Research Completed Research Completed

• Every load was analyzed and accounted for
• All panelboards and switchboards resized
• All panelboards relocated (second floor only)
• Recircuited all of second floor lighting and power

to coordinate with new panel boards and get an idea of new branch circuit lengths, etc.

• Cost analysis of old equipment size and

installation vs. new equipment size and installation

New panelboard locations New = RED Old = BLUE

Also took into account all feeder runs and circuit breaker costs associated with old and new system

Electrical summary

• Savings not extrao

Savings not extraordinar rdinarily high ily high

• reasons for this would be the extra transformers

nullified a lot of the money saved by the smaller equipment

• had this building been larger, cost savings would

have continued to go up very quickly, because no more transformers are needed (larger sizes maybe)

• Still save money

Still save money regardless regardless

• Added flexibility
• Added flexibility

Mechancal Breadth

My Mechanical Breadth work focused on the PA Career Space and the addition of skylights. My initial concern was the added skylights would increase the cooling load to a point that the mechanical equipment would need to be resized. I used HAP (Hourly Analysis Software), and implemented the proper variables to obtain the additional load created by the skylights.

Skylight load

This number represents the Sensible load from both the skylight transmission and skylight solar loads

45.61 btuh/ft²

1 ton = 12,000 btu 45.61 btuh/ft² x 64 ft² = 2919.04 btuh 2919.04 btuh x 1 ton / 12,000 btu = 0.24 to 0.24 tons ns

Lamp Heat Dissipation

The number of lamps is actually decreased in the new lighting layout.

1.66 tons 1.66 tons = previous lamp energy output 0.67 tons 0.67 tons = new lamp energy output 1.66 – 0.67 ~ 0.99 Tons

0.99 Tons

0.99 Tons - 0.99 Tons - 0.24 = .24 = 0.75 Tons

0.75 Tons (less cooling)

Mechanical conclusion Mechanical conclusion

In conclusion there is no need to resize the mechanical equipment. As I found out, there is actually less cooling needed even with the

• skylights. This is due to the drastic decrease in

number of lamps being used in the PA Career space.

Summary Acknowledgements Questions

Structural Breadth Structural Breadth

For my structural breadth work, I redesigned the structural layout and sizes of the joists surrounding the skylights in the PA Career Space.

Structural Analysis Structural Analysis

After taking into account all the variables and calculating Dead Load and Live Load, I was able to size the joist according to the proper spans and lengths. These loads are not taking into account the skylights, so we are over sizing slightly. Dead Load = 432.9 432.9 plf plf Live Load = 312 312 plf plf

Structural Study Conclusion

In conclusion, it appears the skylights will not be a very large problem in terms of resizing or cost. While new joist sizes are larger surrounding the skylights only, the proposal also omits four joists from the

• riginal plan. This should offset any

significant cost associated with this change.
