On the Ignition of Fuel Beds by Firebrands.

May 11, 2005
Author(s)
Samuel L. Manzello, Thomas G. Cleary, John R. Shields, Jiann C. Yang
An experimental apparatus has been built to investigate the ignition of fuel beds as a result of impact with burning firebrands. The apparatus allowed for the ignition and deposition of both single and multiple firebrands onto the target fuel bed. The

A Curve-Based Mixed System Rating Method for Unitary Air Conditioners

May 2, 2005
Author(s)
William V. Payne, Piotr A. Domanski
The curve-based method was evaluated based on performance predictions for nine mixed systems, which were also tested by an independent testing laboratory. Capacity predictions were within 5% of the tested values for six of nine mixed systems, and four of

Ventilation Design and Performance in U.S. Office Buildings

April 30, 2005
Author(s)
Andrew K. Persily, J Gorfain
Building ventilation is a primary determinant of indoor air quality (IAQ) as it impacts contaminant concentrations and occupant comfort in terms of the perception of odor and irritation. However, relatively few measurements of office building ventilation

Flammability of Polymer Clay Nanocomposites Consortium:Final Report

April 4, 2005
Author(s)
Jeffrey W. Gilman, Takashi Kashiwagi, A B. Morgan, Rick D. Davis, Richard H. Harris Jr., L D. Brassell
In 1997 NIST reported that polymer layered-silicate (clay) nanocomposites exhibit reduced flammability, in the form of reduced heat release rate (HRR). The unique character of this new approach to flame retard polymeric materials was the dual benefit of

Developing a More Rapid Test to Assess Sulfate Resistance of Hydraulic Cements

March 16, 2005
Author(s)
Chiara F. Ferraris, Paul E. Stutzman, Max A. Peltz, John A. Winpigler
External sulfate attack of concrete is a major problem that can appear in regions where concrete is exposed to soil or water containing sulfates, leading to softening and cracking of the concrete. Therefore, it is important that materials selection and

Building Orientation and Wind Effects Estimation

March 1, 2005
Author(s)
P Hanzlik, S M. Diniz, A Grazini, Mircea Grigoriu, Emil Simiu
The methodology for estimating wind effects presented in this paper is based on the database-assisted design approach. It accounts for the effects of wind directionality, for the effects of the uncertainties in the parameters that determine wind effects
