**Simulating Water: A Presentation of Hygrothermal Modeling Case Studies*
*

Location:* Steven Winter Associates, Inc., 307 Seventh Avenue, Suite 1901,
New York, NY 10001. Tel. 212.564.5800 (main)*

Date & Time:* Thursday, September 6, 2012 - 6:00-8:00 PM.
*
6:00-6:30 PM    Networking

6:30-7:00 PM    Hygrothermal Modeling Methodology*
*Cheryl M. Saldanha, LEED GA – Building Technology, Simpson Gumpertz & Heger
*

*Description*

Modern buildings typically contain envelope systems that require specific
layers to control condensation due to moisture migration and/or air
leakage, dedicated waterproofing systems to protect moisture-sensitive
backup materials (e.g., wood and gypsum-based products), and thermal
insulation to control heat losses and gains. Consequently, building codes
include provisions for these systems in new construction, and in some
cases, renovation projects. As such, architecture and consulting firms
frequently turn to hygrothermal modeling to determine the optimal
arrangement of these layers. This presentation will introduce the
parameters to consider when setting up a model, and through several project
examples, demonstrate how hygrothermal modeling can be used to develop
assemblies with a low risk for moisture-related problems.  Also, critical
to the process, we will touch on some of the limitations and assumptions
made when developing a hygrothermal model.

*About the Speaker*

Cheryl Saldanha works with Simpson Gumpertz & Heger Inc. in New York City.
Cheryl specializes in building science and building-envelope performance,
including the simulation of heat, air, and moisture migration through
assemblies.  She has investigated building enclosure and mechanical system
failures, and designed remedial repairs.

*7:00-7:15 PM    Q & A

7:15-7:45 PM    Analyzing Moisture in Brick Masonry Walls*
*Pallavi Mantha, LEED AP BD+C – Building Systems Analyst, Steven Winter
Associates, Inc.

Description*

The thermal resistance provided by un-insulated brick walls (R-3 to R-5) is
often insufficient for occupant thermal comfort and energy efficiency in
most climates. Retrofits to brick buildings are usually conducted from the
interior due to both financial and social pressure to preserve the exterior
façade. This seminar will focus on the thermal and hygric behavior of brick
masonry walls with interior retrofit strategies. Key inputs that affect
results and a methodology to comply with failure criteria are discussed.
Analysis and results from research conducted by SWA will be shared.

*About the Speaker*

Pallavi Mantha works with Steven Winter Associates on high performance
buildings and research projects. Her body of work spans numerous
single-family, multifamily and commercial projects. She provides modeling
support for Building America, NYSERDA Multifamily Performance Program
(MPP), Energy Star Multifamily High-Rise (MFHR) and DOE - Commercial
Building Partnership (CBP).

With funding from the U.S. Department of Housing and Urban Development and
DOE’s Building America Program, she has conducted research and published
papers on topics such as internal moisture loads in homes, High-R walls and
hygrothermal performance of hybrid wall systems. Her areas of expertise
include whole building energy modeling, high performance component
modeling, daylighting, passive solar and renewable energy strategies,
building systems research, and data visualization.**
