Abstract: Establishes an economic benefit evaluation model of the solar water heating systems in the perspective of the whole life cycle of building, which comprehensively considers the factors of the equipment installation and update, rising energy prices, the changes in the collector rate and pipeline loss rate, the costs in the process of repairs, cleaning, insulation, operating expenses, the replacement of equipment salvage value, the cost of removing, and so on, then uses the empirical analysis to verify it. The conclusions show that the solar water heating systems during the whole life cycle of buildings is economically feasible.

Key words: solar water heating system; the whole life cycle of building; economic benefit evaluation
