Introduction
After a walk through the building, our team
noticed variations in thermal conditions. The
vestibule was warm. The air in the corridor was
stale. At the second floor the office seemed to
be less humid. This lead us to wonder whether
these conditions were within the comfort zone or
we were just used to conventional buildings that
are designed to have very little variation in
thermal conditions, regardless of the function
the space.

Hypothesis 1
1A Temperature at different locations around the
Lewis Center varies more than 5 F 1B The
relative humidity at different locations around
the Lewis Center varies more than 10 .
Hypothesis 2
The thermal conditions throughout the Lewis
center fall outside of the thermal comfort zone
defined by ASHRAE.

Methodology
1. Put HOBO data loggers in 10 locations
throughout Lewis Center at 10pm.
D A Y 2
2. Use Testo Velocity Anemometer to check wind
speed at those 10 locations at 9.30am and 11.00am.
3. Use Raytek Infrared Thermometer to measure MRT
at those 10 locations at 9.30am and 11.00am.
4. Use Kestrel Pocket Weather Meter at those 10
locations at 9.30am and 11.00am.
5. 12 noon collect HOBO data loggers.

Conclusion

•  
• The results of our measurements show
•  
• The greatest difference in temperature between
  the rooms is 7 F at 1100 am. The greatest
  difference in relative humidity is 7 at 1100
  am. These differences were between the vestibule
  and the upper floor office. There was very little
  natural airflow within the building.
•  
• The thermal conditions are at the limit of the
  comfort zone, except for one space the
  vestibule. The upstairs area of the atrium was
  on the very edge of the comfort zone.
