Vidaris uses Hygrothermal Analyses to identify the temperature and moisture conditions within a building component, based on the given interior/exterior conditions and material properties.
WUFI facilitates one and two dimensional heat and moisture transport in building components over a specified period of time. The program takes into account climate data – including driving rain, annual temperature, relative humidity, and solar radiation – to determine the behavior of a component exposed to weather.
Vidaris uses Hygrothermal Analyses to identify the temperature and moisture conditions within a building component, based on the given interior/exterior conditions and material properties. The analysis are static, constant conditions, or transient.
Vidaris has performed 2-dimensional vapor migration analysis using WUFI on a wide variety of new and existing masonry construction, including solid brick wall, brick cavity wall, and various compositions of brick, terracotta, concrete or stone construction.
The analysis is utilized to inform the design process as to how best to approach existing (or new) façade systems relative to insulation type, thickness, and effectiveness, as well as air and vapor control layer characteristics, performance capabilities and overall wall assembly freeze/thaw cycling. Where appropriate, we have also performed absorption testing at exterior surfaces and/or can we can work with materials testing laboratories to further define existing material properties so as to better approximate actual conditions in the modeled material.
The WUFI modeling is focused on optimizing details, allowing one to:
The program takes into account:
The WUFI analysis is recommended over the standard ASHRAE Dewpoint and Glaser methods because it incorporates time dependence, drying potential and the effects of moisture storage capacity.
Vidaris professionals are architects and engineers, with experience in design, construction and operations. We focus on solutions that integrate both the envelopes and HVAC, to (a) improve the marketability of the projects and (b) reduce risk for both design professionals and developers.
