Section J - Greenhouse Gas Emission Factors

NCC 2019 - Vol 1 now requires greenhouse gas emissions (kgCO₂-e/GJ) to be used when undertaking Performance Solutions, including JV2 Green Star and JV3 Verification using a reference building. 

It is likely more useful to express greenhouse gas emissions as a function of the floor area, to be more readily comparable to other projects.

You are given the option to either adopt greenhouse gas emission factors as supplied (above) or those within the current full fuel cycle emissions factors published by the Australian Government.

In the case of the ACT, an exception is made where a greenhouse gas emission factor of nil is provided as the national emission factors are deemed not to be applied as they do not take into account investments in renewable electricity generation in the National Electricity Market.

The most important thing is that the greenhouse gas emission factors must be the same for both the Reference Building and Proposed Building within the JV2 Green Star and JV3 Verification using a reference building Performance Solution pathways, so it is a fair comparison and equal comparison of emissions with the same unit in both.
