Investigation of Energy Supply of a Residential Area from Renewable Energy Sources: The Case of "Our City-Konya Project"

Abstract

Approximately 25% of the total energy consumed in the world is used in residences. Considering that approximately 80% of the total energy consumption is from fossil fuels polluting the environment, it is seen that the energy sources used in settlements have an effect of 20% on environmental pollution and greenhouse effect. In this article it has been investigated whether the entire energy of the settlements can be produced by using renewable energies, mainly solar and wind energy. This research was carried out in an exemplary settlement in Konya within the scope of the "Our City-Konya" project completed in November 2019, which was prepared for the Ministry of Environment Urbanization and Climate Change. Developing designs within the framework of environmentally sensitive and sustainable approaches in urban planning are the goals and basic principles of the strategy plan. Within the framework of these principles, it is important to reduce the deteriorating global climate effects by providing renewable energy production and efficiency in settlements. In this context, measures have been taken in design studies of the field in order to provide energy efficiency in urban design work and to reduce the negative effects of climate change. Within the scope of the study targeting the concepts of ecological (environmental) and sustainable cities it is aimed to set an example for new applications to be made in the project concept. Türkiye has a very good potential in terms of solar and wind energy capacity from renewable energy sources. Especially in Konya, in which the research area is existed, the potential for solar energy is quite high. In the area planned to have a population of 20,000, buildings are designed as detached block of 2, 4 and 6 storey. It has been determined that it may be possible to meet the heating energy of the settlement with soil and solar heat pumps in winter, but the cost will be very high in today's conditions. It has been designed that the electrical energy and hot water needs of all residences, including official and social facilities in the planning area, can be met with solar PV-T and wind energy systems suitable for the settlement.
