Our services in detail

Energy Rating Reports:

All new houses, extensions and alterations need to comply with the Energy Efficiency provisions of the National Construction Code (NCC). Our energy rating reports evaluates how well your project fulfills those provisions by calculating the heat and cooling loads per year. All states and territories have slightly different provisions and/or applicable concessions due to local jurisdictions and climate zones.

Once provided with your project’s documentation incl. architectural plans and project specification, our energy rating reports will evaluate how your new home will perform against the provisions of the NCC. 

Section J Reports (or Part J Report - commercial):

A section J report evaluates a building against the energy efficiency requirements for Class 3, 5, 7, 8 and 9 buildings (commercial) of Volume One of the National Construction Code (NCC) and is required for commercial projects.

The Deemed-to-Satisfy (DtS) provisions of Section J of the NCC Vol. 1 establish the minimum requirements for the building envelope such as roof and wall insulation, glazing systems, shading and climate zone.

Energy Efficiency Consultation:

If your initial design does not meet the minimum requirements within your area, we are able to assess the proposed glazing system, insulation, wall systems, shading devices and orientation of your building and propose the most cost-effective solution to get your project underway.
