Capturing Hidden Value in Local Assets - Gordon Gill, Partner at Adrian Smith + Gordon Gill

  1. 1. CHICAGO DECARBONIZATION PLAN Gordon Gill AIA
  2. 2. CO2 emissions 21% Source: Chicago Climate Action Plan
  3. 3. Buildings: 70% (3x Cars) Source: Chicago Climate Action Plan
  4. 4. 600M people/yr
  5. 5. 2015 Megacities Tokyo, 36 million New Delhi, 24 million Mumbai, 22 million Mexico City, 21 million São Paulo, 20 million © National Geographic
  6. 6. MASDAR HEADQUARTERS
  7. 7. New buildings 1% of stock
  8. 8. CATALYST FOR LARGER STUDY
  9. 9. 68,000,000 kwh/year =
  10. 10. THE STUDY AREA
  11. 11. The Chicago Loop Produces 3.9 Million Metric Tons of Carbon Each Year
  12. 12. PV FARM WIND FARM
  13. 13. 90 % of the square footage of buildings in the Chicago Loop was built before 1975. Much of this square footage has equipment and systems nearing the end of their life cycle. New buildings account for less than 1% of Chicago’s building stock. 10% 1% Carbon Use Land Use NEW CONSTRUCTION vs. EXISTING BUILDING STOCK
  14. 14. THE CHICAGO LOOP PARAMETRIC MODEL
  15. 15. DATA MODEL: BUILDING USE
  16. 16. DATA MODEL: BUILDING SIZE
  17. 17. DATA MODEL: TOTAL CARBON
  18. 18. DATA MODEL: ENERGY USE/ INTENSITY
  19. 19. DATA MODEL: BUILDING ERA
  20. 20. • Masonry with punched operable windows (25%- 50%) • MEP-not operating optimally • Narrow floor plates allow for natural light HERITAGE BUILDINGS: 1880- 1950 (PRE AIR CONDITIONING)
  21. 21. • Curtain wall systems • Glass percentage: 50% to 80% • Mechanical plants have large heating and cooling capacity to overcome internal load • Heat by light was common • Large floor plates with central core MID-CENTURY BUILDINGS: 1950-1975 ( PRE ENERGY EMBARGO)
  22. 22. POST ENERGY CRISIS: 1975-2000 • Curtain wall systems • Mirrored or dark tinted glass single or double pane • Introduction of thermal breaks • Induction/fan coil units at perimeter with interior air via ducted systems • Mechanical plants begin to use variable equipment • Lighting levels steadily reduced from 1970s levels • Large floor plates with central core
  23. 23. LEED AWARENESS BUILDINGS ERA: 2000- PRESENT • Curtain wall systems • Clearer glass with Low-E coatings or tint: double pane • VAV or FCU systems with less perimeter heat needed • Use of variable frequency pumps, drives and DDC controls • Lighting levels reduced to meet energy codes and LEED • Natural daylight and light controls • Large floor plates but shallower lease spans for natural light
  24. 24. CITY WITHIN A CITY – MIXED USE COMMUNITY District Cooling Basic NecessitiesSchools Parks
  25. 25. URBAN DENSITY VERSUS GASOLINE USAGE
  26. 26. MOBILITY NETWORK ANALYSIS
  27. 27. INTER-MODAL GREEN AXIS
  28. 28. MONROE INTER-MODAL GREEN AXIS
  29. 29. DECARBONIZATION… STEP-BY-STEP
  30. 30. + 30% Development < 50% Carbon 0.00 0.75 1.50 2.25 3.00 3.75 MMTCO2e Carbon Footprint Existing (MMTCO2e) Carbon Footprint New (MMTCO2e) Additional High Performance Office Decarbonization + Transit 00 25 50 75 100 2009 205 Mixed Use Office 50%
