Verification Using a Reference Building (VURB)
Residential | Single Storey
This dwelling achieved a 4.5 Star Rating using the NatHERS assessment method. The project required the following adjustments to achieve a minimum 6 star compliance:
Insulate all external cavity walls, excluding Bed 2, Bed 3, Bath & WC (approx. 73m2)
When Structerre assessed this dwelling through the VURB method the following heating and cooling energy loads applied:
As the proposed house had heating and cooling energy loads which were equal to or less than the reference building, the proposed building was deemed compliant through V126.96.36.199 NCC 2013.
The proposed building was compliant based on the builder’s standard specification:
No cavity insulation or upgraded glazing was required for compliance.
This assessment method has been carried out in accordance with the V188.8.131.52 (a), (b), (c), (d) & (e) requirements by a Structerre qualified person using NatHERS accredited software.
Even though this project is not a 6 star energy efficient dwelling, it will still meet BCA V184.108.40.206 energy compliance.
The reduced construction costs are based on 73m2 x $15/m2 cavity insulation.
This equates to a potential cost saving of $1,095
