Building Efficiency Rating
Compare and evaluate special buildings based on customized efficiency criteria.

Compare special buildings based on daily output per tile, using your own priorities and expectations. This tool helps you determine which buildings are most efficient for your city layout and strategic goals.
The Building Efficiency Rating tool is intended as a guidance aid. Some resource types may not yet be fully supported, which can result in incomplete or inaccurate building evaluations.

Evaluation Method
The efficiency score is calculated by comparing each building's actual output against your expected daily value per tile.
Score = (Output ÷ Expected value) ÷ (Tiles + 1 where road is required) × 100 (e.g., 20 FP ÷ 10 FP expected ÷ 2 tiles = 1 × 100 = Score: 100)
Settings
The Settings panel allows you to define what you expect your buildings to produce. These values are essential for calculating the efficiency score for each building.

The settings menu is structured as follows:
Title bar with a Configuration menu
Settings Table with two columns:
Enabled: A checkbox that includes or excludes the resource from the efficiency calculation and overview.
Expected daily production/tile: A numeric field that defines your desired production rate per tile, per day.
Buttons: At the bottom of the panel
Result: Apply the configured expectations and return to the comparison view.
Reset to default: Clears your custom values and reverts to default settings.

FAQ
Q: What does the efficiency score represent? A: It quantifies how well a building meets your configured expectations per tile.
Q: Why are some values fractional (e.g., 4.5 FP)? A: These represent average daily production across chance-based outcomes.
Q: Can I compare buildings I don’t have yet? A: Yes, use the Add Building button to select from a full list of special buildings.
Q: Can I set zero for a resource I don’t care about? A: Yes. You can set its expected value to 0 to include it in ranking table but exclude it from the scoring.
Q: What’s the “FSP Calculator”? A: This defines the value of FSP kits, helping estimate the worth of FSP kit fragment.
Q: Can I search by partial name? A: Yes. The search bar supports partial matching.
Q: Will buildings I add affect the main score table? A: Yes. Once added, they are listed and scored in the main ranking view using your current expectations.
