RETROFIT AUSTRALIA • VOLUME 1 NUMBER 1 2012 • 37 Energy Efficiency | There are three credits within the Energy and Carbon category: • Ene-1: Energy and carbon monitoring and reduction • Ene-2: Energy and carbon reduction opportunities • Ene-3: Renewable energy Energy efficiency opportunities and infrastructure in the context of the EEO Act Energy efficiency is relevant to the ‘Ene-1’ and ‘Ene-2’ credits within the IS rating tool. Ene-1 rewards monitoring and minimising of energy use and GHG emissions across the infrastructure life cycle. Greater (Scope 1 and 2) GHG emission reductions (compared to a reference footprint) achieve higher scores for this credit. These reductions may come from all manner of activities. The intent of this category is to minimise energy use and GHG emissions at all stages of the infrastructure life cycle. In pursuing this intent, the following actions are encouraged, listed in hierarchical order: 1. reducing energy use and GHGs through design (i.e . designing out the need for activities that use energy or generate GHG emissions) 2. undertaking any necessary activities as efficiently as possible (i.e . maximising energy efficiency) 3. where feasible, using renewable energy to replace non-renewable sources 4. reducing GHG emissions using other low-emission sources (i.e . substituting natural gas for coal- fired electricity) 5. offsetting remaining GHG emissions to the extent practicable. Energy efficiency is at the top of the list and is typically amongst the ‘lowest-hanging fruit’, although this is not always recognised amongst the hustle and bustle of infrastructure project delivery. Ene-2 rewards identification and implementation of opportunities to reduce energy use and GHG emissions. This credit focuses on analysis of opportunities to reduce energy use and GHG emissions across the infrastructure life cycle. Broader scope of analysis and greater commitment to implementation achieve higher scores for this credit. No particular analysis method is specified, but the method does need to be documented and must comply with the new ISO 50001 International Standard for Energy Management. The credit also references the guidance available in standards on energy audits, the EEO Assessment Handbook and the EEO Energy Savings Measurement Guide as practical resources. To provide some assurance that opportunities will be taken up as actions during the construction and operation of the asset, they should be incorporated into management plans. The management plans should document: • the process used to identify opportunities to reduce energy use and GHG emissions • a list of all the opportunities identified (with explanations) • the process used to analyse and evaluate opportunities • commitments to implement particular opportunities during delivery and operation • explanations of why other identified opportunities were not taken up. AGIC commends and supports the recent development of the Options Paper ‘Extension of EEO Assessment to Greenfields and Major Expansions’ by the Department of Resources, Energy and Tourism. The proposal responds to a current policy shortfall in Australia for the adequate promotion of energy efficient design in our energy- intensive developments. There are many synergies between the AGIC IS rating scheme and the proposed EEO Assessment of Greenfields and Major Expansions. In its submission on the paper, AGIC identified: • the need to consider construction- phase energy use in new projects as well as the operations phase to ensure a ‘whole-of- life’ approach is adopted. It should be recognised that some infrastructure projects actually involve more direct energy consumption during construction than during operation (for example, a viaduct may consume large quantities of energy for construction, but only small quantities for operation and maintenance, even over a 30-year or longer life span) • the benefits of promoting consideration of energy use by infrastructure users during the operations phase – not just energy use directly associated with the infrastructure asset.
