Investigation of environmental ımpacts of energy utilization in space heating

Abstract

This study presents the analysis of the energy and exergy utilization of the Bali{dotless}kesir space-heating sector (BSHS) in the years of 1996 and 2010 and environmental impacts of their usage. In this analysis, actual data were used in the calculations. Total energy and exergy inputs are calculated to be 3.58 and 3.68 PJ in 1996, while they are determined to be 4.55 and 4.69 PJ in 2010, respectively. Annual fuel consumptions in space heating are determined according to appliances. The overall space heating energy efficiency value for the BSHS is found to be 48.46 % in 1996, and is determined to be 66.89 % in 2010. The exergy efficiency value for that is obtained to be 3.26, 3.83 % in the analyzed years, respectively. The present study clearly indicates the necessity of the planned studies towards increasing exergy efficiencies and decreasing emission values in the sector studied and especially the critical role of policy makers in establishing effective energy-efficiency delivery mechanisms throughout the country. It may be concluded that the current methodology is useful for analyzing the sectoral energy and exergy utilization, giving energy saving opportunities.
