Overview of features
Welcome to Reduzer!
This page provides a high-level overview of the key features and capabilities of the platform. Reduzer is a powerful Life Cycle Assessment (LCA) tool designed to help you calculate and analyze the environmental impact of your construction projects, with a primary focus on greenhouse gas emissions.

Core Calculation Engine
At its heart, Reduzer provides a robust and transparent calculation engine based on established standards like NS 3720 and EN 15978.
TIP🍀
Choose from various predefined calculation schemes (e.g., TEK17, BREEAM, FutureBuilt) that determine which life cycle stages (A1-D) are included in your results. You can also create custom schemes to fit specific project requirements.
GWP Calculation
Reduzer primarily uses GWP-IOBC (Global Warming Potential - Instantaneous Oxidation of Biogenic Carbon) for calculations, ensuring biogenic carbon is properly accounted for. GWP-fossil is used as an alternative when necessary.
Life Cycle Stages: The platform systematically calculates emissions across all relevant stages:
A1-A3 (Production)
Based on Environmental Product Declarations (EPDs). A 25% markup is automatically applied to generic data in certain >schemes like TEK17.
A4 (Transport to Site)
Calculated using either the precise production location from an EPD or typical transport distances (Local, Regional, >Standard, etc.), which are fully customizable.
B-Phases (In Use)
Includes calculations for B1 (carbonation of concrete), B2 (maintenance), and B4 (replacements), based on the product's >service life.
C-Phases (End of Life)
Transport to waste handling (C2) and other end-of-life scenarios are calculated based on project settings and conservative >EOL scenarios.
Project & Version Management
Reduzer is built for collaboration and iterative design, allowing you to manage complex projects with ease.
Hierarchical Structure
Organize your work into Projects, Objects (Buildings), and Versions. This structure allows you to test different designs, material choices, or scenarios within the same project.
Multiple Ways to Add Materials:
Automodel
Quickly generate a building model with materials based on standard typologies (e.g., office, residential). Ideal for >early-phase estimates.
Excel Import
Use a template to bulk-upload your material list.
BIM Connection
Connect your Archicad or Revit model via Speckle to import quantities directly.
Manual Entry
Create an empty version and add products and components from the libraries manually.
Advanced Comparison Tools
Compare results between different versions within a building or between different buildings in a project to make informed decisions.
Collaboration: Invite team members to your project with distinct roles (Owner, Editor, Viewer) to control access and editing rights.
Automodel for Early-Phase Analysis
The Automodel is a powerful feature for generating quick, data-driven building models without needing a detailed design.
Typology-Based
Select a building typology (e.g., school, small house) and define key parameters like gross floor area, number of floors, and structural system.
Parametric Design
The Automodel calculates material quantities based on your inputs. Adjusting a parameter like the window-to-wall ratio will automatically update the related material quantities.
Foundation for Detail
The version created by the Automodel can be refined by swapping generic materials with specific EPDs as your project develops.
BIM Integration
For projects with developed designs, Reduzer integrates with your BIM workflow.
Speckle Connection
Upload your Revit or Archicad model to a Speckle stream and connect it to a version in Reduzer.
Quantity Take-Off
Reduzer imports the building elements and their quantities from your model.
Component Mapping
Assign components from Reduzer’s libraries (e.g., "Exterior Wall - Wood Cladding") to the corresponding elements from your BIM model to calculate emissions. Mappings can be saved and reused.
Comprehensive Data Libraries
Reduzer's strength comes from its extensive and well-managed data libraries.
Product Library
Access a global library of thousands of specific EPDs. You can also add EPDs to your private "My Products" or shared "Company" libraries.
Component Library
Use pre-defined, generic building components (like walls, floors) which can be customized and saved to your personal or company library.
Activity Library
Find data related to energy use (for phases A5, B6, C1) and transportation (B8), including a detailed database of district heating sources in Norway.
Circularity & Reusability Features
Reduzer includes dedicated features for analyzing and promoting circular economy principles.
Product Origin
Define a product's origin as New, Reused, Existing kept, or Existing waste. Reused materials automatically receive a standard 80% emission reduction in A1-A3.
End-of-Life Scenarios
Set custom reusability percentages for products at their end of life.
Circularity Reporting
The results section includes specific graphs and data on the circularity of material flows, helping you track metrics for schemes like FutureBuilt.
Reporting and Exporting
Clearly communicate your results with Reduzer’s reporting tools.
Dynamic Reports
Generate a comprehensive web-based report for any version, which can be shared via a link or downloaded as a PDF.
Data Export
Export your full inventory list, subparts, or results to Excel for custom analysis, creating your own charts, or for use in other tools like the BREEAM Mat 01 calculator.
