Analysis

Hypothesis 1

Hypothesis 2

Hypothesis 3

Hypothesis 1 - Morrill Hall allows for sufficient light (20 - 25 footcandles) into the workspaces to perform required tasks.

First Case: Floor 1, Zone A
	This case study is located on the first floor of Morrill Hall in the NorthWest corner of the building. This is the Office of Graduate Admissions and the primary work done here is clerical, with the use of computers and some paper documentation. Location Natural / Artificial Illuminance (fc) A 16.4 / 47 B 20 / 54 C 20.5 / 56 D 13.3 / 48.1 Meter reading conditions: Date: April 30th Time of Day: 2 - 3 PM Sky Conditions: Clear

The image and diagrams above show the conditions present in this office space on April 30th at 2:15 PM with clear skies. The space is mostly open with little obstructions that would affect light reaching workspaces. The only obstructions worth note would be a bookshelf located immediately adjacent to the south side of the desk labeled "C" in the diagram. The only conditions that might affect this test are the cleanliness of the windows. At the time there was a significant buildup of dust, dirt, and scum that would reduce the amount of daylight entering the space.

Second Case: Floor 2, Zone A
	This case study is located on the second floor of Morrill Hall in the south area of the building. This is the EPOC offices. The primarily work done here is clerical, with the use of computers and some paper documentation. Location Natural / Artificial Illuminance (fc) A 16.8 / 79 B 16.5 / 60 C 8.4 / 41 D 21 / 40 Meter reading conditions: Date: April 30th Time of Day: 2 - 3 PM Sky Conditions: Clear

The image and diagrams above show the conditions present in this office space on April 30th at 2:35 PM with clear skies. This room is bisected by a 4 ft high partition that is oriented parallel to the south wall for the majority of the room. Archive storage is against the north wall, so this partition doesn't affect the light levels much for the north half of the space. However, there is a desk located at point "C" in the diagram which had much of it's light blocked by these partitions.

Third Case: Floor 3, Zone A
		This case study is located on the fourth floor of Morrill Hall in the NorthWest corner of the building. This is the Graduate Student Offices. the primary use of this space is a gathering area and reading room. Clerical work using computers and other forms of paper documentation is also done here. Location Natural Illuminance (fc) A 80 B 1 C 1.4 D 1.7 E .8 F .02 G 1.1 Meter reading conditions: Date: April 30th Time of Day: 2 - 3 PM Sky Conditions: Clear
This image is looking at the "A" sample location in the diagram above. This is the only area of this room to receive significant daylighting.	This image is taken at location "F". There is almost no daylight reaching back to this area of the room, mostly due to light being blocked by partitions and bookshelves.

The image and diagrams above show the conditions present in this office space on April 30th at 3:05 PM with clear skies. This room was the least-satisfactory room regarding lighting conditions according to the surveys taken by the inhabitants. This room receives very little light because it has only one window, located at the very West end of the room. The walls surrounding this room ass connect to attic spaces, making this room essentially enclosed from all exterior walls. There is a conference table and book shelf / library located on the East side of the room. The many partitions located in these rooms blocked much of the light from getting more than a few feet into the space.

Hypothesis 2 - The floors of Morrill Hall that exceed a 10’ floor-to-ceiling height suffer from a heat stratification of at least 5 degrees Fahrenheit.

Hypothesis 3 - The single-pane windows are a source of heat transfer (heat gain or loss of 200%)

North The North side of the building's outside temperature was measured at 71.0 degrees. In the room on the left, the AC was off and the room temperature was 77.5 degrees while the windows were measured at 74 degrees to 75.5 degrees suggesting that the windows were being slightly cooled by the temperature outside and possibly affecting the temperature inside. It could also be said that the heat inside is being dissipated to the outside through the windows. The same can be said for the central entry where the inside temperature is at 76 degrees yet the temperature near the window is 73.5 degrees. The room on the right side had an AC unit running so the room temperature was measured to be the same as at the windows. The window temperatures for the windows in the room to the right are similar to the temperatures in the room on the left which does suggest that there is thermal transfer through the windows despite having the AC on or not. The window with the AC unit in it is significantly cooler than the other windows which shows that the AC unit is able to pass it's output temperature to the window as well. Average temperature difference from the outside temperature to the window temperature is 3.16 degrees. Average temperature difference from the inside temperature to the window temperature is 2 degrees.
South The South side of the building's outside temperature was measured at 73.0 degrees. In the room on the left, the room temperature was 77.5 degrees while the window was measured at 82.5 degrees and was getting hit by direct sunlight. The room next door had its AC unit on and the room temperature was 74.0 degrees while its window, which was partly shaded by a tree, was measured at 76.0 degrees. In the room to the right, the the room temperature was 75.0 degrees while the windows were measured at 74.5 degrees and were also shaded by trees. The South measurements suggest that if a window is not directly shaded then there is significant heat gain in the room, as is seen in the leftmost, and hottest, room. Average temperature difference from the outside temperature to the window temperature is 3.875 degrees. Average temperature difference from the inside temperature to the window temperature is 1.375 degrees.
East The East side of the building's outside temperature was measured at 67.0 degrees. This is likely due to the heavy vegetation and shade on this side of the building. The inside temperature differences to the window temperatures for this side of the building were very comparable. There was an average temperature difference of only 1.25 degrees form inside the room to the window temperature. There is a higher disparity from the window temperature to the outside temperature suggesting that the windows here on the East side of the building held in temperature much better than the ones on the North and South Average temperature difference from the outside temperature to the window temperature is 4.5 degrees. Average temperature difference from the inside temperature to the window temperature is 1.25 degrees.
West The West side of the building's outside temperature was measured at 72.0 degrees. I was only able to gather data from one window on this side of the building. The sunlight was not obscured from coming through the window on this side of the building and room. The interior room temperature was  77.5 degrees and the window temperature read at 78.5. These windows in this room were the only two that were significantly at a higher temperature than the inside temperature suggesting that the sunlight heat/radiation is easily caught by the windows and transferred into the room despite the outside temperature being 6.5 degrees cooler. Average temperature difference from the outside temperature to the window temperature is 6.5 degrees. Average temperature difference from the inside temperature to the window temperature is 1.0 degrees.
