73 NATURAL VENTILATION Wind and Stack wind driven flow ideal exhaust 0.55 for perpendicular wind 0.3 for diagonal wind interpolated for in-between angles source and more info: EnergyPlus Input Output Reference DIVA DAY TORONTO ARCHSIM

74 NATURAL VENTILATION Airflow network Can do Air flow through exterior or interzone surfaces Different models for horizontal vertical and tilted surfs Buoyancy effects and wind pressure. Wind direction and surface orientation dependent. Bi-directional flow through large openings Can not do Air circulation and/or air temperature stratification within a thermal zone. For example, you should not try to divide a high space, such as an atrium, into subzones separated by source and more info: EnergyPlus Input Output Reference DIVA DAY TORONTO ARCHSIM
