Objective
Develop and demonstrate technical feasibility of dichromatic gelatine hologram technology for daylight in buildings.
Daylight techniques are used to bring daylight deeper into buildings. In this way artificial lighting is avoided and cooling requirements reduced; this can lead to large energy savings. Presently used techniques such as light shelves, reflective blinds and prismatic tools however are expensive (500 to 1500 ECU/m2). The field of hologram technology is therefore explored as a way to exploit daylight at a considerably lower cost (50 ECU/m2).
The principle of this technology is that windows are coated with a transparent coating in which an invisible diffraction pattern is "printed" by a holographic technique. The window can now deflect transmitted direct and diffuse solar radiation over a well defined angle (which is defined by the diffraction grid characteristics) deep into the building. Similar grids can also be used to reflect away solar light which impinges on the window from well defined angles.
The work programme of this project is as follows:
Establishment of specifications of an ideal holographic film to be used in facade windows in office buildings.
Design and construction of two single layer hologram prototypes.
Design and construction of two multi-layer hologram prototypes (single layers will deflect different colours in white light by slightly different angles resulting in a spectrum of colours in the room; multi-layers compensate this effect).
Evaluation of photometric properties of holographic films.
Test on scale models in office rooms.
Recommendations for improvement of the technology.
