5. Site – Existing Conditions View looking East View looking South

7. LEED Accreditation • LEED Certification Levels: • Certified (40-49) • Silver (50-59) • Gold (60-79) • Platinum (80-110) • Minimum LEED Certification at UT: • Silver • Plan to Achieve a Minimum of Gold Level • Set the standard for “Energy and Innovation”

8. LEED Accreditation LEED 2009 New Construction Design Manual • Checklists • Sustainable Sites • Water Efficiency • Energy & Atmosphere • Materials & Resources • Indoor Environmental Quality • Innovation & Design Process • Regional Priority Credits • Detailed Credit Info • Intent, Requirements, Potential Strategies

9. LEED Project Checklist Example Section-Sustainable Sites • Current analysis achieves 81 points total (Platinum Rating) • Point total achieved through combined civil, mechanical, and electrical design groups

10. LEED Accreditation • Detailed LEED Strategies Plan • Provide specific details for credits to be achieved Existing Hybrid Sign

11. Sustainable Technologies • Solar Panels • Geothermal Heating/Cooling • Rain Water Collection • Green Roof

12. Solar Panels • Utilize a large grid-tied system • Allow energy to be sold into the grid at low consumption times • Avoid large battery bank; making the system easier to maintain and more eco-friendly • Wirelessly monitor through a PC/Website • 36 kW tower system consisting of 6 inverters and 180 panels

13. Geothermal Heating/Cooling • Vertical closed-loop system was developed by the mechanical group. • Reduce the Heating/Coolingcosts and earn LEED credits

14. Rainwater Collection • Rainwater to be collected only from the main roof • 20,000 Gal. tank proposed • Irrigation to be north and west of building (Hatched area on following slide) • No potable water will be needed for irrigation

16. Green Roof • Located on top of auditorium. Entranceon 3rd floor of main building • Green roof will feature extensivevegetation • Extensive vegetation is lighter andrequires less soil, therebyreducing the load (saturated load approximately 34 psf) • Will feature walkways and tablesfor occupants to enjoy

17. Research Labs • Civil Experiments • Pervious Pavements • Green Roofs • Mechanical Experiments • Electric Motors • Hydrogen Fuel Powered Engines • Green Heating and Cooling Systems • Electrical Experiments • Smart Grid • Wind Turbines • Solar Panels • Storm Water Collection • LEED Design Techniques

18. Interior Concept

19. Exterior Plan • Utilize Kalwall TranslucentDaylighting Systems • Minimize need for artificial light • Panels provide low solar heat gain and high insulation values • Made from 20% recycled content

20. Exterior Plan – Glass • Strategically use windows to keep occupants in touch with outside world while providing natural light

21. Floor Layout

27. **Entrance windows and roof not shown for clarity

28. Structural Design • Structural Steel Frame • Procedures followed: • Load and Resistance Factored Design (LRFD) • American Society of Civil Engineers (ASCE) Version 7 • American Institute of Steel Construction (AISC) • Complete SAP 2000 v12 Analysis • Hand Calculations for Typical Members/Sections • Floor Beams • Interior/Exterior Girders • Columns • Auditorium Roof • Main Roof • Wind Bracing • Foundation

29. Loads • 1st Floor • Dead = 200 psf • 2nd & 3rd Floors: • Dead = 100 psf • Auditorium Green Roof • Dead = 40 psf • Snow = 20 psf • Main Roof • Dead = 40 psf • Snow = 20 psf • Live = 80 psf • Live = 80 psf • Live = 80 psf • Roof Live = 20 psf

30. SAP 2000

31. Floor Beams • Located on the 2nd and 3rd floors • Designed to support metal decking withconcrete cover • Uniform distributed load on entire beam • Max load case: 1.2D + 1.6L • The beam was designed for the maximum bending moment • Allowable deflection controlled beam selection

32. Interior / Exterior Girders • Designed using end reactions from connecting floor beams • Point loads at girder/floor beam connections • Max load case: 1.2D + 1.6L + .5S • 2 Typical interior and 2 exterior were designed • Allowable deflection controlled girder selection

33. Columns • Designed using axial loading from SAP 2000 analysis – Max load: 1.2D + 1.6L + .5S • 3 Typical columns (Locations on next slide) • Main exterior (Red) • Main interior (Blue) • Auditorium (Yellow) • Maximum axial load controlled column selection

34. N

35. Auditorium Green Roof • Designed to support saturated green roof • Distributed load on entire joist • Max load case: 1.2D + 1.6L + .5S • Max span: 85 feet • Long span LH series roof joist • Allowable distributed load controlled selection

36. Main Roof System • Designed using supported tributary area • Distributed load on entire joist • Max load case: 1.2D + 1.6L + .5S • Max span joist: 70’ • Max span joist girder: 34’ • 2 typical joists and 1 joist girder designed • Built-up-roof components (per UT guidelines) • Metal decking • SEBS base sheet • Type 6 glass felts

37. Main Wind Force Resisting System • Based on ASCE 7 provisions • Wind Load Factor = 1.6 (LRFD Combinations) • 3 wind braces to resist East-West winds • 2 wind braces to resist North-South winds • 3 designs to accommodate structural differences in the building

38. Wind Brace Locations N

39. Typical Wind Brace

40. Foundation Selection • Loadings obtained from SAP Analysis of the building • Pad footings with integrated auger cast piles were selected • Pad footings and piles required less concrete than strip or mat foundations • The piles transmit some load to more stable clays below grade • Four typical pad footings were designed to increase efficiency

41. Footing Design • Soil info was obtained from boring logs of Scott Park • Estimated bearing capacity of 4 kips/sq ft for the soil • Foundation size and number of piles determined by loading and bearing capacity • Designed for one and two way shear to obtain sufficient depth for the reinforcing steel of the foundation
