title	Computer Imagery and Visualization in Civil Engineering Education
source	Journal of Computing in Civil Engineering, Vol. 14, No. 2, April 2000, pp. 134-140
summary	Higher education institutions in the United Kingdom have invested significantly in the implementation of communication and information technology in teaching, learning, and assessment of civil and building engineering—with mixed results. This paper focuses on the use of digital imagery and visualization materials to improve student understanding. It describes ways in which these materials are being used in the civil and building engineering curriculum, and, in particular, how distributed performance support systems (DPSS) can be applied to make more effective use of digital imagery and visualization material. This paper centers on the extent to which DPSS can be used in a civil and building vocational and continuing professional development context by tutors in the form of an electronic course delivery tool and by students in the form of an open-access student information system. This paper then describes how a DPSS approach to education is being adopted at Loughborough University as part of the CAL-Visual project. After highlighting the main aims and objectives of the project and describing the system, this paper discusses some of the issues encountered during the design and implementation of a DPSS and presents some preliminary results from initial trials.

title	Virtual reality as a visualisation tool: Benefits and constraints
source	CIDAC, Volume 2 Issue 4 November 2000 pp. 216-224
summary	The benefits and applications of virtual reality (VR) in the construction industry have been investigated for almost a decade. However, the practical implementation of VR in the construction industry has yet to reach maturity owing to technical constraints. The need for effective information management presents challenges: both transfer of building data to, and organisation of building information within, the virtual environment require consideration. This paper reviews the applications and benefits of VR in the built environment field and reports on a collaboration between Loughborough University and South Bank University to overcome constraints on the use of the overall VR model for whole lifecycle visualisation. The work at each research centre is concerned with an aspect of information management within VR applications for the built environment, and both data transfer and internal data organisation have been investigated. In this paper, similarities and differences between computer-aided design (CAD) and VR packages are first discussed. Three different approaches to the creation of VR models during the design stage are identified and described, with a view to providing sharing understanding across the interdiscipliary groups involved. The suitable organisation of building information within the virtual environment is then further investigated. This work focused on the visualisation of the degradation of a building, through its lifespan, with the view to provide a visual aid for developing an effective and economic project maintenance programme. Finally consideration is given to the potential of emerging standards to facilitate an integrated use of VR. The convergence towards similar data structures in VR and other construction packages may enable visualisation to be better utilised in the overall lifecycle model.

title	Optimising the design of building envelopes for thermal performance
source	Automation in Construction 10 (1) (2000) pp. 101-112
summary	Computer models for the simulation of the thermal performance of buildings have been in existence for many decades. Although these programs save a great deal of time and effort in computational terms they still rely on designers intuition and experience to achieve optimum solutions for a design problem. This paper presents a computer model which, not only simulates the thermal performance of the building taking into account design variables related to the building's envelope and fabric, but also applies numerical optimization techniques to automatically determine the optimum design variables, which achieve the best thermal comfort conditions. The main optimization program is supported by a graphical model for the design of window shading devices, which uses the numerical coefficients that define the window shading to model shading devices taking into account seasonal variations in solar angles and solar gains. The rationale and methodology used to develop the models is outlined and the resulting programs are described with examples of outputs. Finally, it is concluded that the models offer a valuable decision support system for designers at an early design state for the optimization of the passive thermal performance achieving optimum thermal comfort and savings in heating and cooling energy.

title	From CAD to virtual reality: modelling approaches, data exchange and interactive 3D building design tools
source	Automation in Construction 10 (1) (2000) pp. 43-55
summary	Virtual reality has the potential to improve visualisation of building design and construction, but its implementation in the industry has yet to reach maturity. Present day translation of building data to virtual reality is often unidirectional and unsatisfactory. Three different approaches to the creation of models are identified and described in this paper. Consideration is given to the potential of both advances in computer-aided design and the emerging standards for data exchange to facilitate an integrated use of virtual reality. Commonalities and differences between computer-aided design and virtual reality packages are reviewed, and trials of current system, are described. The trials have been conducted to explore the technical issues related to the integrated use of CAD and virtual environments within the house building sector of the construction industry and to investigate the practical use of the new technology.
