Suntuitive's adaptability means the Solar Heat Gain Coefficient (SHGC) varies between 0.32 and 0.13 depending on the intensity of the sun.
Unlike permanent dark tints, Suntuitive lets the sun in when it's needed and blocks it when it's not, for better insulated buildings.
Suntuitive's dynamic tint adjusts the light transmission depending on the sun's position, mitigating the need for blinds or overhangs.
Suntuitive manages a building’s changing needs for passive solar heat gain and natural daylight to lower heating, air conditioning and artificial lighting loads.
Suntuitive's best feature is the ability to adjust the Visible Light Transmission (VLT) from 54-11% as needed over the day.
Suntuitive completely blocks UV light, for the most superior fade protection.
Dynamic Glass In Action
The below cafe shows how the glass adapts it’s tint according to the position of the sun. In the morning the glass is at its clear state, allowing full natural light. In the afternoon only the window facing the sun is at full tint to block excessive heat gain and in the evening it returns to clear.
Variable light transmission (VLT) and heat gain (SHGC)
Dynamic glazing is able to adjust the Visible Light Transmission (VLT) and Solar Heat Gain Coefficient (SHGC) based on the position and intensity of the sun.
As the sun moves around the building throughout the day, the VLT and SHGC adapt accordingly. When the window receives direct sunlight, it will be at its full tint in order to block accessive heat gain. Then when the sun sets the window will return to its minimally tinted state to allow in more natural light, as illustrated below. A likeminded graph of a regular IGU with a fixed tint would show a straight line signifying a static VLT and SHGC no matter the position or intensity of the sun.
- Available in many glazing configurations and glass colours/types
- Retrofit, replacement and new construction in both commercial and residential applications
- Vertical or sloped glazing, curved or shaped
- Combine with the best Low-E coating in an IGU for unprecedented performance
Typical IGU Assembly
The variable performance of Suntuitive compared to either clear or tinted windows (with fixed performance), makes it ideal for commercial facades, public spaces, western facing windows and skylights, including but not limited to the following:
- Access to natural light is proven to improve productivity and morale
- Improved health and less absenteeism due to less artificial lighting and temperature control
- More hygienic than blinds
- Patients recover quicker with access to natural light
- More practical than blinds
- Patrons more comfortable thanks to less artificial light and temperature control
- Lower energy bills
- Students proven to concentrate better with access natural light
- Less spread of illness due to less artificial temperature control
- Lower energy bills
