Design, modeling and simulation of a green building energy system

Traditional buildings consume more of the energy resources than necessary and generate a variety of emissions and waste. The solution to overcoming these problems will be to build them green and smart. One of the significant components in the concept of smart green buildings is using renewable energy. Solar energy and wind energy are intermittent sources of energy, so these sources have to be combined with other sources of energy or storage devices. While batteries and/or supercapacitors are an ideal choice for short-term energy storage, regenerative hydrogen-oxygen fuel cells are a promising candidate for long-term energy storage. This paper is to design and test a green building energy system that consists of renewable energy, energy storage, and energy management. The paper presents the architecture of the proposed green building energy system and a simulation model that allows for the study of advanced control strategies for the green building energy system. An example green building energy system is tested and simulation results show that the variety of energy source and storage devices can be managed very well.
