<p>Due to energy shortage and environmental protection, reduction of energy consumption and CO₂ emissions has been demanded. A smart home system is now expected as one of the solutions to satisfy these demands by using various home-energy devices such as cogeneration system, electric vehicle, and stationary battery in cooperation with each other. This paper analyzes the time-series dataset of the optimized home-energy device control, which minimize energy cost including initial investment and CO₂ emission on a sunny winter day, by the proper orthogonal decomposition (POD). POD extracts specific rules that discharging a stationary battery in the daytime with higher power unit price and operating a cogeneration system in the time when electricity and heat demands exist are significant for energy cost reduction. Thus, POD helps to consider universal rules which will be effective anytime for home energy management.</p>
