PV energy input into LCA

In the energy consumption tab on OneClick what is the figure I put if there is PV? I have a building that will use 421116 kWh. It will also generate 284800 kWh of electricity from PV. Therefore is the figure for energy consumption I input would this be 421116 - 284800 ? so 136,316? OR do I just input them on 2 different rows one for energy consumption and one for renewable energy generation?

Hi Josef,

First of all, apologies for the delayed reply. During the summer most of us are enjoying our holidays and unfortunately the forum replies are somewhat delayed.

If your asset consumes PV energy, this quantity is subtracted from the annual operational consumption. As this does not generate emissions, you leave it out completely (and track in the comment field the reason for lowering the original quantity). You could enter a row for the PV electricity, however you should then ensure you take a resource that has no emissions allocated to it.

Hope this helps,

Steven
