Critical to the increasing population with dementia, is a need to change the social perceptions of mental health facilities as linked to the design of asylums and prison architecture. The availability of facilities that educate, rehabilitate and provides therapeutic and healing environments is a need for both patients and their carers. Literature suggests that well designed environments for a small group of patients in a home like environment influences dementia patients’ behavioural attitude and aid in retention of physical abilities to move within the spaces and reduces agitation levels. (Lawton,2001,and Nagari, 2016). This is a preliminary review of research published between 20102017 linking the impact of building design decisions to environmental effects on dementia patient behaviours in car...

Unexpectedly, communities use convenience stores as thermal comfort refuges during summer. This study utilised a dataset of 251 convenience stores in Taiwan from the largest leading retailer to obtain data on the physical, construction elements, energy use and siting of convenience stores. Sample analysis results analysed the architectural features and main locations, urban setting of the convenience store for a base case design. The dynamic software IES-VE (2016) is used to simulate different envelope improvement techniques to understand cooling demand and indoor thermal performance in relation to an urban setting. The dataset energy loads were used to validate the simulation results. The simulation results show that the most efficient building envelope improvement type is an insulation roof with shading. It saves 17% of cooling load in arterial roads while saving up to 18% of cooling load in residential areas.

Its positive climatic effectiveness as a traditional solution are herewith questioned. In order to improve the microclimate conditions at pedestrian level three different shading scenarios addressing the form and the opening of shading devices were simulated using CFD Fluent, based on two dependant variables including air temperature distribution and wind velocity. The findings show that typology and the opening locations are the paramount factors in providing a temperature reduction in the urban scale.

This paper attempts to find changes in public perceptions over the last three decades and differences between experts and the public over different land-use options. A semi-structured questionnaire that integrates a visual survey of 10 images of WT technology in different urban, landscape and seascape settings was presented to both groups. The perceptions of siting, proximity, landscape type, and maturity of urban wind turbines’ technology in renewable energy generation were contrasted. The results revealed that both the public and experts alike significantly preferred images of WT inclusion in seascape and landscape settings and responded negatively to images of WT as an addition to buildings in urban contexts. Images of wind turbines around transport settings were ranked in the second set of acceptances, afte...

One of the technologies that have high potentials for integration within the built environment is roof mounted wind turbines. However, there is a state of uncertainty regarding the feasibility of these wind turbines. This paper argues that this uncertainty is attributed to uninformed decisions about the locations of installing urban wind turbines without considering the accelerating effect of different roof shapes, buildings' heights and surrounding urban configurations. This paper aims to present the results of Computational Fluid Dynamics (CFD) simulations for the purpose of identifying the effect of different roof shapes on the energy yie...

Yet, it can lead to a reduction in the daylight availability leading to visual discomfort. According to the Illuminating Engineering Society of North America (IESNA, 2000, 2011), it is essential that daylight effects be considered in any space where daylight is admitted, even if it is not exploited as a light source, in order to reduce the need for artificial lighting. Therefore, an analysis of solar access and shading is necessary for to assure visual comfort underneath the shading tents. This paper attempts to investigate seven different shading scenarios addressing the solar radiation access underneath, in compliance with ANSI/ASHRAE/IESNA Standard 90.1-2007 recommendations, by employing DIVA, which is an integration of Radiance and DAYSIM with thermal load simulation using Energy Plus within [1].

The paper addresses the problem of designing efficient shading devices for buildings. The novelty of this project is a dynamic design for shading devices, new in the market of photovoltaic and concentrator systems, that changing orientation and configuration, allows the best lighting comfort in buildings while producing energy. This device consists of a series of linear low concentrator with monoaxial sun tracking and a semi-parabolic profile reflector providing the solar radiation concentration into a string of mono-crystalline cells PV, with 5,5x concentration factor. The thermal energy production is achieved through the cooling system of the device whereby hot water is produced. The contribution of this study is a new concept and developments in solar thermal concentrator systems revealing new trend for the technology to be integrated into architecture, especially in dynamic solution for shading devices.

This paper reflects on current developments in VR technologies and describes an approach adopted for its phased integration into the academic curriculum of built environment students. The process and end results of implementing the integration are discussed and the paper illustrates the challenges of introducing VR, including the acceptance of the technology by academic staff and students, interest from industry, and issues pertaining to model development. It sets out to show that fairly sophisticated VR models can now be created by non-VR specialists using commercially available software and advocates that the implementation of VR will increase alongside industry's adoption of these tools and the emergence of a new generation of students with VR skills. The study shows that current VR techno...
