The main objective of this study is to develop a methodology by using the actual data of residential natural gas consumption in order to compare the efficiency levels of the three different residential heating systems. Such comparison is considered crucial to support better policy-making. Since final consumers are the subscribers of natural gas distribution companies regulated by Energy Market Regulatory Authority of Turkey, natural gas distribution market conditions and related regulations are taken into the account while developing the methodology. This is also expected that the methodology would be usefull for similar studies for different natural gas distrubition regions of Turkey. Apartments constitute a larger share of Turkeys housing stock. Three residential heating systems prevail in most of these apartment blocks: standalone heating v systems (individual unit based), central heating systems (block based) and district heating systems (neighborhood based). In this research, apartment blocks with these three different heating systems are examined in order to compare energy efficiency of and carbon dioxide emissions from their heating systems. Natural gas based residential heating systems are particularly dealt with due to data availability and extensive use. Results of the comparative analysis are applied to citywide housing stock data so as to find out the potential emission reductions in case widespread use of central and district heating systems are achieved in cities of Turkey.
