A Parametric Model Proposal for Energy-Efficient Building Design in the Cold-Arid Climate Region: A Case on Tabriz

Abstract

Built environments are responsible for significant global energy consumption, greenhouse gas emissions, and environmental problems. Due to the rapid increase in the population in cities, the unplanned construction of the housing need has a share that must be addressed in the emergence of these problems. Therefore, today, the energy-efficient design of new settlements has become a current and essential approach. It has made it necessary to consider the decisions taken regarding the factors affecting building energy consumption before the design. In this direction, the effects of design parameters such as window ratio, balcony depth, material type, material color, insulation used, number of floors, basement floor usage, aspect ratio, and building orientation status on energy performance in the city of Tabriz with a cold-arid climate were analyzed with the Design-Builder program. Then, suitable criteria to reduce energy consumption were searched. By comparing the results obtained from the analyses, the effect of the appropriate architectural decisions regarding these parameters on energy saving has been determined, a guide for designing energy-efficient buildings has been created, and a model proposal has been provided.

Soğuk-Kurak İklim Bölgesinde Enerji Etkin Bina Tasarımı için Parametrik bir Model Önerisi: Tebriz Örneği

Abstract

Kentsel yerleşmeler, küresel enerji tüketiminin, sera gazı emisyonlarının ve çevresel sorunların önemli bölümlerinden sorumludurlar. Kentlerde, nüfusun hızla artışı nedeniyle konut ihtiyacının plansız yapılaşmaları bu sorunların ortaya çıkmasında göz ardı edilemeyecek paya sahiptir. Bu nedenle günümüzde, yeni geliştirilecek yerleşmelerin enerji etkin olarak tasarlanması artık güncel ve önemli bir yaklaşım haline gelmiştir. Bu da, tasarım öncesi bina enerji tüketim miktarını etkileyen faktörlerle ilgili alınan kararların dikkate alınmasını zorunlu kılmıştır. Bu doğrultuda, çalışmada soğuk-kurak iklime sahip Tebriz kentinde pencere oranı, balkon derinliği, malzeme türü, malzeme rengi, yalıtım kullanımı, kat sayısı, bodrum kat kullanımı, en boy oranı ve bina yönlendiriliş durumu gibi tasarım parametrelerinin enerji performansına etkileri Design Builder programı ile analiz edilmiş, enerji tüketimini düşürmek için uygun kriterler araştırılmıştır. Analizlerden elde edilen sonuçların karşılaştırılması ile bu parametrelere ilişkin uygun mimari kararların enerji tasarrufundaki etkisi çıkarılmış ve enerji performanslı bina tasarımına yönelik bir kılavuz oluşturulmuştur. En son aşamada, elde edilen kılavuz sayesinde bir model önerisi de sunulmuştur.
