TURBULENCE IN THE LIBRARY
2
ABSTRACT There is a small library in the south
west corner of the second floor in the AJLC
center. The 400 sq. ft. room features a large
south facing window as well as clerestory windows
on the West and North sides. This space stores
resource materials in stacks on the East and West
sides. It also contains two computers on the
North end as well as one in the middle of the
room. In response to a few occupants complaints
we decided to investigate this space.

QUESTIONS 1. Why are the occupants uncomfortable
using the library? 2. How does the
air-conditioning operate? 3. What are the
air-flow patterns in the room with or without the
HVAC operating system? 4. What do the sensors
control? 5. How effective are the sensors? 6. Are
the transom windows operable? 7. Are the transom
windows effective? 8. Do the west facing windows
contribute to the glare conditions and heat
gain? 9. Is artificial lighting necessary during
day-time?

HYPOTHESIS
There is a 10 degree temperature difference
within the library due to heat stratification
between the floor and the ceiling.
