Fernando Herrera shared with us some very interesting photos of the California Academy of Science (previously posted with the official photos). First, a series of pictures from the opening day on which you can see the building with people on it, and get a better idea on the scale and how it works. He even caught Renzo Piano admiring his own work!
Also, he sent us a series of pictures of the green roof during construction, on which you can see more details such as the irrigation system and the skylights.
Enjoy the gallery! I also recommend checking out Fernando´s Flickr page, he has photographed an interesting selection of contemporary buildings in the US and Europe.
