Build-in Transparent Collector Construction

There are several ways to utilize renewable energy sources. Collectors are well known as one of the oldest build-in or post-mount construction at buildings. This paper presents idea of transparent sun collector based on insulation glass unit, with inner and outer liquid circulation. The heat absorbed from the sun in inner circuit liquid is transferred and transmitted by heat exchanger to the secondary circuit. Where energy can be stored or used in preheating devices in hot water delivery systems. This system can be applied in buildings with huge transparent or non-transparent glass based facades with suitable needs for hot water for example in administrative buildings, swimming pools, gyms etc. Research at current state deals with mechanical construction of window and prepares laboratory tests and build in measurements of construction itself.
