Analysis 2 - Temperature Stratification
In our analysis of the temperature stratification effect in the WRC, we found some unexpected information. The HOBO at the lowest elevation ended up having the highest temperature in the space. Moving higher in the space revealed that the HOBOs began to record lower temperature readings.
We have many theories as to why this data was recorded on the HOBOs in such a manner. Beginning with the top HOBO we believe that leakage of conditioned air from the office windows and a lack of direct sunlight affected the ambient temperature around the upper recording level.
The middle HOBO read the second highest readings. It was placed on a concrete wall, so there was a great deal of thermal mass, and the vertical location was such that direct sunlight was able to strike the HOBO.
The bottom HOBO was underneath the stairs. There was a 100 watt light bulb underneath the stairs at this location. The stairs are made of solid concrete. We believe that the heat of the light bulb can become trapped under the stairs along with heat from the sun during the day.
