CPP41119 Certificate IV in Home Energy Efficiency and Sustainability

Get Qualified as a NatHERS Assessor

Kickstart your career in a rapidly expanding sector or build on your current skills with the CPP41119 Certificate IV in Home Energy Efficiency and Sustainability. We’ll give you the knowledge you need to assess residential building plans and existing buildings for thermal performance and potential improvements, and to advise on thermal efficiency and sustainability in today’s houses.

Only Accredited NatHERS Assessors can issue the coloured Accredited Universal Certificate for NatHERS and stamp plans with the official NatHERS logo and with over 70% of new buildings being rated by accredited NatHERS assessors, a huge opportunity exists to earn extra income.

Home sustainability is a similarly growing field in Australia, as the legal sustainability requirements for residential buildings increase and individual householders seek to reduce their personal impact on the environment.

By becoming an accredited NatHERS thermal performance assessor and/or home sustainability assessor, you can join the small number of busy recognised professionals in these fields across Australia.

Becoming an Assessor

Becoming an accredited NatHERS thermal performance assessor

The CPP41119 Certificate IV in Home Energy Efficiency and Sustainability is designed to tick the boxes of assessors operating under the Nationwide House Energy Rating Scheme (NatHERS), which promotes residential building design that helps to reduce manual heating and cooling. This is generally achieved through effective passive building design and the use of residential building materials that help to reduce heating and cooling requirements.

Once you have completed the course, you’ll be able to apply for registration (accreditation) as an energy rater or assessor with Design Matters National and the Association of Building Sustainability Assessors (ABSA).

This course satisfies the competence requirements to conduct thermal performance ratings in all jurisdictions and to complete BASIX assessments for Development Applications for multi-storey unit developments in NSW.

Becoming a home sustainability assessor

The CPP41119 Certificate IV in Home Energy Efficiency and Sustainability is also designed to meet the needs of residential sustainability assessors, who provide advice to building owners on how to improve the sustainability of their homes. Home sustainability assessors not only investigate the thermal performance of a residential building, but also look at the overall energy and water efficiency of the household and may make recommendations about other areas such as waste generation and disposal.

Course Overview

The CPP41119 Certificate IV in Home Energy Efficiency and Sustainability is designed to meet the needs of thermal performance assessors operating under the Nationwide House Energy Rating Scheme (NatHERS), and home sustainability assessors.

During the course, you’ll study best practice theory with practical workplace application. Work at your own pace using our online library filled with study notes, videos and webinars for each unit of competence. Access articles and resources on demand and watch videos when it suits you.

You’ll learn how to assess household energy and water use, collect information to inform a NatHERS thermal performance assessment, recommend improvements to building design and select high performing building materials within a set budget. This course will also arm you with the skills you need to work with clients, and to manage both your own work performance and your safety and security in different work situations.

By the end of this course, you will have an understanding of the specialist skills and knowledge required to become effective as a NatHERS thermal performance assessor and home sustainability assessor.

Plus, learn how to use the latest software to complete thermal performance planning, modelling and costing tasks using FirstRate5.
