What Are Lighting Controls Protocols, and Why Does Anyone Care About Them?

July 31, 2003
Author(s)
Stephen J. Treado
Lighting controls protocols are discussed. Key elements are power and flexibility, both in system design and implementation, and in operation. The overriding tred is towards ever-increasing user expectations, needs, and requirements, along with equipment

A Hurricane Damage Prediction Model for Residential Structures

July 1, 2003
Author(s)
A Cope, K Gurley, James J. Filliben, Emil Simiu, J P. Pinelli, C Subramanian, L. Zhang, S Hamid
The focus of this paper is the development of a probabilistic model for the prediction of structural damage due to hurricane winds in the state of Florida. This is a necessary component to a model currently under development to predict annualized insurable

BACnet Wide Area Network Security Threat Assessment

July 1, 2003
Author(s)
David G. Holmberg
This technical report addresses inter-networked building automation and control systems (BAS or BCS) using the BACnet protocol [ANSI/ASHRAE, 2001]. The report deals with threats from known sources due to communication connections to the corporate LAN and

Bench-Scale Flammability Measures for Electronic Equipment

July 1, 2003
Author(s)
Matthew F. Bundy, Thomas J. Ohlemiller
An experimental study of the bench-scale fire performance of 18 commercial polymeric materials was conducted by the National Institute of Standards and Technology. The performance of these materials was characterized using three standard flammability tests

Integration of Airflow and Energy Simulation Using CONTAM and TRNSYS

July 1, 2003
Author(s)
Timothy P. McDowell, Steven Emmerich, J B. Thornton, George Walton
The impact of infiltration and ventilation flows on the energy use in commercial buildings has received little attention. One of the reasons for this lack of study is that the commonly-used programs for estimating the energy use of buildings do not

Measurement of the Optical Extinction Coefficients of Post-Flame Soot in the Infrared

July 1, 2003
Author(s)
J F. Widmann, Jiann C. Yang, Samuel L. Manzello, George W. Mulholland
The optical extinction coefficients of post-flame soot have been measured in the wavelength range 2.8 micrometers to 4.1 micrometers. A laminar diffusion burner was combined with an infrared spectrograph and gravimetric measurements to determine the mass

Report of Experimental Results for Tests 2,3, and 4 of the International Fire Model Benchmarking and Validation Exercise #3

July 1, 2003
Author(s)
Anthony P. Hamins, Michelle K. Donnelly, Erik L. Johnsson, Alexander Maranghides, George W. Mulholland
As part of its Fire Risk Research Program, the NRC (Nuclear Regulatory Commission) and NIST (National Institute of Standards and Technology) are participating in an International Collaborative Fire Model Project (ICFMP) to assess and validate fire computer

Durability Gap Analysis for Fiber-Reinforced Polymer Composites in Civil Infrastructure

June 18, 2003
Author(s)
V M. Karbhari, Donald L. Hunston, B Benmokrane, T Juska, Roy S. Morgan, J Lesko, U Sorathia, D R. Reynaud
The lack of a comprehensive, validated, and easily accessible data base for the durability of fiber-reinforced polymer _FRP_composites as related to civil infrastructure applications has been identified as a critical barrier to widespread acceptance of

Light Scattering Characteristics and Size Distribution of Smoke and Nuisance Aerosols

June 16, 2003
Author(s)
D W. Weinert, Thomas Cleary, George W. Mulholland, P F. Beever
This paper presents the differential mass scattering cross section [m 2multiply by}g -1multiply by}sr -1] of various non-flaming and flaming fire generated smoke aerosols as well as nuisance aerosols created in the Fire Emulator/Detector Evaluator. These

Measurement of Soot Extinction Coefficients

June 16, 2003
Author(s)
J F. Widmann, Jiann C. Yang, George W. Mulholland, Anthony P. Hamins
An experimental apparatus used to obtain soot extinction coefficients in the infrared portion of the electromagnetic spectrum will be presented. Numerous experimental measurements of soot extinction coefficients have been previously obtained at visible

A Model to Predict Hurricanes Induced Losses for Residential Structures

June 1, 2003
Author(s)
J P. Pinelli, C Subramanian, L. Zhang, K Gurley, A Cope, Emil Simiu, S M. Diniz, S Hamid
This paper presents a practical probabilistic model for the projection of annualized damage costs to residential structures due to hurricanes. The estimation of the damage is accomplished by first defining the basic damage modes for components of specific

BFRL Publications, 2002

Welcome to BFRL Publications, 2002. These two CD-ROMs contain publications produced by BFRL staff, publications resulting from contracts or grants with BFRL and publications contained in poceedings from BFRL sponsored conferences orworkshops. The Volume 1

Cold Discharge of CF 3 I in a Simulated Aircraft Engine Nacelle

June 1, 2003
Author(s)
Jiann C. Yang, Samuel L. Manzello, Marc R. Nyden, M D. Connaghan
An aircraft engine nacelle simulator was built to study the dispersion behavior of CF3I, a potential halon 1301 (CF3Br) replacement, at an extremely cold temperature (nominally 40 C). The experimental fixture consists of a simulated engine nacelle with
