Generic Building Types

The climatic zones are defined on the basis of the Heating Degree Days in accordance to the national regulation for the Energy Performance of the Building Sector (KENAK):

Zone A (601–1100 HDD)

Zone B (1101–1600 HDD)

Zone C (1601–2200 HDD)

Zone D (2201–2620 HDD)

NOTE: Officially reported floor areas (tabulated under “National”) refer to total (gross) floor areas measured using external dimensions. These include non-heated areas (basements, corridors, stairwells etc.). In order to convert this information to the TABULA reference areas it was necessary to make an assumption of the average percentage of the total area that corresponds to the heated floor area in SFH and MFH buildings. In collaboration with the NAG the percentages 70% and 80% were adopted for SFH and MFH buildings respectively.
