Historically, natural ventilation has been an important factor to achieve thermal comfort and reduce energy consumption in healthcare buildings. Since the recent century, there has been an increasing change and scientific advancement that led to the reliance of mechanical ventilation systems in commercial buildings and especially in hospitals and healthcare settings. However, the fully mechanical system approaches have changed gradually after global warming and the lack of energy sources. In this context, this study investigated systematically, passive ventilation techniques used in medieval near eastern hospitals ”Bimaristans” and historical hospitals in Europe. The study traced the roots of natural ventilation in a sample of historical healthcare buildings. It also investigated ventilation techniques used in historical hospitals in Middle East and Europe. This study is looking forward to discover the architectural design parameters’ effects of historical hospitals on ventilation, to make a better environment for patients’ health by learning from past lessons in traditional architecture, and how could we adapt these techniques in our nowadays healthcare buildings. This step will allow further research on the adaption and integration of passive techniques inherited from the past in our contemporary hospital design.

In this study, the influence of architectural design parameters (the exterior window area, the wall height at a corridor-side, and the door gap of a toilet unit) on the airflow patterns and malodorous volatile substance (acetic acid) distributions within toilet units were investigated via computational fluid dynamics (CFD), with the restrooms in K–12 public schools (kindergarten through grade 12) of Taiwan as research objects. The results show that when there is a 2 m/s north wind in winter, all the cases exceed the required 12 air changes per hour (ACH), and most are above 43.75 ACH. When there is a 0.5 m/s south wind in summer, nearly half of the cases fail to reach 12 ACH. Maintaining an adequate natural ventilation rate and an acceptable level of odor pollution through passive design and architectural design is difficult. Thinking about how to improve the ventilation efficiency of toilet units with the aid of simple, appropriate, and energy-saving mechanical ventilation approaches is necessary.

Beyond being a shelter, houses are such structures which obtain meanings shaped by the influence of culture, particularly reflecting the society’s socio-cultural structure. As a time-khronos and space-topos pattern, the houses reflect the characteristics of the culture or ethnic group which they are part of, while on the other hand, they reflect the images of the individual’s essence as a communicative action. The effect of climate and typology, which are physical components of culture, as well as social components of culture, such as value systems, belief, lifestyle and habits, are cardinal factors in the formation of traditional houses. In this respect, traditional structures are visual representation spaces that narrates their own story, like verbal culture, and they convey their unique codes through visuality. This study, which discusses traditional architecture as a cultural text, aims to reveal traditional Urfa houses through analytical readings, within the context of visual semiology.. The samples selected within the scope of the study will be evaluated according to the context of stylistic features they are part of, such as plan and spatial perspective, the location of the houses, and detections regarding the visual culture will be discussed through the cultural and architectural design approach of Umberto Eco.

The paper focuses on the relationship between the architectural culture and architectural design, puts forward the concept of architectural culture, expounds architectural cultures influence on Chinese traditional architecture and the western traditional architectures, and summarizes the importance and influence of architectural culture in the modern architectural design. This paper provides reference and experience for architects to design the modern architecture that can embody the design and spirit more vividly.

The double-skin façade (DSF) is one of the most crucial paradigms of building envelope design in last decades. DSF prospects a unified architectural phenomenon based on comfort rank of building driven by the dogmas of aesthetic-glass façade and practical-natural ventilation aspirations. Therefore, the utilization of DSF has been the most prevalent catalyst for architectural design. The study discusses to structure a valid evaluation method focusing on DSF elements in order to fragment human comfort standards within asserting an accurate system in the preliminary design stage. The study significantly examines the tools/ways of integrating DSFs' human comfort parameters in contemporary architecture though a convincing design system. Apparently, the study aims to provide a proposed guideline within a established analyzing system for architects in order to better formation of DSF elements; which refers and promote the human comfort standards. The results demonstrate a modest insight on understanding the potentials of DSF elements in the early design stage significantly following defined architectural conceptions; cooling, lighting, thermal, acoustic and visual comfort intensity. Based on obtained data; study aims to enclose a diminutive knowledge or demonstration of how the concept might work for future development of contemporary architecture within DSF area.

Three Degrees Of Freedom

Abstract This paper presents a study of the architecture optimization of a three-degree-of-freedom parallel mechanism intended for use as a telescope mirror focussing device. The construction of the mechanism is first described. Since the mechanism has only three degrees of freedom, constraint equations describing the inter-relationship between the six Cartesian coordinates are given. These constraints allow us to define the parasitic motions and, if incorporated into the kinematics model, a constrained Jacobian matrix can be obtained. This Jacobian matrix is then used to define a dexterity measure. The parasitic motions and dexterity are then used as objective functions for the optimizations routines and from which the optimal architectural design parameters are obtained.
