10 in 10

Transurban’s energy usage is mainly driven by needs for tunnel ventilation and road lighting (particularly in tunnels). Our operational energy profile has been relatively consistent over time due to the 24/7 operation of our roads. To make meaningful reductions in energy usage, we must therefore focus on energy-efficiency initiatives.

Transurban has committed to a ‘10 in 10’ energy target of reducing total energy usage by 10 per cent in 10 years, from a 2013 baseline.

As part of this commitment, Transurban is identifying a range of initiatives and pilot projects to reduce energy usage on our assets. When projects are successful, we have the ability to share these improvements across our road and tunnel assets and multiply the benefits.

National energy portfolio

In FY15, Transurban initiated a national procurement exercise to provide for efficiency in the management of energy and reduce costs. This included the review and consolidation of energy supply contracts across our assets to target greater value and consistency in energy supply arrangements for our assets.

We also engaged an energy services firm to act as a National Energy Portfolio Manager and provide energy procurement, monitoring and reporting services for our Australian assets. This agreement will provide us with nationally consistent energy usage and expense data, giving us greater ability to monitor and reduce energy.

With improved access to energy monitoring, we will also develop a more accurate, targeted list of initiatives to achieve our ‘10 in 10’ target.

Green buildings

While energy use from our offices represents only a minor proportion of our total consumption in comparison to road assets, we are committed to reducing this amount wherever we can.

In May 2014, our Melbourne headquarters moved to 727 Collins Street, where more than 450 of our employees are based. At this new site, we have committed to achieving a 5-star NABERS (National Australian Built Environment Rating System) energy tenancy rating. NABERS is a national rating system in Australia that measures the environmental performance of Australian buildings, tenancies and homes.

Now that we have occupied our new Melbourne office for a full year, Transurban is able to complete a NABERS certification assessment. Based on an initial self-assessment our energy usage appears to meet the requirements for a 5-star NABERS energy tenancy rating, and we are currently in the process of having this verified by an independent certification audit.

In the US, our Express Lanes Operations Centre received the LEED (Leadership in Energy Environmental Design) Certification for New Construction from the U.S. Green Building Council in October 2014. LEED is a leading international green building certification program that recognises energy and resource efficiency in many aspects of construction and building occupancy.

The LEED certification recognises the planning that went into designing the Operations Centre to run efficiently and minimise resource use.
