Unfortunately, the domain of regional energy co-operatives and small utilities has been mainly neglected by IS research. The research in progress paper at hand describes the actual situation of such organizations and focusses on the existing gap in matters of business models (BM) for energy co-operatives. Energy co-operatives are a collaboration by either private persons or smaller companies that produce their own - primarily renewable - energy. Model and theory development of this research are operated by the methods literature reviews, case study research within the energy sector and graphical modeling. The resulting common practice business model based on the business model canvas contributes to the body of knowledge and allows co-operatives to derive own fitting models. The business model canvas is a strategic pattern to visualize the relationship between key partners, key activities and other “building blocks”. This takes the growing importance of energy co-operatives as well as the missing path to market of the new technologies into account.","PeriodicalId":240209,"journal":{"name":"2015 5th International Youth Conference on Energy (IYCE)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126082486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It must be mentioned that there was no 100% successful mission in the “PocketQube” satellite size (50×50×50 mm) which has four times less area as a conventional 100×100×100 mm “Cubesat”. Therefore the PV energy management became really important. The reason behind the SMOG-1 “PocketQube” energy management simulation in Matlab code was to achieve a credible result for the cycle PV energy production to predict the precious amount of energy which could be used to heat the battery of the satellite besides the necessary functions energy needs. In the early stage of the development it was inevitable to encounter some difficulties. One of them was that it was necessary to give basic simulation results to the project team to help their planning phase of the satellite. There were few missing parameters about the structure of the satellite and about the PV cells, which we have managed to get from the literature. As a matter of fact, a 3D design software called SkecthUp and Inventor was used to simulate the shading of the PV modules and software called PVSYST to create the PV module parameters of the satellite and using the calculated parameters necessary codes in Matlab could have been written to simulate the shading of the PV modules. With the obtained cycle PV energy production, the simulation could be run to predict the battery charge level of the satellite for the first cycle. In summary, we have managed to fill the gaps of the simulation and hopefully get conservative, but reliable results.","PeriodicalId":240209,"journal":{"name":"2015 5th International Youth Conference on Energy (IYCE)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114696637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With our paper we would like to draw attention to the usage of these materials, as the next level of heat accumulation. Phase change materials (PCM) are materials used for storing heat energy. To do that these materials use latent heat in the storing process, so PCMs store heat with higher density and release it, when it is necessary. The biggest advantage of these materials is storing huge amount of heat energy with low temperature difference, saving energy and space. In our paper we present the progress of phase change, show the problems with these materials and examine present researches to improve the property of phase change materials. PCMs usually used for storing heat to provide constant temperature that is why these materials are most commonly used in HVAC systems. We can use PCMs in heating systems, built into storages, cooperating with boilers, or we can integrate these materials to wall structures to reduce the effect of outside temperature. In our research we examine a new application, where we integrate a surface heating/cooling system by placing PCMs as different layers of a wall structure. With EnergyPlus software we specify the best position, size and shape of the phase change materials and we also test in which weather conditions is the best to use these materials. We validate the simulation with our own thermal model to make sure it is working properly. Our calculations are based on the heating and cooling energy usage of the building and the level of thermal comfort. Finally we make an economic analysis, in return and the period that our investment pays which we test the off.","PeriodicalId":240209,"journal":{"name":"2015 5th International Youth Conference on Energy (IYCE)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133525551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
