Dünyadaki enerji tüketiminin %50’si ve fosil yakıt tüketiminin %40’ı yapı yaşam döngüsü süreçlerinde ortaya çıkmaktadır. Aynı zamanda bu süreçler, sera gazı etkisi oluşturan maddelerin salınımının %50’sini ve toplam hava kirliliğinin %24’ünü oluşturmaktadır. Bu anlamda, yapıların enerji ve atmosfer ile olan ilişkileri, tüm canlılar için hayati bir önem taşımaktadır. Dünyada birçok disiplin, çevresel sorunların azaltılması konusunda çalışmalar yürütmektedir. Bu çalışmaların bir neticesi olarak ortaya çıkan sürdürülebilirlik ve sürdürülebilir mimarlık kavramı, yapı sektörünün çevresel etkilerinin tartışılmasına olanak sağlamıştır. Bu kapsamda, mimari ürünlerin sürdürülebilirlik düzeylerinin ölçülmesini hedefleyen çeşitli sertifikalandırma sistemleri geliştirilmiştir. Bu sistemlerden biri olan ve ülkemizde de yaygın olarak kullanılan LEED yeşil bina sertifikalandırma sistemi, puanlama sisteminde Enerji ve Atmosfer kriterine büyük bir pay ayırmıştır. Çalışmanın amacı Maslak’taki LEED sertifikalı ofis yapılarının Enerji ve Atmosfer kriteri bakımından sahip oldukları güçlü ve zayıf yönleri ortaya koyarak durum analizi yapmak ve iyileştirici-geliştirici önerilerde bulunmaktır. Bu kapsamda Alsar Maslak No:1, Orjin Maslak, Maslak Link Plaza, Olive Plaza ve Uniq İstanbul projeleri ‘Enerji Performansının Optimize Edilmesi’, ‘Yerinde Yenilenebilir Enerji Kullanımı’, ‘Gelişmiş Yapılandırma’, ‘Gelişmiş Soğutma Yönetimi’, ‘Ölçüm ve Onaylama (Temel Bina-Kiracı Alt Ölçümü)’ ve ‘Yeşil Güç’ açısından değerlendirilmiştir. Elde edilen bulgularda Enerji ve Atmosfer kriteri açısından Orjin Maslak Binasının en yüksek puanı (18/37), Olive Plaza’nın ise en düşük puanı (8/37) aldığı görülmüştür. Diğer üç bina 37 üzerinden 16 puan alarak aynı performansı sergilemişlerdir. Tüm bina ortalamaları üzerinden ele alındığında ise ‘Gelişmiş Soğutma Yönetimi’ ve ‘Ölçüm ve Onaylama (Temel Bina - Kiracı Alt Ölçümü)’ kredilerinde %80 ile en başarılı olunduğu, daha sonra %60 ile ‘Gelişmiş Yapılandırma’ kredisinin yerine getirildiği görülmüştür. ‘Enerji Performansının Optimize Edilmesi (%34)’ ve ‘Yeşil Güç (%20)’ kredilerinde istenilen performansın elde edilemediği ‘Yerinde Yenilenebilir Enerji’ kriterinin ise hiç kullanılmadığı ortaya konmuştur.
50% of the energy consumption in the world and 40% of the fossil fuel consumption occurs in the processes of the building life cycle. At the same time, these processes account for 50% of the emissions of the greenhouse gas effects and 24% of the total air pollution. In this sense, the relations of structures with energy and atmosphere are vital to all living beings. Many disciplines around the world are working on the reduction of environmental problems. The concept of sustainability and sustainable architecture that emerged as a result of these studies has made it possible to discuss the environmental impacts of the construction sector. In this context, various certification systems have been developed to measure the sustainability levels of architectural products. The LEED green building certification system, which is one of these systems and is widely used in our country, has given a large share to the Energy and Atmosphere criteria in the rating system. The purpose of the study is to analyze the situation by revealing the strengths and weaknesses of the LEED-certified office structures in Maslak in terms of Energy and Atmosphere criteria and to make healing-developing recommendations. In this context, Alsar Maslak No:1, Orjin Maslak, Maslak Link Plaza, Olive Plaza and Uniq Istanbul projects have been evaluated in terms of ‘Energy Performance Optimization’, ‘Renewable Energy Use in the Site’, ‘Advanced Structure’, ‘Advanced Cold Management’, ‘Metery and Approval (Basic Building-Rental Sub-Metery)’ and ‘Green Power’. The findings found that in terms of Energy and Atmosphere criteria, Orjin Maslak Building received the highest score (18/37), while Olive Plaza received the lowest score (8/37). The other three buildings have shown the same performance by taking 16 points out of 37. When dealt with all the buildings on average, it was seen that the "Advanced Cold Management" and "Metery and Approval (Basic Building - Rental Sub-Metery)" credits were the most successful with 80%, then the "Advanced Structure" credits were fulfilled with 60%. The “Energy Performance Optimization (34)” and “Green Power (20%)” credits have not achieved the desired performance, but the “Renewable Energy” criterion has never been used.

In this context, Alsar Maslak No: 1, Orjin Maslak, Maslak Link Plaza, Olive Plaza, and Uniq Istanbul projects have been evaluated in terms of 'Optimize Energy Performance', 'On-Site Renewable Energy', ‘Enhanced Commissioning', 'Enhanced Refrigerant Mgmt', 'Measurement and Verification (Base Building- Tenant Submetering)' and 'Green Power'. In the findings obtained, it was seen that Orjin Maslak Building received the highest score (18/37) and Olive Plaza received the lowest score (8/37) in terms of Energy and Atmosphere criteria. The other three buildings scored 16 out of 37, performing the same. Considering all the building averages, it is seen that the ‘Enhanced Refrigerant Mgmt' and 'Measurement and Verification (Base Building- Tenant Submetering)' credits are the most successful with 80%, and then the ‘Enhanced Commissioning’ loan is fulfilled with 60%. It has been revealed that the desired performance could not be achieved in "Optimize Energy Performance (34%)" and "Green Power (20%)" and the 'On-Site Renewable Energy' criterion was never used.
