The specific parts of the design strategies for Nature Between, including architectural concept, materials, passive strategies and active strategies, are introduced and analyzed. This paper presents the design strategies and energy performance of a net-zero energy house (NZEH), Nature Between, which was designed and built to participate in the Solar Decathlon China 2018 competition. However, irrespective of the software used in the system design, the energy generated for the isolated system is more than the energy demand of the house thus leaving excess electricity that can be sold to the grid system. Further analysis indicates that it more economical to design the hybrid power system in iHOGA software. For the iHOGA software, 85.7% (8,188.6kWh/yr) of the total annual energy is produced by the wind turbine and 14.3% (1,361.6kWh/yr) is produced by the solar cells. Analysis reveals that for Homer Pro software, 95.8% (52,566kWh/yr) of the total annual energy is produced by the wind turbine and 4.2% (2,308kWh/yr) is produced by the solar cells. The hybrid power system to meet this energy demand is designed and simulated using both Homer (Hybrid Optimization of Multiple Electric Renewables) Pro software and iHOGA (improved hybrid optimization genetic algorithm) software. House located in Newfoundland is designed using the Energy 3D software and the annual energy (kWh) demand for the house is determined. In this paper, a hybrid power system is designed for a house in St.
