The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package. | |
Overview of assessment | This unit of competency could be assessed by performing a range of tasks in the workplace or a close simulation of the workplace environment, provided that simulated or project-based assessment techniques fully replicate construction workplace conditions, materials, activities, responsibilities and procedures. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | A person should demonstrate the ability to: develop an action plan to retrofit and improve the energy efficiency of either one existing residential building or one existing commercial building, providing evidence of the following: engaging in a team environment working with stakeholders across multiple disciplines, such as engaging or leading an integrated project design or delivery of a project research undertaken to identify appropriate products, materials and systems for use in the retro fit evaluation of risks involved in the retro fit and identification of appropriate solutions to avoid risks or hazards to occupants and others written action plan for the retro fit of the building which responds to identified client requirements and expectations, as well as research undertaken into energy efficiency opportunities and recommended systems, materials and products to be used in the retro fit with relevant costings and timelines locate, interpret and apply relevant information, standards and specifications to ensure the development of compliant action plans that meet client expectations and organisational policies and procedures comply with work health and safety (WHS) legislation, regulations and codes of practice applicable to workplace operations. |
Context of and specific resources for assessment | Assessment of this unit: must be in the context of the work environment may be conducted in an off-site context, provided it is realistic and sufficiently rigorous to cover all aspects of workplace performance, including task skills, task management skills, contingency management skills and job role environment skills must meet relevant compliance requirements. Resource implications for assessment include: an induction procedure realistic tasks or simulated tasks covering the mandatory task requirements relevant specifications and work instructions tools and equipment appropriate to applying safe work practices support materials appropriate to activity research resources, including industry-related systems information safety data sheets. |
Method of assessment | Assessment for this unit must verify the practical application of the required skills and knowledge, using one or more of the following methods: direct observation of tasks in real or simulated work conditions questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application review of relevant authenticated documentation from third parties, such as existing supervisors, team leaders or specialist training staff. |
Guidance information for assessment | This unit could be assessed on its own or in combination with other units relevant to the job function, such as: CPPHSA4001A Assess household energy use Reasonable adjustments for people with disabilities must be made to assessment processes where required. This could include access to modified equipment and other physical resources, and the provision of appropriate assessment support. Assessment processes and techniques should, as far as is practical, take into account the language, literacy and numeracy capacity of the candidate in relation to the competency being assessed. |
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. | |
Client requirements and expectations may | enhanced health and safety outcomes for occupants through improved air quality and selection of materials improved building durability increased return on investment through higher resale or higher rental income reduction in energy bills following retro fit. |
Energy assessment: | can include financial and non-financial benefits of retrofitting the building to improve energy efficiency can include recommendations that will improve the energy efficiency of the building identifies existing energy rating of a building using a variety of testing and assessment methods. |
