Sun shades

This building has large sheets of stainless steel shielding its huge windows from the bright sunlight. Fairly redundant in winter months, they're very useful in the summer months to help regulate the temperature inside the building, thereby reducing the energy consumed by the central air conditioning system.

There's one area in the middle of the building where (for asthetic reasons) there are no sun shades. Even though the windows are tinted, offices in this part of the building tends to be a few degrees warmer in the summer months. Every now and again, when my office become to chilly, I find a reason to visit colleagues in this area for a quick cup of coffee. :)
