Article Citation - Scopus: 2Leed 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.

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.Article Citation - WoS: 115Citation - Scopus: 129A Comparative Review of Environmental Concern Prioritization: Leed Vs Other Major Certification Systems(Academic Press Ltd- Elsevier Science Ltd, 2015) Suzer, OzgeThe 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.
