Night ventilation of thermal mass works best
WebbMost systems which utilise thermal mass are designed so that, at night, cool air is introduced to ventilate the building. This flows across surfaces which have absorbed heat during the day, purging the energy, cooling … WebbDuring the night as a building cools the stored heat energy is then released into the building interior space reducing the heating demand. Thermal mass is most beneficial in climates where there is a large …
