¨ 
¨ 
Standard framed PV modules are just a transition
¨ Traditional IEC 61215/61730 norms are not
BIPV gives architectural relevance to PV
sufficient: general construction norms apply
BIPV is an architectural component
Ø  Security norms
BIPV is an active building material
Ø  Safety glass norms
BIPV plays a double function
Ø  Mechanical resistance norms
BIPV is rational Ø  Fire resistance norms
BIPV substitutes traditional materials
¨ Cost of Si Cells : 2003 : 600 €/m2 - 2013 : 60 €/m2 Nearly-Zero Energy Building Directive
¨ Cost reductions open new opportunities for the
entire building envelope
