Hi all
I am running an energy simulation for a three-story office building. I want to know the avg. air temperatures in each of the thermal zone as is i.e. without conditioning. The “is conditioned” is thus set to false. A few trees are there in the context.
The “color zones” for air temp. from “read EP result” component show that the middle floors have highest temp. Should it not be the upper floors?
Please see!
“theoretically” and tentative on a number of things:
the middle floors have the least amount of exposed surface area; and the most inter-zonal / inter-floor adjacent faces; therefore more opertunity to heat gain, and less opertunity for heat loss via surface convection/conduction to the enviornment; so it to me; would make sense that the middle floors would be a few degrees hotter without conditioning.
TLDR/IMO:
I don’t personally see anything wrong with what is being displayed; it all makes sense in my eye
Thank you so much for your response Trevor.
I would like to raise a few quick points here.
I agree to your explanation, basis the concept of adjacent surfaces, particularly in the context of honeybee. However, most research says that top floors due to maximum exposed area tend to have highest temperature (not considering effect of wind).
The middle floor though will gain heat from lower and top floor via conduction, but I feel that it will be lesser compared to total heat gains in top floor via radiation and conduction.
Even if middle has higher temperature, the top floor should still show temperatures considerably different from lower floor (given the exposure levels)
If you use the peak loads component, and or run an annual loads run you will likely have the data to understand why you are getting the results you are getting I think.
