The major amendment of the EN 15804, EN 15804+A2 will become mandatory in July 2022 for all the tools following the standard.
A2 Data availability in Building LCA
In the meantime, some Building LCA tools already allow the use of A2 data. However, A2 data is not usable in full LCA tools as it has different impact assessment categories overall compared to A1. To learn more about the differences between EN 15804+A1 and EN 15804+A2, click here.
- Klimatdeklaration av byggnader (SE)
- The Low carbon assessment tool (FI)
We are starting to also include A2 EPDs to GLA/RICS tools. They should be available in Q3.
In those tools, the impact category taken into account to calculate GWP is Global Warming Potential - Fossil.
PS: For some new data points in those cited tools, you can find both values for Global warming potential (EN 15804+A1 and EN 15804+A2), but rest assured that the value used for calculations is the one compliant with EN 15804+A2.
A2 Data availability in Product LCA
On the Product LCA side, in our Pre-verified EPD Generator & EPD Hub tools, all results categories can be calculated automatically in line with both EN 15804+A2 as well as EN 15804+A1 (and optional formats such as TRACI 2.1, INIES or NMD).
Data in EN15804+A2 format can already be used in Product LCA assessments as well. To learn more about how to use A1 & A2 data in product LCA, please click here.
