Sustainability Learning Centre
Greening Australia, the Tasmanian Department of Education, CSIRO Education, Independent Schools Association of Tasmania and Catholic Education Office partnered on this fantastic project to deliver innovative and inspiring sustainability educational programs for children of all ages in Hobart. An eTool LCA was conducted in May 2012 when the Sustainability Learning Centre was already under construction and the centre opened in early November 2012.

Extended design life due to custom architectural high quality design.
Use of low carbon materials. ClinkaBloks for example, reduced the embodied carbon by approximately 11tCO2e compared to standard 500 x 300mm concrete footings. Other materials used included recycled timber and recycled metal cladding, representing 4t CO2e and 15t CO2e carbon savings over the design life respectively. Light frame timber construction with low embodied carbon.
Operational Energy and Thermal Performance
Results achieved an eTool gold medal rating and represent a fantastic 111% saving when compared to a benchmark in the same climate zone (with solar PV and hot water taken into account). Typically HVAC is the largest energy user in commercial buildings. The energy demand of the Sustainability Learning Centre has been reduced through the use of passive heating and cooling systems including:
- Cooling in summer provided by stored cooled water circulated through the under floor radiant piping. The water itself is cooled at night by reticulation over the roof.
- Heating through passive solar walls incorporating thermostat operated fans distributing warm air from the wall cavity into the building when appropriate.
- Heating through passive trombe walls to store heat in the masonry behind glass.
