CASBEE

Neighbourhoods are increasingly gaining attention as planning units of great potential for contribution to sustainable development. Many assessment tools such as LEED-ND, BREEAM Communities and CASBEE-UD have been developed to examine the sustainability of neighbourhood development projects. Some of these tools are claimed to be suitable for assessment in different contexts, and LEED-ND has already been utilised in various countries. This study investigates the viability of using global standards through a series of comparative case studies. One certified case from each of the aforementioned tools is chosen and evaluated against its non-corresponding assessment tools. Selected cases are, respectively, Hoyt Yards, MediaCityUK and Koshigaya Lake Town. Results of this study provide evidence that casts doubt on the viability of using global standards. The paper concludes that neighbourhood sustainability assessment should be regarded as a pluralistic practice. This implies that any realistic and reliable assessment should take account of the specificities of specific locations and varying needs of different stakeholders.

Yeşil bina değerlendirme sistemleri, Türkiye’de son birkaç yılda gündeme gelmeye başlamış, hızla gelişmekte olan bir piyasaya sahip bir konudur. Şu anda Türkiye’nin yerel bir değerlendirme sistemi yoktur ve bina sahipleri, yabancı sistemleri kullanarak binalarını sertifikalandırmayı tercih etmektedirler. Değerlendirme sistemlerinin bilinirliğinin artması, yerel bir değerlendirme sisteminin ihtiyacının farkına varılmasını beraberinde getirmiştir. Bu doğrultuda ÇEDBİK, bir Türk yeşil bina değerlendirme sisteminin oluşturulması için çalışmalara başlamıştır.

Ülkeler, kendi değerlendirme sistemlerini geliştirirken tecrübeli olan diğer sistemlerden yararlanırlar. Pek çok ülkenin yeşil bina konseyi mevcut sistemleri inceleyip kendi yerel durumlarına adapte etmeyi tercih eder. ÇEDBİK de benzer bir yöntemle BRE Global-ÇEDBİK ortak adaptasyon çalışması ile BREEAM’i Türkiye koşullarına göre adapte ederek ulusal bir yeşil bina değerlendirme sistemi yaratmak hedeflenmektedir.

Bu çalışma, bahsi geçtiği üzere henüz oluşturulma aşamasında olan yerel bir değerlendirme sisteminin malzeme kategorisinde ele alınması gereken konuları belirlemeyi, bu konuların puanlamaya tabi tutulabilmesi için referans gösterilecek mevcut yasal dokümanları incelemeyi, eksik dokümanlara dikkat çekmeyi hedeflemektedir. Özellikle malzeme konusunun seçilme sebebi, yapı malzemelerinin binanın yaşam döngüsüne, hatta binanın inşa edilmesinden önceki zaman periyodlarına yayılan bir çevresel etki yaratmasıdır.

Bu inceleme çalışması için yalnızca BREEAM değil, LEED de kaynak olarak kullanılmıştır. Her iki sistemin malzeme kategorileri altında yer alan kredilerin yanısıra, yapı malzemeleriyle ilişkili olduğu düşünülen fakat farklı kategorilerde bulunan kriterler de incelenmiştir.

Çalışmanın sonunda, incelenen her iki sistemin güçlü ve zayıf yanları, BREEAM adaptasyonu ile sınırlı kalındığı takdirde Türk yeşil bina değerlendirme sisteminin malzeme kategorisinde oluşacak eksiklikler belirtilerek, konuyla ilgili alınabilecek önlemler önerilmiştir. Bu öneriler yapılırken, Türkiye’nin konularla ilgili mevcut yasal altyapısı göz önünde bulundurulmuştur.

"As the building blocks of cities, neighborhoods play a major role in helping to achieve global sustainability. In the past decade, several assessment tools worldwide have been developed to evaluate the effectiveness of the increasing number of neighborhood (re)development plans. While there is a plethora of research investigating various aspects of building assessment tools, until now little studies have looked at the empirical aspects of neighborhood sustainability assessment. To address this lacuna in literature, this study explores the uptake of sustainability criteria in projects certified under neighborhood sustainability assessment tools. In addition, it examines three cases from the US, the UK, and Japan that have been highly ranked under LEED-ND, BREEAM Communities, and CASBEE-UD, respectively. This is done through investigating compliance of each case with the principles of sustainable development. Furthermore, a series of comparative case studies are undertaken to evaluate each case using assessment tools other than the ones that have, in reality, been used for certifying the selected developments. In addition to highlighting strengths and weaknesses of each development, results show that social, economic, and institutional aspects are not adequately accounted for in theory and practice. Practice of neighborhood sustainability assessment is, to a large extent, market-driven and characterized by the dominance of the environmental aspects of sustainability. Also, results indicate that assessment tools can co-evolve through learning from their successes and failures. Results of this study can be used for optimizing the assessment tools.

Sustainable construction movement has been deeply transforming the traditional construction sector. As an important part of the sustainable construction delivery system, sustainable/green building rating systems play an essential role in implementing the sustainable principles into the construction industry and assessing the building’s rating. Most of the countries of the world have now developed their own rating systems. But as a matter of fact all the sustainability rating systems are not the same as they all provide different weightages to the assessment tools and even mention different assessment tools according to their available resources and regional location. Also each rating system has its own method of calculating weightages. For evaluation of buildings in Saudi Arabia the other rating systems cannot be used because for Saudi Arabia ‘water’is of major concern but the other rating systems provide very less weightage to it. Hence building rating system developed for any specific region becomes inappropriate for other regions. This paper makes detailed description and comparison among the mainstream green building rating systems and their common assessment tools. A short discussion about these sustainable/green building assessment tools has also been made, and it also briefly points out the importance and urgency of a separate sustainable rating system for Saudi Arabia and gulf region. New assessment tools and their weightages have been proposed in this paper for Saudi Arabia, which shall be very beneficial for the concerned authorities and shall help as guideline for the development of a separate rating system in the Gulf region.

Existing indicators for sustainable urban devel-opment do not identify the features of cities’ plan-ning structures and their architecture. This article tries to identify the most important sustainability rating systems for evaluating level of city' planning structure development.

Urban sustainability certification (USC) systems comprehensively assess and benchmark the sustainability of neighborhoods, communities, etc. However, it is important to understand what USCs mean by neighborhoods and communities in terms of definition and their certified developments' size. This study focuses on sustainable transportation and its measures in USCs in order to discern: how relevant are these measures to the varied local conditions, especially in developing countries? And whether they can generate palpable benefits vis-à-vis the certified developments' site areas. Taking descriptive analysis methods, this study focuses on four prominent USCs, namely, LEED for Neighborhood Development, BREEAM Communities, CASBEE for Urban Development, and The Pearl Community Rating System. The four USCs prescribed multiple measures for sustainable transportation, particularly in favor of active transportation and public transportation. However, the relatively small size of their ...
