The area of domestic horticulture continuously enlarged and the heating costs also increased to about 30 ~ 40% of the total operating expenses. To enhance the profitability of production, it is increasingly important to estimate the energy costs of greenhouses properly. This study aimed to compare the economic feasibility and the greenhouse gas emission of greenhouse energy systems according to heating methods with different fuel types. The annual power consumption was calculated by using TRNSYS, a commercial Building Energy Simulation(BES) tool. First, the model validation was performed using the experimental data obtained from the greenhouse that uses a gas engine drive heat pump. The results were compared with the reference kerosene heating case (CASE 1), which is widely used in domestic greenhouses. The analysis showed that gas heating case (CASE 2) has reduced total energy costs by 20% and greenhouse gas emissions by 10%. Whereas, the exhaust gas from gas engine driven heat pump can be used as a CO₂ source for enhancing photosynthesis. Lastly. the results from the GHP heating case (CASE 3) showed a 46% reduction in total cost and a 63% reduction in greenhouse gas emissions.
