Çevreye Duyarlı, Enerji Etkin Kamu Binalarının Sürdürülebilirliğinin İncelenmesi

Abstract

In the last decade, Turkey has made significant progress in energy efficiency. Despite the introduction of many laws, regulations and directives, the use of energy in our buildings is well above the equivalent consumption of developed countries. Our country, importing more than 70% of the total energy used, urgently needs to reduce her energy dependency starting from the buildings whose energy loss is very high. It is stated that, as in the European Union countries, it is necessary to start energy efficiency applications with public buildings by using the purchasing power of the government. Within the scope of the thesis, the procurement information for strengthening & renovation investments and pre-&post-investment energy expenditures of three different sized public buildings in three different climatic zones are provided. Sustainability and rantability of the investments are analysed by using energy savings in terms of World Bank and EIB financing criteria (Benefit-Cost and LCOE Levelized Cost of Energy Analysis). Regarding renewable energy production in public buildings; the minimum roof area required for public buildings is calculated based on the World Bank criteria with LCOE analysis. Regarding the applications of cogeneration and trigeneration in public buildings; the relevant laws and guidelines are put forward and the studies of different public institutions are compared. The trigeneration system established in new building of the Ministry of Environment and Urbanization is analysed with EIB criteria through Primary Energy Saving (PES) and LCOE. Regarding energy efficient, environmentally-friendly buildings; both public and independent institutions have carried out similar studies by taking the international evaluation systems as an example. However, the first domestic evaluation systems prepared without taking into consideration the economic conditions of our country have not been preferred until the last five years. Not only technically but also economically sustainable evaluation systems will be successful and the desired objectives will be achieved with the support of public pioneering and government incentives.
