What integration achieves

All four aspects are included in the full development package—no add-on modules, no hidden costs.

01

Life cycle assessment parameters specific to each material for each component

Each component is assigned the appropriate life cycle assessment parameters. Users select the material from the SURAP database—the GWP and resource use appear automatically in the entry.

  • GWP (kg CO₂ equivalent, A1–A3)
  • RMI Raw Material Input (kg of primary raw materials, A1–A3)
  • Generic SURAP dataset (created for ÖKOBAUDAT)
02

CO₂ & Raw Material Savings Through ReUse

The system calculates the emissions and resources saved through reuse—compared to manufacturing new products. Transparent, traceable, and easy to communicate.

  • Absolute reduction in kg of CO₂ (total & per unit)
  • RMI savings in kg of raw materials (total & per unit)
  • Clear and easy to understand
03

Shipping estimate included

Transport emissions (Phase A4) are factored in based on vehicle type and distance. The overall assessment remains complete and compliant with standards.

  • Delivery vans · Trucks · Truck-trailer combinations · Passenger cars, etc.
  • Distance-based calculation (Phase A4)
  • Emissions factors and raw material consumption from ÖKOBAUDAT
04

Communication & Certification

The results are based on data compliant with EN 15804 and are suitable for environmental reporting and CO₂ certificates in accordance with ISO 14064/14067.

  • Compliant with EN 15804 and ISO 14064/14067
  • Proof of CO₂ Avoidance
  • Eligible for funding and certification
Methodology & Indicators

What we measure

We evaluate two key indicators from life cycle assessment (LCA): GWP as a climate indicator and RMI as a raw material indicator.

GWP — Global Warming Potential

Indicator: kg CO₂ equivalent · Phases A1–A3, A4

The GWP (total) measures greenhouse gas emissions from fossil and biogenic sources and land use during production and transport—in kilograms of CO₂ equivalents.

A1 Raw Material ExtractionA2 Transport to the plantA3 ManufacturingA4 Transport to the construction site

RMI — Commodity Index

Indicator: kg of primary raw materials · Phases A1–A3, A4

The RMI tracks the total amount of raw materials extracted from nature to manufacture a product—including all process and upstream materials.

Additional practical example

Grey emissions vs. operational emissions — when is reuse worthwhile?

Not part of the integration · Further analysis

Reused windows often have higher U-values than new ones. The additional annual heating energy consumption may eventually outweigh the emissions saved during manufacturing—depending on the heating system.

Gas heating (~0.2 kg CO₂/kWh)~100 kg CO₂/year
Heat pump (~0.05 kg CO₂/kWh)~25 kg CO₂/year
Payback period
Gas heating: 480 ÷ 100 kg/year≈ 5 years
Heat pump: 480–25 kg/year≈ 19 years
Conclusion

In the case of sustainable energy systems such as heat pumps, using old windows can be advantageous. However, for energy systems with high greenhouse gas emissions (e.g., gas or oil heating systems), the higher operating energy consumption may outweigh the benefits.

Data source

Where does the data come from?

All life cycle assessment data is based on recognized, publicly available sources and has been prepared in accordance with EN 15804 or is compatible with it.

Primary source

ECOBAUDAT

ÖKOBAUDAT is the official German platform for life cycle assessment data on construction products, published by the BMWSB. It contains verified EPDs and generic datasets in accordance with EN 15804.

All GWP values and transport factors in the SURAP database have been cross-checked with ÖKOBAUDAT or derived directly from it.

BBSR Research Project

As part of a research program for the BBSR, we have developed and published characteristic values for the RMI.

The SURAP database incorporates these research findings.

Transport emissions and use of raw materials

The emission factors and raw material consumption for Phase A4 are broken down by vehicle type—e.g., delivery vans, trucks, and tractor-trailers.

Depending on the vehicle type and distance, the system automatically calculates the transport emissions and reports them separately as Phase A4.
