he national target in Denmark is, to supply all the energy demand from renewable sources by 2050. In this thesis, proposal for 100% renewable based energy system in form of an energy symbiosis in Varpelev – Hårlev area, located in Stevns municipality, in Denmark is presented. In order to understand the proposal and also contribute more detail to current phase of Varpelev – Hårlev project, four phases of work have been considered for development of renewable energy project, which are 1. Proposal development, 2.transition phase 3.project development 4. Physical implementation. The four phases are inspired from some of the RUC research group works with ongoing renewable energy projects in the municipalities in region Zealand. Series of steps1 and requirements are defined as the detail element of these four phases which are developed by applying four approaches which are Integrated design approach, Backcasting approach, logical framework approach and system approach. The work in this project is on the first two phases, and the two later phases are list of the perspective work for in the future that is useful to be considered in development of primary phases of the project. In the proposal development section, the detail elements of this phase, is presented and then it was applied for Varpelev – Hårlev, to give a better understanding of technical elements in the proposal and it is briefly explained how different components of the proposal have been chosen to be part of future energy system in the area and how they are relevant for enhancement of sustainability in the future renewable energy system. On the other hand it can be seen in general how a similar proposal can be designed and prefeasibility study can be carried for different locations. Contribution of this thesis was in transition phase. Some the required steps for transition of a proposal to a project are defined. Based the carried work in this phase, it is concluded that one the major elements in transition phase is to have support from municipality and other key actors that can be pursued by participation and education 1 The presented elements in these phases are identified in the short time of working with this thesis and may need to be expanded and modified in future works. ii and creation of interest for them from the beginning stages and use their feedbacks for improvement of the proposal and its transition to a applicable project. Moreover acceptance of key actors and stakeholders are highly dependent on the economical feasibility of the designed system, which can be achieved by an efficient design through optimization of interrelation between different technical elements of the energy system from input unit to demand units. So the next contribution was series of calculation on technical feasibility of the suggested energy symbioses, that shows that aggregate amount of heat production by suggested symbiosis system will be sufficient to cover the demand for entire year, even when there is an overlap of high demand in both the Varpelev greenhouse and the…
