SeaFury 🦜🍃 大家姐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
Onno (VK6FLAB)@SeaFury to add to this, we have a sprinkler on our roof, attached to a tap timer, set up for 10 seconds every 10 minutes or so, long enough to make the roof moist, short enough so it doesn't just run straight down the drain. You're aiming for the roof to evaporate the water. On really hot days I manually hose down the Sun facing wall every hour or so. Also close all the curtains, close all the doors to rooms that have an outside wall and drink lots of water.
