This research explores how parametric modelling integrated with environmental simulation, in combination with virtual and augmented reality, can be deployed at the early stages of design. Our approach is based on an integral design strategy, which gives equal weight to quantitative and qualitative evaluation. In effect, the study investigates how the qualitative aspects of post-occupancy evaluation can be brought forward to the early ‘pre-BIM’ stages, where the most added value can be delivered at the least cost. This paper reports the implementation of two software prototypes. A VR (Virtual Reality) application uses quasi-realistic graphics and spatial soundscapes to provide a virtual experience, where users undertake tasks and provide voice feedback, in combination with activity tracking and surveys. The second prototype uses AR (Augmented Reality) technology to compare design options: interactive models appear on a conference table; these are overlaid with environmental performance data; user activity tracking; survey data; and protocol analysis of voice comments. For the purpose of providing proof-of-concept a simple architectural design context is being examined – the simulation of a typical commercial office environment. The paper discusses preliminary feedback on the prototype applications, in advance of the next stage of the research where full evaluation with end users will be undertaken.
