2. TIME: 2:00-4:00pm 36˚ C ±2˚ Outdoor temperature 40 ˚ C ±2˚ Room temperature 37 ˚ C ±2˚ Glass temperature Wind can’t help much to cool down the temperature indoor Solar energy is absorbed by indoor furniture, making them become a heat source or hot spot. These hotspots re-radiate far infra-red (heat) back into the room, increasing the room’s temperature (like a heater).

3. Direct solar energy (sun rays) exposure causes discomfort to tenants / patrons. Building operator have to lower air conditioner temperature for better comfort. As a result: High electricity consumption from increased air- conditioner’s loading Imbalanced room temperature – people in areas without direct exposure to the Sun may feel cold.

4. TIME: After Sunset Re-radiation 36˚ C ±2˚ Outdoor temperature 40 ˚ C ±2˚ Room temperature 37 ˚ C ±2˚ Glass temperature Wind can’t help much to cool down the indoor temperature After the sun sets, the hotspots continue to re-radiate heat that had built up during the day. It takes hours for the furniture to cool down as it releases heat at a slow rate.

5. As a result: The combination of hotspots releasing heat at the same time further impedes the cooling down process.

TIME: 2:00-4:00pm With KristalBond, majority of solar energy is stopped at the glass, instead of allowing it into the indoor. As a result, much less hot spots creased compare to non coated glass. There is no need to lower the air conditioner temperature as ALL tenants /patrons are comfortable regardless of their location, since much less direct solar energy exposure. 34 ˚ C ±2˚ Room temperature

8. As a result: Reduced electricity consumption from low air- conditioner loading. Uniformed air temperature indoor, bringing better comfort level to ALL occupants.

9. TIME: Sunset 2% Re-radiation6% Re-radiation Glass temperature 36˚ C ±2˚ Outdoor temperature 34 ˚ C ±2˚ Room temperature 49 ˚ C ±2˚ Glass temperature Wind carries energy from glass surface outdoor, cooling it down faster. With KristalBond, more solar energy is absorbed by the glass, not by the furniture indoor. The glass surface is exposed to the exterior where wind accelerates the release of the absorbed heat as much as 3 times* more than the interior surface (*according to ISO9050.)

10. As a result: Once the Sun no longer shines directly against the glass panel (depends on each building’s orientation), the air conditioner consumes less electricity to regulate the temperature, since there is less heat source or hotspots.
