"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."

In the cold climate of the upper Midwest, air-source VRF systems have difficulty meeting heating loads when the outdoor temperatures drop below -5ºF. Because of this difficulty during common cold spells, they are either oversized (adding to system cost) or supplemental heat is added (adding to operating cost). Cold temperatures can also cause frost issues around outdoor units, as well as compressor failure. A VRF system served by a water loop—in place of air—does not have these issues, making the technology more practical and effective in cold climates such as the upper Midwest. A water-source VRF system can be connected to a boiler and cooling tower or, for even higher performance, a ground heat exchanger.
This document provides an example request for proposal (RFP) created by the U.S. Army Corps of Engineers, Omaha District in June 2012 for Fort Carson Net Zero Army Barracks. The RFP has been annotated by the National Renewable Energy Lab (NREL) to demonstrate the project’s steps that follow NREL and DOE’s Energy-Performance-Based Acquisition process.
This presentation Session II from the RSF Workshop discusses the performance-based design-build process, which was used to procure and construct the Research Support Facility.
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.
Presentation by NREL researcher Shanti Pless about Controlling Capital Costs in High-Performance Buildings Using a Performance Based Design-Build Process
Acquisition Process for the Design-Build of the Research Support Facility presentation given at the NASA Net-Zero Energy workshop June 5-6, 2012
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.
