After releasing the regulations on unlicensed electricity generation in Turkey, the main structure of the regulatory mechanism has just finished in 2014 and renewable energy generation started to grow dramatically. Ozyegin University Campus Wide Solar Energy Application is the first large-scale building integrated, grid-connected system. From the idea of the project to the implementation processes, it is a great success story for the development of the academic researches and solar energy market. The complete process of technical, economical and bureaucratic side will be investigated for the future development while giving insights about the operation period as well. Ozyegin University has completely rooftop PV system distributed on 4 buildings with a total capacity of 378 kWp. The whole system has a unique design that could be implemented on each buildings similarly. Solar energy production simulations with 4 different database systems, selection of the each component, complete system design, 3D models, financial analysis, static measurement and reports, governmental appointment mechanism, legal approval, installation, commissioning and operation are the main topics that will be covered within the thesis. The most important extraction over the analysis of system outputs is the Operational Performance Index, which should be used as a performance KPI for the photovoltaic system. At the end, the value and the originality will come from not only the system integrity but also modals generated for the development of the market.

Integrated engineering and architecture for the energy efficient academic buildings
(International Building Performance Simulation Association, 2015-12) Mengüç, Mustafa Pınar; Somuncu, Yasemin; Çağlayan, Şahin; Özcan, Saadet; Sefer, Burak; Simitli, Utku; Mechanical Engineering; MENGÜÇ, Mustafa Pınar; Çağlayan, Şahin; Özcan, Saadet; Sefer, Burak; Simitli, Utku
In this paper, we outline a comprehensive and integrated collaboration between engineering and architecture team to build an energy efficient building. Within the framework of the EU FP7 project, titled NEED4B, we have been instrumental in design, construction and operation of a new highly energy efficient education building in the campus of Özyeğin University in Istanbul. The building was completed in 2013 although its monitoring will continue until 2018 to evaluate the performances of all subcomponents and that of the overall structure. The initial evaluation of the energy consumption of the building shows that it is better than the targeted value of 60 kWh/m2/year, following a detailed and integrated study. The details and the problems faced during this undertaking are discussed in the paper.
