From Colt International in the U.K., the non-electric Girasol drive system for controllable shading louvers is powered only by the heat of the sun to achieve appropriate shading based on current solar conditions. Designed to install on any external controllable fin system, each noiseless, thermo-hydraulic Girasol drive can control over 500 square feet of louvers. The units’ slow movement prevents optical irritation from rapidly changing light levels....
Solarfin, from Colt International in the United Kingdom, is a controllable fin shading system that installs horizontally or vertically on a building’s facade. The louvers follow the sun’s path—they can pivot 120 degrees—optimizing daylighting, minimizing heat gain, and overcoming the potential for too much or too little shading that comes with fixed systems.
The low-profile LightLouver Daylighting System combines daylighting and solar control by using highly reflective fixed louvers to redirect incoming sunlight from any angle onto a room’s ceiling, providing uniform ambient light. Installed like lightshelves (above the vision glass on tall windows), a one-foot-tall section will reflect daylight about 14 feet into a room.
