A peak in our numerical data for each location clearly shows a greater airspeed in the stairway vestibule. This confirms our hypothesis of an air velocity greater than 40fpm.  The average tested air speed in the vestibule is approximately 200fpm, with our lowest number in the data set never falling below 90fpm. Our highest readings exceed 700fpm, making the movement anything but consistent but always greater than 40fpm. At this point, we know there is a significant amount of air movement in the stair that is directly affecting the comfort level.

While testing our hypothesis we have made general assumptions and questions that we tested along the way. An initial idea was to find a link between the air speed and the temperature throughout the library. Measurements and comparisons show a very consistent temperature reading throughout the different locations, even in the vestibule, while the airspeed readings suddenly peak. A linear regression line confirms the comparison and proves the lack of a linear correlation between temperature and air speed.
