  11. 11. VIP AND VIG
  12. 12. ADVANCED GLAZING
  13. 13. THERMAL COMFORT
  14. 14. THERMAL COMFORT
  15. 15. PSYCHROMETRICS
  16. 16. CONVENTIONAL SYSTEMS• VARIABLE AIR VOLUME SYSTEM
  17. 17. CONVENTIONAL SYSTEMS• TERMINAL REHEAT, CONSTANT AIR VOLUME
  18. 18. CONVENTIONAL SYSTEMS• DUAL DUCT SYSTEM CONVENTIONAL SYSTEMS
  19. 19. CONVENTIONAL SYSTEMSPERIMETER INDUCTION CHILLED BEAM
  20. 20. CURRENT BEST PRACTICE• DEDICATED OUTDOOR AIR SUPPLY• 100% OA WITH RADIANT HEAT/COOL
  21. 21. CURRENT BEST PRACTICEDISPLACEMENT VENTILATION UNDERFLOOR SUPPLY
  22. 22. CURRENT BEST PRACTICEAIR COUPLED THERMAL MASS
  23. 23. CURRENT BEST PRACTICEDISPLACEMENT VENTILATION
  24. 24. LOW E CEILINGS
  25. 25. CURRENT BEST PRACTICE• DUAL DESICCANT ERV
  26. 26. LIQUID DESICCANT COOLINGVAN ZYL 2 CYCLE USES CaCl2 @ COP >2
  27. 27. CURRENT BEST PRACTICE
  28. 28. EMERGENT PRACTICE• BIOFILTRATION
  29. 29. EMERGENT PRACTICE• CO2 CAPTURECARBONIC ANHYDRASE ALGAE PRODUCTION
  30. 30. PASSIVE HEAT AND COOL
  31. 31. NIGHTSKY COOLING + MASS
  32. 32. DISPLACEMENT VENTILATION
  33. 33. EARTH TUBE + HEAT RECOVERY
  34. 34. Displacement Ventilation Price PTU 2008
  35. 35. DV CharacteristicsVentilation Effectiveness• Outdoor Air requirements (ASHRAE Standard 62- 2004) – Requirement = (Occupant/Space Requirement)/(Ez) – OHAD = 100/1.0 = 100 CFM – DV = 100/1.2 = 80 CFM• 20% Savings on OA requirements Source ASHRAE
  36. 36. DV CharacteristicsVentilation Effectiveness• Measure of Contaminants in Occupied Zone compared to Return Air• Mixed Systems < 1.0• DV Systems > 1.0• Potential Reduction for outdoor air requirement under ASHRAE 62-2004 C Exhaust Ec = COccupant
  37. 37. ApplicationsHealthcare• New research into Healthcare and DV – Show applications in patient rooms, waiting areas, admittance, non- critical care spaces• Superior comfort levels• Improved contaminant removal – Significant reduction in infectious transmission through airborne containments
