The studio offered the learning for various aspects of Artificial Lighting and Daylight in a space. Various luminaries and their properties were studied to understand their behaviour for distributing light. Simulations were performed to design a optimum lighting design to achieve required lux level in a space. Hands on measurement helped to understand the characteristic of daylight in a space. Sunpath analysis helped to derive a shading design for various time of the year and for different places. Simulations (using DaySIM and Radiance) was used to analyse daylight distribution into a space.

Lux level in a space was measure with hand held instruments, at task level and luminance level of various surfaces was documented to understand the characteristic of light in a space.

Using DIALux Evo, a classroom with different light fixtures was simulated to achieve uniform distribution on the work-plane.

An experimental set up was done to understand the spectral distribution of a fixture, with help of hand held measurements.

With sun-path analysis for Ahmedabad, Horizontal & Vertical Shading Angle was determined for south direction to achieve shading throughout the year

HSA and VSA were transformed into a 3D model to design shading elements for South and West facade, to provide shading all round the year.

Window to floor ratio, spacing of windows, size of windows, and glass VLT are found to be the important parameters for achieving uniform distribution.

Daylight analysis was done for a space for different period of the year (21st Dec & 21st Sep) using Radiance. Evaluation of distribution was done for different configuration of windows.

Using simulation in DaySIM, UDI and cDA for a room and with different window configuration was analysed. various shading elements were used to provide shading throughout the year and also achieve maximum penetration of daylight int the space.

Comparison of various shading and window combinations were performed to achieve at best solution for harness daylight and provide even distribution inside the room.
