[EnergyPlus_Support] Re: FangerPPD acceptable levels

i like Linda's comment 'leave it up to the user to determine acceptability' Prof Fanger did a lot of his work in Denmark, or regions that are far away from the equator. There or other indices, from others who did a lot of work in tropical countries notably Koenigsberger. Besides different climate classifications in different parts of Australia, comfort in its residential buildings depends on also whether there is a fan, three sizes available in its FirstRate software, or not. Recently ASHRAE, particularly 55, has emphasized on the effects of air movement and EnergyPlus has Adaptive Thermal Comfort index. ooi
