The purpose of this paper is to suggest the calculate method of photovoltaic system government subsidies using the benefit-cost analysis. Perspectives of benefit-cost analysis for photovoltaic system government subsidies is participant, non-participant, administrator and nation. This study identifies the benefit and cost components and benefit-cost calculation procedures of photovoltaic system from four major perspectives : participant, non-participant, administrator and nation. The results of each perspective is expressed in the net present value. The results of case study of the photovoltaic system government subsidies was calculated to be 3,974,000won. Case studies following results were obtained: participant(net present value of 8,024,000won, benefit-cost ratio of 1.5, simple payback period of 5.75years), non-participant(net present value of 0won, benefit-cost ratio of 1.0), administrator(net present value of ? 14,290,000won, benefit-cost ratio of 0.22)and nation(net present value of 1,791,000won, benefit-cost ratio of 1.08).

The social concern with maximum power demand by heating and cooling systems has been growing for the last several years. In particular, large-scale power outage occurred in September 2011. The purpose of this study is compare of maximum power demand in building's heating and cooling systems. The results of this study are as follows; 1) Maximum power demand per 1usrt of electric heat pump system is the summer 1.248kw, winter 1.335kw. maximum power demand per 1usrt of gas engine driven heat pump system is the summer 0.1398kw, winter 0.1329kw. maximum power demand per 1usrt of absorption chiller-heater + constant air volume system is the summer 0.5996kw, winter 0.4590kw. 2) The result of maximum power demand per 1usrt of building's heating and cooling system, the order of viewpoint of maximum power demand was gas engine driven heat pump system, absorption chiller-heater + constant air volume system and electric heat pump system.

The purpose of this study is suggest method to reduce economical greenhouse gas emissions of existing building for expansion in green building. Economical greenhouse gas emissions reduction methods presents economical greenhouse gas emissions reduction comparable index. Economical greenhouse gas emissions reduction comparable index was applied to the concept of cost effectiveness. Economical greenhouse gas emissions reduction comparable index were used life cycle cost and TCO2. Life cycle cost(LCC) is the process of making an economic assessment of an item, area, system, or facility by considering all significant costs of ownership over an economic life, expressed in terms of equivalent costs. The essence of life cycle costing is the analysis of equivalent costs of various alternative proposals. The results of this study are as follows; 1) Economical greenhouse gas emission reduction comparable index are proposed of existing building for expansion in green building. 2) In the economical greenhouse gas emissions reduction methods of renew, the order of the economical greenhouse gas emissions reduction shows gas engine driven heat pump, electric heat pump, light emitting diode lighting, solar energy generating facilities, geothermal system, central heating system(urban gas) + unit cooling system(electricity) and central heating system(diesel) + unit cooling system(electricity).

The purpose of this study is to suggest the calculation of economic analysis method in heating, ventilation and air-conditioning system. Since the evaluation of economical efficiency of heating, ventilation and air-conditioning system has been changed according to the selecting of the evaluation method. Economic analysis method of heating, ventilation and air-conditioning system exist initial cost method, pay back period method and life cycle cost analysis. The results of this study are as follows; (1) This study propose the calculation of economic analysis method for initial cost method, pay back period method and life cycle cost analysis(present-worth method) in heating, ventilation and air-conditioning system. (2) The calculation of economic analysis method in heating, ventilation and air-conditioning system come into use economic evaluation method.
