The design intent and the performance targets of projects may sometimes fail to match a building's actual post-occupancy performance. The mismatch of intended and actual building performance can be attributed to multifarious reasons. This study focuses on the role of project decisions made during design as one of the reasons of shortfall. The aim of the study is to unveil the design decision-making process of a state-of-the-art research building through the analysis of project's available set of IDP (Integrated Design Process) documentation. To understand the relationship and correlation between the energy performance gap and the decision-making process of the case building we investigated the design decisions' effect on the actual performance. The particular emphasis is on the decisions that were based on assumptions rather than measured actual test data for the proposed innovative building systems. The designed heat recovery system which was dependent on recovered heat from the neighboring research building had a significant effect on the building's poor energy performance. We investigated collected project data from coordination meetings thoroughly analyzed project documentation and quantified the building's actual energy performance data. The analysis of the project information shows the ripple effect of decisions that were made based on assumptions that triggered shortfalls in the building's overall actual performance. Our qualitative analysis indicates that the poor system performance during operations was related with the design decisions that were not based on the measurement of the actual performance of the existing systems in the neighboring building. The performance of the heat recovery from the neighboring building as a highly dependent Energy Conservation Measure (ECM) analyzed through collected documents and data. The ambiguity of the available heat potential from the neighboring building and related testing issues defined on an explanatory timeline of process coding. The conclusion includes recommendations for the design decision-making process for innovative system integrations for high-performance buildings and underlines the importance of IDP for complex buildings. © 2023 Elsevier B.V.

Covid-19 salgınının yayılmasını önlemek tedavi sürecini iyileştirmek için hastane içi dönüşümlere olan ilgi dünya çapında artmıştır. Covid-19’un son bulaşıcı sağlık tehdidi olduğu düşünülmediğinden mevcut hastane uyarlamalarını incelemek tedavi ve dinlenme alanları için gereksinime dayalı çeşitli planlama ve tasarım stratejileri geliştirme üzerine çalışmak büyük önem taşımaktadır. Bu çalışmada pandemi süreçlerinde hastane içi dönüşümlerde uygulanabilecek mekân içi planlama ve takiben mekanik havalandırma özelinde yapıcı önerilerde bulunabilmek amaçlanmıştır. Enfeksiyonun yayılmasını önlemek için hastane kılavuz şartnameleri ve literatürdeki çalışmalar incelenmiş hastane tasarımı üzerine uzmanlaşmış kişilerle çeşitli görüşmeler gerçekleştirilmiştir. Covid-19 sürecinde hastanelerde yapılan değişikliklerin analiz edilebilmesi içinse 35 hastane çalışanı ve 4 hastane yönetim personeliyle anket çalışması yapılmıştır. Veriler ışığında Türkiye’de üzerinde çalışılmış iki özel-hastaneden birinin tasarım planları ile hasta odalarının dönüşümünde uygulanabilecek adımlar alan çalışmasıyla aktarılmıştır. Hastane içi dönüşümlerde enfeksiyon kontrolünün sağlanabilmesi adına mekân planlaması (alanların ayrıştırılması/ dönüştürülmesi mekân içi zonlama) ve havalandırmanın (filtrasyon mekanik havalandırma için zonlama) uyum içinde olması gerektiğinden dönüşümlerin planlanması aşamasında disiplinlerarası çalışma yapılmıştır. Pandemi süreçlerinde enfeksiyonun yayılmasının önlenebilmesi için hastane dönüşüm uygulamalarının mekanik ve mimari planlamalarında tutarlılığın sağlanabilmesi adına öneriler geliştirilmiştir. Dönüşüm senaryoları Türkiye Cumhuriyeti Sağlık Bakanlığı kriterlerine uygun örnek bir özel-hastane odası üzerinden gerçekleştirildiği için diğer hastanelere de uyarlanabileceği sonuç bölümünde tip proje üzerinde havalandırma planları detaylandırılarak gösterilmiştir.

Evaluation and lessons learned from a campus as a living lab program to promote sustainable practices
(MDPI AG, 2021) Paul W. Save; Belgin Terim Cavka; Thomas M. Froese; Froese, Thomas; Save, Paul; Cavka, Belgin Terim
Any group that creates challenging goals also requires a strategy to achieve them and a process to review and improve this strategy over time. The University of British Columbia (UBC) set ambitious campus sustainability goals including a reduction in its greenhouse gas emissions to 33% below the 2007 level by 2015 and 100% by 2050 (UBC 2006). The University pursued these goals through a number of specific projects (such as major district energy upgrade and a bioenergy facility) and more generally through a “Campus as a Living Lab” (CLL) initiative to marry industry campus operations and research to drive innovative solutions. The CLL program has achieved significant successes while also demonstrating many opportunities for improvements and lessons learned. The aim of this study was to examine the UBC CLL program to identify and formalize its operations to extract key transferable characteristics and to propose replicable processes that other universities and municipalities can follow to expand their sustainable practices in similar ways. There was a learning curve with implementing a CLL program at UBC, thus the goal of this study was to potentially shorten this learning curve for others. The research involved an ethnographic approach in which researchers participated in the CLL process conducted qualitative analysis and captured the processes through a series of business process models. The research findings are shared in two parts: 1. generalized lessons learned through key transferrable characteristics, 2. a series of generic organizational charts and business process models (BPMs) culminated with learned strategies through defined processes that illustrate what was required to create a CLL program at UBC. A generalized future improvement plan for UBC CLL programs is defined generic BPMs about CLL projects are evaluated and the level of engagement of multiple stakeholders through phases of project life cycle given in the conclusion for future use of other Living Lab organizations. © 2021 Elsevier B.V.

Life cycle assessment of magnesium oxide structural insulated panels for a smart home in Vancouver
(ELSEVIER SCIENCE SA, 2018) Peixian Li; Thomas M. Froese; Belgin Terim Cavka; Froese, Thomas M.; Cavka, Belgin Terim; Li, Peixian
Two major trends are changing the face of the construction industry. Sustainability concerns are driving innovations to improve building's energy efficiency while advances in prefabrication are improving buildings' speed cost and quality. As new materials and techniques emerge their overall environmental impact must be evaluated using techniques such as life cycle assessment (LCA). This paper reports a life cycle assessment (LCA) of an innovative magnesium oxide structural insulated panel (MgO SIP) used for a high-performance smart home in Vancouver. The LCA compares the environmental impacts across six indicators for the MgO SIPs traditional SIPs and traditional stick-frame construction across the life cycle phases of raw material extraction manufacturing transportation construction and operation. The results show that the MgO SIPs do not outperform conventional alternatives notably due to the long-distance transportation of materials. However further LCA of hypothetical scenarios demonstrates that MgO SIPs have a great potential to become more environmentally friendly than the conventional alternatives by sourcing MgO domestically implementing local or onsite manufacturing and designing the MgO SIPs without oriented strand board. Although the results are context-dependent the investigation of hypothetical scenarios offers insight to improve the environmental performance of this innovative product. (C) 2018 Elsevier B.V.

Providing an Environmentally Responsible Design Experience in Architecture Education with the Integration of Multiple Courses: A Holistic Curriculum Study for Teaching on About and for Sustainable Development of the Built Environment
(Springer Science and Business Media Deutschland GmbH, 2025) Belgin Terim Cavka; Cavka, Belgin Terim
Sustainability is defined as the core subject of design education today where the effectiveness of environmental design approach on studio courses of architecture discipline is still questioned. Sustainability in higher education must be adapted to curriculums in an integrated approach to enable shared knowledge on the significant amount of core material of applied courses. Therefore better time management can be maintained through design education. Although the subject matter of integrated course structure is discussed in related literature with various different approaches (Celadyn World Trans Eng Technol Educ 15:317–322 2017a Glob J Eng Educ 19:207–212 2017b Sustain For 11(14):3820 2019 Sustain For 12(18):73832020, Steinø and Davidsen J Prob Base Learn High Edu 5(1):1–5 2017, Karlsi Procedia Soc. Behav Sci 106:1532–1539 2013, Domenica Iulo et al. Int J Sustain High Educ 14(4):434–448 2013, Gürel and Potthoff Int J Art Design Edu 25(2):217–230 2006, Gurel Int J Art Des Educ 29:184–199 2010, Hill J Int Des 33:37–52 2007, Fletcher and Dewberry Int J Sustain High Educ 3(1):38–47 2002) It is believed that the complex technical design and detailing requirements of sustainable projects can only be effectively taught through an integrated curriculum approach. Consequently incorporating multiple courses particularly those focused on environmental design and applied technical subjects into design studios is seen as a promising way to foster a cohesive and comprehensive sustainability mindset in the design of built environments. This chapter describes the construction of a holistic curriculum for the teaching on sustainable development of the built environment through the integration of multiple courses in the case of a medium-scale University curriculum. Since studio design courses are conducted by the integration of multiple courses effective time management is enabled through collaboration for different activities cultivated in different integrated courses. Integration will be analyzed through a multi-layer approach. © 2025 Elsevier B.V. All rights reserved.

The use of sun shading elements frequently seen in the residential tradition of the Aegean region. Controllable traditional venetian blinds (shutters) carried to the present through periodic changes are prominent design elements of the architectural heritage. This study aims to understand the effectiveness of these traditional sun control elements in terms of energy efficiency in the cooling season within three different locations (north mid and south Aegean coast) and daylighting illuminance level adaptations in Izmir mid Aegean coast area with 2 different materials and 3 different blind angles. To obtain data on-site measurements conducted in the field of interest. The sunshade illuminance level measurements of the studied residential example used as a source for more effective use of IES (VE) energy models before testing further variations. The main objective is to comprehend one of the traditional methods of coping with the effect of the sun and to understand the reasons from a technical point of view for future adaptations. As a result of the analysis carried out on the most critical days of sunlight the evaluation of solar shading elements in terms of daylighting balance and cooling loads in traditional houses will provide us the understanding of the effect of sun control variations in the defined temperate climate region. Tested methodology will guide future case studies. © 2023 Elsevier B.V. All rights reserved.
