Virtual reality (VR) has been proposed for various purposes such as design studies, presentation, simulation and communication in the field of computer-aided architectural design. This paper explores new roles for VR; in particular, we propose rendering methods that consist of post-processing rendering, segmentation rendering and shadow-casting rendering for more-versatile approaches in the use of data. We focus on the creation of a dataset of annotated images, composed of paired foreground-background and semantic-relevant images, in addition to traditional immersive rendering for training deep learning neural networks and analysing landscapes. We also develop a camera velocity rendering method using a customised segmentation rendering technique that calculates the linear and angular velocities of the virtual camera within the VR space at each frame and overlays a colour on the screen according to the velocity value. Using this velocity information, developers of VR applications can improve the animation path within the VR space and prevent VR sickness. We successfully applied the developed methods to urban design and a design project for a building complex. In conclusion, the proposed method was evaluated to be both feasible and effective.

However, there is no comprehensive study about the practical use of this technology in the urban design field. The aim of this chapter is to investigate this subject. The first step is to outline the 3D digital models discussed as a context for the formation of virtual reality. Then summarizing experts view in the field of virtual reality technology; the study presents components, conditions and requirements necessary to create a virtual environment in its real scientific sense. Since the chapter aims at utilizing virtual reality in the context of urban design studies, it focuses on virtual reality applications in urban design projects, and advantages and limitations of this technique in this area. Finally, at the end of this chapter most common devices needed for equipping a VR Lab and experiencing the sense of presence in virtual environment have been studied in three main categories including non-immersive, immersive, and full-immersive.

Application of biomimetics has expanded progressively to other fields in recent years, including urban and architectural design, scaling up from materials to a larger scale. Besides its contribution to design and functionality through a long evolutionary process, the philosophy of biomimetics contributes to a sustainable society at the conceptual level. The aim of this review is to shed light on trends in the application of biomimetics to architectural and urban design, in order to identify potential issues and successes resulting from implementation. In the application of biomimetics to architectural design, parts of individual “organisms”, including their form and surface structure, are frequently mimicked, whereas in urban design, on a larger scale, biomimetics is applied to mimic whole ecosystems. The overall trends of the reviewed research indicate future research necessity in the field of on biomimetic application in architectural and urban design, including Biophilia and Material. As for the scale of the applications, the urban-scale research is limited and it is a promising research which can facilitate the social implementation of biomimetics. As for facilitating methods of applications, it is instrumental to utilize different types of knowledge, such as traditional knowledge, and providing scientific clarification of functions and systems based on reviews. Thus, interdisciplinary research is required additionally to reach such goals.

Redesigning and retrofitting cities so they become complex systems that create ecological and cultural–societal health through the provision of ecosystem services is of critical importance. Although a handful of methodologies and frameworks for considering how to design urban environments so that they provide ecosystem services have been proposed, their use is not widespread. A key barrier to their development has been identified as a lack of ecological knowledge about relationships between ecosystem services, which is then translated into the field of spatial design. In response, this paper examines recently published data concerning synergetic and conflicting relationships between ecosystem services from the field of ecology and then synthesises, translates, and illustrates this information for an architectural and urban design context. The intention of the diagrams created in this research is to enable designers and policy makers to make better decisions about how to effectively increase the provision of various ecosystem services in urban areas without causing unanticipated degradation in others. The results indicate that although targets of ecosystem services can be both spatially and metrically quantifiable while working across different scales, their effectiveness can be increased if relationships between them are considered during design phases of project development.

Architectural design is one of those areas that have actively employed interactive design tools such as CAD/CAM software. In order to add a realistic view of the design results in the 3D work process, there have been several recent attempts to employ a virtual reality technology that allows architects to explore design in 3D space. However, VR’s weakness is that common interaction tasks, such as navigation and selection, are still not supported conveniently in 3D space. In addition, VR devices are generally unfamiliar to the average person and are too expensive to use. This paper presents a VR framework that makes the design task easily achieved by employing a PDA interface for a VR interaction applied to street-view emotional color design problems.

The City

Tripoli is a city of a Mediterranean Sea climate; this has contributed with some social and religious factors to affect the architectural and urban design, which all originally has come from the Islamic content. This study argues the climatic features of Tripoli in order to show the ways followed by the Libyan Muslim architect. In other words, these ways were used to adapt with the climate and create the demanding architectural treatments, which have served the building units. This is considered as a study case that can discuss the possibility of the climatic reflection on the walls. That is to say, the walls’ thickness, the type of the used substance in building, the substance’s properties, the type of roof used in covering the building units and the architectural design of the building as treatments achieved professionally by the architect in decreasing the heat in summer and increasing the heat in winter through the mass block. Additionally, the researchers have stated that Tripoli’s building design respected the privacy of the inhabitants and their isolation from the world outside their buildings. That is because they wanted to have their own cold spaces inside which were rich of light, air and shadow. As a result of the aforementioned considerations, the architectural buildings contained the uncovered space and the broken entrance to keep the privacy from the passengers and to protect the inhabitants from wind and sand. These were regarded as final solutions for the architectural and climatic problem. Further, this study illustrates the active role of using the planning including the architectural formations and the treatments of motion path. That is according to their width, their length, their form, their guidance and their direction change in order to make shadow and isolate the front of buildings. This also contributed to give the streets the northern wind which in turn helped to keep the air moving as long as possible to tone down the climatic influences. Moreover, the planning aimed to show its turn through analytical, architectural and documentary survey for realistic examples in the archeological registrar of the potential city treatments. These architectural elements were important in making the sustainable architecture in respect to the environment and human relaxation requirements. Finally, the researchers measured the following factors temperatures, wind, rain, and ratio humidity for variety of spaces in the city. That was followed by qualitative and quantitative statistical analysis supported by graphs
