interrelation <strong>of</strong> shading and daylighting. These two<br />
vital functions have proven to be contradictory in<br />
the mentioned case, where the study <strong>of</strong> an existing<br />
building is concerned. However, shading and<br />
daylighting can be totally combined, when both are<br />
examined at the early stage <strong>of</strong> the building design.<br />
In such cases, the designer should take into account<br />
the various functions <strong>of</strong> the transparent elements<br />
during the decision upon the envelope and the<br />
geometry <strong>of</strong> the building, with regards to its use,<br />
geographical location and user’s needs.<br />
Furthermore, the ongoing study and development<br />
<strong>of</strong> advanced strategies, which act both as solar<br />
control and daylighting intensifiers, resolve the<br />
barriers identified above and promote the design <strong>of</strong><br />
sustainable buildings.<br />
The introduction <strong>of</strong> innovative, advanced<br />
daylighting strategies and systems can considerably<br />
reduce a building’s electricity consumption and<br />
also significantly improve the quality <strong>of</strong> light in an<br />
indoor environment. Such strategies either rely<br />
primarily on admitting diffuse skylight and<br />
rejecting direct sunlight, or use primarily direct<br />
sunlight, sending it onto the ceiling or to locations<br />
above eye height. Main representatives <strong>of</strong><br />
advanced systems that combine shading and<br />
daylighting are the prismatic and laser-cut panels,<br />
anidolic openings, light shelves and reflective<br />
blinds or louvers.<br />
