LCA for Infrastructure projects

After completing the LCAs for Brookfield Multiplex on the New Perth Stadium, for LendLease on the Waterbank – Infrastructure and Public Domain Area (IPD), and currently working on the NorthLink WA Southern Section with John Holland, eTool is excited to share with you how LCA can be used for Infrastructure project.

On this video recorded during our last webinar, LCD Engineer and Business Development Manager Henrique Mendonca shows why Life Cycle Design adds value to an infrastructure design process and how it can be done using eToolLCD software. It also provides an overview of potential IS credits (Infrastructure Sustainability) using Life Cycle Assessment by integrating materials, energy, water, waste, management and innovation in a single LCA model.

Design Civil Structures with eTool LCA

When we created eTool LCA, our aim was to reduce the global carbon footprint through the built form.
Initially we thought about buildings; residential, commercial and community based structures that would benefit from using a design life tool from conception to build to use. But this only gives us half the picture.

With eTool LCA we can look at all type of built forms including civil structures such as roads, bridges and dams. These types of vital infrastructure use energy through materials, transport, assembly and recurring maintenance just the same as traditional buildings, so it’s important that we account for them as well.

Watch our short video showing you how to build a road…

Using eTool LCA’s custom template feature, you can easily input the exact specifications of any structure, in the case of a road, we included the width, length and a combination of materials.
Once you’ve created an example template, you can add as many as you like and compare the environmental and cost implications across a number of variables to help with the decision process.

This LCA was based on an average 1km asphalt road with the following building specifications –

Floor Area: 1000m2
Floor Width: 500mm

“Shout It Out” Abstract

“Zero carbon building development is easy… with the right planning”

The built form is responsible for approximately 30% to 50% of Australia’s total carbon footprint.

Globally and now in Australia there are many examples of buildings that produce more energy than they consume and are theoretically “zero emission” buildings. These range from everyday mums and dads with standard 4×2 houses through to high rise commercial buildings. We now have the technology to be energy efficient and produce renewable energy at a cost effective rate to offset the buildings “operational energy”.

The largest component of a buildings carbon footprint is fast becoming “embodied energy” – the energy used to manufacture the materials, transport, assemble and then maintain them. The best way to reduce this embodied energy impact is through intelligent planning.

Plan for the future – the average Australian residential building is lucky to get much past its 50th birthday. The single biggest reason for a building to be knocked down in Australia is for redevelopment.

Plan for functionality – in the past 20 years our houses have grown in size by 40% while occupancy has dropped by 10%.

Intelligent planning ensures buildings last longer while increasing their functionality. The great news is once you are able to quantify these impacts (which eTool LCA can) it’s pretty easy to get the planning right.
