⚠️ Eco v0.14 is coming — the next major update reworks upgrade modules, so some of these numbers will change. They reflect the current version. What’s changing →
  • Simpler tiers: the 1–4 tiered upgrades become a single Basic / Advanced / Modern upgrade each.
  • Permanent upgrades: a module placed in a workstation is permanent — no more swapping lower tiers out as you progress.
  • Power transitions: a module can change a station’s power type/draw (e.g. a Modern upgrade moves a sawmill from mechanical to electrical power).
  • Talent-integrated: modules now use the same bonus/talent system — any talent benefit (power, labor cost, recipe unlocks) can come from a module.
  • Cheaper to upgrade: with the multi-tier parts gone, fully upgrading a workstation costs significantly less.

We’ll update this calculator shortly after the update releases.

Notes

The Eco Book is a placeable decoration that adds a housing value of 1 to an enclosed room when placed on a surface. While it acts as a thematic nod to the game's research mechanics, its small 1x1x1 footprint makes it a minor furniture piece used to fill out space and meet object requirements for room scoring. Because furniture provides diminishing returns and is subject to category limits, players should use these books to add variety to their home's decor rather than spamming them, as a diverse selection of objects is required to maximize the housing XP bonus.
