Abstract

Carbon dioxide emissions are one of the most important causes of global climate change. It is accepted in the world today that the world urgently needs to reduce carbon dioxide emissions in order to avoid the worst impacts of climate change. In this study, the optimum thickness of each insulation material is determined depending on the available costs and the total annual CO2 emissions of insulation materials for building external walls with different structure in the selected cities from different climate regions of Turkey. The different wall types insulated with four different insulation materials are presented. The results indicate that the optimum insulation thickness varies from 2.5 to 13 cm and is different for each wall type and insulation material. The total annual CO2 emission per unit area of the wall varies between 3.32 and 10.32 kg CO2/m2 depending on the insulation material and wall type.

TÜRKİYE'DE KONUTLARDA FARKLI DIŞ DUVAR YAPILARININ YILLIK CO2 EMİSYONLARI VE ENERJİ MALİYETLERİ

Abstract

Karbondioksit emisyonları, küresel iklim değişikliğinin en önemli nedenlerinden biridir. İklim değişikliğinin en kötü etkilerinden kaçınmak için dünyanın acilen karbondioksit emisyonlarını azaltması gerektiği bugün dünyada kabul görmektedir. Bu çalışmada, her bir yalıtım malzemesinin optimum kalınlığı, Türkiye'nin farklı iklim bölgelerinden seçilen şehirlerde farklı yapıya sahip dış duvarlar için yalıtım malzemelerinin mevcut maliyetlerine ve yıllık toplam CO2 emisyonlarına bağlı olarak belirlenmiştir. Dört farklı yalıtım malzemesi ile yalıtılmış farklı duvar tipleri sunulmaktadır. Sonuçlar, optimum yalıtım kalınlığının 2.5 ile 13 cm arasında değiştiğini ve her duvar tipi ve yalıtım malzemesi için farklı olduğunu göstermektedir. Duvarın birim alanı başına yıllık toplam CO2 emisyonu, yalıtım malzemesine ve duvar tipine bağlı olarak 3.32 ile 10.32 kg CO2/m2 arasında değişmektedir.
