LCA plugin Finally here :) DesignLCA

Thomas Nymann



Graphisoft Center Danmark just released a public beta version of DesignLCA, a plugin to AC 26 that facilitates Eco designer star, in order to calculate a projects CO2 footprint throughout a given period of time (CO2eq/m2/anno)


DesignLCA calculates the "Global Warming Potential" as an "Early stage LCA"


With this method designers can (fairly) easy get a reading of your projects CO2 footprint where both construction and operation is taken into consideration.


There´s a Danish version, prepared to meet the danish regulations that will be implemented in 2023.

There´s an international version where vaules and settings needs to be adjusted to meet your local regulations, demands and EPD´s .

Feel free to download  the international version from this website:

The Danish version is part of our Localization, and can be downloaded from our website:


Please leave a comment if this could be usefull for studio.

ok,thank you. I understand. What exactly would we need to do to set it also for INT or GER version?

We would import the ökobaut (or do you maybe have it somehow directly linked?) and then adjust with Archicad building material setting possibilities?



Hi Tjasa.


I would like to add that; The amount of embodied carbon has to be added in the DesignLCA Material settings. However the Physical Material Properties (AC Properties) will be used by the Energy Evaluator (Eco Designer Star) - These calculations, made by Eco Designer Star, will be send to DesignLCA, in order to complete the LCA calculations. Thus you need to add both the Physical Properties in the AC Properties, and the Embodied Carbon value in DesignLCA Material settings.


It should also be mentioned that the DesginLCA engine will also use the Physical Property "Density" in order to convert Embodied carbon, if unit is set to kg. in DesingLCA. (becuase it will read the volume of the material in the model)

Thank you Thomas!

We have just released DesignLCA version 1.0 (out of beta), with new functionality to exclude objects from the LCA calculation or just calculate a percentage of the CO2 footprint of the object.

This looks really promising! 

Unfortunately I'm having problems with getting the Building Materials LCA settings to be saved after I fill in the EPD-data and click OK. When I open the settings again, all the values are back to zero. Are there any specific classifications or other settings in the Building Material panel that has to be filled in for them to be mapped correct?


I'm testing in AC26 build 4022 SWE full. 


I am also seeing a value input at the bottom, that moves around when I resize the panel window. Does that value do anything? see attached image.

Hello, how do I use the library with the co2 emitting materials? 

Hi . You need to "add" the Add-on..  Then run Energy Model Review via Ecodesinger Star, and export the result to Design LCA. Then open and and update DesignLCA in AC, and see the results 😉

In the International version, you need to fill out the data on the building materials, according to your local standards or epd´s for the Materials you will use in your project.

Remember to fill out the data regarding Heat/energy transimission, and Density in AC´s building Material Editor. Then The embodied CO2 value should be added in  DesignLCA->Building Materials LCA Settings. 🙂


The reason for this, is that Ecodesinger Star calculates the amount of energy it takes to Heat and cool the building acc. to the needs of the Zones. This is the energy simulation part. And it uses the Standard AC Parameters defined in the Building Materials. Then The amount of Embodied Carbon added to the project via, building Materials (and Components etc) is calculated by the CO2 amounts stated in DesignLCA->Building Materials LCA Settings.


It is stated in page 6-8 in the online Manual 😉



The final LCA result is a combination of both of the above mentioned calculations.

Hi, thanks for the app! Is it possible to add door or window types? For instance a metal interior door or metal/glass exterior window.



It is possible yes! The GWP from the windows and doors are stored in a set of properties. I have attached a short video on how to add or edit the windows and doors. Hope this is helpful 😊
