Towards novel glazing with seasonal dynamics based on micro compound parabolic concentrators

Thermal loss and overheating caused by glazing is a key issue in reducing CO2 emission and energy consumption of buildings. A novel glazing based on micro compound parabolic concentrators (CPCs) is proposed. The glazing consists of a polymer layer with embedded micro CPCs, which is attached to a glass pane of glazing. Thanks to the geometry and the micrometric size of the embedded CPCs, the proposed novel glazing can reduce energy consumption in cooling, improve visual comfort and maintain clear view through glazing. In the present work, the potential benefits of such glazing are preliminary estimated for Dubai. The seasonal dynamics are investigated by analyzing the direct solar transmittance for the working hours on the spring equinox and the winter solstice. The improvement of visual comfort is studied based on the assessment of glare. First samples with micro CPCs are fabricated, and the high transparency is achieved. The optical characterization using goniophotometer confirms the seasonal dynamics of the novel glazing.
