One approach to increase energy efficiency and energy flexibility of production systems is to connect independent production systems and local supply systems to energy networks. One technology that can be adopted is smart rooftop greenhouses (SRG). The main subject matter of a SRG is the energy symbioses through waste heat usage and smart grid integration to improve energy efficiency of a production system. With a SRG on a factory the waste heat and CO2-emissions can be used for plant production. As a SRG can be heated with low temperature waste heat, a big energy efficiency potential in the German industry can be addressed. Furthermore, this allows for space to be used more efficiently for supporting land-use reduction goals. The connection and integration of a SRG in the industrial smart grid brings in further flexibility for its energy optimal control. With a highly automated and digitalized plant production technology in a controlled environment agricultural system like an SRG, the production of bio-based production materials or food can be automated and optimized. The aim of this publication is to present a concept for smart rooftop greenhouses. Therefore the paper is supported through a systematic literature review on the subject. The results of this review have been combined and further developed with new approaches.
