Rapid advances in the capabilities of simulation tools and computer technologies have provided additional potential and choices for the designers and trainers. There are several kinds of simulation tools for energy efficiency and daylighting. During training practitioners, use some of them. This paper aims to discuss if there is any way to define and compare which one is appropriate for different stages of design process. Some of them are very complicated; on the other hand, some of them are much unsophisticated and not verified. The authors provide experiences of two workshops to show how the simulation tools successfully used to train the students. In addition, guidelines provided to maximize the usefulness of simulation for training student skills in sustainable design.

Günümüzde, teknolojinin ve sürdürülebilirlik olgusunun yaşam ve iş yapma biçimlerini değiştirmesiyle çalışma mekânları yeniden kurgulanmaktadır. Çalışma mekânlarının değişmesinde en etkili unsurlardan biri esneklik kavramıdır. Esnek çalışma mekânları çalışanların iletişimini kuvvetlendirecek ve yatay hiyerarşiyi destekleyecek şekilde tasarlanmaktadır. Esnek çalışma mekanlarında açık ofis alanları aktivite odaklı alanlarla desteklenmekte ve çalışanların konsantrasyon gerektiren çalışma, toplantı ve ekip çalışması gibi ihtiyaçlarını karşılayacak şekilde planlanmaktadır. Bu durumun bir göstergesi olarak günümüz bilgi ve teknoloji çağında organizasyonlar ofis olarak akıllı binaları ve esnek çalışma mekânlarını tercih etmeye başlamışlardır. Fiziksel çevre tasarımının çalışan memnuniyeti ve verimi üzerine etkileri bilindiğinden, bu yeni tip çalışma mekânları özelinde tasarımın ve çevre kalitesinin çalışan memnuniyeti, verimi ve yapılan işin kalitesine etkileri üzerine araştırmalar dünyada, özellikle Kuzey Amerika ve Avrupa'da hız kazanmıştır. Ancak, Türkiye'deki çalışma mekânları özelinde bu gibi çalışmalar sınırlıdır. Bu çalışmada, bu boşluğu doldurmak amacı ile İstanbul'da yer alan LEED sertifikalı bir binada hizmet veren bir firmanın esnek çalışma mekânı örnek olarak seçilmiştir. Anket, görüşme ve yerinde gözlem yöntemlerine dayanan bir kullanım sonrası değerlendirme çalışması yürütülmüştür. Elde edilen bulgular esnek çalışma düzeni, fiziksel çevre koşulları ve mekânsal tasarım bağlamında çalışan memnuniyetine etkileri açısından değerlendirilmiştir. Anahtar sözcükler: Akıllı bina; çalışan memnuniyeti; esnek çalışma mekânı; kullanım sonrası değerlendirme. Social, cultural, and economical structures shape physical work environments. Today, workplaces are reconstructed according to the effects of sustainability and technology on the form of working. Flexibility is one of the most influential elements affecting the change of workplaces. Flexible workplaces are designed to strengthen the communication and to support the horizontal organizational structure. Open office areas are planned to meet the need for activities such as relaxation, conversation, meeting, concentration, and teamwork. In the era of the knowledge society and technology, organizations increasingly prefer smart buildings and flexible workplaces as their work environments. As a result, there is a growing literature, especially in North America and northern Europe, on the impact of flexible workplace design and indoor quality on employee satisfaction, productivity, and work quality. However, such studies are still limited in Turkey. To fill the gap, this research focuses on a flexible workplace located in a LEED-certified building in Istanbul. A post-occupancy evaluation was conducted in this office. Data collection methods included questionnaires, interviews, and participant observations. The data was analyzed based on the employees' satisfaction from the flexible workplace.
A BIM-GIS integrated pre-retrofit model for building data mapping

Despite the many benefits associated with retrofit projects, they are still only slowly being implemented because of the many challenges that exist. One of these challenges is optimizing the decision between renovation scenarios based on economic and environmental goals, which can be made possible with an accurate pre-retrofit model. The intention of this paper is to introduce a pre-retrofit model that efficiently obtains and integrates multiple forms of building data as a critical step to develop a comprehensive understanding of a building to be renovated. Opportunities for utilizing building information modeling (BIM) and geographical information systems (GIS) for retrofitting projects were explored through the study of a historical campus building. With the use of as-is geometric data and as-is data, building data maps were obtained. The next step of this study is to use the model to conduct scenarios comparison and optimize renovation decision based on economic and environmental goals.

Considerable obstacles to implementing VR applications are associated with substantial time, and expense commitments; in addition to required skills in VR development using gaming authoring software. The overarching study suggests adopting an alternative approach to VR development. This paper focuses on the testing and validation of architectural VR applications. We present a systematic methodology for the evaluation of interactive VR systems, using established assessment methods and metrics, detailing user-testing procedures and providing qualitative and quantitative evidence, and relevant data analysis methods. The paper provides valuable insight into the design of the user studies and evaluation of interactive VR environments in architecture, enabling future research and informing design applications in a wider field.

This paper specifically focuses on a subset of 20 offices (n = 2133), identified from ranking 10 offices each, with the least (n = 1063) and highest (n = 1070) satisfaction scores, respectively. The satisfaction scores were evaluated on the basis of seven factors (i.e., building/office aesthetics and quality, thermal comfort and indoor air quality, noise distraction and privacy, personal control, connection to outdoor environment, maintenance and visual comfort, and individual space). Using the POE survey data from 20 offices, regression analyses and two-way ANOVA tests were carried out to understand the differences in occupants' satisfaction and perceived productivity arising from open-plan offices. According to the statistically significant regression analyses results, it was identified that building/office aesthetics and quality (β = 0.55, p < 0.001) and noise distraction and privacy (β = 0.33, p < 0.001) were the two strongest predictors contributing perceived productivity in low-performance offices. Two-way ANOVA test results for the 10 high-performance offices indicate that the perceived productivity was strongly associated with the office's physical configuration, the employees' working experience, and the working hours at that office.

Indoor mould is correlated to severe adverse health symptoms, such as severe allergic asthma, hypersensitivity pneumonitis and allergic alveolitis, allergic rhinitis and sinusitis. The issue is further magnified by the difficulty of detecting mould before it is fully germinated. Indeed, the visible manifestation happens only at the final proliferation stage, which usually starts

A multiple-tool POE approach with GIS-based spatial mapping method was used to analyze and visualize the survey results of building occupant satisfaction and the measured indoor environment quality. The occupants were overall satisfied with the indoor environment in their workspaces in the building of study, though thermal comfort was comparatively low with high percentage of occupants reporting their workspaces too cold. Air movement was found to be lower than preferred by the occupants, especially in interior offices where CO 2 level is also predominantly higher. Light levels in the building were found higher than preferred. Electric lighting power density installed did not reflect the fact that daylight is available for most of the lab and office spaces. Satisfaction with speech privacy was found lower in individual offices related to the construction detail of the connection between glazing curtain wall and interior walls. Linking performance outcomes with spatial information improves POE data management. Spatial mapping allows reasons that cause occupant discomfort and dissatisfactory measured performance to be identified more intuitively and makes it potentially easier to communicate POE results with architects, engineers and facility management professionals, to engaging them in the collaborative effort of continuous building performance improvement.
A review of the evolution of flexible learning environments in Australia: For a better match of primary school design and IEQ

Despite its penetration in the Australian public school sector, the interior design of FLEs hasn't been sufficiently investigated when it comes to Indoor Environmental Quality (IEQ) conditions provided within its open-plan configuration. FLEs' design typology creates the challenge of providing IEQ conditions that work for different zones used simultaneously by the mobile student population. In addition, current guidelines used in Australia are based on the traditional classroom with little, if at all, adaptations to FLEs' open-plan configuration and activity-based way of learning. By looking into the physical configuration of ten primary classrooms, this paper aims to identify potential shortcomings of the interior design FLEs along with a critical review of existing literature and existing NSW-state government guidelines. Results indicate that for a mobile cohort of occupying FLEs, there is a mismatch between IEQ conditions provided and the guidelines in use, as it tends to overlook students' non-stationary state and variety of activities, they are involved in. The adaptability of existing guidelines is therefore needed to better guide the design of Australian FLEs

Dış mekânlar, yerleşke kullanıcılarının toplumsal etkileşim, dinlenme ve rahatlama, rekreasyon, fikir alışverişinde bulunma ve güçlü bir mülkiyet ve aidiyet hissi oluşturma potansiyeli taşırlar. İnsanların birbirleriyle iletişim kurmalarını ve sosyalleşmelerini sağlayarak sosyal yaşam için ortak bir kimlik oluşturmak dış mekânların en önemli işlevidir. Ne var ki dış mekânlar ne kadar akılcı tasarlansa da, uygulamada beklenenin dışında bir kullanımla karşılaşılabilmektedir. Beklentiler ile uygulanan arasındaki farkın belirlenebilmesi için dış mekânlar ile bina grupları arasındaki ilişki, yeterlilik, kullanım süresi, erişilebilirlik ve fiziksel çevrenin etkileşimi bütünsel bir yaklaşımla incelenmelidir. Dış mekânlarda insan kullanımının ve tasarım niyetinin başarılı olup olmadığını değerlendirmenin en iyi yöntemlerinden biri olarak kullanım sonrası değerlendirme (KSD) önerilmektedir. Ne yazık ki, iç mekânların değerlendirilmesine ilişkin KSD yöntemleri hakkında çalışmalar her geçen gün artsa da, dış mekânların değerlendirilmesine yönelik özellikle üniversite yerleşkelerinde uygulanabilecek kapsamlı bir KSD çalışmasına rastlanmamaktadır. Bu çalışmada dış mekân kullanımını etkileyen değişkenleri ve bu değişkenler arasındaki etkileşimi bütüncül olarak ele alan bir KSD yöntemi tanıtılmıştır. Önerilen yöntem kent dışı bir üniversite yerleşkesinde uygulanmış ve uygulama sonuçları dış mekân kullanım değeri bakımından değerlendirilmiştir. Anahtar sözcükler: Dış mekan; kullanım sonrası değerlendirme; üniversite yerleşkesi; zaman-mekansal haritalama. Not only do university campuses consist of a variety of social and educational buildings, they also create an integrated system with their outdoor spaces and furniture, recreation and landscape areas. Outdoors have the potential to create social interaction, rest and relaxation, recreation, exchange of ideas and a strong sense of ownership and belonging. Creating a common identity for social life by enabling people to communicate and socialize with each other is the most important function of outdoor spaces. However, although the rationality of external spaces is designed, it is possible to use other than what is expected in practice. The relationship between the external spaces and the building groups, the adequacy, the duration of use, the accessibility and the interaction of the physical environment should be examined with a holistic approach to understand the difference between expectations and reality. In order to identify user needs in outdoor spaces as a way to assess if human use and design intentions are in fact successful, post occupancy evaluation (POE) is recommended as the most significant advanced method. Unfortunately, although studies on the evaluation of indoor spaces have been increasing day by day, there is no comprehensive study of POE that can be applied to the outdoor spaces, especially in university campuses. In this study, a POE method which discusses the variables that affect the use of outdoor space and the interaction between these variables is introduced. The proposed method was applied in a suburban university campus and the results were evaluated in terms of outdoor use.

An atrium is the social center of a building where people gather for social activities and also is a significant element of passive building systems if designed properly to provide user requirements. Estimation of energy use and thermal performance is difficult because of the complex thermal phenomena occurred at the atrium space due to its large size and high solar gains through the fenestration. It is not easy to obtain comprehensive results for evaluating the performance of the atrium building with a single simulation program. This paper introduces a performance based model for energy use and user comfort evaluation of atrium buildings with the use of multiple building performance simulation tools; Window 5.2, EnergyPlus, Comis, Delight, Gambit and Fluent and the resulting outputs which support the methodology.
