- SEAI's DEAP model is representative of actual heat demands. In reality, DEAP tends to overestimate demands in older buildings it and underestimate it in newer.

- Unknown buildings are well represented by archetypes. These archetypes were created by filling unknown buildings iteratively with a sample of nearby, known buildings with a sample size of greater than 30. So if there is enough buildings of the same `Small Area` and `Period Built` this average is used, otherwise `Electoral District`, then `Postcode`, and finally `Period Built`.
