Abstract

In the study, the energy consumption of buildings in five different cities in five climate zones according to TS 825, which is the Turkish insulation standard in buildings, and the life cycle of varying emission and pollutant types were investigated by an environmental impact assessment. In the study, Antalya from the first climate zone, Balıkesir from the second climate zone, Eskişehir from the third climate zone, Kayseri from the fourth climate zone and Kars from the fifth climate zone were selected for these climate zones. As energy sources for heating; natural gas, fuel oil, LPG, lignite coal, coke, hard coal and wood were accepted. According to ReCiPe midpoint environmental damage and impact categories were made for a total of twenty-four substances as the effect of eleven substances that affect global warming as emissions and thirteen substances that deplete ozone. Finally, evaluations were made according to the life-cycle emission effect depending on the selected cities, fuels and emission types for the ten and twenty-year lifetimes. As a result, the highest values were calculated for lignite coal, with 29138089840 ton for SF6, one of the substances that affect global warming, and 8929126304 ton for CFC-115, one of the substances that deplete the ozone layer, according to the amount of emissions and pollutants. The highest emission and pollutant potential was determined in lignite coal that one of the coal fuels. The lowest was found for natural gas fuel.

Çevresel Sürdürülebilirlik için Konutların Isıtma Enerji Tüketimlerine Bağlı Emisyonların Yaşam Çevrimi Çevresel Etki Değerlendirmesi ile İncelenmesi

Abstract

Çalışmada, binalarda Türk yalıtım standardı olan TS 825’e göre beş iklim bölgesinde bulunan beş farklı şehrindeki binaların enerji tüketimi ve buna bağlı farklı emisyon ve kirletici türlerinin yaşam çevrimi çevresel etki değerlendirmesi ile incelenmiştir. Çalışmada iklim bölgeleri için, birinci iklim bölgesini temsilen Antalya, ikinci iklim bölgesini temsilen Balıkesir, üçüncü iklim bölgesini temsilen Eskişehir, dördüncü iklim bölgesini temsilen Kayseri ve beşinci iklim bölgesini temsilen Kars şehirleri seçilmiştir. Konutun ısıtılması amacı için enerji kaynağı olarak; doğal gaz, Fuel-oil, LPG, linyit kömürü, kok kömürü, taş kömürü ve biokütle (odun) kabul edilmiştir. Çalışmada; ReCiPe orta nokta (midpoint) çevresel hasar ve etki kategorilerine göre on bir adet global ısınmaya etki eden madde ve on üç adet ozonu incelten madde etkisi olarak toplam yirmi dört adet madde için incelemeler yapılmıştır. Son olarak on ve yirmi yıllık ömürler için seçilen şehirler, yakıtlar ve emisyon türlerine bağlı yaşam çevrimi emisyon etkisine göre değerlendirmeler yapılmıştır. Sonuç olarak, emisyon ve kirletici miktarlarına göre, global ısınmayı etkileyen maddelerden SF6 için 29138089840 ton ve ozon tabakasını incelten maddelerden CFC-115 için 8929126304 ton ile Linyit kömüründe en yüksek değerler hesaplanmıştır. Emisyon ve kirletici potansiyeli en yüksek kömür yakıtlardan linyit kömüründe tespit edilmiştir. En düşük ise doğal gaz yakıtı için bulunmuştur.
