Online Airtightness Calculator for the US, Canada and China

December 15, 2016
Author(s)
Som Shrestha, Lisa Ng, Steven Emmerich, Diana Hun, Laverne Dalgleish
The contribution of air leakage to heating and cooling loads has been increasing as the thermal resistance of building envelopes continues to improve. Easy-to-access data are needed to convince building owners and contractors that enhancing the

Investigating Firebrand Accumulation over Various Scales

November 22, 2016
Author(s)
Samuel Manzello, Sayaka Suzuki
As structures are exposed to wind, stagnation planes are produced around structures. Using full-scale experiments, the authors demonstrated that firebrands may accumulate in these stagnation planes. In a subsequent full-scale study performed by the authors

Smoldering and Flame Resistant Textiles via Conformal Barrier Formation

November 2, 2016
Author(s)
Mauro Zammarano, Shonali Nazare, John R. Shields, Kathleen M. Hoffman, Rick D. Davis
A durable and flexible silicone-based backcoating (halogen and formaldehyde free) is applied to the backside of an otherwise smoldering-prone and flammable fabric. When exposed to fire, cyclic siloxanes (produced by thermal decomposition of the backcoating

Energetics of Small and Moderate-Scale Gaseous Pool Fires

November 1, 2016
Author(s)
Anthony P. Hamins
A series of measurements were made to characterize the global properties of moderate-sized pool fires steadily burning in a quiescent environment. A wide range of parameters were considered including lightly and heavily sooting hydrocarbon fuels (methane

The Structure of a Moderate-Scale Methanol Pool Fire

November 1, 2016
Author(s)
Anthony P. Hamins, Andrew Lock
A series of measurements was made to characterize the structure of a moderate-sized methanol pool fire steadily burning in a quiescent environment. Time averaged local measurements of temperature and gas species concentrations were made in a steadily

Measuring Temperature in Emission Testing Micro-chambers

October 24, 2016
Author(s)
Dustin G. Poppendieck, Edwin Guillermo, Havishk Tripathi
ASTM subcommittee D22.05 on Indoor Air is working to finalize WK40293: Standard Test Method for Estimating Chemical Emissions from Spray Polyurethane Foam (SPF) Insulation Using Micro-Scale Environmental Test Chambers. One issue in WK40293 is determining

Characterization of Emissions from a Non-Ideal Spray Polyurethane Foam Sample

October 17, 2016
Author(s)
Dustin G. Poppendieck, Mengyan Gong, Lauren E. Lawson, Steven J. Emmerich
Many homeowners and government programs are using insulating products, such as SPF, at a growing rateto increase the energy efficiency of their residences and other constructed buildings. Retrofitting or addition of foam insulation in new construction is

Lessons Learned from Spray Polyurethane Foam Emission Testing using Micro-chambers

October 16, 2016
Author(s)
Dustin Poppendieck, Mengyan Gong, Lauren E. Lawson
Both governmental agencies and the SPF industry consortium have sought more information on potential chemical emissions from SPF to better understand any potential occupant exposures and health impacts. This research was designed to contribute to the

Gas-Phase Interactions of Phosphorus Containing Compounds with Cup-Burner Diffusion Flames

September 20, 2016
Author(s)
Gregory T. Linteris, Fumiaki Takahashi, Viswanath R. Katta, Valeri I. Babushok
The effects of phosphorus-containing compounds (PCC) on the extinguishment and structure of methane-air coflow diffusion flames, in the cup-burner configuration, have been studied computationally. Dimethyl methylphosphonate (DMMP), trimethyl phosphate (TMP

NIST Programs to Advance Accurate, Internationally-Recognized Stack Emissions Measurements

September 15, 2016
Author(s)
Aaron Johnson, Iosif Isaakovich Shinder, Rodney A. Bryant, JohnPaul R. Abbott, Keith A. Gillis, Joey Boyd, James Filla, Michael R. Moldover
Accurate flow measurements are essential to quantify the amount of greenhouse gases (GHGs) and other pollutants emitted from power plant stacks. Although protocols have been developed, the uncertainty of stack flow measurements has not been documented. 

Characterizing Indoor Air Quality Performance Using a Graphical Approach

September 14, 2016
Author(s)
Kevin Y. Teichman, Andrew Persily, Steven Emmerich
In this paper, we describe and demonstrate an approach to illustrate the performance of buildings with respect to indoor air quality (IAQ). In the absence of an adequate or agreed-upon IAQ metric(s), we describe a graphical approach to presenting IAQ

Evaluating the Initial Field Performance of HVAC-Cx for Air Handling Units

August 17, 2016
Author(s)
Natascha S. Milesi-Ferretti, Michael A. Galler, Steven T. Bushby
Automated commissioning tools facilitate the ongoing commissioning process to improve occupant comfort, ensure the persistence of correct system operation, and reduce energy consumption. These tools decrease the time and the skill level required to carry

Perspectives of Occupants with Mobility Impairments on Fire Evacuation and Elevators

August 15, 2016
Author(s)
Kathryn M. Butler, Susanne M. Furman, Erica D. Kuligowski, Richard D. Peacock
The purpose of this report is to provide guidance for designers, building managers, and fire emergency personnel on how to improve communication, procedures, and elevator usage during fire emergencies, based on a study of the evacuation experiences of

Alternate Substrates for Measuring Cigarette Ignition Propensity Using ASTM E 2187

August 11, 2016
Author(s)
Richard G. Gann, Edward J. Hnetkovsky, William F. Guthrie
ASTM E 2187 has become the internationally referenced standard for designing and specifying less fire-prone cigarettes. In this Standard, a lit cigarette is placed on a substrate consisting of a number of layers of filter paper. The metric is whether the

Interlaboratory Study of an Alternate Substrate for Use in ASTM E 2187

August 11, 2016
Author(s)
Richard G. Gann, Morgan Bruns, Edward J. Hnetkovsky, William F. Guthrie
ASTM E 2187 has become the internationally referenced standard for designing and specifying less fire-prone cigarettes. In this test method, a lit cigarette is laid on multiple layers of filter paper, and the observer identifies whether the cigarette burns

Thermal Exposure Sensor for Fire Fighters - full-Scale Performance Experiments

July 26, 2016
