A design flexibile and cost-effective approach to meeting the energy efficiency requirements of Section J
Section J of the National Construction Code (NCC), outlines the minimum energy efficiency requirements for all building classes. Section J compliance can be achieved via two approaches:
Deemed-to-Satisfy (DTS) provisions or
JV3 Alternative Method Modelling
The DTS approach requires the building to meet the fixed, rigid requirements of the NCC, such as fixed insulation values or window performance.
The JV3 method uses building simulation to show equivalent performance to a reference building built to the DTS requirements. If the proposed design solution shows the same or better simulated performance than the reference building then it is deemed to be compliant. A JV3 assessment gives the client & design team greater design flexibility and the potential for cost-optimised energy efficiency specifications to meet the requirements of Section J.
"We engaged Urban Digestor to write a Section JV3 report to assist with finding the most appropriate, compliant and cost effective glazing specification for a recent retail project. The team were incredibly communicative, pro-active and helpful. The concise report was delivered quickly and enabled us to find the most appropriate specification for the glazing within the holistic context of the project’s energy assessment. We wouldn’t hesitate to work with Urban Digestor again."
