Residential zones can be specialized into "Self-Sufficient Buildings". This was added via the "Green Cities" DLC, and is not available without it. To specialize an area, draw a district over the area to be affected and apply the desired specialization.
Generic[edit | edit source]
No specialization is the default, and results in standard generic residential buildings. Existing specializations can be removed with the "No Residential Specialization" button in the specialization menu, or by right clicking a specialized district with the specialization tool. This will result in existing buildings disappearing, and then regrowing as generic residential buildings if there is sufficient demand.
Self-Sufficient Buildings[edit | edit source]
|Available only with the Green Cities DLC enabled.|
The "Self-Sufficient Buildings" residential specialization creates buildings that recycle their waste and produce energy with solar panels and by other means. Beneficially they consume 30% less energy and produce 30% less garbage as compared to the standard residential buildings. Due to their lower dependence on city services, they generate 30% less tax income.
The "Self-Sufficient Buildings" specialization becomes available at the "Worthy Village" milestone.
