Recently, building energy simulation technique to simulate a model similar to the actual conditions through a variety of dynamic simulation methods, and predict and analyze the flow of energy is being actively introduced and developed. As a fundamental research to apply the BES technique which is mainly used for analysis of general buildings, to a greenhouse, this research designed Venlo type greenhouse using one of the commercial programs, TRNSYS. And field experiments were carried out in multi-span plastic-film greenhouse in Paju. The internal temperature of greenhouse was compared to validate the greenhouse energy model. The temperature of the greenhouse was maintained using an air source heat pump and the effect of the plant growth on the internal thermal environment was considered. The effects on latent heat cooling were calculated by estimating the plants evapotranspiration by Penman-Monteith model. With the aim of developing a model-based method to design greenhouse for a broad range energy supply system and economic condition, we build a model for energy supply system analysis.
