Quantifying Wind-Driven Firebrand Production from Roofing Assembly Combustion

July 16, 2018
Author(s)
Samuel L. Manzello, Sayaka Suzuki, Tomohiro Naruse
Large outdoor fires present a risk to the built environment. Examples often in the international media reports are wildfires that spread into communities, referred to as Wildland-Urban Interface (WUI) fires. Other examples are large urban fires including

User Instructions and Technical Details for 500 mm GHP Simulation Programs

Author(s)
William C. Thomas
This report is a supplement to the paper published as "Transient Thermal Response of an Extended Temperature Range 500-mm diameter Guarded Hot-plate Apparatus" by Thomas and Zarr (2018), hereafter referred to as the "paper." The paper emphasizes the use of

Performance Testing of Hydraulic Cements: Measuring Sulfate Resistance

May 25, 2018
Author(s)
Chiara F. Ferraris, Paul E. Stutzman, Max A. Peltz
The sulfate resistance of cements used in the construction industry is traditionally assessed by measuring the expansion of a prism of 280 mm (11inch) length and 25 mm (1 inch) square cross section immersed in a sodium sulfate solution for at least one

Ventilation, IAQ and Filtration in a Net Zero Energy House

May 24, 2018
Author(s)
Andrew K. Persily, Lisa C. Ng, Dustin G. Poppendieck, Steven J. Emmerich
The Net Zero Energy Residential Test Facility (NZERTF) was constructed at the National Institute of Standards and Technology (NIST) to support the development and adoption of cost-effective net zero energy designs and technologies. The 250 m2 two-story

Burning Velocities of Marginally Flammable Refrigerant-Air Mixtures

May 1, 2018
Author(s)
Gregory T. Linteris
Refrigerant working fluids have been predicted to be large contributors to the increase in radiative forcing of the earth. Consequently, existing compounds will soon be phased out. Low- GWP replacements exist, but they tend to be mildly flammable, and

Balancing Energy and IAQ: NIST Net-Zero Energy Residential Test Facility

April 18, 2018
Author(s)
Lisa C. Ng, Dustin G. Poppendieck, William S. Dols, Brian P. Dougherty, Steven J. Emmerich
Buildings used 39 % of all energy used in the United States in 2017, with residential buildings and commercial buildings accounting for 20 % and 19% (EIA 2018) respectively. Zero energy buildings have the potential to help extend and accelerate the recent
