JV3 assessment is the alternative assessment method for non-residential buildings. JV3 assessment uses a reference building for comparing the overall assumed energy consumption of new buildings with respect to their climate and location.
There’re plenty of reasons why this flexible assessment method should be part of your new construction design. In the globe, there are no identical buildings with the exact same energy consumption.
A building with an identical layout, design and construction materials can have a different energy efficiency than its twin located many kilometres away. Due to its location and specific climatic conditions, the annual energy consumption can significantly differ.
When Can You Use JV3 Modelling and Assessment?
JV3 modelling can be utilised as an alternative solution when a section J report is needed. This applies when a non-residential building’s complex design doesn’t meet the Deemed to Satisfy (DtS) requirements under the National Construction Code (NCC).
JV3 assessment allows much more flexibility with the design choices. The designers and architects can create a design as they see fit as long as it doesn’t surpass the reference building’s energy consumption targets.
JV3 modelling is almost similar to a non-residential equivalent of NatHERS modelling. It allows flexibility for choosing building and glazing elements as long as it stays within the annual energy consumption limit of the Deemed-to-Satisfy (DtS) building.
The JV3 assessment involves a detailed evaluation of the building’s design. In the detailed design’s development, the feedback given from the JV3 model needs to be considered.
11 Benefits Of Implementing JV3 Modelling
Provides flexible energy compliance standards to the NCC.
A proven method to reduce construction costs.
Allows implementing low-cost energy-saving measures while replacing high-cost (e.g. single-glazed windows instead of double glazed).
Has no limitation in applying customised glazing options and building material.
No insulation required for enveloping walls above ceilings in the roof area.
Allows offsetting the building’s energy demand using onsite renewable solar systems (solar hot water or electricity).
Allows offsetting the installation of low-cost HVAC solutions with similar low-cost energy efficiency measures. Your HVAC designer can utilise the estimated hour-by-hour energy demand from different building zones for performing a preliminary design and hourly feasibility assessment with other energy system options.
Increase/ reduce insulation in certain areas and substitute it with changing insulation somewhere else in the building fabric.
Reduce/increase the amount of light you’ll allow inside the building by adjusting the glazing’s SHGC factor to your desired value.
Implement higher levels of artificial lighting power density than allowed by NCC.
Optimisation or reduction of screens or external shade projections
