1 Bligh Street

Project Description
Sydney, NSW, Australia

At the time of construction, 1 Bligh Street set a new environmental performance benchmark for the development of tall buildings.  This project has the distinction of being the first double-skin ventilated facade office building in Australia.  One key to the performance of this building is Embedia's Solarai control system.  By optimally positioning the horizontal (venetian) blinds, located within the facade, solar heat gain is effectively minimized greatly reducing energy used by mechanical cooling systems.  Optimal positioning allows exterior views to be maintained while uncomfortable glare is eliminated and natural light is harvested.  Thanks to the unique dynamic facade, 45 per cent of the interior space achieved high daylight levels significantly reducing reliance on artificial lighting.  A multi-year study performed by the environmental and sustainable design consulting firm Cundall, estimated a 42% reduction in carbon dioxide emissions and annual energy saving of over $2 million compared to similarly sized conventional office towers.
