tight building envelope
26
these types of building envelope make the building more drafty and uncomfortable, it also makes the building harder to regulate temperature levels. this creates higher chance of mold or mildew, and higher quantities of heated or cooled air are able to escape through leaks in the loose building envelope. this will increase energy bills along with negatively impacting the environment by releasing more greenhouse gases
loose building envelope
