Interoperable Methodologies and Techniques in CAD

December 1, 2009
Author(s)
Semiha Kiziltas, Fernanda Leite, Burcu Akinci, Robert R. Lipman
It is estimated that the cost of inadequate interoperability in the U.S. capital facilities industry is approximately $15.8 billion per year. Lack of or inadequate interoperability results in data and transfer problems and duplication of business

Rethinking Egress: A Vision for the Future

November 30, 2009
Author(s)
Jason D. Averill, Richard D. Peacock
New technologies and research are redefining the state-of-the-art in building evacuation. The time is right to rethink the entire infrastructure of egress from buildings in light new opportunities to address the economic and life-safety issues

Effect of Air Infiltration and Ventilation

November 17, 2009
Author(s)
Andrew K. Persily, Steven J. Emmerich
This chapter discusses the role of air infiltration and ventilation in building moisture transport. While water vapor diffusion can be a very important moisture transport mechanism, as discussed in other chapters, bulk air movement via infiltration and

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

Sundararajan, Elena Timofeeva, Todd Tritcak, A.N. Turanov, Stefan Van Vaerenbergh, Dongsheng Wen, Sanjeeva Witharana, Charles Chun Yang, W.-H. Yeh, Xiao-Zheng Zhao, Sheng-Qi Zhou
This article reports on the International Nanofluid Property Benchmark Exercise (INPBE) in which the thermal conductivity of identical samples of colloidal dispersions of nanoparticles, or nanofluids , was measured by over 30 organizations worldwide, using

Go with the Flow. Nist Study Proves PPV can Save Lives & Improve Safety

November 1, 2009
Author(s)
Stephen Kerber, Daniel M. Madrzykowski
The Building and Fire Research Laboratory at the National Institute of Standards and Technology (NIST) started a Fire Fighting Technology Group in order to focus on the research needs of the fire service. One key objective of the group is to provide

Fitting Spheres to Range Data from 3D Imaging Systems

October 1, 2009
Author(s)
Marek Franaszek, Geraldine S. Cheok, Kamel S. Saidi, Christoph J. Witzgall
Two error functions used for nonlinear Least Squares (LS) fitting of spheres to range data from 3D imaging systems are discussed: orthogonal error function and directional error function. Both of the functions allow unrestricted gradient-based minimization

Gauging the Repeatability of 3D Imaging Systems by Sphere Fitting

September 30, 2009
Author(s)
Marek Franaszek, Geraldine S. Cheok, Kamel S. Saidi
Multiple scans of the same object acquired with 3D imaging system (e.g., laser scanner) in the same experimental conditions could provide valuable information about the instrument s performance (e.g., stability, existence of bias, measurement error)

Guidelines for Accepting 2D Building Plans (NIST IR 7638)

September 30, 2009
Author(s)
Geraldine S. Cheok, James J. Filliben, Alan M. Lytle
The General Services Administration's (GSA) Public Buildings Services manages 1600 buildings totaling 180, 000, 000 square feet. GSA’s ability to capture, validate, and report the spatial information of its building assets (e.g., dimensions, areas, and

Building Plumbing System Decontamination - First Report on Recommendations

September 6, 2009
Author(s)
Stephen J. Treado, Mark A. Kedzierski, Stephanie S. Watson, Nicos Martys, Kenneth D. Cole
This report summarizes the measurement results and recommended procedures for responding to building plumbing system contamination incidents and restoring the water system to safe operation. The recommendations are based on analysis of the results of a

Assessing the Measurement Uncertainty of Thermophysical Properties

September 2, 2009
Author(s)
Robert R. Zarr
A generalized approach for the expression of measurement uncertainty consistent with current international practice is presented. The approach is applicable to all kinds of quantitative measurements including measurements of thermophysical properties. A
