Concerns

• Head Room – Floor to floor heights?

• Location of MEP room

• Choice of a centralized vs distributed system

Construction IssuesMEP Issues

• Cores used for risers with diameter of 24”

• Distribution at center brings used air down

• Fresh air distributed through the lateral cores.

• Duct sizes

• typical rooms 14”

Raised Floor System – Benefits and Disadvantages

• Improved efficiency

• More effective

• Allows great deal of flexibility

• 1.25 times cost of conventional system

Team Process

A E C

Working together, we were able to design a building that:• Closely meets the program requirements• Functions well as a learning facility• Responds to the site• Has a fairly low-life cycle cost• Is adaptable to meet changing needs

Conclusion

A E C

• Early design commitments• Early consideration of MEP and structural systems • Cross-disciplinary design contribution• Synchronous communication• Common AutoCAD drawing
