IFC File Analyzer Software

March 30, 2017
Author(s)
Robert R. Lipman
The IFC File Analyzer software generates a spreadsheet or CSV files from an IFC file. IFC (Industry Foundation Classes) is the data exchange standard used to facilitate interoperability in the building and construction industry. IFC is developed by

CYCLE_D: NIST Vapor Compression Cycle Design Program, Version 5.1.1; Users Guide

March 9, 2017
Author(s)
Piotr A. Domanski, J S. Brown, Eric W. Lemmon
The CYCLE_D package simulates vapor compression refrigeration cycles that use pure refrigerants or blends of refrigerants. The model can simulate a basic subcritical or transcritical refrigeration cycle, both with or without a liquid-line/suction-line heat

IAQ Assessments in High Performing Building

March 5, 2017
Author(s)
Kevin Teichman, Steven Emmerich, Andrew K. Persily
Despite numerous efforts to encourage good indoor air quality (IAQ) in high-performing buildings, including several building rating programs, measured IAQ performance data in high- performing buildings are limited. This presentation summarizes data that

A Boolean Approach to Modeling Logical Constraints

February 19, 2017
Author(s)
L I. Schultz
This paper presents a method that uses Boolean logic to model complex logical constraints in a zero-one integer programming optimization. The article examines how the problem of inding a least-cost plan of compliance with building fire codes can be modeled

A Comparison of Quality of Dispersion of Single Wall Carbon Nanotubes Using Different Surfactants and Biomolecules

February 19, 2017
Author(s)
Jeffrey W. Gilman, R Haggenmueller, Sameer Rahatekar, Jeffrey Fagan, Jae H. Chun, Matthew Becker, Rajesh R. Naik, Todd Krauss, Lisa Carlson, Shana O. Kelley, Paul C. Trulove, D M. Fox, John Kadla
The application of single wall carbon nanotubes (SWCNT) in current and future applications crucially depends on the ability to process SWCNT in a solvent to yield high quality dispersions characterized by individual SWCNTs and possessing a minimum of SWCNT

A Direct Error Measure for Affine Models of Nonlinear Algebraic Systems

February 19, 2017
Author(s)
D M. Lorenzetti
This paper proposes a measure of the deviation between a nonlinear equation and its affine model, and demonstrates applications to nonlinear systems. The measure expresses the model error relative to a representative change in its predicted value

A Performance-Based Analysis of a Hotel Building Using Two Egress Models

February 19, 2017
Author(s)
Erica D. Kuligowski, James A. Milke
This report compares results from similar egress models based on documented evacuation movement data. When EXIT89 and Simulex1 are used to 1) simulate the same design scenarios and 2) perform a bounding analysis of the hotel building, differences in egress
