Historic Sydney Office Tower Turns its Paper Waste into Clean Energy!

by , 08/13/14



The turn-of-the-century Legion House is located in the heart of Sydney CBD and has operated as a women’s hostel for the last 60 years. Francis-Jones Morehen Thorp was commissioned to redevelop a larger area that includes the building, which has been converted into a zero carbon structure that received the 6-Star Green Star Office certification. Because of the building’s location, which receives almost no sun during the day, the architects decided to opt for biomass gasification technology in order to create renewable energy on site.

Legion House can use commercial paper waste generated from the adjacent office tower through shredding and compressing this waste to form paper briquettes, which can be used in the gasification plant. Surplus power created by its independent system is to be supplied to the 50-storey commercial office tower on the site.

While traditional gasification plants utilize standard wood chips or briquettes made from compressed waste sawdust, Legion House uses paper waste. According to the architects, it is the first time this type of technology used in a large scale commercial office. The building also features chilled beam technology and rainwater harvesting and recycling systems.
