This is a "personal memoir" that is exemplified with references for some 190 international publications in the field of the architectural and engineering design of buildings that span the author's career from the University of Glasgow, to the University of Strathclyde and then to the Glasgow School of Art where the author currently holds a part-time post.

The 41 papers selected for inclusion in this submission deal with: the issues of how data can inform extreme demand in engineering systems; the theory and methodology of the design of buildings; the simulation of thermal and light energy; computer visualization of the built environment; the evolution and future of virtual and augmented reality; the application of multi-media technologies to our cultural heritage; the modelling of cityscapes; user participation in building design; and the dissemination of all of these emerging computer-based applications to the practice and education of building design.

The thesis also identifies the acknowledged pivotal role of the author in a number of international organizations including eCAADe (Education of CAAD in Europe - founded by the author), the Design Research Society ( of which the author is the first Honorary Fellow, SIGRaDi (Sociedad Iberoamericana de Grafica Digital - from which the author has a lifetime award), IBPSA (International Building Performance Simulation Association - from which the author has a lifetime award) and the RIAS (the Royal Incorporation of Architects
in Scotland - of which the author is an Honorary Fellow) and ACADIA (Association for CAD in America); it also includes an Appendix - the 'Festschrift' issue of the International Journal of Architectural Computing devoted to the author's contribution to the evolving field of CAAD.
