Abstract: A modular element for a façade of a building may include: an air conditioning unit; and a channeling system. The channeling system may be configured to receive fluid from an external source. The channeling system may include at least one first channel entering the air conditioning unit. The external fluid source may include a pump configured to circulate the fluid inside the channeling system. The channeling system further may include one or more inlets configured to connect to the pump so as to receive the fluid from the external source and input the fluid into the at least one first channel of the channeling system. The channeling system further may include at least one second channel configured to connect to an internal diffusion element of the building. The at least one second channel may be configured to transport the fluid from the external source to the internal diffusion element.
