Intelligent Daylighting System

Transcription

1 Intelligent Daylighting System In building design, bringing daylight indoors lifts our mood and improves productivity. But too much sun indoors causes glare and overheating. 87% of solar heat is blocked by Controlite panels in the CLOSED position 25% of visible daylight is transmitted through Controlite panels in the OPEN position Light transmission correlates directly to solar heat gain. Managing light transmission and solar heat is critical to effective design and efficient energy use. Traditional skylights and daylighting systems often deliver too much sunlight on hot summer days and fail to take advantage of the natural light during short winter days. The Controlite intelligent daylighting system brings the optimal amount of daylight indoors. Idrotten Hus Gymnasium Helsingborg, Sweden

2 Complete Control The challenge remains: How can we let in the optimal amount of light all year round yet avoid unwanted heat? The Controlite glazing panel is a translucent polycarbonate panel with integrated, rotating louvers ( RotaBlades ). The louvers adjust their position throughout the day to transmit the optimal amount of daylight. The Controlite system allows for complete control of the desired indoor light intensity any time of the day, any time of the year.

By controlling daylight transmission and solar heat gain, Controlite panels allow for larger skylights in commercial and public buildings, maximizing daylight in winter and blocking solar heat in summer. Increased comfort through optimized daylight. The Controlite system adapts to changing light conditions throughout the day for effective control of indoor light, shade, and solar heat gain. Energy-savings. The Controlite system significantly reduces energy use from airconditioning, heating, and artificial lighting. Sustainable design. Controlite panels integrate into energy-efficient building design and allow designers to earn credit points with green building rating systems.

3 Optimizing Daylight Traditional glazing surfaces reflect the low-angle light in the morning, afternoon, and winter. As well, they introduce too much solar radiation at noon, when the angle of incidence is high. The Controlite panel optimizes sunlight by adjusting the position of the RotaBlades to the angle of incidence. Low angle of incidence (morning, afternoon, winter): The Controlite system sets the position of the RotaBlades to transmit the maximum amount of daylight. High angle of incidence (noon): The opaque face of the RotaBlades reflect solar radiation to achieve the perfect balance of light and comfort, reduce heat gain, and save energy costs.

4 How It Works? How It Works The Controlite system presents a dynamic, cost-effective solution for managing and controlling daylight in office buildings, shopping malls, schools, libraries, stadiums, museums, and more. An external sensor detects the direction of the sun; internal sensors register the level of light inside the building. The intelligent system then balances light levels, solar heat, and shade to transmit uniformly diffused light and create a comfortable indoor environment.

5 Why Controlite Our Top 10 Reasons 1. Delivers optimal comfort in changing daylight conditions by maximizing available daylight in winter and reflecting solar heat in summer 2. Enables daylighting solutions with significantly larger surface area, thereby increasing overall daylight in the building 3. Improves well-being of building tenants, visitors, and users for increased productivity and an improved indoor environment 4. Creates ideal natural lighting in classrooms and significantly improves the learning environment Gillette Intermediate School Texas, USA 5. Prevents glare with uniformly diffused light: stadiums are perfectly lit for TV broadcasts, athletes are not affected by looking into direct sunlight 6. Withstands weather and temperature extremes due to durable materials and construction 7. Permits multiple uses of covered spaces by adapting indoor light level 8. Saves energy and reduces heating/cooling costs, reduces electricity usage and costs 9. Reduces capital investment in air-conditioning equipment BMW dealership Vitoria, Spain 10. Integrates into sustainable design, reduces energy consumption and consequent greenhouse gas emissions, and significantly contributes to reducing the building s overall carbon footprint
