3.2.5 Daylight analysis

Daylight factor calculation are a recognized method for evaluating the light levels inside different rooms of a building block annually or a specific concerned time frame. Although this study is similar to sunlight hours it is recommended for interior spaces as it considers reflectivity from complex surfaces, understands material giving accurate results.

For the purpose of this exercise it is strongly suggest 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 this study are approved source by the World Meteorological Intergovernmental Organization.

It takes inputs like north, geometry, context grid size, orientation, time give larger parameter control over the final output that is color chart of number of sunlight hours.
