Estimating real-time infiltration for use in residential ventilation control

June 18, 2019

Author(s)

Lisa Ng, Stephen M. Zimmerman, Jeremy Good, Brian Tool, Steven Emmerich, Andrew Persily

Minimum outdoor air ventilation rates specified in standards such as ASHRAE Standard 62.2 are generally based on envelope airtightness, building floor area, geographical location, and number of occupants. To meet ventilation requirements in practice

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

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

Evaluating IAQ and Energy Impacts of Ventilation in a Net-Zero Energy House Using a Coupled Model

December 18, 2017

Author(s)

Lisa C. Ng, Dustin G. Poppendieck, William S. Dols, Steven J. Emmerich

The National Institute of Standards and Technology constructed the Net-Zero Energy (NZE) Residential Test Facility to support the development and adoption of cost-effective NZE designs and technologies. Source control approaches were implemented that

Weather Correlations to Calculate Infiltration Rates for U.S Commercial Building Energy Models

November 14, 2017

Author(s)

Lisa C. Ng, Nelson Ojeda-Quiles, William S. Dols, Steven J. Emmerich

As building envelope performance and heating, ventilating and air-conditioning (HVAC) equipment efficiencies are improved to reduce building energy use, a greater percentage of the total energy loss can occur through building envelope leakage. Although the

Model Validation Study of Carbon Monoxide Transport due to Portable Generator Operation in an Attached Garage

October 6, 2017

Author(s)

Steven J. Emmerich, William S. Dols

NIST conducted a series of tests to characterize the indoor CO concentrations resulting from portable generators operating in the attached garage of a house under various use and environmental conditions. An extensive model validation effort using the

Characterization of Emissions from Spray Polyurethane Foam - Final Report to U.S. Consumer Product Safety Commission

September 8, 2017

Author(s)

Dustin G. Poppendieck, Mengyan Gong, Steven J. Emmerich

Spray polyurethane foam (SPF) insulation increases building energy efficiency by reducing conductive and convective heat losses through the building envelope and is used in both new construction and retrofit applications. Health complaints relating to

Measured Carbon Monoxide Concentrations from Stock and Reduced- Emission Prototype Portable Generators Operated in an Attached Garage

June 16, 2017

Author(s)

Steven Emmerich, Leon Wang

There is concern about the hazard of acute residential CO exposures from portable gasoline powered generators that can result in death or serious adverse health effects in exposed individuals. The U.S. Consumer Product Safety Commission subsequently

Literature review on field study of ventilation and indoor air quality performance verification in high- performance commercial buildings in North America

March 31, 2017

Author(s)

Steven Emmerich, Kevin Y. Teichman, Andrew K. Persily

In this paper, we summarize the results of field studies to evaluate the ventilation and indoor air quality (IAQ) performance in high-performance commercial (non-industrial, non-residential) buildings in North America. We show that the number of such

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
