Doctoral Thesis Application of exergy analysis method to energy efficient building block design(Izmir Institute of Technology, 2014-03) Mert, Yelda; Saygın, NicelThis dissertation introduces the exergy analysis method into urban planning field in order to find out the amount of energy that can be conserved in a building block when energy efficient design is applied. Two hypotheses are developed here: 1. Exergy analysis is a suitable tool for the built environment, and 2. Energy efficient design parameters provide energy saving in the built environment. A case study approach is undertaken in order to test the hypotheses stated above. To do this, first, the energy efficient design parameters have been derived from the literature and design alternatives are developed accordingly; second, data has been gathered from the case area for the exergy calculations; third, exergy analysis of existing building blocks and proposed design alternatives are carried out, and finally, the amount of decrease in the exergy loss due to energy efficient design is found out. The findings in this study show that the exergy efficiency of the existing building blocks is nearly 2 %, while the proposed design alternatives are nearly 10-11 %. The overall exergy loads of the alternative plans are found as 166.3W, 225.1W, 142.5W, 137.8W and 184.8W respectively for winter and 105.4W, 140.0W, 89.9W, 86.3W and 125.3W respectively for summer on a housing unit basis. These results are much better when compared to the existing situation per housing unit which is 1079W (winter) and 1173W (summer). The best alternative energy efficient planning and design brings 1631 W (winter) and 2810W (summer) of exergy saving that corresponds to 799 TL/year and 978 kg/year reduction in CO2 greenhouse gases emission per housing unit. This data shows that the expected results and are in harmony with the literature. As a result, the suitability and importance of the exergy analysis on the built environment is proved by revealing the energy conservation and sustainable use of energy through using energy efficient design parameters.Master Thesis The changing role of planners in local planning practices: A comparetive analysis of two planning studies of Izmir(Izmir Institute of Technology, 2009) Mert, Yelda; Kaya Erol, NursenThe main goal of this thesis is to understand the changing role of urban planners in a historical perspective. Moreover, the historical perspective of the role of planners is investigated parallel to the changes in planning. To understand the role of planners, especially in the planning practices of Turkey, the period before and after the 1980s are examined. Initially, planning theories and relevant theoretical studies as well as case studies from around the world are analyzed in terms of the role of planners. To understand the role of planners before and after the 1980s, two comprehensive planning studies are selected from İzmir, Turkey. One of them is the 1973 Master Plan prepared by İzmir Metropolitan Planning Office and the other is the 2007 Master Plan prepared by İzmir Metropolitan Municipality. The in-depth interview method with the planning staff is used as the methodology of the thesis.
