That's weird, I usually have large gardens (now in Hydroponic planters, because I got tired of sprinklers not watering my plants), upgrade basically everything in the house, eco-green floor/wall covering, dew collectors/wind turbines etc. And only the house my sims live in is green. The rest of the neighbourhood (4 houses, currently Lani St. Taz, Sulani) are neutral.
So far, no sunrays/aurora in my current house. Would very much like to disable it too, wherever I see them. They are very "intrusive".
