INTRODUCTION

1.1. Overview
THERM is a Microsoft Windows™-based computer program developed at Lawrence Berkeley National Laboratory (LBNL) for use by building component manufacturers, engineers, educators, students, architects, and others interested in two-dimensional heat transfer. Using THERM, you can model two-dimensional heat-transfer effects in building components such as windows, walls, foundations, roofs, and doors, appliances, and other products where thermal bridges are of concern. THERM’s heat-transfer analysis allows you to evaluate a product’s energy efficiency and local temperature patterns, which may relate directly to problems with condensation, moisture damage, and structural integrity.
THERM’s two-dimensional conduction heat-transfer analysis is based on the finite-element method, which can model the complicated geometries of building products. The program’s graphic interface allows you to draw cross sections of products or components to be analyzed. To create the cross sections, you can trace imported files in DXF or bitmap format, or input the geometry from known dimensions. Each cross section is represented by a combination of polygons. The material properties are defined for each polygon and the environmental conditions to which the component is exposed are defined by the boundary conditions surrounding the cross section. Once the model is created, the remaining analysis (mesher and heat transfer) is automatic. You can view results from THERM in several forms, including U-factors, isotherms, heat-flux vectors, and local temperatures.
THERM’s results can be used to define the frame elements in the Berkeley Lab WINDOW program’s centerof-glass optical and thermal models to determine total window product U-factors and Solar Heat Gain Coefficients.

Forum (Google Group) at https://groups.google.com/g/LBNL-THERM where you can post and reply to questions about the program.

1.2. THERM 8.0 Transient Moisture Model
The THERM simulation engine been extended to model time dependent (transient) simulations (a “time domain” has been added to THERM’s original 2-D Finite Element Numerical Model (FEM)), and a moisture transfer model has been added.
The transient thermal and moisture simulation engine in THERM (called HygroThermFEM) allows modeling of thermal bridges and non-homogeneities in building construction without approximation. Such elements are primary pathways and causes for condensation and moisture in building and it is important to model them correctly in a thermal/moisture analysis. By failing to account for the moisture characteristics in the thermal envelope, designers and building can introduce problems that endanger the health and safety of building occupants as well as the durability of the building itself.
The HygroTHERMFEM model in THERM 8 will allow building simulation practitioners to accurately model wall, roof, foundation constructions taking into account both the thermal and moisture characteristics of those constructions.

1.3. Changes from THERM 7 to THERM 8.0
The following are the changes made to THERM 8 to accommodate the new moisture model:
 Simulation engine options (File / Properties)
 Steady-state without moisture (THERM 7)
 Transient/moisture
 Material and Boundary Condition Libraries
 The Material and Boundary Condition Libraries for the transient / moisture model are stored in
the XML file format and have a new grid view
 New mesher that is able to handle more complex geometry
 Visualization “window” for viewing the moisture results
This document is not a complete THERM user manual, but instead contains the changes made to THERM 8 for the Transient Moisture Model.

Transient Moisture and Thermal Simulations

2.1. Overview
THERM allows modeling both transient moisture and thermal simulations, as well as stead-state thermal
simulations.
The sections below describe the settings for transient moisture and thermal simulations.
2.2. File / Properties
The File / Properties dialog box controls what model is used for a given file. All the settings in the three tabs of the File / Properties dialog box are saved with individual files, not as program-level settings.

Calculation Options tab
Below is a description of the fields in the File / Properties / Calculation Options tab.
