    • PASSIVE HEAT AND COOL
    • NIGHTSKY COOLING + MASS
    • DISPLACEMENT VENTILATION
    • EARTH TUBE + HEAT RECOVERY
    • Displacement Ventilation Price PTU 2008
    • 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
    • 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
    • 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
