  • 29. EMERGENT PRACTICE• CO2 CAPTURECARBONIC ANHYDRASE ALGAE PRODUCTION
  • 30. PASSIVE HEAT AND COOL
  • 31. NIGHTSKY COOLING + MASS
  • 32. DISPLACEMENT VENTILATION
  • 33. EARTH TUBE + HEAT RECOVERY
  • 34. Displacement Ventilation Price PTU 2008
  • 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. 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. 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
