Continuous insulation layer
Removal of humidity
Reduction of thermal transmittance
Acoustic insulation
Available space for hidden drainage systems, pipes or wiring
Easy installation - Simple maintenance works
Retrofitting: works do not disturb building´s users
Aesthetic value

PHOTOVOLTAIC GLAZING AREAS

SLIDE 28

PV glazing areas

conventional glass a-si PV glass

Natural illumination
Absorption of the infrared and UV-radiation
Reduction of heat gains in warm climate conditions
Different see-through degrees
Visual relation between inner and outer space of buildings
Free energy production

CONCLUSIONS

SLIDE 32

BIPV solutions replace conventional construction materials
Active and passive properties contribute to Passive House

certifications

EnerPhit step by step projects should consider the implementation of

BIPV systems as a decision to be evaluated in the first steps of the plan
