Definition of BIPV
As quoted from EN 50583 standard:
“ Photovoltaic modules are considered to be building-integrated if the PV modules form a construction product providing a function2 as defined in the European Construction Product Regulation CPR 305/2011. Thus, the BIPV module is a prerequisite for the integrity of the building’s functionality. If the integrated PV module is dismounted (in the case of structurally bonded modules, dismounting includes the adjacent construction product), the PV module would have to be replaced by an appropriate construction product.
The building’s functions in the context of BIPV are one or more of the following:
– mechanical rigidity or structural integrity
– primary weather impact protection: rain, snow, wind, hail
– energy economy, such as shading, daylighting, thermal insulation
– fire protection
– noise protection
– separation between indoor and outdoor environments
– security, shelter or safety
Inherent electro-technical properties of PV such as antenna function, power generation and
electromagnetic shielding etc. alone do not qualify PV modules to be building-integrated.”
Definition of Building Attached Photovoltaic (BAPV)
As quoted from EN 50583 standard:
“Photovoltaic modules are considered to be building-attached, if the PV modules are mounted on a
building envelope and do not fulfil the above criteria for building integration.
(Negation: The integrity of the building functionality is independent of the existence of a building attached photovoltaic module.)

Building Integration
For the future buildings that are coming out, they are to meet the new
building standards which are that all new buildings have to meet a nearly
zero energy standard.
The few expect that can be are under Building Integration can be classified under these mounting categories
