Massing and Orientation for Heating

Heavy or massive objects like masonry can help improve thermal comfort as well as reduce peak heating and cooling demands in buildings.  They need to be designed into buildings such that they can charge and discharge thermal energy which often requires a temperature different between the thermal mass and their surroundings.  On exterior walls, they work best when coupled with insulation.  They, by themselves, are not good insulators.
