Development for Co2 emissions reduction by the use of solar thermal collectors in the process of urban planning

Abstract

Using renewable energy sources is one of the most important characteristics of the sustainable and resilient development. Nowadays, need to minimize CO2 emissions is obligatory, especially in the sector of urban and architectural planning, since in Serbia approximately 50% of produced energy is spent in buildings. CO2 emission, in urban structures, can and must be reduced at the different levels: building level, block and city level. For the city of Kragujevac, based on urban parameters defined in General urban plan, typical urban block was chosen and typical building structure developed. Calculation were made, based on recommendations developed by the Ministry of mining and energy and Serbian regulations, for the energy needed for domestic hot water preparation. In this paper, the influences of architectural and urban parameters on the use of solar thermal collectors at the typical building and urban block level is investigated. Recommendations are prepared for principles of urban and architectural design in order to enable the use of collectors for domestic hot water preparation and in that way CO2 emission reduction. Developed methodology for the city of Kragujevac can be applied in defining design principles in whole the country and Balkans region, not only for the use of solar thermal collectors but also for the use of other renewable energy sources.
