This paper observes that a key problem with current energy code practice is the difficulty in determining what level of performance the codes are delivering. Current energy code practice is based on estimated energy use of a theoretical sample of buildings that meet all code requirements.
It goes on to suggest that a possible solution to many of these problems is to calibrate energy codes to actual building performance. By determining how buildings that are built to code are really performing, a wide range of new opportunities for code improvement becomes available.

This paper describes target setting, modeling, and performance validation approaches adopted from the outset by the new University of California, Merced campus, including detailed results for one building. Successes and lessons learned in implementing this process can support other building projects on the trajectory toward zero net energy, as well as provide insights for
program design, implementation, and evaluation.
Presented at the 2010 ACEEE Summer Study on Energy Efficiency in Buildings.
The Classroom and Office Building (COB) examined in this case study is one of five buildings in the initial phase of development at UC Merced. This case study examines the actual post-occupancy performance of COB in relation to design elements and objectives. The measurements cover July 2007 through June 2008.
Science & Engineering (S&E) Building I is one of five buildings in the initial phase of development at UC Merced. This case study examines the actual post-occupancy energy performance of S&E in relation to design elements and objectives.
A synopsis of the comprehensive and integrated revisions to the International Energy Conservation Code (IECC) submitted by NBI, the American Institute of Architects (AIA) and the U.S. Department of Energy (DOE).
The year-long study, "Energy Performance of LEED for New Construction Buildings," suggests significant opportunities for program improvement, even while it is clear that LEED is having a positive impact on building energy performance. As this information has been made publicly available, several common questions have been asked about how LEED data was summarized in the report. While many of the answers to these questions are addressed in the report itself, we have developed a factsheet of Frequently Asked Questions to facilitate access to the answers.
Green building program energy efficiency strategies often use integrated design, precluding the measurement of results simply from deemed savings of specific measures. This paper describes the use of whole-building measured energy use, by month and fuel, to evaluate the achievements of high performance building programs at both the individual building and program level.
Under a project for the U.S. Environmental Protection Agency, NBI researched trends and new technologies in advanced metering as used in energy information systems (EIS).
This research is part of an effort to develop a reliable commercial rooftop unitary (RTU) field service/repair (also known as “retrocommissioning”) protocol, along with a higher level of confidence in the associated energy savings necessary to justify RTU service programs. This report documents the results of the Phase 2 project.
This white paper, also known as "My Car Is Smarter Than Your Building," looks at the lessons controls-savvy cars can teach us about how high performance and enlightened controls standards can lead to more energy efficient buildings.
