- Public Sector Building demand isn't included as it currently isn't possible to locate all buildings within Small Areas as the data is at postcode level

- Buildings with floor areas much larger than expected for the use type were removed. See [benchmarks.csv]({{ benchmarks_csv }}) for benchmark properties.

- 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`.
