I’m currently working on the thermal optimization of a 5-zone single-family residential building. Since my goal is to optimize the whole building’s thermal comfort (using Galapagos), I’m planning to use the average of all 5 zones results as my objective function to be optimized. I intend to use the ASHRAE 55 adaptive comfort method to asses whether the zones are comfortable or not, however, I don’t know which is the best Ladybug component I should use to get the average comfort for my building. As far as I know, there are basically two options:
Simulate through ModelToOSM, assess thermal comfort using the LB Adaptive Comfort component and get the zones average; or
In my opinion, the first option seems to be the faster one, while the second looks more precise, although taking more computer power simulate each one of the sensor points. Another guess is that both approaches could be leading to the same overall average.
Both are valid workflows and are suitable to assess adaptive thermal comfort. The only difference is that the first method will only give you the comfort in the center of the room when there isn’t any sun falling onto the occupant. The Adaptive Map component can be used to show how the comfort varies throughout the Room and it will account for sun falling on occupants closer to the windows.
Hi @chris ,
Sorry to bring you back to this topic. I was just comparing these 2 workflows in my model (Rhino 8), but the results are very different between each other. It makes sense in rooms like a greenhouse, but it doesn’t make sense to have so different percentages in rooms like a garage or a bathroom where the sun doesn’t fall onto the occupant. Do you have any clue? As it makes me doubt what’s the simulation that is closer to reality.
I realized about the following: for the 1st workflow, the outputs of LB Comfort Statistics say “the percent of time…”, while for the 2nd workflow, the outputs of HB Adaptive Comfort Map say “the percentage of occupied time…”. I tried using an HB Program Type and assigning 100% occupancy time to the Garage, and while the results change more for the 2nd workflow, the difference between both workflows remains very big.
Thank you so much in advance!
