Class SeedWindow

Whether the window faces exterior conditions or an enclosed unheated space.

For EnerGuide: unheated maps to HOT2000's adjacent enclosed space handling.

Optional. It is consisted of a window's "entity" and "shgc_entity" in one place for convenience and certain operations.

Type of window blinds or shading devices.

Used to adjust solar gain calculations, and the added r-value when the exterior blinds are closed. Different blind types have different solar reduction factors.

For F280: Affects cooling load calculations by reducing solar gain. Interior blinds have less effect than exterior or reflective types.

For EnerGuide: No effect for the interior options, because it relates to occupant behavior.

Cardinal orientation of the window.

Each direction has specific solar radiation values applied to its windows.

For F280: Affects solar correction factors and the L-factor in cooling load calculations. Different orientations have different solar radiation intensity values.

For EnerGuide: Impacts the score, usually by offsetting the need for mechanical heating. Converted to HOT2000 direction codes for solar gain calculations. Exported as FacingDirection.

Material composition of the window (glass, frame, etc.).

Used to determine thermal properties (R-value) and also modifies SHGC for window heat loss calculations.

For F280: Core parameter for conductive heat loss calculations

For EnerGuide: Is used to calculated the R-Value and SHGC of the exact window size, because the entity data is coming from a standard size. Exported to HOT2000 as the window construction type with its R-value properties for heat loss/gain calculations.

Height of the window in meters.

Used with width to calculate window area for heat loss, solar gain, and total_window_area calculations.

For F280: Used to calculate window area for heat loss and solar gain calculations.

For EnerGuide: Is used for adjusting SHGC and R-value from the test data. Exported to HOT2000 as height attribute in window dimensions.

Height from top of window to overhang in meters.

Used with overhang_width to calculate shading effects for solar gain reduction.

For F280 and EnerGuide: Determines effectiveness of the overhang shading. Smaller heights increase shading effectiveness.

Width of any overhang above the window in meters.

Used in solar gain calculations to determine shading effects that reduce solar heat gain.

For F280: Affects solar gain by providing shade. Wider overhangs reduce cooling loads by blocking direct sun, especially for south-facing windows.

For EnerGuide: As overhangWidth attribute, affecting solar gain calculations with shading.

Solar heat gain coefficient properties for the window.

Used for calculating solar gain through windows based on orientation and SHGC value.

For F280: Critical for cooling load calculations. The SHGC determines how much solar radiation enters through the window and becomes heat.

For EnerGuide: Is used to calculated the SHGC of the exact window size, because the entity data is coming from a standard size. Exported to HOT2000 as the SHGC attribute in window elements, affecting solar gain in both heating and cooling seasons.

Tilt angle of the window from horizontal in degrees. Usually it is 90 degrees.

Used to adjust solar gain calculations for non-vertical windows. Affects the effective solar radiation.

For F280: Impacts solar gain calculations. Non-vertical windows receive different solar radiation based on tilt angle, even though the standard does not explicitly define a calculation method for them.

For EnerGuide: Affects solar gain calcs. Exported to HOT2000 as tilt attribute.

Extended type enumeration for wall windows and door-windows. Puts all of them in one place following EnerGuide convention.

Width of the window in meters.

Used with height to calculate window area for heat loss, solar gain, and total_window_area calculations.

For F280: Used to calculate window area for heat loss and solar gain calculations.

For EnerGuide: Is used for adjusting SHGC and R-value from the test data. Exported to HOT2000 as height attribute in window dimensions.
