> Having worked in an all-glass tower and also a "normal" office building, my personal experience is that the natural light that giant windows let in and the external views that they afford are both phenomenal improvements to the atmosphere. It's really a much more pleasant environment to work in. The only catch is that the interior or window treatment design needs to consider glare from sunlight directly hitting computer screens and/or eyes.

having worked in both well designed and poorly designed glass towers, I can say this: I personally appreciate a well-designed not-glass-waterfall. Being in Seattle, a lot of new towers have gone up that are just sheet glass panels. I've worked in various towers in Seattle and I've come to prefer some of the older style ones. The oldest of them do have issues with light, I'll fully agree with that. There is a difference between that and the absolutely insane floor to ceiling glass panels that make up some of these offices.

Glass towers just... They make monkey brain go scream on the inside and they're just aesthetically displeasing on the outside. They all look alike at one level and become hard to distinguish from one another. I hate walking through Downtown Seattle trying to remember which of the badjillion glass monoliths is the one I want -- unless I'm looking for one of the more unique buildings that is steepled brick and granite.
