In the heart of the Sydney Central Business District (CBD) is the heritage-listed Legion House. A 5-story building of aesthetic and social significance due to its fine façade detailing and early association with the YWCA. Highly praised in Sydney for adapting to changing values of the CBD, including bold sustainability targets.
Overshadowed by skyscrapers, the comparatively small building has limited sunlight and wind access to generate renewable energy. To achieve the goal of being grid-independent, the team looked beyond PV cells and wind turbines and turned to gasification of sustainable fuel sources such as compressed recycled paper pellets and recycled woodchips.
Integral Group met the challenge of incorporating essential services in a heritage building while ensuring the Building Code of Australia (BCA) and Green Building Council of Australia (GBCA) requirements were met without compromising floor area and minimal impact on the ceiling. By locating most equipment on the roof of an adjacent non-heritage building, Integral was able to overcome the challenges of heritage building requirements.
Legion House is one of Sydney’s most sustainable commercial buildings. By producing all its power on-site, Legion House has achieved carbon neutrality, six-star Greenstar, and six-star NABERS ratings.
Integral Group provided mechanical, electrical, plumbing, fire projection, and technology design services as well as sustainability consulting for this project.
