Week 3 Update - C527 and C505 Fixture Counting and Power Monitoring

Hello

Today I went to C527 and measured the lux reading at different points in the room and  calculated the total power consumed, the total number of fixtures and lamps in the room. I included pictures of the Light Meter and Electricity Meter I used.

To find out the lux readings in C527, I took a cart with a Light Meter and moved around the room taking lux readings at different points. Four points in the corners of the room and Three points in the front, middle, and back of the room. When taking my readings, I would take them three times letting the numbers stabilize  to make sure I took a proper reading at each point. Each of the readings are:

• Point 1 (Front Left Corner) = 430 Lux
• Point 2 (Front Right Corner) = 496 Lux
• Point 3 = (Back Left Corner) = 342 Lux
• Point 4 = (Back Right Corner) = 553 Lux
• Point 5 = (Front of Room) = 516 Lux
• Point 6 = (Middle of Room) = 594 Lux
• Point 7 = (Back of Room) = 567 Lux 
• Average = 499.71 Lux

To find the total power consumed in C527, I found the source of power at one bench which was a outlet next to the LabVolt station in which everything on the bench was connected to. I took out the plug and put it into a Electricity Meter and plugged them into the outlet. From there, I turned on all the computers, the everything on the LabVolt station, the Reliable Controls, and the EasyIO so that I would get an accurate reading which was 272 Watts for the first bench. Then, I took 272 Watts and multiplied it by 12 to find out the total power consumed by all the benches which was 3264 Watts.

I figured out the total number of fixtures in the ceiling by counting the number of fixtures in the first row and I found out there was 6 fixtures. To find out the total number of fixtures, I multiplied 6 by 7 which was how many rows of fixtures there was and the total number of fixtures was 42 Fixtures. 

I also found out the total number of fluorescent lamps in each lamps by multiping 2 (the number of lamps in each fixture) by 6 which was 12. Next, I multiplied 12 by 7 and found the total number of lamps was 84.  

I also went into C505 and took Light Meter readings at different points in the room and calculated the total number of light fixtures and lamps just as I did in C527. So here are the lux readings I took:

• Point 1 (Left Front Corner) = 494 Lux
• Point 2 (Front Right Corner) = 432 Lux
• Point 3 (Back Left Corner) = 316 Lux
• Point 4 (Back Right Corner) = 445 Lux

I figured out the total number of light fixtures in the ceiling of C527 by finding that there where 4 fixtures in the 1st row, but 6 in the others. Next, I multiplied 6 by 4 which was the number of rows that have 6 fixtures and got 24. Then,  I added 24 and 4 and get 28 as the total number of fixtures.

I calculated the total number of lamps by multiplying 2 by 4 to get the number of lamps in the 1st row. Just like C527, there are 2 lamps per fixture. After that, I multiplied 2 by 6 to get 12 and I multiplied 12 by 4 to get 48 which was the number of lamps in the other rows. Finally, I added 48 and 8 to get the total number of lamps which was 56.

Now, I was told to do what I did for C527 for C505 and I only did the lux readings and the fixture/lamp calculations, but not the total power measurement/calculation because I would have to knock out the power to a bench in order to put in the Electricity Meter and that would be annoying for my class mates. Not to mention I would also take up a lot of space doing this. I'll have to figure out how I can do this without disturbing my classmates.
