The Presence of building energy simulation tools for energy analysis of different buildings, allows greater opportunity towards energy management and saving ( Fitz-Rodriguez et al., 2010). Investigators are doing research by making experiments, numerical simulations and using different computer programs for greenhouse energy management analysis ( Kolokotsa et al., 2010). Analysis of energy management techniques in real greenhouses by experiments will no doubt provide the most reliable data the results obtained from such tests are site-specific and so are only valid for that particular greenhouse and its local climatic conditions. These energy management techniques are under consideration of researchers and they are working on analysis of these technologies for greenhouse energy management ( Sethi et al., 2013). Various energy saving measures are being used to reduce heating cost of the greenhouse ( Arinze et al., 1986) like use of thermal insulation, solar energy, earth to air heat exchanger, geothermal energy and different heat storage systems.
In the modern greenhouse heating cost of the greenhouse reached 49.5% of the total production cost ( Yang et al., 2012). In all over the world many technologies have been developed for cooling and heating of greenhouses to maintain the optimum inside greenhouse temperature ( Xamán et al., 2014). Due to higher energy demand for greenhouse heating, and continuously increasing price of the fossil fuel, there is much interest to develop efficient technologies to save energy. Likewise, agriculture energy management of greenhouse is one of the most important aspects of the greenhouse farming is to be considered. This review paper provides aid to greenhouse researcher and energy planner for the future studies of greenhouses energy planning.ĭuring recent years as demand of energy is increased, researchers attracts towards energy production, consumptions, storage, management and saving ( Carlini et al., 2010). In conclusion, this paper provides information that TRNSYS have great potential for agricultural buildings energy simulation along with the renewable energy resources and energy saving techniques.
At the end of the paper we draw some important concluding remarks on the basis of reviewing all the investigators contributions for the developments of simulation model of agricultural greenhouse energy management, using a building energy simulation software specifically TRNSYS.
We identified main features of the building energy simulation software, that enable users, to simulate hybrid agricultural building projects by using user defined parameters. We describe different models to understand the behavior of the energy saving technologies with respect to the resources available and different outside climatic conditions. The objectives of conducting this study were, to describe the various energy systems and techniques used for the greenhouse energy management and efficiency analysis of these technologies by using building energy simulation. This paper attempts to present a review about simulation of different greenhouse parameters and energy supplying techniques by using building energy simulation, to find out the optimal solution for keeping greenhouse microclimate favorable for the crop production.
