1. OBJECTIVE
Create lighting layout for complete office building
2. MATERIALS REQUIRED
Computer with requirements as shown:
o

3. INSTRUCTIONS 1.
Go to eCentennial and download the IES file for all luminaires listed in the Lab 4 folder to your computer.
9414DxxxLA44.ies
C6RN+C6L25835MZ10U+C6RCWCL.ies

2.
Go back to the Start menu and select Import plan or IFC
. Then import the file: Office Floor1.dwg
3.
To configure the plan draw origin and X-axis. If it is in the correct position you can skip this step and pick Next
. Specify scale by choosing the base unit in your CAD drawing. In our case pick Inch
and proceed

4.
Next step is to trace the building perimeter. Click on Site
icon then click on Draw new building. 5.
Left click on all corners of the building to trace the floor plan. After the last corner is clicked, right click to Close polygon.

6.
Click on Draw new interior contour, then select all corners of the first room in the same way as you did the entire building. Right click and select Close polygon to finish room. Repeat this step for all rooms in the building.

8.
Next we will add in all of the windows and doors. Click on Aperture icon then select Window as the active aperture.
Click on Draw new building opening
then click two corners of the window (along the long edge) to create the window opening. Repeat this step for all windows in the building.

10. To make an opening between Room 2 and Room 8 select Cutout
icon and click on points of the wall to cut. Hint: It may be easier to pick your points by rotating image and look from beneath the floor.

11. We are now going to create a general lighting layout for rooms 8 and 2. First import the luminaire file: 9414DxxxLA44.ies

Then select Draw rectangular arrangement and pick corners of the room to place luminaires.
12. Change target illuminance level to 60 fc. This should update the grid arrangement of luminaires to compensate.

13. For Room 2, choose Draw polygonal arrangement
and pick all corners of room to place luminaires. Change target illumination level to 60 fc.
14. For bathrooms in Room 7 and 10, import the luminaire file: C6RN+C6L25835MZ10U+C6RCWCL.ies
and create a new luminaire arrangements for those rooms. Change target illumination level to 35 fc.

15. For Rooms 4 and 5, import the luminaire file:
12x1lbcqe.ies
. Place a single luminaire in the center of the room by choosing Place individual luminaire
option. Rotate 90° and center in room. Change mounting height to 7.5 ft.
16.
For Room 1, create a 2x2 luminaire arrangement as shown below. Set mounting height to 7.5 feet.

1.
Based off your lighting report, which room has the highest average illumination level, and which has the lowest? The highest average illumination level would be in room 7, the lowest would be in room 6.
2.
Does the lighting simulation in Lab 4 provide a reasonably accurate simulation of lighting levels for that space? Why/why not? What could you add/change to your simulation to achieve more realistic lighting levels?
To make it more accurate, we could get precise measurements of the room. It
does not fully provide an accurate simulation of lighting levels because we could have misplaced the tables or stations in the room, which causes it to have a different calculation.
3.
Is it possible to achieve similar illumination levels using fewer luminaires? How would reducing the number of luminaires affect lighting uniformity?
Assuming uniform bulb spacing and increased lumens per bulb, comparable lighting levels could be achieved with fewer luminaires. There would be some areas that would be darker, which would impact on the uniformity of the lighting.
4.
What are the advantages of using lighting simulation software as opposed to calculating illumination levels by hand in this lab?
One benefit would be the elimination of human error in measuring and determining illumination levels as opposed to doing so by hand.
5.
How to the distribution patterns compare between the panel luminaires in Room 2 (general office space) and the downlights in Room 7 (bathroom). Refer to the spec sheets provided in the Lab 4 folder for polar intensity diagrams.
The C6RN+C6L2583MZ10U+C6RCWCL luminaires are used in the bathroom
of room 7, while the 9414DxxxLA44 luminaires are used in the general office space of room 2. Our comparative points are lumen production and shape. Room 2 features long, rectangular luminaires as opposed to room 7, which has circular luminaires. The lights in room 2 emit 35 fc less than those in room 7.
