Library
The collection of reusable constructions and building products. Opened via Library in the top menu.
The library overview
Section titled “The library overview”| Element | Meaning |
|---|---|
| Type | Official (blue), Organization (green) or Personal (purple) — see |
| who can do what below | |
| Owner | Who owns the library |
| Publish status | Published or Draft |

Create library
Section titled “Create library”Requires a name and an organization to own the library.
Content
Section titled “Content”Each library has five tabs:
| Tab | Content |
|---|---|
| Constructions | Composite building elements built from building products |
| Building products | Individual building products, energy sources, fuels etc. |
| Modules | — |
| Energy supply | Energy sources for operation and construction site |
| Fuel supply | Fuels for transport and construction site |
Each tab has two views: Overview (card view) and Data (table view).
Guide: new building product
Section titled “Guide: new building product”The creation wizard has up to five steps: Type → Details (name, unit, classification) → Structure (constructions only) → Emissions (modules and indicators) → Source (version, EPD source). Steps 3 and 4 can be skipped and completed later from the product’s detail page.
Building product types and what they’re used for:
| Type | Used for |
|---|---|
| Building material | The building model — real life cycle modules (A1-A3, C, D) and lifespan |
| Energy | Electricity, heat, water — used in Operation (B6), construction site (A5) and transport (A4) |
| Fuel | Diesel, petrol, HVO etc. — used on the construction site and in detailed transport |
| Transport mode | Truck, train, ship, plane — factor per kg·km, detailed transport |
| Transport standard | Standard transport scenario — factor per kg of building product |
| Waste | Waste fractions on the construction site — modules A1-A3 + C3 + C4 |
Emissions are entered either as a single fixed factor or factor per year (interpolated linearly between years; the nearest year is used outside the range).
Guide: new construction
Section titled “Guide: new construction”Constructions are built up from sub-constructions and/or building products, each with its own quantity.
Import
Section titled “Import”A gen_dk ZIP file with generic Danish reference data can be imported in one go via the Import function. The content (constructions, products, modules and energy supplies) is added to the library as ordinary library content.
The same Import function has an Import element card that takes a .lb5elm element file (or
a .json file). The element’s constructions are added with their building products and modules, and
you choose whether the outermost building element is imported as a group (recommended) or as one
grouping construction. See How to import an element file into a library.
Settings
Section titled “Settings”A library’s settings cover name, type, owner, version, publish status and calculation modes. A library only shows up in a project’s library picker if it is both published and has at least one calculation mode selected that matches the project. So choose the calculation mode at the same time as you publish, see How to publish a library.
Who can do what
Section titled “Who can do what”| Type | Can see | Can edit |
|---|---|---|
