Systems and methods utilize a cogeneration system for providing heating, cooling, and/or electricity to an enclosure. The system includes a heat engine for heating and supplying electricity to the enclosure. Coupled to the heat engine is a first conduit configured to transfer fluid from the heat engine to the enclosure to transfer thermal energy from the fluid to the enclosure. The system further includes a heat pump configured to supply at least heating and cooling to the enclosure. Coupled to the heat pump is at least a second conduit. The second conduit is configured to move fluid from the heat pump to the enclosure to transfer thermal energy from the fluid to the enclosure.
