Using virtual and augmented reality to study architectural lighting

This paper presents industry stakeholder insights from the implementation of a dual modality
intervention using virtual and augmented reality simulation to study complex lighting theory in
architecture design. Using a design based research method the aim is to evaluate these insights and
inform a pilot study to educate first year architectural design students on the complexities of lighting the
built environment and methods to improve architectural workflow. The aim is to enable learners to
experience natural and artificial lighting methods comparatively in real-time through multiple
comparative visualisation methods. This is important to make informed evaluations regarding
architectural designs in terms of spatial quality, character, performance, and user-comfort levels. This in
turn allows architects to rapidly modify their designs to accommodate or mitigate the environmental
effects. Outcomes from the initial usability test highlight the ability to switch back and forth between the
virtual and augmented reality simulation technology, and between lighting visualisation modes as a huge
step forward by the industry stakeholders. Additionally, the idea of representing the physical building
where the simulation took place virtually using a detailed mapping gave a real-world anchor that made
the simulations easy to navigate, leading to improved satisfaction and engagement. However, the study
also highlighted improvements in the delivery of the simulation is required to improve simulation
learnability and efficiency.
