History
Open skylights were used in Ancient Roman architecture, such as the oculus of the Pantheon. Glazed "closed" skylights have been in use since the Industrial Revolution, when advances in glass manufacturing made them practical. Since the mid-20th century, advancements in durable translucent plastic material such as ETFE have brought them to many more uses and contexts. Energy conservation has brought new motivation for design innovations and efficiency ratings.
