Solar cooling and more for a large office building

The project started when the SOLID CEO met CGD’ facility manager at a conference and expressed his desire for a green solution as CGD had high cooling, heating and hot water demand.

Together with Energia de Portugal, charged by CGD, SOLID develop a solution for cooling, space heating and hot water with collectors only in the inside of the building complex. The architect refused, that collectors are placed on the visible outside part of the building complex. Even though the building was already existing, the architect has a life-long veto right regarding major changes of the building.

The solar system has a good marketing effect for the bank and boosts its green image. There is even a demo collector in the lobby of the building.
