I used to work in a high rise office building that housed somewhere between 80-100 people per floor.
Now I work in a renovated old building. It has only one floor and has workable windows.
My office layout is one of the reasons that I still feel comfortable going to work every day.
Until this virus clears out, a lot of office buildings are basically germ factories.
Now AZ moves into heavy AC season which will be even worse.
Just ask the folks welding into their buildings in Wuhan.
