I think it's LEED and solar gain.
The quality of the glass would play a role, but Concord Brentwood, for example, has the wrap-around balconies to provide sun shading.
Likewise at Amazing Brentwood.
Cherish the older buildings with floor-to-ceiling and wall-to-wall windows.
The only recent condo tower I can think of that has expansive glass without balcony shading is the former Trump Tower, and it may have been approved so far beforehand that it didn't have to comply with the new(er) LEED requirements - or they went with more expensive darker tinted glass.
I think that the LEED goal is to reduce vision glass in condo towers to less than 50% of the surface
- which is brutal for BC's dark winters.
This is for passive design, but you get the idea...
