Everything You Need for Project Control

Ratu Costs and CO₂e

A building-element-based cost and CO₂e calculation service that allows you to compare alternatives based on cost, emissions, and construction duration.

With the service, you can:

  • Calculate project costs at the building-element level
  • Compare the impact of material choices on CO₂e emissions
  • Utilize ready-made model projects
  • Modify calculations transparently according to your needs
  • Transfer data directly to the Product Information Carbon Calculator

Space Calculation Module

Accelerate Project Planning and Compare Alternatives Before Costs Are Locked In

The Space Calculation Module helps you quickly assess how different design solutions affect costs and project scope.

You can examine, for example:

  • The impact of building shape on costs
  • The effects of the number of floors
  • The impact of apartment/unit distribution
  • The budget implications of alternative solutions

When the target cost is known early, it becomes easier to guide design in the right direction.
