33
``` passive cooling: stack ventilation pools of water thermal mass cross ventilation ```
- stack ventilation: cool air drawn in down low, vented out up top - pools of water: cool hot arid climates through evaporation - thermal mass: heat is absorbed and stored during day - cross-ventilation: increases air movement, cools hot-humid climates
