Energy ratings are a familiar measure of the energy efficiency of appliances in Australian homes. Using an energy rating is also a way to demonstrate that new homes achieve a level of energy efficiency under Volume Two of the National Construction Code (NCC).
Our NCC continuing professional development (CPD) course on housing energy efficiency provides introductory information about NCC energy efficiency requirements for Class 1 and some Class 10a buildings. It introduces the Deemed-to-Satisfy (DTS) pathways in addition to NCC Verification Methods for developing a compliant Performance Solution for energy efficiency.
The relevant NCC provisions aim to reduce greenhouse gas emissions through appropriate passive energy efficiency measures built into the dwelling. Therefore, an understanding of some basic building science concerning heat transfer is useful for architects, building designers and others.
Although an energy rating approach using NatHERS is the more common method of demonstrating compliance with the NCC, there are other approaches also. The elemental DTS approach uses prescriptive minimum requirements, and the reference building Verification Method specifies development of a Performance Solution to compare a proposed design to a ‘reference building’.
Delivering either a DTS Solution or a Performance Solution also requires an understanding of factors including the use of thermal breaks, the R-value of insulation, the performance of glazing and the role of orientation and building sealing.
The course is delivered online in a multi-media format. It is informative, engaging and provides practical insights and information that participants can apply in their practice. It has also been recognised by the Australian Institute of Architects for the purposes of formal CPD points as part of the Refuel program.
For any participant, it also provides a credible recognition of understanding NCC energy efficiency provisions that will build confidence with clients.
