About us
Who We Are
We are Certified (HERA) Thermal Assessors for more than 10 years now and we undertake Energy Assessments for residential buildings – BASIX certificates that are mandatory in NSW (includes NatHERS thermal assessment only), NatHERS and Whole of Home (WOH) assessments for all other states – plus Section J reports (DTS & JV3) for commercial buildings.
Alterations and Additions
Alterations and Additions In NSW, extensions and/or alterations to existing homes that have a construction cost in excess of $50,000 and/or involve the installation of a pool and/or spa with a total volume greater than 40,000 litre are required to have BASIX certification.
The BASIX assessment tool has a section specifically designed for alterations and additions to existing homes. This section differs slightly from the single dwelling and multi-dwelling sections of the tool in that there are no set reductions for energy or water.
Instead the tool aims to reduce potential water consumption and emissions by encouraging efficiency improvements.
If you are building a new dwelling and including a swimming pool of any size it will need to comply with BASIX. If you are lodging plans for your pool as an alteration and addition you will need to comply with BASIX only if the volume of the pool is more than 40,000 litres. The BASIX requirements relating to the installation of a pool will depend on pool size, heating type and the water target zone.
