Show how your parts exchange helps reduce CO₂ emissions and conserve raw materials .
We integrate scientifically based environmental metrics into your platform.
Your users can seethe CO2 emissions avoided and raw materials saved right in their shopping cart.
✓ ReUse platforms
✓ Local building material exchanges
✓ Custom systems
What integration achieves
All four aspects are included in the full development package—no add-on modules, no hidden costs.
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—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
CO₂ & Raw Material Savings Through ReUse
The system calculates the emissions and resources saved through reuse—
compared to new production. Transparent, traceable, and easy to communicate.
- Absolute reduction in kg of CO₂
- RMI savings in kg of raw materials
- Clear and easy to understand
Shipping estimate included
Transport emissions (Phase A4) are factored in based on vehicle type and distance.
The overall balance remains complete and transparent.
- Delivery vans · Trucks · Truck-trailer combinations · Passenger cars, etc.
- Distance-based calculation (Phase A4)
- Emissions Factors and Raw Material Consumption
Communication & Certification
The results are based on recognized life cycle assessment data and are suitable for environmental communication,
proof of reuse, and CO₂-related analyses.
- EN 15804-compliant data set
- Proof of CO₂ Avoidance
- Can be used for communication and reporting
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,
biogenic sources, and land use during production and transportation—in kilograms of CO₂ equivalents.
A2 Transport to the Plant
A3 Manufacturing
A4 Transportation 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 for the manufacture
of a product—including all process and upstream materials.
A2 Transport to the Plant
A3 Manufacturing
A4 Transportation to the construction site
Grey emissions vs. operational emissions — when is reuse worthwhile?

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

With sustainable energy systems such as heat pumps, using old windows is advantageous.
With energy systems that produce high greenhouse gas emissions—such as gas or oil heating systems—
the disadvantage in terms of operating energy consumption may outweigh the benefits.
Where does the data come from?
All life cycle assessment data is based on recognized, publicly available sources
and is prepared in accordance with EN 15804 or is compatible with it.
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 data sets in accordance with EN 15804.
All GWP values and transport factors in the SURAP database have been reconciled with ÖKOBAUDAT
or derived directly from it.
BBSR Research Project
As part of a research program for the BBSR, we developed
and published key metrics for the RMI.
The SURAP database incorporates these research findings.
Transport emissions and use of raw materials
The emission factors and raw material use for Phase A4 are broken down
by vehicle type—e.g., delivery vans, trucks, and truck-trailer combinations.
Depending on the vehicle type and distance, the system automatically calculates transportation emissions
and reports them separately as Phase A4.
Generic Material Database
The SURAP Component Exchange database currently contains generic materials in seven categories—
prepared for reuse scenarios.
