Author(s)
Richard Lau, Sami Ayyorgun, Siun Chuon Mau, Archan Misra, David Holmberg, Steven T. Bushby
While it is well recognized that renewable microgrid generation and intelligent storage can significantly reduce a building's need for grid power and its peak loading, there is currently no sound and generalized approach to combine these two technologies

Measurement Science Roadmap for Net-Zero Energy Buildings

March 18, 2010
Author(s)
Joan Pellegrino, Arthur H. Fanney, Andrew K. Persily, Piotr A. Domanski, William M. Healy, Steven T. Bushby
Buildings account for nearly a third of the world s energy use today, and this share is expected to rise along with population growth and levels of prosperity. In the United States, residential and commercial buildings consume about 40% of primary energy

Ontology Development For Low-Energy Building Embedded Commissioning

November 17, 2009
Author(s)
Kwang Jun Lee, Omer Akin, Burcu Akinci, James Garrett, Steven T. Bushby
This paper presents the results of initial work in developing an ontology for improving information exchange and automation in building system commissioning practices. In our previous research dealing with the derivation of product models from building

BACnet and the Smart Grid

November 1, 2009
Author(s)
David G. Holmberg, Steven T. Bushby
The future Smart Grid will be a transformation of the current electric grid. The key enablers for this transformation will be dynamic rates and the ability for customers and the utility to communicate and respond in real time. This in turn will produce an

The Virtual Cybernetic Building Testbed-A Building Emulator

July 16, 2009
Author(s)
Steven T. Bushby, Michael A. Galler, Natascha S. Milesi-Ferretti, Cheol D. Park
Building emulators couple computer simulations to real control hardware, creating a useful tool for studying building control system performance. The National Institute of Standards and Technology's Virtual Cybernetic Building Testbed (VCBT) is a whole

Advancing Automated Demand Response Technology

January 28, 2009
Author(s)
Steven T. Bushby, David G. Holmberg
For several years electric utilities have implemented a wide variety of programs to curtail load in times of stress on the electricity distribution grid or on generating capacity. Although these programs have shared a common goal of reducing peak

Building Networks and Public Safety Communications

November 18, 2008
Author(s)
David G. Holmberg, Stephen J. Treado, William D. Davis, Steven T. Bushby, Alan B. Vinh, Michael A. Galler, R Vettori
The Building Networks and Public Safety Communications project has three components: (1) addressing feasibility of using building networks for bridging first responder radio communications into buildings, (2) recommending changes to the SAFECOM Statement
