Abstract: Nowadays, global warming caused by greenhouse gases, is a serious problem worldwide. IPCC (Intergovernmental Panel on Climate Change) suggested preparation plan such as emission factor of greenhouse gases and equation of emission in 1996. Horticulture facilities are taking the biggest blow due to the increasing heating bills as they mostly use fossil fuel but in turn they are generating huge amounts of greenhouse gases. Therefore, this paper accurately quantifies the amount of electricity consumed by fan coil unit using various heat sources in largescale horticulture facilities based on IPPC data. Also analysis of economic feasibility accomplishment, efficiency and gas consumption in gas boiler, which is commonly used in large-scale horticulture facilities, is done. Calculation of heating bills in each case has been done based on recent gas and electricity prices in Korea to find the economic feasibility for setting up of heat pump system. The most economic and environment-friendly heating system to be used in the large-scale greenhouses is suggested in this study.
