Heat Control

The cooling bill arrives through the window

Solar radiation entering through glazing is the largest uncontrolled heat input most buildings have. The air-conditioning does not reduce it; it removes it, at a cost, every hour the sun is on the elevation.

The traditional responses each have a price. Blinds cost the daylight and the view. Fixed dark tint costs the daylight permanently, including on the days it was not needed. Heavier plant costs capital and runs harder.

Intervening at the glass line

Incorporating smart glass or smart film in the windows takes charge of the heat arriving with the sun's rays and keeps the space at a comfortable temperature through the year.

Smart glass and smart film feature electrochromic coatings that react to changes in light, heat and electromagnetic fields, adjusting their tint for insulation and energy efficiency — so the response tracks the condition rather than sitting at a fixed compromise.
