FRAME4

FRAME4 logo.

Uses two-dimensional finite-volume analysis to evaluate heat transfer through complex building components. FRAME is part of the FRAMEplus toolkit for analysis of windows, doors, walls, roofs and below-grade assemblies. Users draw building components as assemblies of cross-sections. Any interior or exterior environmental condition can be applied. .DXF files and VISION4 files can be imported to speed up data entry. Results are displayed graphically and are used to determine heat transfer, potential for thermal bridging and surface condensation. The FRAME4 simulations (when combined with VISION) are an equal alternative to testing to determine the U-value and solar heat gain coefficient of windows and doors. The U.S. National Fenestration Rating Council and Canadian Standard Association recognize FRAME as the only acceptable computer program to determine heat transfer through opaque portions of windows, doors and curtainwalls. FRAME was used to generate window and door U-values in the ASHRAE Handbook of Fundamentals.

Keywords

fenestration, framing, heat transfer, building components, thermal characteristics

Validation/Testing

N/A

Expertise Required

A basic understanding of heat transfer and computer familiarity is helpful.

Users

Over two thousand users in 22 countries.

Audience

Window manufacturers, engineers, architects, analysts determining window ratings for NFRC and CSA certification.

Input

The user draws building components as an assembly of unique cross-sections of uniform material. The program contains a library of over 100 materials and calculates heat transfer for internal cavities. Mouse or cursor input. FRAME can import .DXF format CAD files, VISION4 and WINDOW files.

Output

U-values, local heat flow and temperature. A graphical display of heat flow and isotherm plots is superimposed on component drawing.

Computer Platform

PC-compatible 386 or higher, running in DOS or Windows 95.

Programming Language

C

Strengths

FRAME is simple and easy to use. Mouse or cursor input, pull-down menus, point-and-click icons. FRAME runs are very rapid. It has an extensive library of building materials and pre-drawn spacer assemblies.

Weaknesses

Because of the complexity of some assemblies (e.g., window frame), it can take up to one to two hours to draw the assembly to be simulated.
