The ICM Database (Integrated Carbon Metrics Embodied Carbon Life Cycle Inventory Database) provides Australian-specific Carbon Footprint Intensities for around 650 construction and building materials, as well as built environment-related products and processes, based on a hybrid life cycle assessment methodology. Detailed analysis and reliable quantification of embodied greenhouse gas emissions of buildings, precincts and infrastructure are a vital part of designing a low carbon built environment and achieving emissions reductions. The ICM database can be used to calculate embodied greenhouse gas emissions of construction materials, building products and processes in the construction and/or operational phase of buildings, precincts, infrastructures and other applications in the built environment. Carbon Footprint Intensities were calculated using the Integrated Hybrid Life Cycle Assessment method, where the monetary input-output table is connected to the physical process matrix. Two main types of data are hybridised in this database- Process data from the Australian National Life Cycle Inventory Database are connected with Input-output data from an Australian national Supply-and-Use Table (SUT). The ICM Database was created by the Sustainability Assessment program at UNSW Sydney, and is an output of the Integrated Carbon Metrics project (number RP2007) supported by the CRC for Low Carbon Living (CRCLCL).
A rapid review on green-rated office buildings, and their operational energy use, found that the conclusions of six studies ranged from the certified buildings performing worse, similarly or much better than the non-certified buildings in terms of energy usage intensity. Two...Read more
Industry misconceptions around high cost and poor market interest in energy efficient homes continue to obstruct the mass adoption of low carbon housing. Josh’s House demonstrates that low carbon housing is accessible and cost effective. The Star Performers series showcases how...Read more
In response to feedback, high-income households can reduce their energy use to a larger degree than low-income households (17% vs 3% reduction). This and other insights were gained by two rapid reviews into research, both Australian and International, on digital services and...Read more
As global population and urbanization increase, so do the direct and indirect environmental impacts of construction around the world. Low-impact products, buildings, precincts and cities are needed to mitigate the effects of building construction and use. Analysis of embodied energy and greenhouse gas (GHG) emissions across these scales is becoming more important to support this direction.
As part of the Integrated Carbon Metrics project, which comprehensively quantifies embodied GHG emissions related to the built environment in Australia, this contribution evaluates construction material replacement scenarios at the economy-wide scale.
New research shows that 90 megatonnes of greenhouse gas emissions are emitted annually in constructing new buildings and infrastructure and maintaining the existing ones. Reducing this liability of “embodied” emissions will be much harder than building zero-carbon buildings. Here is why.
Cutter soil mix (CSM) walls are created by mixing soils with cement and bentonite slurry to produce a soil–cement mix with modest tensile and compressive strengths. CSM walls may be stabilised using internal steel beams. Presented here are the results of a CSM wall field trial and laboratory testing programme.
