The Daylighting Dilemmas & Solutions


Intelasun Daylighting Control

 

The Daylighting Dilemma:

How do you receive the exact daylighting you want—no more, no less?


How do you avoid unwanted solar heat gain?


How do you control daylighting glare?

 


The Problem:

  • Sunlight transmits solar heat and glare through the glazing.
  • Solar heat inside the space is generally correlated to light transmission, Solar Heat Gain Coefficient (SHGC) values, and the size of the glazing area in relation to the space.
  • Many traditional PASSIVE skylight designs are compromises—resulting in failure to maximize daylighting benefits.
  • PASSIVE skylight designs deliver too much solar heat on hot sunny days and during peak sunlight hours or too little light on dark gloomy days.
  • PASSIVE skylight designs provide no control over glare, sun‐shading, and high energy costs

The Solution:


IntelaSun® ‐ Controlled daylighting deliver the exact daylight amount you want – no more, no less. Intelligent SolaBlades® within the glazing panels gauge the sun’s position in the sky, and then dynamically manage the desired sunlight, solar heat, and sun‐shading inside the space. IntelaSun® ‐ Controlled Daylighting Systems provide more daylight in the winter, morning, late afternoon and on dark gloomy days, and less daylight in the summer and peak sunlight hours.

The SolaBlades® can be set to deliver direct or diffused sunlight. By angling the sunlight that penetrates the space, the SolaBlades® make use of the physical fact that light hitting at an angle delivers less energy per square foot than direct sunlight. A sun-tracking sensor also allows alignment of the SolaBlades® to an optimal position in relation to the sun’s position in the sky, to harvest daylight that would otherwise be lost due to the low incident angle of the sun early and late in the day.
