Realty Energy Pass

The energy certificate (Energieausweis) of a realty is returned as an energiepass element inside zustand_angaben. It is part of the realty detail response and of the realty list response when requested with showDetails=1.

The energiepass element is only present if a heating demand (HWB) or a total energy efficiency factor (fGEE) or a final energy demand (EEB) is set on the realty. There are valid combinations of these values (HWB+fGEE or HWB+EEB).

Elements

Element Description
epart Type of the certificate. Always BEDARF
gueltig_bis Date until the certificate is valid, formatted as Y-m-d
hwbwert Heating demand (Heizwärmebedarf / HWB) in kWh/m²a
hwbklasse Class of the heating demand
fgeewert Total energy efficiency factor (Gesamtenergieeffizienz-Faktor / fGEE)
fgeeklasse Class of the energy efficiency factor
eebwert New. Final energy demand (Endenergiebedarf / EEB) in kWh/m²a
eebklasse New. Class of the final energy demand, with an additional fossil attribute

Final energy demand classes (EEB)

List of all available final energy demand (Endenergiebedarf / EEB) classes of Justimmo. The class is returned as the bare letter in eebklasse; whether it is a fossil class is expressed by the fossil attribute. So the classes “B” and “B fossil” both return B and differ only in the value of fossil.

Name eebklasse fossil
A A 0
B B 0
B fossil B 1
C C 0
C fossil C 1
D D 0
D fossil D 1
E E 0
E fossil E 1
F F 0
F fossil F 1
G G 0
G fossil G 1

Heating demand and energy efficiency classes (HWB / fGEE)

List of all available classes for the heating demand (Heizwärmebedarf / HWB) and the total energy efficiency factor (Gesamtenergieeffizienz-Faktor / fGEE). The class is derived from the corresponding value, the columns below show the upper bound of each class. These classes are unrelated to the final energy demand classes above.

Class max. HWB (kWh/m²a) max. fGEE
A++ 10 0.55
A+ 15 0.70
A 25 0.85
B 50 1.00
C 100 1.75
D 150 2.50
E 200 3.25
F 250 4.00
G no limit no limit
