NOVELTY - The collector has a black sealing membrane made of polypropylene resisting to ultraviolet rays and absorbing thermal energy provided by the solar radiation in a roof surface for restoring the thermal energy by conduction and radiation at heat conducting pipes(2). The pipes containing circulating and transferring or refrigerating fluid are inserted in an upper part of a roof isolating panel made of foam glass, where the panel transports the accumulated heat towards an energy distribution and exploitation device.    USE - Architectural solar heat collector for use in an energy cogeneration system (claimed) for being fixed in a roof and a terrace of an individual or collective building for producing thermal or electrical energy. Uses includes but are not limited to industry, military, agricultural or tertiary, teaching purpose, sports or medical, sealing and insulating industries and electric and environment engineering.    ADVANTAGE - The collector has the function of energy production, and is compatible with the temporary function of retention and regulation of rain water collected by surfaces of the roofs, thus facilitating the defrosting and snow removing by temperature inversion of the collectors. The collector improves the environmental protection, architectural qualities and techniques of the envelope of the buildings. The collector provides the function of utilization and recycling of nonpolluting renewable energies, controlling of rain water, durability and recyclability of used materials, landscape integration, easy maintenance, inexpensive and rehabilitation of the buildings.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for defrosting and snow removing of a surface of a sealing membrane.
