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

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

Heat pump concepts for nZEB – Technology developments, design tools and testing of heat pump systems for nZEB in the USA, Country report IEA HPT Annex 40 Task 2, Task 3 and Task 4 of the USA

William V. Payne, Arthur H. Fanney, William M. Healy, Joshua D. Kneifel, Tania Ullah, Farhad Omar, Steven T. Bushby, Brian P. Dougherty, Dustin G. Poppendieck, Lisa C. Ng
The IEA HPT Annex 40 "Heat pump concepts for Nearly Zero Energy Buildings" deals with the application of heat pumps as a core component of the HVAC system for Nearly or Net Zero energy buildings (NZEB). This report covers Task 2 on the system comparison

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

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
