I live in a converted warehouse apartment building in Richmond, VA. The apartments themselves are still partly under construction and have been since I moved in last October. We get a whole lot of dust coming into the apartment and I was curious if the return air on the HVAC is the cause. It looks like the system receives its air from inside the small attic structure over the bathroom and this is closed off. Only a vent above the access door allows the apartment air to enter. It is reasonable to me that these should probably be connected. Does this violate any building codes? Would this cause for inefficiencies in the HVAC system? I do not know anything about construction or building codes and I am uncertain how to proceed. My wife is pregnant with our first child and the purity of the air is less than ideal. I've attached some photos to hopefully illustrate this better.
