Possibly for fire rating. Wire mesh glass was common on fire rated doors to stairways and such, although there's other ways to accomplish that now.
Edit: I had some trouble with the site, but figured it out enough to see that the offices have big doors, and then a window next to them that's mesh glass. Some of the doors have fire door tags (although you can't read them, and I only found one), and most don't. I suspect there was a code requirement for some of the offices to have fire rated construction, thus the fire door, and then you need the window and the drywall also fire rated. Other offices probably didn't need that, but maybe they used the same glass for everything for consistency.
But, I'm not an architect or an appropriate engineer, my spouse holds a bachelor's degree in architecture, so I've got some knowledge by osmosis.
Thanks. It seems such glazing was common in American 1970's era construction as a way to evenly distribute across the pane and into the frame the heat from a fire on one side of the window. This extends the time before the glass shatters, which once shattered allows flames/smoke through. It has commonly been misunderstood to be "stronger" glass, an overloaded term that might have some applicability to fire resistance, but has given people the wrong idea about impact resistance. Glazing with embedded wires is much less impact resistant whilst also posing additional safety risk to humans impacting the glass. When humans attempt to pull themselves out of glass they've impacted, the wires hold sharp glass shards in place causing even more severe injuries.[1]
It looks like all adjoining offices on the exterior of the building are single fire zones, with stairwells at either end of each zone. Internal offices seem to be divided into fire zones too (e.g. 6x2 rooms as a single zone) with use of the odd internal slab-to-slab wall that would possibly be fire resistant.
