channel to replicate the approach. The utilities delivered incentive-based offerings to focus building owners on the whole building rather than on individual building components and systems. This 11-page paper documents the core principles, successes and lessons learned from these utility programs in different areas of the country.
The National Institute of Building Sciences (NIBS)–under contract from the Army Corps of Engineers, the Naval Facilities Engineering Command, the US Air Force, the General Services Administration, the Department of Energy, and the Federal Emergency Management Agency—has developed this comprehensive federal guide for exterior envelope design and construction for institutional/office buildings.
This case study highlights the design, implementation strategies, and continuous performance monitoring of NREL's Research Support Facility data center.
