Popular during the 19th century, the sawtooth roof has glass panels that face north, allowing for sunlight to enter a building without allowing in excess heat. Before electric lights were used, the sawtooth roof was the design of choice for factories and industrial buildings. First designed by British architect, William Fairbairn in 1827, the sawtooth roof became the standard throughout the industrial revolution.
The sawtooth roof fell out of favor for many decades as artificial lighting became the norm. In the late 20th and early 21st century however, this design has found renewed popularity. Energy efficiency and conservation have become a concern for modern day architects and newer buildings are being built to maximize the amount of natural light they can bring in. Sawtooth roofs have been proven to reduce energy costs so perhaps this historic icon of the industrial revolution will have a renewed legacy as an energy saving design.
