WINDOW 3. 1: A PC program for analyzing window thermal performance: Program description and tutorial
WINDOW 3.1 is a public-domain computer program developed by the Windows and Daylighting Group at Lawrence Berkeley Laboratory for analyzing heat transfer through window systems. The program uses an iterative technique to calculate the one-dimensional temperature profile across a user-defined window system. From this data, window system performance indices, e.g., U-value and shading coefficients, are calculated. WINDOW 2.0, incorporates several technical additions and many new user-friendly features, while continuing to provide a consistent and versatile heat transfer analysis method. The user can vary environmental conditions, window tilt, number of glazing layers, layer properties (thermal infrared, solar and visible optical properties, and thermal conductance), gap widths, composition of gap gas or gas mixture fill, and spacer and frame materials. 7 refs., 3 figs.
