Aluminum Feeders

Ann and Richard Barshinger Life Sciences & Philosophy Building Franklin & Marshall College Lancaster, PA

Pros: Cons:

  • Much less expensive
  • Lighter
  • Labor can be easier and
  • Larger wire size
  • More prone to oxidation
  • Use in residential and

potentially less time consuming branch circuits banned (can expand and loosen terminations, can result in fire) fire) Proper Installation:

  • Only use for feeders

y

  • Must be cleaned and have

antioxidant joint compound applied

  • Properly torqued at terminations

Acoustics Breadth

Ann and Richard Barshinger Life Sciences & Philosophy Building Franklin & Marshall College Lancaster, PA

Material Selected: Perforated Metal with Insulation

  • Adds interest
  • Solid and somewhat specular

material allows sound to fl t t b k f reflect to back of room

  • No gaps in layout – space is

unique but not overly modern

  • White finish best fit for
  • White finish – best fit for

color scheme of space and allows more light to inter- reflect

criteria even without ceiling IIC Target – 50

  • Current structure does not

meet criteria S l i R l VCT

  • Solution: Replace VCT

flooring for lab above with cork flooring

Conclusions

Ann and Richard Barshinger Life Sciences & Philosophy Building Franklin & Marshall College Lancaster, PA

Lighting Depth

  • Created a pleasing exterior environment with

more dark-sky friendly luminaires

  • Used energy-efficient luminaires in simple layouts

to allow features of spaces to stand out Electrical Depth

  • Central transformer is impractical in environment

with long, large feeders

  • Aluminum feeders allow for substantial cost
  • Aluminum feeders allow for substantial cost

savings Acoustics Breadth

  • New ceiling reflects sound well
  • Reverberation time is reasonable for a lecture hall
  • Sound Insulation is appropriate with change to

cork flooring for lab above lecture hall cork flooring for lab above lecture hall
