Elements and Performance Criteria

1. Acquire required data
   • Identify system to be analysed
   • Define appropriate boundaries for this system
   • Identify relevant data which is available for the system and its subsystems
   • Identify required data which is not currently available
   • Negotiate with relevant stakeholders to obtain data which is not currently available
   • Acquire necessary and appropriate data
2. Calculate resource efficiency/loss
   • Undertake mass/energy balance over system
   • Identify subsystems making greatest contributions to loss by mass/energy balances over selected subsystems
   • Calculate sustainability impact of identified losses
   • Calculate mass/energy efficiencies of system and analysed sub-systems
3. Prepare recommendations
   • Investigate sub-systems responsible for significant loss
   • Determine currently available responses
   • Determine required longer term responses
   • Draft recommended responses in appropriate form
4. Communicate with relevant stakeholders
   • Identify relevant stakeholders
   • Determine stakeholder information needs and wants
   • Analyse data which may be appropriate to communicate with stakeholders
   • Prepare and disseminate information to stakeholders, as appropriate
   • Negotiate solutions with stakeholders, as required
5. Communicate required responses as appropriate
   • Identify what communications are required and to whom
   • Prepare appropriate reports and recommendations
   • Pitch reports and recommendations as appropriate
   • Brief appropriate persons as required by determined responses
   • Finalise appropriate recording

Required Skills

Required skills

Required skills include interpreting specifications operating procedures manuals regulations and other complex documents consulting and negotiating with internal and external stakeholders analysing and problem solving including determination of root cause data acquisition interpreting and manipulating data including the solving of simultaneous equations the use of tie elements and the conversion of one form of energy into another drafting formal reports

Required knowledge

Required knowledge includes process and changes which occur at each step in selected value chain principles of sustainability root cause analysis relevant legislation regulation and protocols government incentives and other initiatives first law of thermodynamics defining boundaries for systems subject to massenergy balancing required data sources of data from process and use of data proxies where necessary mass balancing techniques energy balancing techniques including the use of tables of thermodynamic properties steam tables and the use of specific heat capacity and specific latent heat combined massenergy balancing techniques including the use of heats or reactiondissolution methods of reducing resource losses for process and equipment

Evidence Required

Overview of assessment	A person who demonstrates competency in this unit must be able to analyse processes or part or all of a value chain using mass andor energy balancing as appropriate
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Assessors must be satisfied that the candidate can competently and consistently apply the skills covered in this unit of competency in new and different situations and contexts Critical aspects of assessment and evidence include undertaking a mass and an energy balance which may be on different systems or a combined massenergy balance identifying appropriate responses communicating the above as appropriate
Context of and specific resources for assessment	This unit of competency is to be assessed in the workplace or a simulated workplace environment Assessment should emphasise a workplace context and procedures found in the candidates workplace This unit of competency may be assessed with other relevant units addressing sustainability at the enterprise level or other units requiring the exercise of the skills and knowledge covered by this unit The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team
Method of assessment	In all cases practical assessment should be supported by questions to assess underpinning knowledge and those aspects of competency which are difficult to assess directly Where applicable reasonable adjustment must be made to work environments and training situations to accommodate ethnicity age gender demographics and disability The language literacy and numeracy demands of assessment should not be greater than those required to undertake the unit of competency in a worklike environment

Range Statement

Sustainability	Sustainability incorporates the three aspects of: survival of the ecology/physical environment (to manage the impact of the business to ensure the survival of the physical environment) economic viability (efficiency, cost and waste reduction and competitiveness to support survival of the business) social sustainability (to manage the impact of the business to ensure its continued survival within the community and the survival of the community)
System	A system is that process, or part of a process, which has been selected for analysis. It includes all the steps in the process which fall within the defined boundary. These steps have been referred to as ‘sub-systems above. The system may be any part of the value chain or the entire value chain
Sub-system	A sub-system is part of the system which may be chosen for separate analysis or study
Portion of the value chain	Value chain is the sequence of activities that a firm undertakes to create value/product (good or service). Portion of the value chain includes: sections internal or external to the organisation
Mass/energy balancing	Mass balancing is an analysis technique which allows for the calculation of mass flows and consumption through a process and losses of mass from the system/product Energy balancing is an analysis technique which allows for the calculation of energy flows and consumption through a process and the losses of energy from the system/product Mass and energy balancing may be undertaken as separate activities or in some circumstances as a combined mass/energy balance
Appropriate response	Appropriate response includes: application of the hierarchy of hazard control to sustainability hazards when the impact cannot be prevented application of mitigation and amelioration techniques, such as: capture and storage (e.g. scrubbing) and similar ‘end of pipe’ solutions dilution/dispersion and similar techniques which reduce concentration but not amount other approaches which meet the sustainability requirements
