Så här säger våra kunder

“One Click LCA has been like a godsend to us with all the different types of databases and the graphic quality. As architects, we like to see things visually: all the material flows, all the LCA stages and how the material flows inform the different life cycle stages. Those graphics are pretty amazing in One Click LCA.”

Jude Chakraborty


“One Click LCA is great… There are both industry-average environmental product declarations (EPDs) and also a lot of manufacturer-specific EPDs, so it has a very large database. That’s a crucial factor in understanding the variation in impacts.”

Vanliga frågor

What data is available in One Click LCA? Does it include datasets from the U.S. and Canada?

One Click LCA integrates all U.S. and Canada EPDs. It contains more than 100k+ data points and integrates data from nearly all of the EPD platforms around the globe, including datasets from the U.S. and Canada, and uses TRACI 2.1.

Can One Click LCA help me to achieve Net Zero Goals?

Yes. Our Net Zero Tool allows you to quantify carbon savings, for example, renewable energy sources or carbon sequestration, as well as the carbon-emissions and offers a number for how much more you need to offset to comply with Net Zero Carbon definitions.

Can I use it with Revit and other BIM tools?

Yes. One Click LCA has a two-way integration with Revit and other tools like Rhino and Grasshopper.

The bidirectional nature of these integrations enables you to not only import BIM models and data into One Click LCA – but also to perform an embodied carbon assessment within Revit, Rhino, and Grasshopper.

Can I use One Click LCA for schematic design or even earlier?

You can. One Click LCA’s Carbon Designer 3D tool supports very early carbon optimisation and integrates with early design tools like Rhino and Grasshopper. 

Can I perform an LCA if I don’t have any material quantities?

Yes, the Building LCA tool allows you to perform life cycle assessments at any design stage. When no material quantities are available you can generate your own using the Carbon Designer 3D-verktyget. Det enda du behöver känna till är byggnadstyp, total golvyta och antal våningar. Resten kan du antingen anpassa eller så kan du använda standardvärden. Verktyget Carbon Designer genererar mängder material som kan importeras till din LCA-modell.

Do I need to know from which manufacturer my materials will come?

You don’t necessarily need to know from which vendor you’ll be procuring the materials. If you don’t have manufacturer specific information, you can use our extensive environmental impact dataset which covers all construction product types. We integrate specific manufacturer EPDs but also generic data so that you can always find the right match.

Can I use One Click LCA to create a baseline building for LEED?

Yes, you can.

Can I import data from BIM platforms and other software?

Yes, One Click LCA integrates with multiple software platforms to make it easier to upload your material quantities. Supported integrations include: Revit, Rhino and Grasshopper, Tekla Structures, Trimble Connect, IES-VE, Designer Builder and Excel.

How can I know which materials have the highest impacts?

We have a tool that shows the contribution of all the individual structures and materials and highlights those with higher emissions. This enables you to easily locate the components with the highest emissions.

Do I need EPDs for all the materials to be able to calculate an LCA?

When calculating a Life-Cycle Assessment you should always choose the best quality data available, which means that, if the material manufacturer you are planning to work with has product EPDs available following your calculation standard, you should use them. However, this might not be possible in all cases. If you are in an early design stage you may not yet know which manufacturer you are going to choose. When no exact information is available, you should use the second best option, which may mean similar products from another manufacturer, product category level EPD, or average LCA data for the product in question.

One Click LCA provides both an extensive database of EPDs and average data for the products. We also offer more detailed guidance to our clients to help them choose the most relevant datasets.
