BEES 2.0: Building for Environmental and Economic Sustainability Peer Review Report

April 1, 2002
Author(s)
M A. Curran, J G. Overly, P Hofstetter, R Muller, Barbara C. Lippiatt
This report documents the results of a technical review of the BEES (Building for Environmental and Economic Sustainability) 2.0b software and user manual. BEES measures the life-cycle environmental and economic performance of building products using

Refrigerant Flow Through Flexible Short-Tube Orifices

April 1, 2002
Author(s)
William V. Payne, Y C. Kim, Dennis L. O'Neal, Mohsen Farzad
Flexible short-tube orifices were designed to decrease their diameter as the pressure differential across them increases under high outdoor temperatures. A series of tests for an R-22/lubricant mixture (mass fraction of oil 1.2%) were performed with two

Refrigerant Flow Through Flexible Short-Tube Orifices

April 1, 2002
Author(s)
Y Kim, D L. O'Neal, William V. Payne, MD L. Farzad
A series of tests for a R-22/lubricant mixture (1.2 % oil concentration) were performed with two flexible short tube orifices to develop flow data over a range of typical air conditioner operating conditions. One orifice had a modulus of elasticity of 7063

Stoichiometry of Slag Hydration With Calcium Hydroxide

April 1, 2002
Author(s)
J M. Richardson, Joseph J. Biernacki, Paul E. Stutzman, Dale P. Bentz
The stoichiometry of the reaction between ground granulated blast furnace slag (GGBFS) having an empirical formula of C 7.d88^ S 7.39 and calcium hydroxide (CH) was investigated. Scanning electron microscopy (SEM) was used to determine the slag consumption

Evaluation of the Computer Fire Model DETACT-QS

March 20, 2002
Author(s)
Morgan J. Hurley, Daniel M. Madrzykowski
The proper use of engineering design methods requires an understanding of their applicability and limitations, since all design methods are, at least to a certain extent, empirically based. Equations or constants used within design methods are frequently

New Tools for Specifying BACnet

March 1, 2002
Author(s)
Steven T. Bushby
The BACnet communication protocol standard makes it possible to integrate a wide variety of building automation and controlproducts. Building owners and the consulting engineering community have had difficulty understanding how to write quality

Particle Formation in Laminar Flames Inhibited by Metals

March 1, 2002
Author(s)
Gregory T. Linteris, M D. Rumminger
Some organometallic compounds of iron are two orders of magnitude more effective at volume fraction than CF 3Br in premixed flames, an order of magnitude more effective in counterflow diffusion flames. The condensation of active gas-phase iron-containing

Promoting Quality in Laboratory Testing

March 1, 2002
Author(s)
J H. Pielert
The Cement and Concrete Reference Laboratory (CCRL) provides laboratory inspection and proficiency sample programs that are used to evaluate testing laboratory competency. CCRL, which is sponsored by ASTM, along with the American Association of State

Quantum Efficiency of Spectral UV on Polyurethanes

March 1, 2002
Author(s)
Tinh Nguyen, Jonathan W. Martin, E Byrd, E Embree
Polyurethanes (PU) are used extensively as exterior building materials. However, PU undergoes degration during outdoor exposure. The quantum efficiency of spectral UV on photodegration of an acrylic-urethane coating has been investigated. Samples of

The Visible Cement Data Set

March 1, 2002
Author(s)
Dale P. Bentz, S Mizell, Steven G. Satterfield, J E. Devaney, William L. George, Peter M. Ketcham, James R. Graham, J E. Porterfield, Daniel A. Quenard, F A. Vallee, H Sallee, E Boller, J Baruchel
With advances in X-ray microtomography, it is now possible to obtain three-dimensional representations of a material's microstructure with a voxel size of less then one micrometer. The Visible Cement Data Set represents a collection of 3-D data sets

Determination of Planck Mean Absorption Coefficients for HBr, HCl, and HF

February 1, 2002
Author(s)
Stephen P. Fuss, Anthony P. Hamins
The Planck mean absorption coefficient has been calculated for HBr HCl, and HF over a temperature range from 300 K-2300 K using data from the 1996 edition of the HITRAN molecular database. Plots of ap versus temperature showed monotonically decreasing

Development of a Reliability-Based Method of Service Life Prediction for Sealant

February 1, 2002
Author(s)
Christopher C. White, C Buch, Mark R. VanLandingham
Standard test methods, such as ASTM C719, evaluate sealant performance though threshold test measurements. This method and its derivatives do not offer reliable predictions of in-service performance. This article will detail efforts to move away from the
