My solution was to provide a physical barrier to protect the office from the sun. First we applied a sheet of adhesive material to the window that allows you to see out of from the inside, but blocks much of the light coming in. I also designed and printed some sections of this material to promote some of the world destinations that the travel agent offers packages to. I then designed a series of solid facia board constructed from a combination of wood, stainless steel and plastic that incorporated the company logo to be mounted outside the window as another physical barrier to the heat of the sun. These facia boards are all removable from the frame to which they are mounted to allow for cleaning of the windows behind them. The large white board actually has a hinged glass front in a stainless steel frame and can be opened up to allow posters to be displayed detailing the latest promotions on offer by the travel agent. Everything that was installed fits between the window and the existing security shutters so that it is protected when the office is closed at night.
We completed all work with this small project a little over a week ago and are happy to report that it has solved the problem.... the office is now cool and airy, and passers by never miss the office because not only are the security shutters open all day, but the company also has a greatly increased street presence as a result of the new signage.
Here is the office as it was, the CAD concept that was presented, and the final result.
