This European Standard specifies the:
- required inputs;
- calculation method;
- required and resulting outputs,
for heat generation systems, thermal solar systems (for space heating, domestic hot water production and the combination of both) and for photovoltaic systems applied in buildings.
Within this standard, 6 methods are specified each method has its own range of applicability.
- Method 1,
is applicable for solar domestic hot water systems characterized by the EN 12976 series (factory made) or EN 12977-2 (custom built).
The main output of the method is the solar heat and back up heat contribution to the requested heat use.
- Method 2,
is applicable for systems for domestic hot water and / or space heating with components characterized by EN ISO 9806 and EN 12977-3 or EN 12977-4 with a monthly calculation time step.
The main output of the method is the solar heat and back up heat contribution to the requested heat use.
- Method 3,
is applicable for systems for domestic hot water and / or space heating with components characterized by EN ISO 9806 with an hourly calculation time step.
The main output of the method is collector loop heat supplied to the heat storage.
- Method 4,
is applicable for photovoltaic systems with components characterized by standards and with an annual calculation time step.
The output of the method is the produced electricity.
- Method 5,
is applicable for photovoltaic systems with components characterized by standards and with a monthly calculation time step.
The output of the method is the produced electricity.
- Method 6,
is applicable for photovoltaic systems with components characterized by standards and with a calculation time step.
The output of the method is the produced electricity.
These three last calculation methods do not take into account:
- electrical storage;
- PV/thermal photovoltaic systems.
Primary energy savings and CO2 savings, which can be achieved by photovoltaic systems compared to other systems, are calculated according to EN ISO 52000 1.
NOTE 1 Standards linked to the methods are listed in Annex E.
Table 1 shows the relative position of this standard within the set of EPB standards in the context of the modular structure as set out in EN ISO 52000 1.
NOTE 2 In CEN ISO/TR 52000 2 the same table can be found, with, for each module, the numbers of the relevant EPB standards and accompanying technical reports that are published or in preparation.
NOTE 3 The modules represent EPB standards, although one EPB standard may cover more than one module and one module may be covered by more than one EPB standard, for instance a simplified and a
detailed method respectively. See also Clause 2 and Tables A.1 and B.1.
