Very cool. Why do I keep thinking of a Stealth game sneaking around (with the lights turned low) or a FPS game where everyone’s shooting at everything and chairs, tables, computer screen, glass, etc. is all exploding and flying everywhere. Where this top-secret Biolab is where the evil villain (no offense if it is your client) is working on evil experiments and your role as a special shadow government operative is to infiltrate, download the data and escape with it. 
On a more serious note:
Indeed, if only research labs were this cool with dogs and zen gardens. And as you mentioned the lab equipment is well represented but actual labs would have tons more equipment and would not be so neat.
Some feedback:
-
The demonstration video should be done with a console-type controller. Movements were a bit jerky for people unfamiliar with navigating in such a manner.
-
Professional graphic designers (especially hardcore typographers) would prefer a different/better type and layout for the information popup cards.
-
The bits are of course superb, as a poster mentioned integrating the static and moveable objects so seamlessly is brilliant.
-
Are any of the lighting elements ? As a layperson to me that would be a nice gimmicky thing. Would it be possible also to replace the level seamlessly with an evening-lit scene for example (without having to do realtime GI per se).
-
As someone learning UE4, how do you foresee VXGI in your future projects/ workflow/ etc? What about app streaming to mobile/tablet?
-
Finally, I think one of the underexplored areas of realtime ArchiViz right now is health & safety, hazard management and emergency planning. For example, simulation of fires, sprinklers, emergency lighting, etc. While ArchiViz focuses on the beauty and interactivity of such environments would clients also as part of the building and approval want to understand and visualise how to handle such scenarios?
