Construction glass

Building with glass is not just
about light; it's also about heat.

Glass has been used as a construction material for more than a thousand years, but it is only in the last few decades that we have seen the proliferation of buildings clad almost entirely in glass.

The properties of glass that allow the visible spectrum of light to pass through also allow heat, in the form of long wave radiation, to pass and re-pass. This is what causes the traditional greenhouse to heat up during the day by virtue of the suns energy, then to lose all of that heat just as quickly during the evening.

Heat loss from construction glass surfaces has been successfully tackled by the use of two and three layer-glazing units, and efforts to reduce heat build-up range from simple window blinds to reflective film coatings. But the truth is, the ambient temperature within these buildings is primarily managed by energy intensive air conditioning and heating units.

Optitune, in conjunction with SERIS (Singapore Energy Research Institute), are developing Optitune's patented polymer coating technology to provide for low cost, high volume production of energy efficient coated glass. Our Low E coating reduces the heat loss from within a building and the Solar C coating transmits light from the visible spectrum, but reflects the suns long wave radiation that causes heat build up.

A managed use of Low E and Solar C coated construction glass enables passive management of a buildings ambient temperature, significantly reducing the costs for secondary heating and cooling.
