Height of the opening in meters.
Used to calculate the area of the opening via height × width. This area is used in heat loss and solar gain calculations.
R-value of the opening (thermal resistance) in metric.
Represents the thermal resistance of the opening. Higher values indicate better insulation. Used in conductive heat loss calculations. Typical values range from 0.2-0.6 (single pane) to 1-1.7 (high-performance).
Solar Heat Gain Coefficient of the opening.
Represents the fraction of solar radiation admitted through the opening. Used in solar gain calculations, particularly for cooling load analysis. Values typically range from 0.2 (very reflective) to 0.8 (very transmissive).
Width of the opening in meters.
Used to calculate the area of the opening via height × width. This area is used in heat loss and solar gain calculations.
Represents an opening (window or door) in a building component. Used for abstract representation of fenestration.
