The graphs from the HOBO data proved to be somewhat useful in testing the shading devices.  The intent was to record temperature differences between the top and bottom of the windows.  If the lower HOBO had a significantly higher temperature reading than the upper HOBO during the same time period, it would indicate that the sun was shining directly on the lower HOBO while the upper HOBO was being shaded.  Our graphs show that in general, the lower HOBO had a higher temperature reading than the upper HOBO. However, there are places on the graph where the opposite is true.  External factors, such as cloudy weather and interior temperatures changes caused by the mechanical heating and cooling systems, likely affected the temperature readings, causing them to be slightly inaccurate for our purposes.

Suntool Models:

These computer models showed that the roof adequately blocks the sun during the summer except in the early morning and late afternoon, when the sun shines directly into the east and west windows.  In the winter, this situation is desirable; allowing the sun to enter helps to heat the building during this season.  But, in the summer, sun penetration causes an excessive internal heat gain and the cooling system has to operate almost constantly.  Adequate shading still occurs during the middle part of the day.

Photographs:

The pictures show the same results as the Suntool Models.  Adequate shading occurs during the middle part of the day, but in the early morning and late afternoon, the sun is able to enter the building unimpeded.
