| summary |
Daylight is an important factor in interior design. The benefits can be seen in reduced need for heating and artificial lighting, while the caveats are visual hindrance, glare, thermal discomfort and increased energy for cooling. The industry standard way of controlling daylighting is with roller blinds, venetian blinds, curtains, static and automated façades which do not allow sufficient control over daylight. The aim of this paper is to explore the potential of using circular modules with the iris diaphragm mechanism as a system for controlling the daylight amount, similar to the approach used on Arab World Institute. Circular module that are proposed in the paper consists of an outer casing, inner rotational and stationary rings and blades. A parametric iris model is generated and optimized to conform to the criteria of having the smallest casing, thinnest blades and the least amount of blades to decrease fabrication and assembly time. The circular module is applied in three layouts on a rectangular opening to calculate the efficiency in daylighting control. Obtained results show significant increase in systems flexibility and performance compared to the closest implementation in the south façade of the Arab World Institute. |
