5.1.2 Solar Exposure Analysis

This calculation uses SunCast’s generated hourly solar shading data to produce the exposure results in hours and percentage of available hours for the specified period.
Calculation (for each external surface):
1.     Summate the hourly percentage area values.    (% area) => Hours
2.     Optionally then convert the value to % available.    (Hours ÷ Available Hours) × 100
See Section 5.1.3: Methodology Notes for more information.
