The discussion that @Mugen87 linked above is the right approach here. I suggest that you look over it again. The key phrases you should be taking from it to help in your research are “texture baking” and “light maps”.

Maybe the missing piece is Someone gave you an asset - house_without_textures_and_light_maps You need to be in a situation: Someone gave you an asset - house_with_light_maps The image you linked is not something that can be generated with three.js.
