Sundance uses astronomical equations to determine solar data

Sundance uses astronomical equations to determine solar data for any time and location. The Solar Heat Gain Coefficient/Radiant Time Series method is used to calculate solar cooling loads through windows, allowing Analysis of the effects of shading by overhangs, external louvres and adjacent buildings. All irradiance calculations are performed in accordance with UK and US calculation methods. Locations and glazing databases may be edited and added to. Sundance operates in metric SI and imperial IP units.
