Buildings

Facilities are structures which develop your planets. Each level of each building occupies one field of a planet. For a decent overview of what to build in the beginning, look at the Quick Start Guide.

See the Dependency Tree for the requirements to certain buildings.

It is possible to cancel the production of a building. When it is canceled, the resources that had been subtracted from the planet are given back. This can be used as a good method for saving resources. It is possible to save resources from plunder by first starting a production and then cancelling it when the danger passes.

Structures on a Planet or Moon can be also deconstructed by clicking on that structure from within the Facilities section.

Facilities cost
Buildings have a base cost in metal, crystal, and deuterium. The cost of a building depends on its level and the base cost of the specific building.

Calculator
There area some building calculators available that can help you determine building times and costs. See tools.

Buildings construction time
The base time taken to construct a level of a building depends on the amount of metal and crystal that level costs. Construction times are reduced by Robotic Factories and Nanite Factories (see this last page for the complete formula).

$$\mbox{Time(hours)} = {\frac {\mbox{Metal}+\mbox{Crystal}} {2500 \times (1+\mbox{Robotics Factory level}) \times 2^{\mbox{Nanite Factory Level}} \times \mbox{Universe Speed}}}$$

NOTE : It seems that at least in some universes this value needs to be multiplied by 2/(7 - Current level of the building constructed), until the said building is level 5. Can someone confirm this for all universes ?

NOTE : The additional reduction in time applies to the redesigned universes.
