The optimum insulation thickness of the external wall for four cities from four climate zones of Turkey, energy savings over a lifetime of 10 years and payback periods are calculated for the five different energy types and four different insulation materials applied externally on walls. Extruded polystyrene, expanded polystyrene, nil siding and rock wool as wall insulation material are selected. In this study, the net energy cost savings are calculated using the P1-P2 method. The results show that energy cost savings vary between 4.2 $/m2 and 9.5 $/m2 depending on the city and insulation materials. The highest payback period value with 2.25 years in Mersin found by using natural gas as an energy source for heating, while the lowest value is reached by using LPG as an energy source in Bitlis. © 2009 Elsevier Ltd.

In this study, the thermal conductivity and mechanical properties of samples produced by mixing waste fly ash (FA), natural clay (C) and epoxidised palm oil (EPO), the renewable material, were experimentally investigated. FA and C were used as the raw materials for sample production and the sample EPO was the binder. The experimental results revealed that higher proportions of both FA and EPO reduced the thermal conductivity coefficient, mass, compressive strength and tensile strength of the samples. The lowest, and therefore best, value of thermal conductivity obtained was 0.255 W/m K and this was measured for the sample with a 70% FA to 30% C ratio mixed with 50% EPO and processed at 200°C. However, this sample had the lowest compression and tensile strength values, 1.5 and 0.428 MPa, respectively, and the highest abrasion loss at 5.55%. The highest compression and tensile strengths and the lowest value of abrasion loss, at 4.26 MPa, 0.722 MPa and 1.27%, respectively, were observed for the sample with a 30% FA to 70% C ratio mixed with 40% EPO and processed at 160°C. However, this material combination had the highest thermal conductivity at 0.428 W/m K. © 2010 Taylor & Francis.

This study defends that solution to environmental and even social problems faced around the house which is the basic habitat has relations with space design. Therefore, spatial characteristics supporting social togetherness, cohesion and communication especially among different social groups living together in urban transformation areas have been analyzed. The research question of the article has been set as "How must the landscape characteristics be to support social interaction of the individuals around the house?". In this study, the importance of landscape design as a tool to lead individuals to outside spaces, socializing and being together has been tried to be stressed and space design tools that can be used to provide social interaction and the feeling of being a community especially in transformation places which are problematic have been examined. Çukurambar District which has gone through a very fast transformation period has been chosen as a research area. Existence of some places which have not transformed has given chance to examine the spatial behaviors of individuals from different physical and social conditions. In order to concretize the study and to get quantitative data, a questionnaire which examines the relationships among individuals, places and neighborhoods has been conducted in the transformation area and the results are evaluated. It is the aim of this study to be a guide for the spaces which will be transformed and new residents in creating social interaction places. © 2010 Academic Journals.

In this study, the optimum thickness of insulation considering condensed vapor in external walls are found by using thermoeconomic analysis. The four various cities from four climate zones of Turkey, namely, Hatay, Adapazari{dotless}, Konya and Mus are selected for analysis. The optimum insulation thickness for Hatay, Adapazari{dotless}, Konya and Mus are obtained as 0.036, 0.045, 0.06375 and 0.07 m at indoor temperature of 20 °C, respectively. The results show that the optimum insulation thickness at the indoor temperature of 18 and 22°C are determined as 0.044 and 0.065 m for the city of Adapazari{dotless}, respectively. When the optimum insulation is applied, the energy saving for Adapazari{dotless} is obtained about 64% for the indoor temperature of 18 °C, 77.2% for the indoor temperature of 20 °C and 80.3% for the indoor temperature of 22 °C. © Sila Science.

The risk formula, expressing the probability of at least one occurrence of earthquakes of greater-than-design-value magnitudes over the economic life of a structure, is modified taking into consideration the probability of no-earthquake years. The annual maximum earthquake magnitudes of three scales: Richter magnitude, also known as local magnitude (M L), body-wave magnitude (M b), and moment magnitude (M M) in a geographical area encompassing the Bingöl Province in Turkey are taken from two sources: (1) report by Kalafat et al. (2007) [14] and (2) the web site reporting data by Kandilli Observatory which has been recording earthquakes occurring in and around Turkey since 1900. Statistical frequency analyses are applied on the three sample series using various probability distribution models, and magnitude versus average return period relationships are determined. The values of the M L, M b, and M M series for 10% and 2% risk are computed to be around 7.2 and 8.3. The tectonic structure and seismic properties of the Bingöl region are also given briefly. © 2012 Elsevier Ltd.
