Öğe Energy efficiency and thermal comfort analysis of traditional Diyarbakır inn(IJSER, 2019-09) Kallioğlu, Mehmet Ali; Yılmaz, Adem; Ünvar, Sinan; Beştaş, BilalThe traditional structures of Diyarbakır is reflect centuries of Mesopotamian culture interms of planning. Beside the walls of Diyarbakır, many buildings and traditional houseswere built with the most suitable materials and components depending on the climaticcharacteristics. It is easy to recycle to the environment because it is made of naturalmaterials and the design in which it conforms to the climatic and geographical structureof the environment in which it is located. In addition, it accommodates ecological andsustainable design criteria with its structure providing comfortable indoor environmentsthat can heat and cool without requiring additional measures. Nowadays, energy efficiencyand thermal comfort analyzes of these designs have been made with the engineeringsimulation program Autodesk Ecotect Analysis. In this study, thermal analysis and solarintensity of Sülüklü Han which was built in 1680 in different days, months and seasonswere investigated. National (BEPY) and international (ASHRAE) standards were evaluatedand simulated as a result of the simulations. Because fossil fuels have come to the end.With this study, energy efficiency of traditional buildings will be examined and energyefficiency will be provided for new buildings. Thus, maximum utilization of solar energy willbe achieved and energy saving will be achieved. title.Öğe Empirical calculation of the optimal tilt angle for solar collectors in northern hemisphere(Taylor & Francis, 2020-03) Karakaya, Hakan; Kallioğlu, Mehmet Ali; Durmuş, Aydın; Yılmaz, AdemPanel tilt angles (0°–90°) need to be in a proper position and location to get maximum productivity from solar energy. Values used in solar energy applications are generally computed by (global, diffuse, and direct) variation on horizontal surfaces calculated using isotropic sky and a mean albedo method. Being parallel to the available literature concerning such applications, this study focuses on the optimum solar panel angle. In this study, optimum solar panel angle value by months was determined for three sample provinces (Antalya, Kayseri, and Trabzon) first and North Hemisphere then. Capacity calculation of sample provinces was performed based on monthly, seasonal, and annual angle values and horizontal situation. Monthly and annual optimum angle values for Northern Hemisphere by 1° increase for between the latitudes of 1° N and 65° N. While the panel angle is at the highest level in autumn and winter (November-December-January and February) in annual process, the lowest angle is observed in spring and summer (May-June-July-August). Several different mathematical models have been developed for the sample provinces and Northern Hemisphere. While the variable of 12 different models that were developed for provinces is the Declination (δ) coefficient, the variable of 7 different models that were developed Northern Hemisphere is the latitude (Ø). Regional values in literature with estimation results of models were analyzed based on NASA and PVGIS data color scale. There was created a possibility of comparison by aligning all the optimum solar panel angle values of related location via a scale whose values vary by 1 and 10. Moreover, all the models were verified by statistical analysis methods. R2 (determination coefficient) in 19 different estimation equations is pretty close or equal to 1. However, the best among them is Eq. 32 (0.9979) for sample provinces and Eq. (33) (1) for the Northern Hemisphere; developed models are less-than-stellar. Other statistical data of these equations are MBE (−0.0616), RMSE (1.1176), t-sat (0.1830), Bias (1). For Eq. (32); MBE (1.96), RMSE (2.75), t-sat (8.13), MPE % (3.98), MAPE (5.87), SSRE (0.27), and RSE (0.06) for Eq. (33). The statistical analyzes indicate that all regression models are applicable in Turkey and Northern Hemisphere. Developed all correlations are recommended for academic and industrial users.
