Peoples struggling with hot buildings overnight, evaporation takes energy and will cool your building, even a light spray of water on your exterior (especially concrete/paving patios) will help cool you down overnight #BuildingScience
@SeaFury when we lived in Erskineville there were impromptu late night meetups on hot summer nights. People would wander out into the street and hose down their house exterior with the focus on the tin roof. Those old terrace houses used to get (and stay) hot and needed some help cooling down.
