Introduction Hypothesis Analysis Methodology Data Conclusion

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. to be continued…

Hypothesis 1 1ATemperature at different locations around the Lewis Center varies more than 5 °F 1BThe 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 Put HOBO data loggers in 10 locations throughout Lewis Center at 10pm Use Testo Velocity Anemometer to check wind speed at those 10 locations at 9.30am and 11.00am Use Raytek Infrared Thermometer to measure MRT at those 10 locations at 9.30am and 11.00am Use Kestrel Pocket Weather Meter at those 10 locations at 9.30am and 11.00am noon collect HOBO data loggers.

Conclusion The results of our measurements show: The greatest difference in temperature between the rooms is 7° F at 11:00 am. The greatest difference in relative humidity is 7% at 11:00 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.
