Temperature System

Temperature
Temperature is dependent on rooms forming. If not the base temperature of an area is used. Temperature naturally goes down in higher Z-levels and up deep underground. The larger the room the slower it losses or gains heat.
 * Doors and grates conduct heat between rooms connected to them. Grates conduct heat faster and both conduct heat much faster when open.
 * Walls (depending on the material of the wall). Multiple layers of wall decrease heat transfer. The surface area of the walls also affects heat transfer.
 * Creatures inside a room increase its temperature slowly.
 * Certain buildings increase heat while running.
 * The fireplace and campfire burn fuel to increase temperature.
 * The evaporation cooler uses fresh water to decrease temperature.

Temperature display can be changed from metric to imperial in the options.

Effects

 * Creatures take damage if temperature is too extreme.
 * Colonists get unhappy if temperature is too hot or cold. Wearing clothing can help mitigate cold.
 * Plants stop growing if temperature is too low.
