Çalışma kapsamını sınırlamak amacı ile beş hastane seçilmiştir. Örnek alınan hastanelerin hem kent hem de yakın ve uzak çevreden gelen hastaları kabul eden hasta kapasitesi yüksek hastaneler olmasına dikkat edilmiştir. Devlet ve özel hastanelerden seçilen örneklerden birisi yöre hastanesi görünümünde olmasına karşın konumu nedeni ile çevreden kapasitesi üzerinde hasta kabul eden devlet hastanesi, birisi yine geniş bir bölgeden hasta alan özel üniversite araştırma hastanesi, bir diğeri Karadeniz bölgesi çevresinde geniş bölgeden hasta kabul eden devlet üniversitesi hastanesi, ikisi Ankara merkezinde devlet üniversitesi araştırma hastanesidir. Sonuçlar eşdeğer ses basınç seviyeleri (her alanda 20 noktadan 5er dakikalık Leq şeklinde olmak üzere), Lmax, Lmin ölçümleri fast ve slow mode olarak alındı. Türkiye ve Amerika Birleşik Devletlerinden alınan örnek hastanede elde edilen sonuçların, Dünya Sağlık Örgütü (WHO)nün kabul edilebilir bulduğu seviyelerin üzerinde olduğu tespit edilmiştir. 24 saatlik ortalama aralıkta ortalama eşdeğer basınç seviyesi Amerikadaki hastanelerde 50-60 dB(A) Türkiyedekilerde ise 55-75 dB(A) arası olduğu belirlenmiştir. Bu seviye aralıkları 30- 100dB (düşük mod) ve 50-120 dB (yüksek mode) arasında değiştirerek ölçülmüştür. Spektrum makine seslerinin de değerlendirilebilmesi için 16- 8000 Hz. arasında Lmax-Lmin azami için oktav bantlar ve Leq ölçümleri için A-ağırlıklandırma şeklinde ölçülmüştür. Spektrumları çizelgesine göre, düşük frekanslar olan 63-500 Hz oktav bantları içinde genellikle düzdür, 500-4000 Hz artış göstermekte, 4000 Hz. üzeri insan sesi seviyesi üzerindeki frekanslarda ses basınç seviyeleri düşmektedir. Son altı yıldır alınan ölçümlerden oluşturulan grafikler geceleri ortam ses seviyelerinin belirgin biçimde düştüğünü, gündüzleri ise ulusal ve uluslararası standartların çok üstünde olduğunu göstermektedir. Ölçüm sonuçlarında elde edilen kabul edilebilir ses seviyesinden yüksek sonuçların kullanıcılar üzerindeki etkileri hastanelerde yapılan anketler ile de desteklenmiştir.Article A Modeling Approach for Designing New Acoustic Materials(Gazi Univ, 2024) Koçyiğit, Filiz Bal; Köse, Ercan; Buluklu, Hatice Mehtap; Bal Kocyigit, FilizIn this study, mathematical modeling design based on Sound Transmission Loss measurement results of new acoustic material samples with natural content was carried out. Using the test samples in question, transfer function of acoustic materials based on electronic filter circuit design and a transition design method for the production of new acoustic materials by utilizing the transfer function is presented. Based on the experimental results of the test samples, it is the most suitable low-pass filter structure for the proposed design. In this study, active Sallen-Key low-pass filter structure is preferred and used. Sound Transmission Losses in dB (decibels) of acoustic samples were obtained experimentally for 500, 1000, 2000 and 4000 Hz. fundamental frequencies in the literature. Based on these data, transfer function simulation suppression gain results were obtained in TINA-TI program, active filter circuit designed, and MATLAB program. When the other results were compared in the experimental results, it was seen that very close values were obtained. It has been demonstrated that the proposed method can be used effectively in the design and examination of new acoustic materials.Article Citation - WoS: 1Citation - Scopus: 2A Critical Review on Multifunctional Building Envelope Materials for Simultaneous Mitigation of Urban Heat and Noise Islands(Springer int Publ Ag, 2025) Sarul, Meltem; Kocyigit, Filiz Bal; Yilmaz, CagriRethinking urban models requires resilient designs providing solutions to environmental problems at the building scale. Urban Heat Islands (UHI) and Urban Noise Islands (UNI) often coexist and significantly affect human health and comfort. This article aims to examine dual-function building envelope materials for reducing urban heat and noise islands using the literature review method. Dual-functional building envelope materials provide versatile benefits such as increasing energy efficiency, mitigating environmental challenges in densely populated areas, and improving individual and social health and comfort, in addition to their thermal and acoustic benefits. The use of these materials in building envelopes supports the climate adaptation of cities and provides resource efficiency.High albedo cool materials used for excessive heat reduction can be in the form of cool roofs or cool walls. High reflective materials, cool colored materials, retro-reflective materials, photoluminescent materials, thermochromic materials and sustainable materials are the most common among the cool material alternatives. The use of natural and local white colored gravel of various sizes on cool roofs is a low-cost and efficient approach to UHI reduction. Cool colored materials reflecting the near-infrared part of the solar spectrum bring a suitable solution for historical buildings where white color application is not appropriate. Highly reflective materials combat heat-related risks by reflecting incoming solar radiation directly back to their source due to their special content. Photoluminescent materials, which are still in the research phase, and thermochromic materials that change color when they reach a predetermined temperature are other solutions used to prevent heat-induced problems. Recycled or paraffin, biowaste oil added Phase Change Materials (PCM) also offer environmentally friendly, sustainable solutions for this case. In terms of UNI mitigating techniques, sound absorbing materials with high sound absorption coefficient and low density are widely preferred for building envelopes. Since high albedo materials generally have low sound absorption capacity, although reduction in heat- and noise-related threats is possible separately with the building envelope materials to be selected, multifunctional surface design diminishing both UHI and UNI effects simultaneously still involves various challenges. However, there are various strategies including applications of green walls and green roofs. Innovative approaches such as the use of PCM in pavements or the conversion of noise into green electricity using resonators or acoustic metamaterials also exist. While such solutions have not yet been widely found in practical applications, they are promising for the resilient smart cities of the future. Further experimental validation is needed to evaluate the long-term performance, cost-effectiveness and climate-specific applicability of multifunctional materials.HighlightsMulti functional building envelope materials that simultaneously address UHI and UNI offer great opportunities to create resilient future designs.Using cool materials in building envelopes mitigate UHI related risks.Using sound-absorbing materials in building envelopes mitigate UNI related risks.Innovative solutions such as phase-changing materials and converting harvested noise into electricity are great future opportunities.Article Citation - WoS: 4Citation - Scopus: 3NOISE FACTORS IN HEALTHCARE FACILITIES: A SURVEY OF HOSPITALS IN TURKEY(Middle East Technical Univ, 2012) Bal Kocyigit, Filiz; Koçyiǧit, Filiz Bal; Architecture[No Abstract Available]Article Citation - WoS: 1Zero Consumption Monotype Education Buildings(Gazi Univ, 2018) Bal Kocyigit, Filiz; Koçyiğit, Filiz BalTurkey has mainly seven geographic zones but four climatic zones. Major influence on energy usage and educational buildings which perform well in energy terms will reap significant environmental and economic benefits for years to come. The lack of electric, heating-cooling and lighting comfort in the structure reduce the quality of education. Many village schools cannot provide training in enough conditions. Municipalities are preparing "Type School Project" for government schools, without thinking different zones conditions, directions and heights. At this stage, there arises importance of the Architectural Design Process for typical energy efficient design which can easily adapt to the location. The material must not only be transmits about 70-90% of solar radiation, but also its insulation quality. Additionally architectural form of building must be affected to take all solar energy, wind and water. In this study, architectural design method has been used for energy gain from transparent insulated trombe wall. And have been calculated in accordance with their manners in the middle, south, noth, east and west regions of Anatolia which are located in different degree-days regions on the basis of TS 825.Article HASTANELERİN PEDİATRİ BÖLÜMLERİNDE GÜRÜLTÜ VE KULLANILABİLECEK ÇÖZÜM ANALİZLERİ(Cumhuriyet Gazetesi Bilim ve Teknoloji Eki, 2015) Bal Koçyiğit, FilizÜlkemizde yoğun hasta taleplerinden dolayı tam teşekküllü hastanelerde gürültü, önemli sorunlardan birisi olarak karşımıza çıkmaktadır. Hastanelerin çocuk hastalıkları bölümünde ise gürültü sorunu daha ciddi boyutlara ulaşmaktadır. 0 – 18 yaş grubu çocukların hastanede, doktorlara karşı tepkisi farklıdır ve bu aralıktaki yaş grubu çocukların seslerinin frekansları da farklılık göstermektedir: 1) 0 – 5 yaş grubu çocukların seslerindeki frekans aralığında kız- erkek seslerinin frekans ayrımı azdır ve yüksek frekanslı sesler oluşturmaktadırlar. 6 – 12 yaş grubu çocuklarda ise kız- erkek seslerinde frekans ayrımı başlamakla birlikte yüksek frekanslı sesler oluşturmaktadırlar ve net ayrım görülmemektedir. 2) 13 – 15 yaş arası çocukların seslerinde frekans farkı başlamakta kız seslerinin tizliği artarken, erkek seslerinde kalınlaşmalar oluşmaktadır. 3) 16 – 18 yaş grubunda artık frekans ayrımları netleşmeye başlamaktadır. Küçük yaş gruplarında, ağlama, oyun amaçlı bağırma gibi seslerin yoğun olması yanında ortamdaki ses seviyesinin yüksekliği ve uğultu bu grupta sinirlilik, sabırsızlık, sızlanma ve ağlama eşiğini arttırmaktadır. Hastane yapılarının içinde bulunan cihazlardan, çevrelerindeki seslerin ve çalışma ortamından kaynaklanan seslerin gürültüye dönüşmesi çocuklar üzerinde olumsuz etki yaratırken çocukların ürettiği ses düzeyini de arttırabilmektedir. Sürdürülmekte olan çalışmanın amacı iç mekan gürültüsüne dönüşen seslerin etkilerini araştırmak, gürültüyü doğrudan etkileyen çınlama sürelerini var olan örnekler üzerinde ölçmek, analizlerini yapmak elde edilen verilere dayanarak mimari tasarım yöntemleri ile alınabilecek önlemleri yalıtım unsurlarını tespit ederek mimari projelere yansıtmaktır.Article Effective Use of Solar Energy With Bim Supported Parametric Methods: Case Study Al-Shaab Stadium(2021) Koçyiğit, Filiz Bal; Allawı, AbdullahIn this study, it is aimed to create an infrastructure that can contribute to the integration of parametric techniques and the joint work of construction and architectural science through an exemplary building design. The ability to respond to changes in data entry in algorithms gives architectural designers the opportunity to optimize structures and form at the same time. At the same time, replacing inputs with parametric techniques saves time in the design process. Otherwise, the design will have to be redesigned from the beginning, depending on the periodic change made in the design. In addition to this, it has been emphasized to build a building design and structure that will provide energy efficiency. In order to create low cost in profit-cost ratios, the possibility of minimizing the inefficient surfaces with the design method by analysing the floats with maximum energy gain due to creating solar plans. The algorithmic design used for this is modelled on the visual and optimizes the geometry to achieve maximum energy efficiency for the building form. To find solar panels suitable for the building geometry design, there is a need to model the actual effect of the sun's rays on the building. One of the key parameters that helped us reach the results of the study is to explore the possibility of using modern guidelines of exemplified stadium designs. This research is based on a method of comparing analysis between two prototype proposals tested to show the effect of the sun on geometry using parametric algorithms. In this case, \"Grasshopper 3D\" software was used for radiation, daylight hours and shadows to create parametric algorithms in the solar effect simulations process. The purpose of using parametric simulation was to increase energy efficiency for the stadium. Additionally, generative design was used for structural optimization. In this study, generative design was also used to optimize the stadium design structure, which helps to significantly reduce the amount of materials used in the formation of the structure and its costs. In this study, with the help of the Buiding Information Modelling (BIM) program used, solar energy gains affecting the building were investigated and energy gain-loss calculations were made by using environmental data. The obtained data and shell design samples were compared. In the study, Al Shaab stadium in Baghdad was evaluated as an experimental model for modelling the reality.Article Citation - WoS: 2Citation - Scopus: 3Low-Cost Alpha Cabin Like Test Box Proposal for the Development of New Acoustic Sound Insulation Materials(Gazi Univ, 2023) Koçyiğit, Filiz Bal; Köse, Ercan; Buluklu, Hatice Mehtap; Bal Kocyigit, FilizExperimental criteria for sound insulation material recommendation and design have an important share in indoor acoustic control. Among these criteria, laboratories with devices such as impedance tubes, alpha cabins and reverberation rooms used to measure and analyze parameters such as sound transmission loss and sound absorption coefficient have been investigated. In literature, it has been observed that there are studies on acoustic materials and the tests applied to these materials, but the application is more limited. According to research data, an Alpha Cabin model system design that can be used to develop new types of acoustic sound materials has been proposed. In addition to the fact that a large number of experimental measurements can be performed at lower costs using the designed Alpha Cabin model system, many tests can be performed easily for different material designs in a very short time. To perform these tests, the Alpha Cabin system has been designed based on noise and sound insulation. For example, floating flooring, ribbed connection, and so on. Afterward, different insulation materials were used for insulation purposes and standards were achieved. The Alpha Cabin test system, which was designed and developed, overlaps the experimental and theoretical data for 500, 2000, and 4000 Hz when compared with the values of 29.1 dB for 500 Hz, 38.6 dB for 2000 Hz, and 49 dB for 4000 Hz measured in the Acoustic Facade Panel Test Room, and it has been observed that it can be used in the development of new sound insulation materials.Article Assessment of the Acoustic Performance of Historical Structures That Shedlight on Today's Technologies: Fatih Pasha (kurşunlu) Mosque - Diyarbakır(2021) Aydın, Derya Çakır; Koçyiğit, Filiz Bal; Dalkılıç, NeslihanToday's technologies are produced using new construction methods and new materials and using differenttechniques. While the time dimension of the parametric design, which is defined as the fourth dimension,is sometimes an hour, day or year, sometimes this is seen as a bridge between the past and the present ofthe structures that have survived in a large date range. For this reason, the support of new buildingmaterials and techniques from time to time with methods that have the technical data of the periodobtained as a result of our historical heritage and long experience can provide us with new perspectives.The architectural features and construction techniques of historical mosques contain important data on theacoustic performance of religious buildings. Our heritage knowledge must be blended with newknowledge and technologies. Within the scope of the study, the details and systems that were effective inproviding acoustic performance parameters in the architecture of Fatih Pasha (Kurşunlu) Mosque, whichwas the first Ottoman period work of the city located in Diyarbakır Suriçi area, were examined. Among theobjective parameters of the sound, Reverberation Time (RT), Early Decay Time (EDT), Clarity (C80), andDefinition (D50) metrics were measured. The obtained data were compared with reference values andanalyzed. As a result of the data and analysis obtained in the literature reviews, it was determined that theacoustic values of the mosque were in harmony with the reference values. When the measurement datawere compared with the obtained international publications, it has been observed that the sound pressurevalue ranges depending on the frequency of acceptable indoor acoustics standards. The importance ofrestoration works in harmony with materials such as basalt, brick, limestone, lime mortar and plasterwhich are the original materials of the building was highlighted in terms of acoustics.
