Modification History

Release 2

This version first released with CPP Property Services Training Package Release 14.0.

Updated reference to reflect correction in Modification History from CPC Property Services 5.0 to CPP Property Services 9.0.

Release 1

This version first released with CPC Property Services Training Package Release 5.0.

Supersedes and equivalent to CPPHSA4019A Inform clients about thermal performance of residential buildings. Updated to meet the Standards for Training Packages.

Application

This unit specifies the skills and knowledge required to explain the factors that contribute to the thermal performance of residential buildings when providing advice to clients as part of a home sustainability or Nationwide House Energy Rating Scheme (NatHERS) assessment. It includes explaining the heat transfer process, factors that impact thermal comfort, how climatic conditions, building design and materials influence thermal performance, and the principles of passive design.

This unit is for individuals who work independently as home sustainability or NatHERS assessors who use specialised knowledge to assess and make recommendations for improving the thermal performance of residential buildings. It involves completing routine and non-routine tasks and dealing with predictable and sometimes unpredictable problems.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

Pre-requisite Unit

None.

Unit Sector

Home Sustainability.
