The study analyzes the heating energy performance and water use reduction of the deteriorated single-family house with energy conservation measures (ECMs) such as double-glazing window, internal insulation, high-efficiency boiler, LED lightings, and water-saving closet. The building energy consumption and savings of each energy conservation measure are analyzed using the DesignBuilder program. The payback period and life cycle cost are analyzed to verify the indices of the cost effectiveness. As a result, the refurbishment of the internal insulation system is identified to be the most effective measure to save energy and cost. The simultaneous consideration of thermal insulation and high-efficient boiler helps the low-income bracket among the single-family houses of the old downtown area to increase their residential improvement.
