Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Instructions to Assessors

Evidence Guide

Overview of assessment

A person who demonstrates competency in this unit must be able to conduct an energy audit, including calculation of theoretical and actual use of energy and preparation of recommendations for energy use reduction.

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:

defining appropriate boundaries for the sustainability energy audit

conducting energy balance analyses for a site or value chain

identifying high energy use/waste units/areas

undertaking benefit/cost ratio analyses

ensuring improvement strategies proposed reflect stakeholder needs and regulatory environment.

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 candidate’s 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 work-like environment.

Guidance information for assessment

Required Skills and Knowledge

Required knowledge includes:

nature of energy wastage:

efficiency

friction/fouling/scaling

temperature/pressure range of operation

energy balancing techniques for process and process steps (sometimes known as heat balancing)

methods of measuring actual process amount/flows

waste reduction/energy efficiency strategies and methods along with costs, effectiveness and alternative strategies (e.g. efficient lighting, efficient window glass and efficient motors)

cost-benefit analysis

relevant legislation, regulation and protocols

AS/NZS ISO 14000 Environmental Management Standards

Required skills include:

mapping processes and energy flows

interpreting schematics and drawings

calculating, manipulating and interpreting numerical data, including establishing series, means, correlations and rates of change

ranking energy consumption and waste based on energy balancing

consulting with technical and operative staff on possible non-obvious energy wastes

consulting and negotiating with stakeholders on implementation process for sustainability improvement

preparing recommendations

Range Statement

Energy/energy type

Energy/energy type includes:

operational heating and cooling

motive energy

lighting

waste energy

Theoretical use of energy

The amount of energy (work) required to move a mass or heat matter is a basic physics calculation. This is the theoretical use of energy. Anything used above this is waste (although in physics it may be referred to as inefficiency)

Energy intensity

Energy intensity includes:

required temperature, power and pressure, as relevant
