Performance assessment of heated windows in a real-life setting
Bison code: L.28300
Windows in buildings are important for the creation of a pleasant work and life environment indoors. Windows allow sunlight to penetrate into the building and provide, as transparent facade elements, a view to the outside. Whilst those window functions are key to our well-being indoors, they also have specific disadvantages when compared to opaque facade elements, such as walls. They are typically characterized by a lesser insulation value than walls. A reduced insulation value results in lower surface temperatures, which can cause (down)draught and radiative discomfort. To reduce the effect, Pilkington, a world leading as glass manufacturer, developed a glazing type with integrated heating elements to off-set the reduced surface temperatures. Pilkington claims that heated glass as smart heat-dissipation element has the potential to increase a buildings sustainability index. In this project, you are given the chance to conduct experiments with heated glass in Saxion’s Smart TinyLab, where one of two test rooms is equipped with a window containing heated glass. The aim is to determine whether heated glass indeed increases the energy efficiency and thermal comfort in living spaces. You will look at how much of the electric energy necessary to heat the glass contributes to heating the living space and to what extent the heated glass improves the thermal comfort indoors?
