System Performance
Thanks to tridimensional direction-selective mirror profiles, Okasolar reflects high-angled sunlight and aims low-angled and diffuse daylight towards the ceiling, bringing it deeper in the room without any moving components. As a fixed system, its predetermined design will condition its optimal application, typically a placement in vertical windows and skylights in temperate climates. The geometry of the louver cross section allows partial transparency dependent on viewing direction (the distance between louvers is 17mm (0.67’)). Its capability to protect from glare can be insufficient in some particular applications. For a more advanced lighting analysis and project specific results, we recommend using the Lightsolve program (under development).

System Description
The Okasolar unit holds a series of fixed aluminum or steel louvers within two panes of glass. The installation and maintenance requirements are the same as for any other glass unit. One requirement to take into consideration is that with a 22-30mm (0.86’-1.18’) cavity (creating a full thickness of 34-50mm (1.39’-1.97’)), the overall unit becomes thicker than average IGUs. The pane can be no wider than 3m (118.12’) and its maximal height is 4m (157.5’). Its maximum surface area is 7sq m (75.35 sq ft). The light performance relies on the louver cross-section design and on its highly reflective coating. In terms of its ecological performance, it is estimated that using Okasolar, electric lighting loads and energy consumption for cooling systems can be reduced by 10-30%. |
