NET-ZERO ENERGY BUILDING AND NET-ZERO ENERGY MANAGEMENT METHOD FOR BUILDING

摘要

PROBLEM TO BE SOLVED: To provide a method capable of reducing an annual primary energy consumption to net zero.;SOLUTION: There is provided a net-zero energy building 10A including: a structure 10 which has electric facilities 10E; and an electric power supply system which supplies electric power to the electric facilities. The electric power supply system includes an energy conversion device 12 including a power cycle 15 having a compressor 27, an electric power gas generator 42, and a movable piston 200. The energy conversion device heats the electric power gas generator to a predetermined temperature with pulse electric power of a power storage unit 20, generates a high-pressure working fluid by compressing a working fluid by the compressor, generates a high-temperature high-pressure power gas by bringing the high-pressure working fluid into contact with the electric power gas generator, generates mechanical energy by operating the movable piston with the high-temperature high-pressure power gas, and generates electric power by supplying the mechanical energy to an electric power generator 16.;COPYRIGHT: (C)2015,JPO&INPIT
