Economic Impact of Exergy Efficient Building Block Design
(int Journal Contemporary Economics & Administrative Sciences, 2017) Mert, Yelda; Saygin, Nicel; Mert, Suha Orcun
Even after the end of 20th century, the details of connection between energy especially energy production-and the environment were not fully understood. The population growth in last thirty years, undeniable climate changes and the starvation of non-renewable energy source reserves leaves no room for doubt, however: energy and environment share a strong and significant connection. This perspective is especially important in the world of economics, considering the cost of energy for end users. This study covers the economic impact and gain of applying exergy efficient planning to a building block. The study hereby undertakes a case study to show that an efficient planning can help save energy, and thus money. The existing blocks of the chosen case had 2% energy efficiency, while the designs proposed in the study have 10-11%. The findings in this study show that an 8 % improvement in the exergy efficiency of the building block results in 780.05TL saving for a single housing. This sums up to 54.603,49TL for the building block annually.
Energy Efficient Building Block Design: an Exergy Perspective
(Pergamon-elsevier Science Ltd, 2016) Mert, Yelda; Saygin, Nicel
This 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 863 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.

Exergy Analysis of Mass Housing Areas: Mavisehir I and Ii, Izmir
(inderscience Enterprises Ltd, 2015) Mert, Yelda; Saygin, Nicel
In this study, in terms of urban design, an exergy analysis of Mavisehir mass housing area in Izmir, Turkey is carried out based on spatial properties, shadow effects, wind effects and local climate to understand the importance of design strategies. The exergy analysis is applied with broad consideration covering the heat loads of the separate buildings for winter and summer. When the exergy results of Mavisehir I and Mavisehir II are compared it is found that Mavisehir II has less exergy by fuel and exergy load values. This may result from different design strategies in Mavisehir I where the same buildings and villas between residential buildings are located according to sea view, whereas in Mavisehir II, there is a heterogeneous pattern with various forms and heights of the residential buildings. It was also discovered that exergy efficiency of the area is 4.20% and the exergy flexibility factor is 19.3%.
