With the recent changes to the National Construction Code and more changes due in 2022, energy compliance is becoming an ever-changing landscape. Commercial property space and energy efficient design is fast becoming mandatory for builders and developers seeking to gain compliance on commercial development projects.
The team at Frys Energywise is accredited to assess the National Construction Code (NCC) for new commercial and retail buildings (classes 2 to 9) including childcare centres, offices, shops, medical centres, and more.
The eight main sections in the NCC are:
Part J1 – Building Fabric
Part J2 – Glazing
Part J3 – Building Sealing
Part J4 – Air Movement
Part J5 – Air-conditioning and Ventilation Systems
Part J6 – Artificial Lighting and Power
Part J7 – Heated Water Supply and Swimming Pool and Spa Pool Plant and
Part J8 – Facilities for Energy Monitoring
We can assist in completing the most cost effective form of assessment – the DIY Assessment or the more flexible JV3 Assessment – to get the best outcome.
The DIY Assessment uses a facade calculator to determine glazing values required after the orientation, shading and frame material has been nominated. This assessment considers the wall, floor and ceiling material as separate items. These materials are then evaluated against the tables for compliance in the BCA for the specific type of building and climate zone. Often, this type of assessment identifies the need for improved glazing. Recent changes to the DIY assessment has seen a focus more on the reduction of Greenhouse Gas (GHG) emissions. Therefore, adding solar photovoltaic panels can assist in reducing GHG emissions of the building, assisting in meeting the required compliance.
Conducting a JV3 Assessment by an experienced and qualified energy efficiency consultant, uses a dedicated and approved software to evaluate the whole building – allowing certain over-performing areas to compensate for other areas that may not be performing as well, i.e. windows. In the majority of cases, the JV3 Assessment delivers a much better glazing result and the additional cost of undergoing this assessment is normally well below the cost of installing improved glazing.
At Frys Energywise, we offer Section J Report or Compliance Assessments, which typically covers new commercial buildings and residential buildings.
