South West of Paris (15e) – Headquarter of the French Army, Airforce & Navy

A projet under the consortium « Opale Defense » led by Bouygues Constructions

A BIPV project implemented by ISSOL

PHOTOVOLTAICS MEETS THE FAMOUS ZINC ROOFS OF PARIS

Green architecture following the strictest standards – © HQE & BREEAM Certification

Bioclimatic design with assisted natural air ventilation Self-sufficient 10 months per year 80% of energy needs will be produced on site using renewables A 820 kWp (7000 m2) BIPV installation ”zinc colour” The largest integrated solar roof of Paris Above 820 MWh per year of locally produced electricity

A BIPV Challenge

DESIGN

No Photovoltaic/Technology appearance Homogeneous rendering – dark zinc – Paris roofs Triangular shaped roofs 1,500 different module shapes to match the roof geometry PV modules acting as building materials (élements constructifs actifs) Substitution of steel gratings (caillebotis)

A BIPV Challenge

TECHNICAL

Custom-made cells colour – special development No visible ribbons or wires Fire Class 0 (BS1d0) – no combustibility – for very risky areas Anti glaring – Candela < 10 000 – for safe airship landing 12 mm laminated safety glass for accidental shock resistance – glass/glass No visible mounting system PV glasses raised on steel framework and fixed on secondary aluminium

PV Technology

Mono crystalline PV technology 187 000 PV 6’ cells – 4,46 Wp Custom-made cells colour – special development No visible ribbons or wires Glass glass

187 000 PV cells – 4,46 Wp

Case study conclusions

It is possible to give an architectural relevance to the technology Standard solar modules are just a transition Traditional IEC 61215/61730 norms become irrelevant : general

construction norms apply Security norms Safety glass norms Mechanical resistance norms Fire resistance norms

PV is an architectural component PV is an active building material PV plays a double function PV is rational PV substitutes traditional materials BIPV Cost = Cost of construction material + cost of PV The cost reduction of the technology opens new doors/new opporutinity to

tackle the entire building envelope 2006 : 490 € / m2 2013 : 72 € / m2 * Nearly-Zero Energy Building Directive
