Energy Baseline shows two approaches side by side so you can trust the EMP figure.
Excel method (quote this for EMP)
Uses CSO-style assumed consumption per BER sub-band (A1–G), times homes in each band, scaled to the whole community. It mirrors SEAI’s master Excel template and is the figure to put in an Energy Master Plan submission.
BER method
Sums energy values from the actual BER certificates in your selection, then applies the same community scaler. Useful as a cross-check against unusual stock or data quirks.
