  1. University of DelawareCenter for the ArtsNewark, DE Karen Schulte Mechanical Option Spring 2006

  2. Presentation Outline • Project Information • Building Information • Existing Conditions • Redesign Goals • Mechanical Redesign • Structural Analysis • Acoustical Analysis • Conclusions • Acknowledgements • Questions

  3. Project Information • Location – Newark, DE • Building Use – Performing Arts Center • Delivery Method – Design-Bid-Build • Construction – May 2004 to June 2006 • 2nd of 3 bid package construction project

  4. Project Team • Owner – University of Delaware • Architect – Ayers Saint Gross • Construction Manager – Whiting Turner • MEP Engineer – Mueller Associates • Structural Engineer – McLaren Engineering Group • Civil Engineer – Tetra Tech • Acoustical Consultant – Kirkegaard Associates

  5. Building Information • 92,000 sq ft • Building uses • Recital Hall • Proscenium Theater • Orchestra Rehearsal Room • Theater Rehearsal room • Practice Rooms • 2” Open joint complete separation between structural systems

  6. Existing Conditions • Mechanical • 6 Air Handling Units • 4 constant volume single zone • 2 variable air volume • Chilled water and steam provided by the university

  7. Redesign Goals • Primary redesign goal • Implement an underfloor air distribution system in the Proscenium Theater • Secondary redesign goals • Improved indoor air quality • Reduced outdoor airflow • Reduced supply fan horsepower

  8. Underfloor Air Distribution • Conditioned air supplied from plenum • Pressurized Plenum • Passive Diffusers • Zero-Pressure Plenum • Active Diffusers • Warmer supply air temperatures • Stratification • Ceiling plenum return • Collection of contaminants • Ceiling lighting loads

  9. Mechanical Redesign Roof Barrier Ceiling Spot Booth Zone 4 Catwalk Zone 3 Zone 1 Stage Zone 2 Orchestra Pit

  10. Underfloor System Airflow – 14,200 cfm Cooling Coil Capacity – 315 Mbh Minimum OA % - 22% 20% overall reduction Supply Air Fan Static Pressure – 2.5in WG Overhead System Airflow – 7,900 cfm Cooling Coil Capacity – 420 Mbh Minimum OA % - 44% Supply Air Fan Static Pressure – 5.0in WG Mechanical Redesign

  11. Structural Analysis • First Level • Depress foundation and slab on grade 4’ • Elevated slab with grouted CMU blocks for support • Cut minimum amount of rebar for diffusers • Second Level • Elevated slab with grouted CMU blocks for support • Increase beam and column sizes to support increased weight of balcony • Cut minimum amount of rebar for diffusers

  12. 1st Level Structural Analysis

  13. 2nd Level Structural Analysis

  14. 2nd Level Structural Analysis

  15. Acoustical Analysis • Proscenium Theater • Acoustically Critical • RC 18-22 (N) • Underfloor Air Distribution • RC-17 (N) • NC-16

  16. Conclusions • Improved indoor air quality • Increased required airflow • Decreased minimum amount of outdoor air • Decreased cooling coil load • Increased coordination with concrete contractor and placement of diffusers • Meets acoustical criteria

  17. Acknowledgements • AE Faculty • AE Colleagues • Mueller Associates • Family • Friends (That means you, Spisis)
