Abstract

Purpose: This study was on the economic feasibility of BIPV system, focused on comparison with construction cost of BAPV system depend on roof finishing materials, and to suggest basic data on the construction cost. Method: Construction cost of BAPV system was calculated, by selecting asphalt single, flat type roof tile, color steel plate, titanium zinc plate as roof finishing material of residential building and by sum up each cost for roof finishing construction and cost for 3kWp-volumed PV module installation. Also, the economic feasibility was analysed quantitatively by comparing the cost for BIPV system construction, installing same volumed PV module instead of roof finishing materials. Result: 1. By installing BIPV system instead of the roof finishing material, the cost of construction falls ; about 19% in case of the titanium zinc plate, which is the most expensive, and about 11% in case of the color steel plate. 2. Reducing amount of the construction cost gets larger because of installing BIPV module instead of the roof finishing material, as the construction cost for roof finishing material gets higher ; therefore, it is more economical than BAPV system in terms of whole cost of construction.
