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 feedersy• Must be cleaned and have
antioxidant joint compound applied
• Properly torqued at terminations

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

Airborne and Structure-borne Sound Insulation:
STC Target – 50• Current structure meets
criteria even without ceiling
IIC Target – 50• Current structure does not
meet criteriaS l i R l VCT • Solution: Replace VCT flooring for lab above with cork flooring
• New IIC is approx 73New IIC is approx. 73

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 hallcork flooring for lab above lecture hall
