Owned by the U.S. Department of Energy (DOE), the RSF incorporates several innovative design features and renewable energy strategies developed at the National Renewable Energy Laboratory (NREL). The 222,000 sq. ft., LEED™ platinum office building is occupied by about 800 NREL and DOE employees.
The energy goal for the building is 32kBtu/ft2/year. A rooftop photovoltaic system is to be implemented through a Power Purchase Agreement; daylighting; natural ventilation; and a next-generation, energy efficient data center are just a few of the energy features of the building.
| Much of the south-facing wall at the RSF employs passive heating technology developed at NREL. Highly efficient, these collectors can capture up to 80 percent of the energy of the sunlight striking the collector. Outside ventilation air is passively preheated via transpired solar collectors (a technology developed by NREL) on the RSF building’s south face. By using a dark-colored, perforated metal plate on the south side of a building, three NREL scientists have perfected a way for buildings to pre-heat the air coming in, reducing the need for additional heating energy. The basic concept of a transpired solar air collector is for the perforated plate to be warmed by the sunlight hitting the south side of a building. A fan added to the building’s existing ventilation system slowly draws warmed ventilation air into the building through the plate. The solar energy absorbed by the dark plate is transferred to the air flowing through it. This process can efficiently preheat the air going into a building like the RSF by as much as 40 degrees F.

A new fact sheet, Research Support Facility—A Model of Super Efficiency (PDF 461 KB), provides more information about the design-build approach, high-performance design features, materials, the workplace of the future, and a cost comparison summary.
The RSF design and construction experience is being chronicled and will be shared widely to promote the production of high-performance building designs at competitive costs.

Building Description
The RSF building was designed for about 800 staff from NREL and the Department of Energy. This new flagship building:
- Incorporates the concepts of safe design into the planning, design, construction, and operation of the facility
- Meets the Platinum certification as defined by the US Green Buildings Council Leadership in Energy and Environmental Design (LEED™) Green Building Rating System
- Meets the requirements of the workforce of today and tomorrow
- Provides the lowest attainable energy use per square foot
- Provides an architectural image that is consistent with the site and NREL’s identity.

Getting to Net Zero Energy Through a Performance-Based Design/Build Process
Jeff Baker from the U.S. Department of Energy (DOE), Phil Macey from Haselden Construction, and Bill Glover from NREL discuss how the RSF and net-zero energy buildings are achievable and marketable now in this DOE Building Technologies Program Webinar.

Design-Build Contract
A design-build contract of approximately $64 million was awarded for the RSF, and the design-build team includes Haselden Construction and RNL. The benefits of the design-build process are:
- One contractor performs architecture/engineering and construction to improve project efficiency, cost, scope, and schedule performance
- The competitive market provides the most technically-sound and cost-effective solution based on well-defined user performance standards
- Project delivery and execution improves.
RSF Prototype at Golden Hill
NREL’s Information Services (IS) staff prototyped the new workstations and technologies planned for the RSF. This helped ensure that employees moving into the RSF would know all about the “workplace of the future.”
Nearly 100 employees prototyped several new workstation configurations that utilized shorter cube heights and allowed for maximum daylighting and lower energy costs. Along with the furniture, IS tested many of the new information technologies now in the RSF. Learn how NREL tested the energy-saving office of the future.
