BIPV TECHNOLOGIES

crystalline amorphous sillicon

A-si technology Best results in terms of kWh/kWp under diffuse irradiation conditions • • Absorption of infrared and UV-radiation • Best aesthetic solutions when combining with other cladding materials. • Different see-through degrees

PHOTOVOLTAIC VENTILATED FAÇADES

PV ventilated façade system 1 3 4 2 1. Wall or support 5 2. Thermal insulation 3. Air chamber 4. Substructure 5. PV Cladding

PV ventilated façade system 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 • + ENERGY PRODUCTION ON-SITE

PHOTOVOLTAIC GLAZING AREAS

PV glazing areas • 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 conventional glass a-si PV glass

CONCLUSIONS

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
