The Fenestration and Glazing Industry Alliance (FGIA) has released a new publication addressing aspects of the finite element (FE) thermal modeling process.
This procedure is often used to predict interior surface temperatures on fenestration including non-residential windows, terrace and patio doors, curtain wall, storefront, and entrances. AAMA 515-19, “Voluntary Procedure for Determination of Fenestration Surface Temperatures by THERM Finite Element Modeling,” an FGIA standard, is now available for purchase.
This voluntary procedure helps designers determine what temperatures and film coefficients to use when running a project-specific condensation analysis. Per AAMA 515, condensation will occur on any interior surface that falls below the dew point temperature of interior ambient air. “Condensation can be unsightly, unsanitary, and over long periods of time can damage adjacent building materials,” according to an FGIA news release.
“This new, voluntary procedure, a result of seven years of detailed development, is intended to make application of the software tool uniform between users,” said Steve Fronek (Wausau Window and Wall Systems), chair of the Architectural Finite Element Thermal Modeling Task Group. “It addresses key variables, such as boundary conditions, substrates and THERM parameters, as well as the accuracy of modeling and testing. The scope is clearly outlined and guidance provided for the specifier.”
