strangely high zone air heat surface convection rate
I created a building without hvac system to see how room temperature change camparing to real-world data with openstudio 2.9 and sketchup 2017.but as you can see in picture.the zone air heat surface convection rate of room 104 105 204 205 is much higher comparing to other room. I checked the boundary condition and material all the rooms are very similar I wonder what makes this problem and how to fix this?
I suspect solar. If in the Northern Hemisphere, TZ201 seems to behave like a SSW corner room, while TZ202 may be a NNE corner room? The sharp spikes at the end of the day suggest west-facing glazing. There may be nothing there (to fix). I suggest you compare 2 zones (e.g. TZ104 vs TZ202): look up the evolution of surface temperatures vs solar gains. Might help.
Thank you! I 'll give it a try you mean TZ104 VS TZ 204?
Oops, sorry. I meant TZ202 (i.e. uneventful), vs TZ104 (where there's uncertainty). I corrected my initial comment.
