“…Artan talebi karşılamanın en kolay yollarından biri fosil yakıt kaynaklarını kullanmaktır. Bununla birlikte, fosil yakıtların sınırlı miktarı, enerji fiyatının artması, çevre sorunları ve küresel ısınma gibi nedenlerle enerjinin etkin kullanımı önemli hale gelmiştir [1], [2]. Ülkemizde birincil enerji kaynakları tüketiminde petrol, 2008 yılına kadar ilk sırada yer alırken, artık yerini doğal gaza bırakmıştır.…”

Binalarda kullanılan enerji tüketiminin yaklaşık olarak %70-80'i ısıtma, soğutma ve sıcak su üretimi amaçlıdır. Binalarda enerji tasarrufu için alınabilecek başlıca önlemlerden birisi ısı yalıtımıdır. Bu çalışmada Denizli ili için kış aylarında binaların ısıtılması ve yaz aylarında soğutulmasında enerji tasarrufu için farklı yakıt türlerinde optimum izolasyon kalınlıkları arasındaki en ekonomik kombinasyonun belirlenmesinde farklı izolasyon malzemeleri ve CO2 emisyonları dikkate alınarak karşılaştırmalı bir çalışma sunulmuştur. Bu amaçla derece-saat yöntemi ve ömür maliyet analizi kullanılmıştır. Hesaplamalar dört farklı yalıtım malzemesi ve iki farklı yakıt için yapılmıştır. Çalışmada maliyeti minimum yapan optimum izolasyon kalınlığı, Denizli ili için kış aylarında ısıtma için 0.012-0.031 m, yaz aylarında soğutma için ise 0.009-0.022 m arasında değişmektedir. CO2 emisyonu, artan yalıtım kalınlığı ile logaritmik olarak düşmektedir. Belirlenen koşullar için enerji tasarrufunda %22-24'lük farkla izolasyon malzemesi olarak camyünü uygunken, CO2 emisyonu azlığı bakımından %10-34'lük farkla poliüretan daha uygundur. Enerji tasarrufu dikkate alındığında kömür doğalgaza göre yaklaşık %9-11 arasında daha ekonomiktir. Çevre etkisi açısından ise doğalgaz, kömür ile ısıtmaya göre, %37-40 oranında CO2 emisyonu azlığı ile tercih edilebilir. Denizli ilinde CO2 emisyonu için en düşük değerler, poliüretan yalıtım malzemesi ile kaplı, ısıtma kaynağı olarak doğalgaz kullanılan binada elde edilmektedir. Approximately 70-80% of the buildings' energy consumption is for heating, cooling, and hot water production. One of the main measures that can be taken to save energy in buildings is thermal insulation. In this study, a comparative study is presented by considering different insulation materials and CO2 emissions to determine the most economical combination between the optimum insulation thicknesses of different fuel types for heating and cooling of buildings in the Denizli province. For this purpose, a degree-hour method and life cost analysis is used. Calculations are made for four different insulating materials and two different fuels. The optimum insulation thickness, which minimizes the study's cost, varied between 0.012-0.031 m for heating in winter and 0.009-0.022 m for cooling in summer. CO2 emissions are decreasing logarithmically with increasing insulation thickness. Under specified conditions, glass wool is more suitable with a 22-24% difference in energy saving; polyurethane is more suitable with a 10-34% difference in terms of low CO2 emissions. While considering energy saving, coal is more economical between 9-11% compared to natural gas. Natural gas could be preferred with 37-40% CO2 emission reduction compared to heating with coal in terms of environmental impact. The lowest values for CO2 emission in the Denizli province are obtained in the building covered with polyurethane insulation material.

“…Also, Dombaycı [18] investigated the environmental impact of optimum insulation layer thickness for the best insulation material (expanded polystyrene) and fuel type (coal) and found that the reduction in CO 2 emission is 41.5%. Then, Dombaycı et al [32] examined the optimum insulation layer thickness with economic and environmental analysis for Aydın, Samsun, Eskişehir, Ardahan, which are located in four different climate zones of Turkey. The authors selected expanded polystyrene and polyurethane as insulation materials, coal and natural gas as fuel types.…”

This study determines the optimum insulation layer thickness to be applied to external building walls considering the heating degree-day (HDD) method, then energy saving costs, payback periods, and carbon dioxide (CO 2 ) emissions are calculated accordingly. The optimisation analysis is performed for four different thermal insulation materials (glass wool, rock wool, extruded polystyrene, and expanded polystyrene). Natural gas is chosen as fuel for heating purposes, and horizontal perforated brick is preferred in the wall. One of the original features in this study is environmental analysis to determine the CO 2 emission for the insulated wall in Turkey provinces. Another feature is that it has the most up-to-date data about HDD values and fuel and insulation material costs. The worst and best insulation materials are obtained as rock wool and glass wool, respectively. The optimum insulation layer thickness for the best case is varied between 0.07 m and 0.23 m, depending on the HDD values of provinces. The annual total energy saving cost is in the range of 4.4-53.5 $/(m 2 year), and the payback period is 0.11-0.38 years. Besides, the reduction in annual CO 2 emission is changed between 53.2% and 94% for the best case, compared to the uninsulated wall.

Optimum Insulation Thickness for Building Exterior Walls in 32 Regions of China to Save Energy and Reduce CO2 Emissions

China accounts for approximately 30% of the CO 2 emissions-one of the largest proportions from a single nation. Therefore, reducing the CO 2 emissions in China will play a decisive role in global CO 2 emissions reduction. This paper is a proposal of optimum insulation thickness (OIT) for the exterior walls of buildings in 32 regions of China to save energy and reduce CO 2 emissions. The determination of the OIT for exterior walls its impact on the annual total energy cost and annual CO 2 emissions per unit area of building exterior walls were calculated for 32 regions of China using the life-cycle cost analysis (LCCA) and degree-days (DD) method. The results indicate that the annual total energy cost decreases up to the OIT level, and increases beyond the OIT level. The annual CO 2 emissions can be reduced by increasing the insulation thickness. It is predicted that the average total energy cost of 32 regions can potentially be decreased by about $5/m 2 -year (40%) and the average CO 2 emissions of the 32 regions can potentially be reduced by about 27 kg/m 2 -year (63%) when the OIT is applied. It also shows it is more effective to apply the OIT for the exterior walls of buildings to save annual total energy cost and reduce annual CO 2 emissions in the Severe Cold and Hot Summer & Cold Winter climatic zones rather than the other climatic zones of China.
