Unglazed Solar Thermal Systems for Building Integration, coupled with District Heating Systems. Conceptual Definition, Cost and Performance Assessment. Journal of Facade Design and Engineering, [S.l.], v. 6, n. 2, june 2018. ISSN 2213-3038. Available at: <https://journals.library.tudelft.nl/index.php/jfde/article/view/2085>. doi: https://doi.org/10.7480/jfde.2018.2.2085.2213-302X,http://hdl.handle.net/11556/557In this paper, the energy performance of a Solar Thermal (ST) façade system is studied for its connection to a District Heating System. This concept allows for the direct use of ST heat in the building, while taking profit from the network for delivery/selling of excess heat and purchase of heat during periods of underproduction. The use of Unglazed Collectors for low-intrusive architectural interaction in façades is discussed. Studies are carried out on the heat production of the system and its capacity to cope with local demands. Economic studies are carried out in order to balance the investment and operational costs/profits of the system.engAttribution-NonCommercial 4.0 Internationalconference output10.7480/jfde.2018.2.2085open accessSolar systemsThermal energyBuilding integrationEnergy systems2213-3038
