Is it possible to change the color of the exterior wall of the building?

hello.

I would like to compare the difference in energy load depending on the color of the building’s exterior walls.

However, I don’t think there is an element to adjust R, G, and B in HB-Energy (there seems to be one in HB-Radiance).

Is this kind of research possible?

Hi @imj06050215,

You will have to translate the colour and material values to the absorption factors of the material.
Colour tell you only something about visual absorption.

thank you

I will conduct research using the method you mentioned.
