Daylight Guiding Light Shelf System. Kinetic light shelving system that both disperses light and reflects light onto the ceiling as a way to save energy in an office setting. 

Collaborative project with Dalia Ahmed and Dalal Elsheikh.
PRECEDENCE
Architectural light shelves are horizontal surfaces attached to windows above eye level and reflect sunlight deep into a room. Installing these into your home or office will cut lighting costs and conserve energy.
LIGHT SHELF
Overall approach is to disperse the sunlight while also reflecting it as far as possible into an environment. The system will incorporate a reflective surface that will project light onto the ceilings of a space.

MUSCLE WIRE
Daylight shelves are typically a static system. Our project proposes the use of smart materials for the operation of a kinetic light shelf in order to bypass using a motor or electricity or sensor.
A shape memory alloy known as “Muscle Wire” reacts to the air temperature and acts accordingly in order to combat solar heat gain. Muscle wire is connected to the light shelf which contracts as the temperature goes up closing the light shelf. Its rotational motion blocks sunlight and closes at a speed proportional to to the rising temperature.
Noor’s technology makes light shelves available to those living and working in hot climates.

DISPERSION OF LIGHT
No longer will a home owner feel the constant need to repel unwanted sunlight in their eyes or constantly adjust blinds due to solar heat gain.
The system changes by itself daily due to the shape memory alloy and is also manually adjustable for the seasons. It fits into office windows which can help bring a uniform sense of a day lit environment for as long as possible before it is necessary to turn on artificial lighting.
Most light shelves are stationary even though the sun is constantly moving. Then there are blinds and systems which disperse and shade from daylight.  Our project is the bridge between these different systems which moves depending on room temperature.
