Türkiye’de hacimsel ısıtma, binalarda enerji tüketiminin ana kalemidir. Özellikle erken tasarım süreçlerinde yapılacak etkin kabuk yalıtımı, binanın yıllık ısıtma enerjisi ihtiyacını ciddi oranda azaltan en yaygın pasif çözümdür. Bu çalışma, tüm Türkiye için binalarda erken tasarım aşamasında yapılacak ek kabuk yalıtımı yatırımlarının etkinliğini değerlendirmeyi amaçlar. Çalışma, TS 825 “ Binalarda ısı yalıtım kuralları” standardının yürürlükteki (2008) ve taslak halindeki (2013) versiyonlarını esas alır. Çalışmada, yalıtımsız bir binanın TS 825’e göre yalıtılmasının etkinliği kısa dönem (yıllık ısıtma enerji ihtiyacında sağlanan tasarruf, ek yalıtım maliyeti ve ek sera gazı salımı) ve yaşam döngüsü (yaşam döngüsü maliyeti ve sera gazı salımı) olmak üzere iki farklı süreçte incelenmiştir. Ayrıca yapılan ek yatırımın, maliyet ve sera gazı açısından geri ödeme süreleri de analiz edilmiştir. Analizler, standarda göre yapılan yalıtımların yıllık ısıtma enerjisi ihtiyacında %75’lere, yaşam döngüsü maliyetinde %70’lere, yaşam döngüsü sera gazı salımında ise %73’lere varan iyileştirmeler sağladığını göstermiştir. Maliyet geri ödeme süreleri 7 yılın, sera gazı geri ödeme süreleri ise 2 yılın altında hesaplanmıştır.
Volume heating in Turkey is the main pen for energy consumption in buildings. In particular in early design processes, effective coal isolation is the most common passive solution that significantly reduces the building’s annual heating energy demand. This study aims to evaluate the effectiveness of additional coal insulation investments in the early design phase of the buildings for all Turkey. The study is based on the current (2008) and drafted (2013) versions of the TS 825 "Rules of Heat Isolation in Buildings" standard. In the study, the effectiveness of isolating an unisolated building according to TS 825 was studied in two different processes, short-term (saving in annual heating energy needs, additional isolation costs and additional greenhouse gas emissions) and life cycle (life cycle costs and greenhouse gas emissions). Additionally, the additional investment, cost and greenhouse gas reimbursement periods have also been analyzed. Analysis showed that standard-made isolations provide up to 75% of annual heating energy needs, up to 70% of life-cycle costs and up to 73% of life-cycle greenhouse gas emissions. Cost refund periods are calculated for 7 years, while greenhouse gas refund periods are calculated for less than 2 years.
Space heating is the dominant item of energy consumption of buildings in Turkey. Effective building envelope insulation, especially in early design phase, is the most common passive solution that significantly reduces the annual heating energy requirement of the building. This work aims to assess the effectiveness of additional envelope insulation investments at the early design phase of buildings for all cities in Turkey. The study utilizes the current (2008) and draft 2013 versions of the TS 825 standard "Thermal insulation requirements in buildings". In the study, the effectiveness of insulating an uninsulated building according to TS 825 has been investigated for two different time periods: short term (savings on annual heating energy requirement, additional insulation cost and additional greenhouse gas emissions), and life cycle (life cycle cost and greenhouse gas emissions). In addition, the cost and emission payback times have also been analyzed. Analyzes have shown that insulations based on the standard provides improvements of up to 75% for annual heating energy, 70% for lifecycle cost, and 73% for lifecycle greenhouse gas emissions. Payback periods are under 7 years for the cost and under 2 years for the greenhouse gas emissions.
