7. How does it work??

8. Direct Gain
Indirect Gain Day
lighting

9. Direct Gain

12. Radiant panels are simple passive solar systems that are
inexpensive and well suited as retrofits to metal buildings.

14. In summer

15.  In winter

18.  When designing energy-efficient buildings, it’s necessary to know
the solar heat gain of materials used on the structure’s exterior
 Glass and plastic blocks
 Patterned glazing
 Skylights
 Sunshades
 Roof structures
 Tubular daylighting devices
 Solar screens
 Electrochromic and photochromic glazings
 Translucent or solar-absorbent product.

23. Blocks ultraviolet
energy:
 Blocks up to 99.9% of the UV radiation compared to
clear glass unit.
 Prevents fading of interior fabrics and décor.

24. Cooler and comfortable in summer:

25. Warmer in winter:
