Design and transient analysis of renewable energy-based residential net-zero energy buildings with energy storage

In this research, by the installation of solar collectors and photovoltaic panels, a building with almost zero energy emissions is designed in TRNSYS software, and with a parameter study on a residential building located in a typical city, the optimal design conditions to provide suitable conditions for thermal comfort, and the electrical power required by the building is suggested. Also, to improve the investigated system, in addition to the two-dimensional design, the three-dimensional design of the building is examined. After the design of the building, it is observed that Bushehr is suitable for designing a building with almost zero energy emissions through the installation of solar collectors and photovoltaic panels due to having the appropriate intensity of sunlight. Also, due to the suitable radiation conditions, it is suitable to use a battery to store electrical energy, and also because the cooling load required to provide thermal comfort in the summer season is high, therefore, the use of a diesel engine is suitable for use in emergency situations. Among the different fuels for starting a diesel engine, diesel fuel has the lowest consumption, and hydrogen fuel has the highest consumption.
