An analysis on mixed-use high-rise residential complexes in Istanbul as to their prioritization of evaluation categories in LEED
(Çankaya University Press, 2018) Süzer, Özge; Yılmaz, Meltem
The most globally used environmental assessment tool; LEED, offers the certification of projects according to the evaluation criteria of green buildings. Furthermore, emerging mixed-use high-rise residential complexes (MHRC) in metropolitans like Istanbul draw attention, as they help reduce carbon emissions by providing various facilities in one entity for its residents. Yet, they also have negative effects on resources, due to excessive energy consumptions owing to their high user capacities. The objective of this study is to analyse LEED certified MHRC in Istanbul, regarding their prioritization of evaluation categories. LEED’s database revealed nine certified MHRC under the NC scheme. Based on their gained points, mean ranks ( ) of categories were calculated, which indicated the priorities given by this building typology in Istanbul. The obtained category priority order was then compared to the one implied by LEED’s assigned category weights. It was found that EA gained much lower attention than needed.

Analyzing the Compliance and Correlation of Leed and Breeam by Conducting a Criteria-Based Comparative Analysis and Evaluating Dual-Certified Projects
(Pergamon-elsevier Science Ltd, 2019) Suzer, Ozge
Certified green buildings are known to demonstrate high environmental performance; however, it is still not clear where they stand among each other, unless certified by the same body. This study aims to examine the compliance and correlation between the most prominent green building rating systems, LEED and BREEAM. It also estimates how a project would be graded by one system if already certified by the other. Regarding the methodology of the study, the intents of evaluation criteria in the latest versions for new constructions of LEED and BREEAM are analyzed. Commonly addressed and different concerns are determined, and the scales for assigning their award levels are compared. It is observed that they have a high level of compliance because 83% of the environmental concerns are commonly addressed issues. Moreover, it is derived that a dual-certified project aiming to achieve the same award level in both assessments has to display a better performance in BREEAM as it includes a higher number of concerns to be fulfilled. Based on the correlation analyses on twenty dual-certified buildings, the results from the scatter plot diagram, Pearson's Correlation Coefficient (r) and Paired Samples t-Test show that there is a large positive linear correlation and that LEED scores are significantly higher than BREEAM scores. Furthermore, the difference between the averages of LEED and BREEAM scores and the average difference between award levels indicate that if there would be a difference in ratings of dual-certified projects, it would be in favor of LEED by one award level.

Leed Certified Mixed-Use Residential Buildings in Istanbul: a Study on Category-Based Performances
(Istanbul Teknik Universitesi, Faculty of Architecture, 2021) Süzer, O.
The building industry has a significant negative effect on climate change and increases other environmental problems at the global scale. LEED, which is one of the most globally used environmental assessment tool, provides the certification of projects according to the evaluation criteria of green buildings under certain categories. On the other hand, an emerging form of architecture, the mixed-use residential high-rise building (MRB), appears in larger numbers especially in the metropolitans of developing countries, such as Istanbul. This building typology displays a positive approach in the context of sustainability. Since they are high-budget projects addressing to high-income groups, it is inherently expected that they have a green approach as a social responsibility. The objective of this study is to analyze LEED certified MRBs in Istanbul by focusing on their prioritization of evaluation categories. LEED’s database revealed a total of twenty-one certified projects under the New Constructions (v.3) scheme. Based on the gained points by these projects, mean rank values of the evaluation categories were calculated, which indicated the priorities given by this sample group. Furthermore, the conducted Kruskal-Wallis test showed there was highly significant difference among the rankings of the categories for these projects. Based on these rank order tests, obtained category priority order of MRBs was compared to the one implied by LEED’s assigned category weights. It was found that Energy and Atmosphere category gained much lower attention than required. Taking the results of the study into account, certain conclusions were drawn for this building type in Istanbul. © 2021, Istanbul Teknik Universitesi, Faculty of Architecture. All rights reserved.

A Comparative Review of Environmental Concern Prioritization: Leed Vs Other Major Certification Systems
(Academic Press Ltd- Elsevier Science Ltd, 2015) Suzer, Ozge
The matter of environmental concern prioritization integrated into globally used green building rating systems is a fundamental issue since it determines how the performance of a structure or development is reflected. Certain nationally-developed certification systems are used globally without being subjected to adjustments with respect to local geographical, cultural, economic and social parameters. This may lead to a situation where the results of an evaluation may not reflect the reality of the region and/or the site of construction. The main objective of this paper is to examine and underline the problems regarding the issue of weighting environmental concerns in the Leadership in Energy and Environmental Design (LEED) certification system, which is a US-originated but globally used assessment tool. The methodology of this study consists of; (i) an analysis of the approach of LEED in the New Construction and Major Renovations scheme in version 3 (LEED NC, v.3) and the Building Design and Construction scheme in version 4 (LEED BD + C, v.4), (ii) case studies in which regional priority credits (RPCs) set by LEED for four countries (Canada, Turkey, China and Egypt) are criticized with respect to countries' own local conditions, and, (iii) an analysis of the approaches of major environmental assessment tools, namely; BREEAM, SBTool, CASBEE and Green Star, in comparison to the approach in LEED, regarding the main issue of this paper. This work shows that, even in its latest version (v.4) LEED still displays some inadequacies and inconsistencies from the aspect of environmental concern prioritization and has not yet managed to incorporate a system which is more sensitive to this issue. This paper further outlines the differences and similarities between the approaches of the aforementioned major environmental assessment tools with respect to the issue of concern and the factors that should be integrated into future versions of LEED.

Motivators for Green Buildings: A Review
(2018) Akreim, Mohamed; Süzer, Özge
Motivators can be defined as specific catalysts that drive people to act in a certain way. These motivators are important for promoting green buildings and have a clear impact on decision-makers to adopt and implement the green building concept in architectural practice. This paper presents a comprehensive literature review to identify the important motivators for the adoption of green buildings among the stakeholders of the construction industry, the categorization and efficiency of green building motivators, and also the strategies for green building motivators. By reviewing 32 relevant studies conducted in different countries from 2008 to 2017, a total of 26 factors were identified as the main motivators to promote green buildings. These green building motivators were categorized into environmental, economic, and social motivators. With regard to efficiency, it was found that all green building motivators, whether environmental, economic or social are important for promoting green buildings and to determine a priority among these categories was not possible. The strategies for the adoption of green building motivators were also found. It is notable that the government has the greatest role to motivate stakeholders to adopt and implement the green building concept. The literature review of this study has a wide scope, covering most of the countries in the world, including developed and developing countries from the West to East. Hence, unlike most studies on the main issue of this paper that focus on a specific country or region, this in-depth research led to the development of a list of motivators for green buildings, derived from an extensive range of nations, which vary from environmental, economic, and social This paper is expected to provide valuable information for decision-makers in the construction industry, namely, governmental authorities, design teams, and owners of projects regarding what motivate people to help further promote green buildings. The findings may also be useful for researchers to pursue further analyses on similar topics.
Sürdürülebilir Mimarlığın Sosyo-Kültürel Boyutu Bağlamında İzmir Ticaret Odası Genel Merkez Binasının Değerlendirilmesi
(2020) Süzer, Özge
T Sürdürülebilirlik kavramı; çevresel, sosyo-kültürel ve ekonomik olmak üzere üç ana boyut içermektedir. Ancak birinci nesil yapı değerlendirme sistemlerinin, genellikle sosyo-kültürel ölçütleri göz ardı ederek yalnızca çevresel kriterleri kapsadıkları görülmektedir. Bu bağlamda söz konusu makalede İzmir Ticaret Odası Genel Merkez Binası sürdürülebilirliğin sosyo-kültürel boyutu altında irdelenmektedir. Yapı, aldığı LEED sertifikası ile yeşil bir binadır, ancak literatür taraması sonucunda belirlenen; “tarihi ve kültürel değerlerin korunması”, “sosyal eşitlik ve sosyal bütünleşme” ve “yaşam kalitesinin iyileştirilmesi” ölçütleri göz ardı edildiği için sürdürülebilir olarak tanımlanamamaktadır.
Karma Kullanımlı Çok Katlı Konut Yapıları Üzerine Bir Analiz:Yeşil Bina Değerlendirme Kategorileri Bazında Üç Vaka Etüdü
(2020) Suzer, Ozge; Yılmaz, Meltem
Bu makale, İstanbul’da yeşil iddiası olan üç adet karma kullanımlı çok katlı konut projesinin, LEED yeşil bina sertifika sisteminin değerlendirme kategorileri bazında analizini içermektedir. Çalışmada öncelikle LEED sistemi model alınmış ve bu yapı tipolojisi için uygun nitelikteki yeşil bina tasarım ölçütleri ışığında 53 sorudan oluşan bir ölçme-değerlendirme anketi hazırlanmıştır. Örnek projeler; yetkililerinin sorulara verdiği cevaplar, projelere ilişkin çizim ve sertifikalar ile yerinde gözlemler doğrultusunda değerlendirilmiştir. Anketi oluşturan sorular, LEED sistemi temel alınarak; beş ana kategori altında gruplanmıştır. Seçilen projelerin, bu kategoriler altındaki sorulara ilişkin olarak, gerçekleştirilmesi beklenen ölçütleri yerine getirip getiremediklerine göre, her kategoriye ait başarı yüzde oranları hesaplanmıştır. Bu bağlamda çalışmanın amacı, İstanbul’da bu yapı tipi için, hangi kategorilere öncelik verildiği ve hangilerinin ikinci planda kaldığını belirlemektir. Analiz edilen projelerin kategoriler bazında gösterdikleri başarı sıralaması ile LEED otoritelerince verilen önem sıralaması kıyaslanmıştır. Sonuç olarak, enerji kategorisine yeterince ağırlık verilmediği bulunmuş ve bu konuda dikkat edilmesi gereken hususlar ortaya konmuştur.
