Unglazed Solar Thermal Systems for Building Integration, coupled with District Heating Systems

In this paper, the energy performance of a solar thermal (ST) façade system is studied in relation to its connection to a district heating system.

Illustration :

The connection of a solar thermal (ST) façade system to a district heating system 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.

In this paper, presented at the ICAE conference in Donostia-San Sebastian, the energy performance of a solar thermal (ST) façade system is studied in relation to its connection to a district heating system.
