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

July 16, 2015
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

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
Author(s)
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

Carbon Monoxide Exposure from Portable Generators

October 28, 2014
Author(s)
Steven J. Emmerich, Andrew K. Persily, Liangzhu Wang
Serious concerns exist about the hazard of acute residential carbon monoxide (CO) exposures from portable gasoline-powered generators, which can result in death or serious adverse health effects. As of April 23, 2013 and as shown in Figure 1, the U.S

Infiltration in energy modeling: a simple equation made better

August 8, 2014
Author(s)
Lisa C. Ng, Andrew K. Persily, Steven J. Emmerich
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

Simulation Study of Carbon Monoxide Exposure from Portable Generators in U.S. Residences

August 6, 2014
Author(s)
Andrew K. Persily, Steven J. Emmerich, Yanling Wang, Brian J. Polidoro
A simulation study was conducted to evaluate indoor CO exposures as a function of portable generator location and CO emission rate in order to support the development of potential CO emission limits for generators. These simulations employed the multizone

An improved method of modeling infiltration in commercial building energy models

April 28, 2014
Author(s)
Lisa C. Ng, Steven J. Emmerich, Andrew K. Persily
As various strategies for improving building envelope and HVAC equipment efficiencies are increasingly used to reduce building energy use, a greater percentage of energy loss can occur through building envelope leakage. Although the energy impacts of

IAQ 2013 Tools Topic Overview

February 20, 2014
Author(s)
Steven J. Emmerich, Larry Schoen
The complex relationships between indoor and outdoor environmental conditions, coupled with the impacts of climate change, make it more important than ever before that buildings be comfortable and healthy for the occupants yet also energy efficient. This

Environmental Health in Low Energy Buildings Topic Overview

February 11, 2014
Author(s)
Steven J. Emmerich, Hal Levin
Besides providing thermal comfort and acceptable indoor environmental quality (IEQ), the designers of buildings and other enclosed spaces are increasingly challenged to provide a healthy environment in an energy efficient manner. Increasing pressure to
