Özet:

 Determining and analyzing the adverse consequences of construction works on the environment is an important research area. The necessity of execution of a large number of work items for the construction of a building and the large number of building material options make it difficult to conduct embodied energy and carbon emission analyzes of building constructions. In this study, a framework system is developed to overcome the mentioned difficulties. Construction items of a typical single-story building that can be built in the rural region are arranged and different construction options are generated for the construction items. The amounts of material and construction equipment requirements for the unit construction item of all construction options are computed. Semantic relationships between the building elements and the construction alternatives are established so that the quantity values that may vary according to the selected work item can be calculated exactly. Cost, embodied energy and carbon emissions caused by the construction of the building are calculated by matching the quantity values with the unit construction item definitions. Moreover, the heat loss calculations of the building are carried out according to TS 825 and the energy consumption, carbon emission and cost that will occur as a result of the utilization of wood, coal, electric stove and air conditioner options as heating source during its 50 years of life cycle are calculated. In order to examine the effects of construction items on the embodied energy, carbon emission and cost, Monte Carlo simulation is implemented by forming the building with random selections for each construction item among the defined construction options with equal probability of selection. At the end of the simulation the total embodied energy, carbon emission and cost of both the construction and the utilization phases of the structure are calculated. In this manner, the average embodied energy, carbon emission and cost effect of each of the construction items on the structure are determined. Prepared embodied energy and carbon emission quantities of the construction items and the analysis results presented within this study have the potential to be beneficial to the researchers studying on green buildings.

 İnşaat işlerinin çevre üzerindeki olumsuz etkilerinin belirlenmesi ve analizi önemli bir araştırma alanıdır. Bir binanın inşası için çok sayıda iş kaleminin uygulanması gerekliliği ve yapı malzemesi seçeneklerinin çok sayıda olması bina inşaatlarının gömülü enerji ve karbon salınımı analizlerinin yapılmasını zorlaştırmaktadır. Belirtilen zorluğun aşılması için bu çalışmada çerçeve bir sistem geliştirilmiştir. Kırsal alanda inşa edilebilecek tek katlı tipik bir yapının inşaat kalemleri belirlenerek farklı yapım seçenekleri hazırlanmıştır. Tüm yapım seçeneklerinin birim iş miktarı için gereken malzeme miktarları, iş makinesi kullanımı ve enerji gereksinimi belirlenmiştir. Seçilen iş kalemine göre değişebilecek metraj değerlerinin tam doğrulukta hesaplanabilmesi için yapı elemanları ve yapım alternatifleri arasında anlamsal ilişkiler kurulmuştur. Metraj değerleri ile birim iş tarifleri eşleştirilerek yapının inşasının neden olacağı maliyet, gömülü enerji ve karbon salınımı hesaplanmıştır. Ayrıca binanın ısı kaybı hesaplamaları TS 825e göre gerçekleştirilmiş ve 50 yıllık kullanımı boyunca odun, kömür, elektrik sobası veya klima ile ısıtılması sonucu oluşacak enerji tüketimi, karbon salınımı ve maliyet hesaplanmıştır. İnşaat kalemlerinin gömülü enerji, karbon salınımı ve maliyete etkisinin incelenmesi için Monte Carlo simülasyonu gerçekleştirilmiş ve tüm yapım seçeneklerinin eşit seçilme olasılığı olacak şekilde rastgele seçimlerle yapı oluşturulmuştur. Oluşturulan yapının inşası ve kullanımıyla ortaya çıkan gömülü enerji, karbon salınımı ve maliyet hesaplanmıştır. Bu şekilde inşaat kalemlerinin her birinin yapı üzerindeki ortalama gömülü enerji, karbon salınımı ve maliyet etkisi belirlenmiştir. Bu çalışma kapsamında hazırlanan ve sunulan inşaat işlerinin gömülü enerji ve karbon salınımı değerleri ile analiz sonuçları yeşil bina üzerinde çalışan araştırmacılara faydalı olma potansiyeline sahiptir.
