This is why paperweights exist. Office buildings all used to have ventilator shafts which effectively created lower pressure in the interior of the building. In order to make it work, you needed to have your office window open AND an interior window open (typically above your office door, so you could still keep your door closed).

As you can imagine, there was a lot of wind whipping through offices. This is why the paperweight was invented -- and also why no one uses paperweights anymore.
