41. DV Characteristics
Ventilation 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

42. DV Characteristics
Ventilation 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

43. Applications
Healthcare
• 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
