| Dec 21, 2023 at 21:24 | comment | added | zed | Thanks, this answer was helpful to understand what was wrong with my calculation and intuitions. Observing that the inside temp rises slowly on a hot day, I figured that I could ignore the effects of the environment over the time scale of minutes. I thought of the walls as a shield which blocks a high % of the incoming energy. I should think of the walls as a reservoir, not just a shield. If the AC blasts the room full of cool air, the walls could quickly return the air to a higher temp. On the bright side, I can worry less about briefly opening the door and letting cold air out. | |

Good materials would be cork, fire rated carpet, non foam based soundproofing panels (hemp, rockwool, etc) for example. Or just waste the energy and heat/cool the drywall, but put linoleum or carpet on the floor if it's a slab. If it's wood then it's okay. Lino is much better for a garage though. | |
