A new rooftop greenhouse project has been launched in South Korea. The primary objective of the project is to make the standard model of the rooftop greenhouse building which can maximize energy utilization by developing efficient power generation system and exchanging energy between building and greenhouse. The key technologies of the project consist of the following 4 parts; (1) the high efficient distributed power generation (quad-gen) system with low emission, (2) the optimized smart farm solution customized for urban applications, (3) the intelligent energy management system controlling energy consumption in the building and the greenhouse simultaneously, (4) standard design of the rooftop greenhouse building model. Finally, the developed rooftop greenhouse building model will be demonstrated at 2 commercial buildings in Seoul and vicinity. The demonstration buildings will be utilized as a testbed for the developed technologies in this project and a living laboratory to verify the feasibility of urban farming. Through this project, we are trying to validate the positive effects of the urban rooftop greenhouse building from technical, economic, environmental and social perspectives. It will be very important to make the sustainable business model and provide the support measures of the rooftop greenhouse building. The current status and planning of the project will be introduced in the presentation.
