For employers, office redesigns can pay off big - Apr. 10, 2007: "Consider this insight, which came from the General Services Administration decades ago: Of the total cost to a company for running an office building over a 30-year life span, the initial construction represents just 2 percent; operating expenses come to about 6 percent.

The remainder? It all goes to paying the workers inside. The point should be obvious: People are the biggest cost inside a work environment, so leveraging your human capital ought to be near the top of your priority list."

I'll have to remember this. I've known for a long time that bad design is bad for you and bad workplaces are not productive. Peopleware or Mythical Man-month talked about that. 

Actually this is close enough to the Pareto 80/20 split that I am not surprised and can believe it.
