In this Vital Signs
case study we are trying to prove that two sets of double-sliding doors,
which creates a vestibule space, allows less heat loss than a single double-sliding
door entrance.
We went to the most
used entrance and placed four hobos to record temperatures for an hour
and a half while taking wind velocity readings. We used the temperature
readings to find the difference between the spaces which would show whether
or not a vestibule space is effective in preventing heat loss. The
assumption behind a vestibule entryway is that two small temperature changes
result in less heat loss than one large temperature change. We wanted to
see if this assumption applied to every entrance.
We found that this
assumption was not the case for the Eugene Airport entrance. Our
wind velocity readings did show, however, that the vestibule space did
prevent against significant wind flow into the building through the entrance.
