Abstract. This study shows a two-step method for smooth design of control systems for sustainable homes. First, we select important elements of the standard home on the basis of two factors, material and space, and determine the relationship between these elements and sustainable development. Next, we demonstrate the second step, a sustainability checkup on a home as an object. The results of the sustainability checkup can smoothly identify necessary system components and help to design control laws, which confirms the effectiveness of this method.
