3.2.4 Sunlight Hours Analysis
Sunlight hour analysis calculates the number of hours of direct solar exposure received by input geometry using sun vectors from the Sun Path component. This component can be used to evaluate the number of hours of sunlight received by vegetation in a park or the hours where direct sunlight might make a certain outdoor space comfortable or uncomfortable. For the purpose of this exercise it is strongly suggested to use tools like ladybug available in grasshopper as a plug in to have a parametric control. Ladybug imports standard Energy Plus weather files (.EWP) into Grasshopper and provides variety of 3D interactive graphics to aid the design-making process during initial stages of design. The weather data used for the purpose of this study are approved source by the World Meteorological Intergovernmental Organization. It takes inputs like north, geometry, context grid size, orientation, time giving larger parameter control over the final output that is color chart of number of sunlight hours.
