I don't see anything particularly wrong with the charts. Trees have two effects on the building: (1) shading of solar radiation, and (2) wind-shielding on the wind speed. The latter in turn reduces the infiltration as well as conductive heat transfer by increasing the exterior air-film resistance. If you are still doubtful, you can check the solar fraction due to the shading (should be low during the summer and higher but not 1.00 during the winter) as well as the local wind speed.Joe

Hi.
The x axis shows the month and the y axis shows the time. I understand this year's change well so I am using this graph.

What's the X-axis on the two plots? I assume the Y-axis is the Hour of Day. Also, what temperature is being plotted?

Hi.
I am interested in how deciduous trees will affect room temperature. So
I simulated with EnergyPlus using a simple model.
I am at a loss for results I can not understand. I did two kinds of
calculations. One is the case without deciduous trees and the other one
is deciduous trees.
Then the room temperature in January resulting from the absence of
deciduous trees and the room temperature in January with deciduous trees
are greatly different. I thought that room temperature in January was
almost equal.
I will attach two results and an idf file. Please tell us where you are
mistaken.
