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; 27418; 01. Çankaya Üniversitesi; 05. Mimarlık Fakültesi; 05.01. İç Mimarlık
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.

A Comparative Review of Environmental Concern Prioritization: Leed Vs Other Major Certification Systems
(Academic Press Ltd- Elsevier Science Ltd, 2015) Suzer, Ozge; 27418; 01. Çankaya Üniversitesi; 05. Mimarlık Fakültesi; 05.01. İç Mimarlık
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.

PurposeGreen buildings which provide improved user health conditions and environmentallyresponsibleapplicationshavegainedsignificantattention, due to the increasing environmental problems, particularly causedbytheconstructionindustryattheglobalscale.However,vegetation is still not sufficiently integrated into buildings, even though numerous benefits of plants have been proven by many studies in literature.Thisresearchaimstofindouttheopinionsofprofessionalsandacademiciansinarchitecture-relatedfieldsregardingthecriticalaspects,aswellasthemotivatorsandbarriersfacedinBIVapplications, namely; green roofs, green walls and interior gardens. Hence, it strives to help increase their application rates by underlining the significant issues to be considered.Design/methodology/approachAs to fulfilling these objectives, a questionnaire survey was conducted on120participantswithvaryingprofessionsincludingarchitects,landscape designers and civil engineers, from four countries.FindingsThe results of this study pointed out that, healthcare buildings were given the first priority among the building types for applying BIV. Moreover, among the motivator factors, receiving a certificate was found as an important incentive, besides the environmental, social and economicbenefitsofBIV.Furthermore,althoughthehighlyratedbarriers were found as ‘the lack of proper regulations’ and ‘lack of demandbytheuser/client’,thefindingsshowedthatthehighestresponsibility for the implementation of these applications was placed on the architect.Research Limitations/Implications Based on the five major groups of Köppen climate classification system, the case countries were selected as one from each of the four main types,andbyneglectingonlyPolar,asitlackssettlements.Byconsideringdiverselevelsofdevelopmentandeconomicwelfare,countries were selected as; Canada (Snow: Humid-Subarctic), Libya (Dry:Desert-arid),Malaysia(Tropical:Tropical-Rainforest)andTurkey (Mild temperate: Mediterranean).Sincethestudycoveredfourdifferentcountries,thesurveywasconducted by the use of Google Forms software program. This tool enabled the production and distribution of questionnaires, as well as thecollectionofdatabasedontheresponsesoftheparticipants.Furthermore, in order to provide consistency among the questionnaires applied in different countries, the survey was conducted in English language, although it was not the native language for a majority of the participants. Moreover,basedonstudiesclaimingthatparticipantsaremoreinclined to select the option with the mid-value in a Likert scale, which implies a neutral position, in the questionnaire, these types of questions were constructed with the forced choice method, by keeping the scales with even number of options.Practical ImplicationsIt is expected that the results of this study would be beneficial to both the academicians and professionals involved in the green building industry,aswellastothegovernmentaland/orgreenbuildingauthorities. It is expected that this study will help serve as a guide for thestakeholderstoincreasetheapplicationratesofBIVintheconstruction industry.Social ImplicationsThe results of this study were also evaluated based on the findings of four case countries and certain conclusions were derived as to their underlying socio-economic and geographical reasons.Originality/value - Althoughstudiesonsimilarsubjectshaveappeared in the literature, there are none which solely focuses on BIV applicationsbyconductingasurveyonthementionedfourcasecountries and compares its findings with the literature and presents an in-depth analysis on the issue.
Karma Kullanımlı Çok Katlı Konut Yapıları Üzerine Bir Analiz:Yeşil Bina Değerlendirme Kategorileri Bazında Üç Vaka Etüdü
(2020) Suzer, Ozge; Yılmaz, Meltem; 27418; 01. Çankaya Üniversitesi; 05. Mimarlık Fakültesi; 05.01. İç Mimarlık
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.
