Virtual Reality (VR) is an exciting new technology that offers considerable potential benefits for all stages of Architecture, Engineering and Construction processes, from initial planning and conceptual design to facility management and operations. Augmented Reality (AR) is a natural evolution of the VR technology; it allows the user to see the real world, with virtual objects superimposed upon or composited with the real world. Therefore AR supplements reality, rather than completely replacing it. VR and AR can be applied as a vehicle for the whole life cycle design and operation of AEC projects. Sustainable research efforts throughout the world are pushing the frontier of knowledge in terms of utilizing and implementing VR and AR.
