13. Objectives
• Explore technical and economical aspects of Building
Integrated Photovoltaics (BIPV)
Results after one year
• Façade produced 4,1 MWh electricity
• Overall total installation cost of BIPV only about 10% higher
than for traditional façade material
• Using thin-film solar cells would lower the cost further,
making BIPV equivalent in cost to passive façade
• Temperature and humidity did not pose problems
• Production was slightly lower than forecast, possibly due to
shading effects.
