Abstract: For houses and other buildings in remote locations, which are not serviced with mains (municipal) utilities, a module includes the electric generator, water supply, sewage disposal, etc facilities. The module and its utilities are constructed, assembled, and installed into a room-structure, in a factory, whereby the whole module can be tested prior to shipping. The physical and structural integration of the components and systems permits and enhances functional and operational integration of the systems. The module uses co-generation, heat exchangers, etc, for coordinating the hitherto-separate utility systems.
