The impact of computer aided architectural design programs on conceptual design in an educational context.

Little research has been undertaken concerning the manner in which students use computer aided architectural design (CAAD) programs for conceptual design. The research aim was to explore the potential impact of CAAD programs as conceptual design tools within architectural design methodologies. Therefore, the study aimed to understand the effect of CAAD on self-reflection using a think-aloud method. The findings demonstrate that participants used CAAD representations for concept development, information visualisation and presentation of design strategies. Results from the detailed analysis of design process are enlightening, particularly in terms of the cyclical nature of conceptual design. Furthermore, the use of a micro-detail protocol study within this context suggests an appropriate methodology for application in further study of the architectural design process

The application of visual environmental economics in the study of public preference and urban greenspace.

Urban greenspace has consistently been argued to be of great importance to the wellbeing, health, and daily lives of residents and users. This paper reports results from a study which combined the visualisation of public greenspace with environmental economics, and which aimed to develop a method by which realistic computer models of sites could be used within preference studies. As part of a methodology which employed contingent rating to establish the values placed on specific greenspace sites, three-dimensional computer models were used to produce visualisations of particular environmental conditions. Of particular importance to the study was the influence of variables including lighting, season, time of day and weather on the perception of respondents. This study followed previous work that established a suitable approach to the modelling and testing of entirely moveable physical variables within the built environment. As such, the study has firmly established that computer-generated visualisations are appropriate for use within environmental economic surveys, and that there is potential for a holistic range of attributes to be included in such studies

The Influences of Actual and Perceived Familiarity on Environmental Preferences for the Design of a Proposed Urban Square

People gain actual familiarity through direct experience of environments, but environments we have never visited can still seem familiar. To date, few academic studies have investigated this phenomenon of perceived familiarity. This paper discusses the concept of perceived familiarity and environmental preference from the perspective of people who may be asked to make judgements of future urban designs as part of the planning process. A sample of local (n=102) and nonlocal (n=176) people were asked to rate images of two versions (existing environment and proposed redesign) of an urban square on scales of preference and perceived familiarity. Results showed that the mean ratings for the proposed design were similar for both local and non-local samples. However, we found a clearly discernible difference in the way psychological antecedents are associated with environmental preference. For nonlocals, preference for the existing design is significantly associated with preference for the proposed design, but for local people this is not the case. In addition, for non-locals perceived familiarity of the proposed design is associated with perceived familiarity of the existing environment, but for the local sample this is not the case. Implications for public participation processes in urban design, as well as limitations and future lines of research, are discussed
