A Study on 3D Modeling and Simulation of Sunshine Duration for Sustainable Buildings

Öz

Sunshine duration is an important meteorological parameter for sustainability studies in the fields of human health, agriculture, environment, ecosystem, climate change, architecture and solar energy. This parameter is a valuable data source for the analysis of the solar energy potential of urban buildings. Three-dimensional (3D) virtual building models provide more accurate and visually clear simulations by supporting solar energy studies in the urban planning process. In this study, a spatio-temporal analysis of the insolation time on the roof and facade surfaces of the building on the winter and summer solstice dates (December 21 and June 21) and the equinox dates (March 21 and September 23) was performed using a 3D virtual model of Tavşanlı Physical Therapy and Rehabilitation Hospital. Within the study area, it was determined that the longest insolation period occurred during the summer solstice, the shortest insolation period occurred during the winter solstice, and similar sunlight conditions were experienced during the spring and autumn equinoxes. The study contributes to broader goals such as sustainable urban planning and environmental protection by using advanced 3D simulation tools to guide future energy-saving designs in hospitals, a key component of public buildings.

Sürdürülebilir Binalar İçin Güneşlenme Süresinin 3B Modellenmesi ve Simülasyonu Üzerine Bir Araştırma

Öz

Güneşlenme süresi, insan sağlığı, tarım, çevre, ekosistem, iklim değişikliği, mimarlık ve güneş enerjisi alanındaki sürdürülebilirlik çalışmaları için önemli bir meteorolojik parametredir. Bu parametre, kentsel binaların güneş enerjisi potansiyelinin analizi için değerli bir veri kaynağıdır. Üç boyutlu (3B) sanal bina modelleri, kentsel planlama sürecinde güneş enerjisi çalışmalarını destekleyerek daha doğru ve görsel olarak net simülasyonlar sağlarlar. Bu çalışmada, Tavşanlı Fizik Tedavi ve Rehabilitasyon Hastanesi’nin 3B sanal modeli kullanılarak, kış ve yaz gündönümü (21 Aralık ve 21 Haziran) tarihleri ile ekinoks (21 Mart ve 23 Eylül) tarihlerinde binanın çatı ve cephe yüzeylerindeki güneşlenme süresinin mekânsal-zamansal analizi gerçekleştirilmiştir. Çalışma alanı içerisinde, en uzun güneşlenme süresinin yaz gündönümünde, en kısa güneşlenme süresinin kış gündönümünde gerçekleştiği, ilkbahar ve sonbahar ekinokslarında benzer güneş ışığı koşullarının yaşandığı tespit edilmiştir. Çalışma, kamu binalarının önemli bir bileşeni olan hastanelerde gelecekteki enerji tasarrufu tasarımlarına rehberlik etmek için gelişmiş 3B simülasyon araçlarını kullanarak sürdürülebilir kentsel planlama ve çevre koruma gibi daha geniş hedeflere katkıda bulunmaktadır.
