Buildings are structures constructed on the surface of a planet. One building may be constructed per tile, either increasing the tile's productivity when it is worked by a population unit or providing some other bonus. They cost minerals to build and energy each month to maintain.
Buildings either augment or replace the existing production of a tile, depending on whether If a building's output is the same as the tile's natural resource, it will increase production of that resource. However, if the natural and artificial output don't match, the building takes precedence and the natural output stops. For example, if a tile produces one mineral and two food, building a Basic Science Lab I on it would cause both productions to end and only the science output from the building will be produced. If a Hydroponics Farm I is constructed on the same tile only the food would remain of the natural production. A Hydroponics Farm I on the aforementioned tile would result in 4 food per month, while a Mining Network I on that tile would result in 3 minerals per month and no food.
Planet-wide and empire-wide effects of buildings occur regardless of whether the tile aligns with the building.
