An Improved Method Of Modeling Infiltration In Commercial Building Energy Models

June 1, 2016
Author(s)
Lisa C. Ng, Steven J. Emmerich, Andrew K. Persily
Different strategies for improving building envelope thermal performance are being implemented in commercial building design and construction as well as being incorporated into ASHRAE standards and other design requirements. The energy impacts of

Flame Retardant Emissions from Spray Polyurethane Foam Insulation

April 20, 2016
Author(s)
Dustin G. Poppendieck, Adam P. Blickley, Matthew Schlegel, Angelica Connor
The desire to build more energy efficient homes in the United States has led to the expansion of the residential spray polyurethane foam (SPF) insulation industry. Upon application of SPF, reacting chemicals form expanding polyurethane foam that fills

Formaldehyde Concentrations in a Net-Zero Energy House: Real-time Monitoring and Simulation

April 19, 2016
Author(s)
Dustin Poppendieck, Shahana S. Khurshid, William Stuart Dols, Lisa Ng, Brian Polidoro, Steven Emmerich
Measured real-time formaldehyde concentrations in a net-zero energy house were compared to simulated concentrations from a recently-developed, coupled building energy and airflow/indoor air quality model. Measured and simulated formaldehyde concentrations

Measuring Flame Retardant Emissions from Spray Polyurethane Foam in a Home

April 19, 2016
Author(s)
Dustin Poppendieck, Angelica Connor
The use of spray polyurethane foam (SPF) insulation in the United States is increasing. The primary flame retardant used in SPF, Tris (1-chloro-2-propyl) phosphate (TCPP), has been detected in micro-chamber emission experiments investigating SPF. However

Carbon Dioxide Generation Rates for Building Occupants

April 18, 2016
Author(s)
Andrew K. Persily, Lilian de Jonge
Indoor carbon dioxide (CO2) concentrations have been used for decades to characterize building ventilation and indoor air quality. Many of these applications require estimates of CO2 generation rates from the building occupants, which are currently based

Characterizing Uncertainty of a Formaldehyde Reference Standard

April 18, 2016
Author(s)
Dustin Poppendieck
High performance buildings need to be energy efficient and provide adequate ventilation for indoor air quality, which can be made easier with low emitting building materials. Based in part on these motivations, the United States Environmental Protection

Development of Two Fine Particulate Matter Standard Reference Materials ( 4 mm and 10 mm) for the Determination of Organic and Inorganic Constituents

April 13, 2016
Author(s)
Michele M. Schantz, Danielle Cleveland, N. Alan Heckert, John Kucklick, Stefan D. Leigh, Stephen E. Long, Jennifer Lynch, Karen E. Murphy, Rabia Oflaz, Adam L. Pintar, Barbara J. Porter, Savelas A. Rabb, Stacy Schuur, Stephen Wise, Rolf L. Zeisler
Two new Standard Reference Materials (SRMs), SRM 2786 Fine Particulate Matter ( 4 µm) and SRM 2787 Fine Particulate Matter ( 10 µm) have been developed in support of the US Environmental Protection Agency's National Ambient Air Quality Standards for

CONTAM RESULTS EXPORT TOOL

March 9, 2016
Author(s)
Brian Polidoro, Lisa Ng, William Stuart Dols
CONTAM is a multizone indoor air quality and ventilation analysis program developed by the National Institute of Standards and Technology (NIST). Since CONTAM simulation files are binary and not human-readable, the CONTAM Results Export Tool was created to

Characterizing Indoor Air- Quality Performance Using a Graphical Approach

March 8, 2016
Author(s)
Kevin Y. Teichman, Cynthia H. Reed, Steven J. Emmerich
In this paper, we describe and demonstrate a graphical approach to illustrating the indoor air quality (IAQ) performance of high-performing buildings. We start by describing previous efforts to establish IAQ and indoor environmental quality (IEQ) metrics

THE INDOOR ENVIRONMENTAL SIDE OF RESILIENCE

February 1, 2016
Author(s)
Andrew K. Persily, Steven J. Emmerich
NIST is developing a framework to define programs and strategies to increase community-based resilience in the face of a broad range of natural disasters and other extreme events. Many of these events will affect indoor environmental quality either through

Energy Use Consequences of Ventilating a Net-Zero Energy House

December 2, 2015
Author(s)
Lisa C. Ng, William V. Payne
A Net-Zero Energy Residential Test Facility (NZERTF) has been constructed at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland to demonstrate that a home similar in size, aesthetics, and amenities to those in the

Infiltration and Ventilation in a Very Tight Home

September 23, 2015
Author(s)
Lisa C. Ng, Andrew K. Persily, 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. Key design objectives

CONTAM User Guide and Program Documentation Version 3.2

September 4, 2015
Author(s)
William S. Dols, Brian J. Polidoro
This manual describes the computer program CONTAM version 3.2 developed by NIST. CONTAM is a multizone indoor air quality and ventilation analysis program designed to help you determine: airflow rates and pressures – infiltration, exfiltration, and room-to
