Every assessment reviewed by a person
NSW & QLD
Energy efficiency assessment and certification for residential and commercial projects.
Architect/Designer — needs energy compliance input during design
Builder — resolving an energy compliance question during construction
Developer — meeting energy requirements across a project
Property owner — renovating and needing an updated assessment
When you need this
Required for most new residential (BASIX, NSW) and commercial (Section J) building work, and for renovations that trigger reassessment.
What we assess
We assess your plans against BASIX or Section J requirements, review building fabric, glazing, and insulation performance, check proposed services such as hot water, heating, and cooling, and identify options to meet requirements without a major redesign.
