The Azurmendi Restaurant has not only obtained the LEED Gold certification but was also declared the Most Sustainable Restaurant in the World in 2014.
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
