The same greenhouse effect that will help keep the lobby warm in the winter will be a problem in the summer. I wonder if they can add exhaust vents or openable windows on the glass roof in order to create a cooling draft, with cooler outside air entering from the open vestibules on the main level and the warmer air escaping from the roof?

Just like a greenhouse, you would have open or operable vents at the roof to circulate air up and out through the top of the building. Similar principle of those double glazed facades with empty plenums to move air warmed by the sun out of the building. The alternative is highly reflective glass, but vast expanses of glass always make well conditioned spaces futile. That’s why the outdoor atrium makes sense
