White Paper on Fire Resistance of Concrete Structures

September 18, 2014
Author(s)
Luke Bisby, Hossein Mostafaei, Pierre Pimienta
This white paper presents the current, international, state-of-the-art large-scale experimental, modeling, and performance-based design (PBD) efforts related to structural fire resistance of concrete structures. The paper addresses these topics with

White Paper on Fire Resistance of Timber Structures

September 18, 2014
Author(s)
Andrew Buchanan, Birgit SP Wood Technology, Sweden tman, Andrea Frangi
Fire resistance of timber structures is a very large field. In order to keep this document relatively small, the scope of is limited as follows: • This report attempts to define a Performance-Based framework for the fire safety design of multi-story timber

Effect of Ozonation on Fungal Resistance of Bamboo and Oak

August 15, 2014
Author(s)
Chi Hoang, Tinh Nguyen, Deborah Jacobs, Andrew K. Persily, Richard Cosi
Wood is gaining increased interest as a renewable building material. However, color changes, chemical and microbiological degradation can occur when lignocellulosic materials are exposed to environmental stressors such as ozone and elevated humidity. In

Infiltration in energy modeling: a simple equation made better

August 8, 2014
Author(s)
Lisa C. Ng, Andrew K. Persily, Steven J. Emmerich
As building envelope performance and HVAC equipment efficiencies continue to be improved to reduce building energy use, a greater percentage of the total energy loss of a building can occur through envelope leakage. Although the energy impacts of

Long Term Air Quality Monitoring in a Net-Zero Energy Residential Test Facility Designed with Specifications for Low Emitting Interior Products

August 6, 2014
Author(s)
Dustin G. Poppendieck, Lisa C. Ng, Matthew P. Schlegel, Andrew K. Persily, Alfred Hodgson
This study evaluated the effectiveness of a low-VOC (volatile organic compounds) specification designed to minimize occupant exposures to indoor air pollutants in a net-zero energy research house meeting the ASHRAE Standard 62.2 ventilation requirements

Long Term Emissions from Spray Polyurethane Foam Insulation

August 6, 2014
Author(s)
Dustin G. Poppendieck, Steven J. Nabinger, Matthew P. Schlegel, Andrew K. Persily
The desire to build more energy efficient homes in the United States has lead to the expansion of the residential spray polyurethane foam (SPF) insulation industry. Annually, over 100,000 homes in the United States are constructed or retrofit using SPF

Simulation Study of Carbon Monoxide Exposure from Portable Generators in U.S. Residences

August 6, 2014
Author(s)
Andrew K. Persily, Steven J. Emmerich, Yanling Wang, Brian J. Polidoro
A simulation study was conducted to evaluate indoor CO exposures as a function of portable generator location and CO emission rate in order to support the development of potential CO emission limits for generators. These simulations employed the multizone

Smart Firefighting Workshop Summary Report

August 6, 2014
Author(s)
Anthony P. Hamins, Nelson P. Bryner, Albert W. Jones, Galen H. Koepke, casey grant, Anand Raghunathan
This report summarizes the results of the Smart Firefighting Workshop held March 24 and 25, 2014, in Arlington, Virginia and sponsored by the National Institute of Standards and Technology (NIST). The Workshop provided a forum to help identify and

Ignition of Mulch Beds Exposed to Continuous-Wind Driven Firebrand Showers

August 3, 2014
Author(s)
Samuel L. Manzello, Sayaka Suzuki, Koji Kagiya, Junichi Suzuki, Yoshihiko Hayashi
A series of experiments were conducted to examine ignition of mulch beds to continuous, wind-driven firebrand showers. Shredded hardwood mulch, fitted in beds 1.2 m by 1.2 m with a thickness of 51 mm, was attached to a non-combustible re-entrant corner

The Use of Elevators for Evacuation in Fire Emergencies in International Buildings

July 21, 2014
Author(s)
Max T. Kinateder, Hidemi Omori, Erica D. Kuligowski
The purpose of this report is to provide an overview of elevator evacuation from high-rise buildings with a focus on the safety of mobility impaired occupants. It addresses the specifics of elevator evacuation as well as relevant building codes and its

Quantitative Infrared Imaging of Impinging Turbulent Buoyant Diffusion Flames

July 2, 2014
Author(s)
Randall J. McDermott, Ashish Newale, Brent Rankin, Harshad Lalit, Jay P. Gore
Radiation from buoyant diffusion flames with and without impingement on a flat plate is studied using a unique quantitative comparison of measured and simulated images. The coupling between the stagnation boundary layer and upstream buoyant shear layer

BEHAVIOR OF STEEL COMPONENTS SUBJECTED TO LOCALIZED FIRE

June 11, 2014
Author(s)
Chao Zhang, John L. Gross, Lisa Y. Choe
Recent numerical studies on the behavior of steel components subjected to a localized fire are presented. Sequentially coupled thermo-mechanical simulations were conducted to predict the steel temperature distribution, the deformation mode and failure

USA - Characteristics, Impacts, and Future Directions

June 11, 2014
Author(s)
Sarah Slaughter, Douglas Thomas, Robert E. Chapman
Investments in the built environment provide the basis for civil society and commerce, and construction is an engine of growth for the U.S. economy, equaling approximately 3 % to 5 % of GDP. Current U.S. annual expenditures for construction-related R&D are
