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

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

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

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

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

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

INDOOR ENVIRONMENTAL RESILIENCE: A REVIEW AND DISCUSSION

July 19, 2015
Author(s)
Andrew K. Persily, Steven J. Emmerich
NIST is developing a planning guide to define 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 (IEQ) either through

Indoor Environmental Resilience: White Paper

Improving infiltration modeling in commercial building energy models

May 15, 2015
Author(s)
Lisa C. Ng, Andrew K. Persily, Steven J. Emmerich
As building envelope performance and HVAC equipment efficiencies are increasingly 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

Indoor Air Quality in High-Performing Building Case Studies: Got Data?

May 12, 2015
Author(s)
Kevin Y. Teichman, Andrew K. Persily, Steven J. Emmerich
In this paper, we review how indoor air quality (IAQ) has been addressed in case studies of high-performing buildings (HPBs), specifically the case studies described in ASHRAE’s “High Performing Buildings” magazine. We find that nearly all of the reported

CONTAM To EnergyPlus Infiltration Features of the CONTAM Results Export Tool

March 30, 2015

Brian J. Polidoro, Lisa C. Ng, William S. Dols, Steven J. Emmerich, Andrew K. Persily
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

HVACR Editorial for IAQ 2013 Special Issue

January 23, 2015
Author(s)
Hal Levin, Steven Emmerich
The papers in this issue were selected from presentations made at the ASHRAE IAQ 2013: Environmental Health in Low Energy Buildings conference held in Vancouver Canada in October 2013. The conference was held specifically to review the state of knowledge
