Hi. Working on a transportation hub project where the west facing multistory 50-60' glass facade is broken up vertically by an adjacent roadway bridge that runs the length of the building at the 40' mark. That structure causes a shaded condition beneath. We are exploring an etched glass for lighting and temperature control inside the building, but the initial thought is to only do so in the 40'-60' elevation range of glass where sun has its effect. The roadway bridge is wider than the building is tall. So it really looks more like the building rises from the roadway up 10-20' even though the building does go below the roadway bridge down to the lower roadway. How would the zone calculations be effected by this? Does the whole facade still apply? Or are we only worrying about the 10-20' above the road? Thanks in advance.
