  35. Ann and Richard Barshinger Life Sciences & Philosophy Building Franklin & Marshall College Lancaster, PA Aluminum Feeders Pros: • Much less expensive • Lighter • Labor can be easier and potentially less time consuming Cons: • Larger wire size • More prone to oxidation • Use in residential and branch circuits banned (can expand and loosen terminations, can result in fire) Proper Installation: • Only use for feeders • Must be cleaned and have antioxidant joint compound applied • Properly torqued at terminations Jason Weaver Lighting/Electrical Option

  36. Ann and Richard Barshinger Life Sciences & Philosophy Building Franklin & Marshall College Lancaster, PA Aluminum Feeders Aluminum feeders are a practical option for this building Jason Weaver Lighting/Electrical Option

  37. Ann and Richard Barshinger Life Sciences & Philosophy Building Franklin & Marshall College Lancaster, PA Acoustics Breadth Sound Reflection: Jason Weaver Lighting/Electrical Option

  38. Ann and Richard Barshinger Life Sciences & Philosophy Building Franklin & Marshall College Lancaster, PA Acoustics Breadth Reverberation Time: Target – 0.7 to 1.1 seconds Ideal 0.5 seconds Acceptable Jason Weaver Lighting/Electrical Option

  39. Ann and Richard Barshinger Life Sciences & Philosophy Building Franklin & Marshall College Lancaster, PA Acoustics Breadth Material Selected: Perforated Metal with Insulation • Adds interest • Solid and somewhat specular material allows sound to reflect to back of room • No gaps in layout – space is unique but not overly modern • White finish – best fit for color scheme of space and allows more light to inter-reflect Jason Weaver Lighting/Electrical Option

  40. Ann and Richard Barshinger Life Sciences & Philosophy Building Franklin & Marshall College Lancaster, PA Acoustics Breadth Airborne and Structure-borne Sound Insulation: STC Target – 50 • Current structure meets criteria even without ceiling • IIC Target – 50 • Current structure does not meet criteria • Solution: Replace VCT flooring for lab above with cork flooring • New IIC is approx. 73 Jason Weaver Lighting/Electrical Option

  41. Ann and Richard Barshinger Life Sciences & Philosophy Building Franklin & Marshall College Lancaster, PA Conclusions 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 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 Jason Weaver Lighting/Electrical Option
