Assessing renewable energy sources and climate change
Covering the energy demand of cities and urban areas is a challenging task and with the current concerns about climate change and the increased trends of urbanization, it will be more challenging in future. The current urge of adding more renewable sources to energy systems is a response to that concern as well as being affected by the situation of the traditional energy sources such as fossil fuels and nuclear energy plants. Although having more renewables will decrease CO2 emissions, it brings several challenges. For example renewable energy sources such as solar radiations and wind are not always available and their variations are large in different time scales, from hourly to seasonal. Having a secure flow of energy in an urban area is very important; it is vital to cover the demand during whole year, especially on peak hours and extreme conditions which will happen more often according to predictions about future climate.
This project intends to assess the future conditions for urban areas with several buildings and to deeply analyse the probable energy demands for future climate. Several future scenarios will be considered for future climate, urbanization, technical advance and etc. Energy performance of urban areas will be assessed thoroughly by looking into buildings as the demand/generation nodes of the energy grid and by quantifying the potentials for integrating more renewable energy sources in the energy system. More than centralized energy systems, several decentralized solutions such as energy-hub will be considered in the assessment. Both the long and short term performance of system will be assessed for future climatic conditions, considering several climate scenarios as well as extreme climatic conditions. Adopting a probabilistic analyses, the importance of several uncertainty factors in the assessment of the reliability and robustness of the energy system will be analysed. More than creating strong professional links with some of the best research groups in the field, running this project will expand the impact assessment of climate change towards buildings and energy systems in urban areas, providing a comprehensive view about future urban energy systems, role of buildings as distributed nodes and possibilities to face future challenges.
