IBPSA-USA Webinar - New IAQ Modeling Software from NIST

*Earn 1 AIA HSW Learning Unit! *

This two-part presentation introduces the indoor air quality modeling
software CONTAM and the web-based tool FaTIMA for modeling the Fate and
Transport of Indoor Microbiological Aerosols. These publicly available
tools are developed by the National Institute of Standards and Technology
(NIST).
In the first part we will introduce the concept of multizone airflow and
contaminant transport modeling and present the capabilities of CONTAM. We
will then touch on the advanced modeling capabilities that include coupling
between CONTAM and computational fluid dynamics (CFD) and co-simulation
between CONTAM and the energy modeling programs EnergyPlus and TRNSYS.

In the second part we will present FaTIMA, which is a recently developed,
web-based front end to the CONTAM simulation engine, ContamX. We will
introduce the model capabilities, user inputs, and results generated. We
will then present the use of the tool in evaluating the relative
effectiveness of various measures to reduce exposure to infectious aerosols
including: wearing of face coverings, increasing ventilation, increasing
filtration, and using portable air cleaners. This presentation will help
modelers, building owners, and facility managers to understand and apply
FaTIMA to their own situations.

*Learning Objectives (Approved for 1 AIA HSW Learning Unit): *
Attendees will be able to:

- Describe NIST-developed, whole-building indoor air quality (IAQ)
modeling software, CONTAM, and related simulation tools
- Understand the fundamentals of multizone modeling and advanced
capabilities of CONTAM software including coupled energy, airflow, and IAQ
analysis
- Describe the web-based software FaTIMA including its development,
inputs, and outputs.
- Apply FaTIMA to evaluate aerosol exposure as influenced by HVAC system
type, ventilation rates, filtration, and other mitigation strategies.

*Speaker Bios:*

Both Lisa Ng and W. Stuart Dols are mechanical engineers in the Indoor Air
Quality and Ventilation Group of the Energy and Environment Division of the
Engineering Laboratory at the National Institute of Standards and
Technology (NIST).

*Lisa* graduated from the
Department of Civil and Architectural Engineering at Drexel University with
her bachelor?s and Ph.D. She works on airflow and indoor air quality
performance in buildings, with a focus on low-energy buildings as well as
energy efficiency design and operation strategies in general. She is active
in the development of strategies for incorporating more accurate
infiltration estimates in building energy models and the application of
multizone airflow and indoor air quality (IAQ) models to a range of
building performance issues.

*Stuart* has a BS in
Mechanical Engineering from the University of Maryland and a MS in Computer
Science from Johns Hopkins University. He currently works on developing,
maintaining, and applying building simulation tools including the CONTAM
multi-zone airflow and contaminant transport simulation program and related
software. His current areas of focus include developing and applying the
coupling between CONTAM and the energy analysis tools EnergyPlus and
TRNSYS. He also led the recent development of the web-based simulation tool
to simulate the Fate and Transport of Indoor Microbiological Aerosols
(FaTIMA).
