The west end of the LCM office on the lower level has a cold spot near its floor.
Hot Spot: 72.9
Heater: 63.1
Desk: 65.4
Cold Spot: 62.9
Shelf: 64.5 Based on the above data, our hypothesis is correct: The west end of the LCM office on the lower level has a cold spot near its floor. There is a cold spot in the LCM office near the floor at its west end. The cold spot exists because the office is close to the back door of the building that goes outside. Every time the back door is open, a draft comes in and ends up in the LCM office at its west end where the door to the office is located. This problem is compounded two large single-paned windows in the office as well as uninsulated walls. Finally, by the time the water from the boiler reaches the pipes in the LCM office, the water is at its coolest point. This provides little warmth for the LCM office.
Water temperature is greatly reduced while flowing through uninsulated pipes from the boiler to the radiators.
By Removing the data from Pipes 2 and 3, it becomes visually clear that there is a definite difference in temperature between the beginning and end of the run of pipe.
Pipe 1: 90.2
Pipe 2: 83.2 (excluded from graph above)
Pipe 3: 81.8 (excluded from graph above)
Pipe 4: 74.1 The average temperatures that have been calculated from the Hobo data numerically confirm that the pipes do loose an average of about 16 degrees Fahrenheit from beginning to end. Therefore, our hypothesis is confirmed: water temperature is greatly reduced while flowing through uninsulated pipes from the boiler to the radiators. The fact that the pipes are uninsulated is a major factor in their heat loss from the boiler to the end of the pipeline.
The windows in the meeting space on the upper level provide adequate daylighting of 10-20 footcandles between 10:00 AM and 2:00 PM from march through september.
