SRT glass is a type of dynamic glass with a thermochromic PVB interlayer which harnesses the sun’s rays to alter the light transmission properties based on the amount of direct sunlight hitting the external surface.
That is, it self-tints as necessary to block excessive heat from entering a building when the sun is at its hottest and highest position in the sky and returns to its natural state in the absence of direct sun light - so the amount of daylight is as it should be at all times.
SRT's ability to adapt is reported to result in a 20-43% annual energy bill savings, with a 15% reduction in air-conditioning loads at peak demand times. Not to mention occupant comfort and health benefits from being able to block the negative aspects of the sun without compromising visibility and natural light – resulting in increased productivity and other intangible savings.
To achieve similar thermal comfort and block the sun would otherwise require blinds, overhangs and permanent dark tints which not only add to costs but compromise natural light and the view. Hence why SRT glass is a glass for people, it promotes health and well-being of occupants by providing them with a connection to the outdoors, natural light and blocking the harshness of the sun as necessary.
While low-e glass has become norm with rapid advancements in this technology, what isn't as well understood is how much better a low-e IGU performs when combined with SRT technology and could be why it is not as diffused in the Australian market as others. But with increased legislation and demand for energy efficiency we must innovate and evolve - and SRT glass is already leaps and bounds ahead.
This Whitepaper explains exactly how SRT technology works with low-e glass, dispels some common misconception and explores the vast cost and health benefits of specifying it - which extend beyond the obvious energy performance.
