Features in LCAbyg
Product
One tool for the whole LCA process: from calculation under EN 15978 to documentation for authorities and certification schemes.
You enter information about building elements, materials, and energy use. LCAbyg handles the calculations and gathers the results into figures and a report, ready to use.
Calculation
Calculation under EN 15978
All modules, A-D
Calculate the building's full life cycle: extraction of raw materials and manufacturing of materials, energy and resource use during operation and maintenance, and disposal or potential reuse.
9 environmental indicators
Climate impact and the remaining environmental indicators from EN 15978, calculated together for the whole project.
Climate requirements in BR18 and BR25
Full support for the climate requirements in the Danish Building Regulations, both before and after the tightened requirements.
DGNB and BREEAM
An approved calculation tool for Green Building Council Denmark's DGNB certification (2023 and 2025). LCAbyg 2023 is also approved for BREEAM Version 6 (and earlier), both International New Construction and Refurbishment and Fit-Out (RFO).
Data
Environmental data and libraries
Digital EPDs
Import digital EPDs directly into the project instead of entering data manually.
Standard data
Get started quickly with generic environmental data where an EPD doesn't exist yet.
Your own libraries
Build your own libraries of assemblies and building products, and reuse them across projects.
Shared company libraries Pro
Share assemblies and building products across the whole organization, so everyone calculates from the same basis.
Component import and export Pro
Move building elements and components in and out of projects, e.g. for reuse between project teams.
Collaboration
Collaborate on the project
Versioning Pro
Create multiple versions of the project and compare them, so you can see the effect of changes to the building model over time.
Free viewers
Colleagues and external parties can always see results and reports, and comment, at no extra cost.
Free external contributors
Invite consultants and other collaborators to enter quantities directly in the project via the quantity sheet tour, without needing a paid seat. Requires a Pro seat on the project.
Documentation
Reporting and export
Figures and overview
Results are automatically gathered into figures, so you can quickly see where in the building the impact lies.
Report for documentation
Generate a report ready for documentation to authorities and certification schemes.
Export to Excel
Take data further into your own analyses, templates, or handover, without re-entering it.
