Hey [@Community](https://community.realtimelca.com/groups/community) 👋

This one’s been building up — the ability to clone public constructions from other organisations, biogenic content parameters in the material editor, and an in-app feedback tool. Oh, and we squashed a _lot_ of bugs. Let’s dig in:

* * *

### 🔁 Clone Public Constructions from Other Organisations

It’s now possible to clone a public construction from another organisation directly into your own. The original source is tracked behind the scenes, so you always know where a construction came from — and your version is fully yours to edit.

* * *

### 🧬 Biogenic Content Parameters

Materials that contain biogenic carbon can now have their **biogenic parameters** (product and packaging) entered directly in the material editor — when creating, editing, or cloning a material. The field sits just above the LCA indicators, right where it makes sense.

* * *

### 💬 In-App Feedback

There’s now a **feedback button** built into the app. Spot something off? Have a suggestion? You can send it without leaving RTLCA. We’re listening.

* * *

### ⚡ B6 energy guidance for early-stage projects

When setting up operational energy (B6), the platform now shows recommended maximum consumption values based on your building typology, along with a note on the Danish energy frame limits (30 or 40 + 1000/A kWh/m²/year). A reminder is also shown that a real energy frame calculation is required at project completion.

* * *

### 🐛 Bug Fixes

- 🏗 Fixed window and door total areas breaking after the Speckle v3.15 connector update. Both area parsing paths are now aligned with the new naming conventions.
- 📐 Fixed columns not exporting their length in meters from Speckle models.
- 🔧 Fixed a store initialisation issue that prevented models from being added when editing an existing building project.
- 🗂 Fixed collection filtering not being applied correctly against the database — collections now filter as expected in the mapping view.
- 🔍 Fixed the datasource filter in the material mapping library occasionally showing `undefined` values instead of real datasource names.
- ✏ Fixed editing a preferred unit value clearing the field when extending an existing number (e.g., `100` → `100.5`).
- ⚡ Fixed the mapping progress bar not updating automatically after performing a mapping action — it now reflects the new percentage without a page refresh.
- 🏷 Fixed classification codes not appearing in the material mapping modal, even though the data was present in the backend.
- 🇩🇰 Fixed reference areas not being selectable when using the **Low Emission (2025)** calculation type.
- 🇩🇰 Fixed the transport setup step showing incorrectly during project creation/editing for Low Emission (2025) projects.
- 📋 Fixed an error that allowed B6 energy data to be submitted without a consumption value — validation now catches this before continuing.
- 🏷 Fixed library filters not persisting for materials when switching between the materials and constructions tabs.
- 🤖 Fixed automapping failing on a construction model when an architect model had already been automapped in the same project.
- 📊 Fixed emissions showing as `0` in the project breakdown Excel export.

Plenty in this release — both new capabilities and a solid round of polish. As always, questions and feedback are welcome in the [community](https://community.realtimelca.com/). Keep building! 🌱

Hi guys

Great work with the release! Looking forward to being able to edit LCAbyg constructions 🤩🎉

Might I suggest, that you add an image like this is the description you’ve made in the `Operational Energy Use (B6)` tab, with a little description of whether you should enter the total PV production (3) or only the total PV production - 25/1,9, like we do in LCAbyg.

This would be very neat 😁🙏

That would address this topic:

> Hi guys The help note in the Operational Energy Use (B6) tab on RTLCA, it says that this value should be maximum 25 kWh/m2/year However, in LCAbyg you only enter whatever electricity production isn’t included in the Be18 calculation. So BR18 only allows max 25 kWh/m2/year, which in primary energy use converts to 13,2 kWh/m2/year. So in LCAbyg, you only add whatever eletricity production is above 13,2 kWh/m2/year. This is because the electricity production (max 13,2) has already been…
