prismatic glazing PVT collectors
▪ reduction of heat gain compared
to conventional triple glazing
▪ winter: 2- 8 %
▪ summer: 39 to 46 %
▪ savings potential
▪ 22 % cooling energy (compared
to clear triple glazing)
▪ 25 % heating energy (compared
to solar protection triple glazing)
▪ increase in production from same
envelope area compared to
combination of conventional
technologies
▪ heat : 35 %
▪ electricity: 39 %
8/10
▪ increasing interest in multifunctional facades
▪ price as a main barrier
▪ prismatic glazings
▪ natural diffuse lighting without sharp shadows
▪ passive solar protection without moving elements
▪ potential for savings compared to conventional glazings (heating, cooling)
▪ glazed PVT collectors
▪ combined heat and power from same area
▪ 5-40 % higher energy gain
