I imagine that every major neighborhood has an attraction or two that is a draw for locals and visitors alike. Such as museums, theme parks or shopping malls. One of our city’s major attractions is a museum that is dedicated to space flight and its development, however it’s a place I have loved to visit ever since I was a kid, and each year it seems to grow a little greater and more interesting. They have all different types of artifacts from the early days of the space program all the way through modern times. There is a tiny admission to get in, but I think that this largely goes to spend money for the electricity for the air conditioner. The building is basically a massive hangar, and the ceilings are pretty high to accommodate some of the rocket displays. In order to preserve these artifacts to the fullest, the must be kept cool. Therefore the giant Heating and AC systems supply the cool air that flows through the exhibits. There are huge metal ducts that hang from the ceiling that route back to the main air handler unit to make sure the temperature in the building stays at a nice cool temperature all year long no matter what. The Heating and A/C unit also helps take the humidity out of the air, which is really crucial in preserving the artifacts on the museum, however needless to say, the space museum is a popular place to go when it the heat of Summer is in full swing, then for a small fee you can spend all day wandering around in a nice air conditioned building and not have to worry about getting too hot and humid.
