Energy management systems have been developed in order to achieve goal of energy efficiency in the focused areas. Home simulation is one of the tools that can simulate electricity consumption based on the home appliances usage. However, several elements were ignored in traditional home simulation. In this paper, we introduce the home simulation, which can simulate not only the electric power and its consumption, but also the thermal energy consumption. Relationships among five elements are considered in the home simulation. To validate the performance of the proposed home simulation, a real experimental house is used to conduct the experiment. The results showed the ability of the proposed home simulation to simulate the thermal energy and estimate the temperature of various rooms with an error of 1.2 degrees Celsius. Furthermore, the electricity consumption is also simulated based on the human activity schedule and home appliances usage.
