Book Part Citation - WoS: 2Citation - Scopus: 2Energetic and Exergetic Design Evaluations of a Building Block Based on a Hybrid Solar Envelope Method(Springer Verlag, 2018) Mert, Yelda; Saygın, NicelTo achieve sustainable development, there needs to be a focus on decreasing use of non-renewable energy sources and greenhouse gas emissions. In this regard, many studies focus on the strong relationship between energy and the environment. This study aimed to introduce the exergy analysis method into the urban planning field to find out the amount of exergy, rather than energy, that can be conserved in a building block when a solar envelope-based design is applied. In addition to the known energy-efficient design parameters, a criterion for the solar envelop method is integrated into a single method. This hybrid method includes taking into account the requirements for orientation, spacing, landscaping, and building form, as well as the building height properties as proposed in the solar envelop method. The solar envelop method depends on understanding the changing position of the sun throughout the day and year. If this dynamic behavior can be a factor in the design of an urban area, environmental friendliness, sustainability, and reduced energy consumption can comprehensively be achieved in cities.Article Citation - WoS: 7Citation - Scopus: 7Energy Efficient Building Block Design: an Exergy Perspective(Elsevier Ltd., 2016) Mert, Yelda; Saygın, NicelThis study introduces the exergy analysis method into the field of urban planning, in order to find out the amount of energy that can be conserved in a building block when an energy efficient construction design is applied. This was done in four steps. First, energy efficient design parameters were derived from the literature and design alternatives were developed accordingly. Second, data was gathered from the case area for the exergy calculations. Third, exergy analysis of existing building blocks and proposed design alternatives were separately carried out. Finally, the amount of decrease in the exergy loss due to suggested energy efficient design was found out. The results show that the exergy efficiency of the existing building blocks is about 2%, while the proposed design alternatives will be around 10-11%. The overall exergy loads of the alternative plans were found as 166.3 W, 225.1 W, 142.5 W and 137.8 W respectively for winter and 105.4 W, 140.0 W, 89.9 W and 86.3 W respectively for summer, on a housing unit basis. As a result, the suitability and importance of the exergy analysis on the built environment was proven, by revealing actual and considerable energy conservation and sustainable use of energy through application of energy efficient design parameters.Doctoral Thesis Application of Exergy Analysis Method To Energy Efficient Building Block Design(Izmir Institute of Technology, 2014) Mert, Yelda; Saygın, Nicel; 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.
