    On-Site Measurements of Temperature and Humidity Conditions for the Comparison of Urban and Rural Sub-Spaces of Traditional Settlements: Historical City of Muğla, Turkey
    (Taylor and Francis Ltd., 2024) Timur,B.A.; Başaran,T.; İpekoğlu,B.
    One of the significant processes that ensures realistic determination of the energy needs of historical buildings is case-specific definition of their local microclimatic conditions. Accordingly, the aim of this study is to determine differences for the parameters of temperature and humidity in urban and rural sub-settlements of the historical city, Muğla/Turkey. Study method consists of on-site measurements of these variables in sub-settlements for comparisons. As a result, it was identified urban zone shows heat island characteristics with warmer, drier, and more stable conditions; while rural sub-settlement remains cooler, more humid, and more erratic. In parallel, calculated extents of these differences demonstrate the significance and necessity of on-site measurements and consequential microclimatic zoning of historical cities as conservation/planning tools for responding to the thermal needs of architectural heritage. A key application of these processes would be the establishment of local databases of case-specific weather data to be used in thermal simulation assessments. © 2023 Taylor & Francis.

    EXPERIMENTAL AND ANALYTICAL EXAMINATION OF THE EFFECT OF DOUBLE SKIN FAÇADE SYSTEM ON BUILDING THERMAL PERFORMANCE;
    (Turk Isi Bilimi ve Teknigi Dernegi, 2021) Hülagü,S.; Göksal Özbalta,T.; Başaran,T.
    In this study, heat transfer in conventional single skin façade and double skin façade system was studied experimentally and numerically by using one dimensional time dependent approach and the effects of the façade systems on building energy performance especially heating energy was investigated. In this context, a mathematical model considering user behavior and window aluminum frame element effect was build by zonal analysis method to calculate the heat transfer in single and box type closed cavity double skin façade systems, and build model was experimentally verified. Experimental study was conducted in office spaces having single and double skin façade systems in Ege University, Civil Engineering Building’s south façade in January 2017. Next, verified model was used to study the heat transfer in the façade systems for İzmir’s climatic condition by using monthly average daily data. The change in thermal performance of single and double skin façade systems due to the climatic condition during a year was investigated by using the 10 year average climate data of İzmir (Mediterranean climate). It was found that double skin façade system acts as an insulator preventing extreme indoor temperature values, thus contributing to the indoor comfort level against changing outdoor conditions. ©2021 TIBTD Printed in Turkey.

    Experimental Investigation on Heat Transfer and Air Flow Behavior of Latent Heat Storage Unit in a Facade Integrated Ventilation System
    (Elsevier Ltd, 2021) Pekdogan,T.; Tokuç,A.; Ezan,M.A.; Başaran,T.
    All-air central HVAC systems are widely applied to provide fresh and conditioned air, which is very important for users to lead healthy and productive lives. Decentralized systems are another mechanical solution to ensure indoor air quality and thermal comfort with a heat recovery ventilation system integrated into the building wall. These commercially available systems store sensible energy in the heat exchanger. In this study, an experimental real-size staggered tube bundled prototype with phase change material (PCM), which stores latent thermal energy, was proposed/designed and full-scale experiments were carried out in laboratory conditions. The experimental setup includes two spaces that simulate indoor and outdoor conditions that are separated by an insulated aerated concrete wall. In the prototype, two ducts embedded in the wall contain staggered tube bundles filled with PCM, which are positioned perpendicular to the airflow to recover heat for supply and exhaust ventilation modes. The thermal performance of this prototype is investigated for different operating times, namely, 15, 20, and 30 min. The average air energy change of the latent heat recovery ventilation system values is between 20 and 35 kJ approximately for the operating times. The supply mode efficiency result is an average of 50% and exhaust mode efficiency is 25%. © 2021 Elsevier Ltd
