FEASIBILITY STUDY OF AMORPHOUS SILICON SKYLIGHTS IN BISCAY
Reduction in HVAC energy demands
Internal Rate of Return
- Total Area - 270 M2
- Electricity generated in 35 years - 475.839 kWh
- Total lighting points operating 4 hours per day in 35 years - 933 lighting points
- Avoided CO2 emmisions in 35 years - 319 CO2
- Barrels of oil saved in 35 years - 280 barrels
The project, with over 200 m2 of photovoltaic glass integrated in the curtain wall and skylight, is considered to be one of the most outstanding photovoltaic integration solutions in the whole of Europe.
The low-emissivity (or low-e) glass used is made of amorphous silicon and features a semi-transparency degree of 20% (L vision). This type of glass enables the passage of daylight into the interior while it filters out as much as 99% of the ultraviolet radiation and 95% of infrared light, thus preventing harm to the interior furniture, to persons or to plants, and the greenhouse effect which is so common in glass-covered buildings.
The skylight and the curtain wall total an installed power capacity of 21 kWp and generate approximately 16,500 kWh per year, while preventing the release of 11 tons of CO2 into the atmosphere.
Located in the Biscayan town of Larrabetzu, this restaurant with three Michelin stars and headed by Eneko Atxa, has won, in only two years, the 19th place in the ranking of “The World’s 50 Best Restaurants”.
