1.How should heating and cooling degree hours be determined?

Use NCC Values (Limited to 69 locations)

Determine values based on climate file and project location

2.How should annual average daily outdoor temperature range be determined?

Determined by the modeller

Determine values based on climate file and project location

3.What level of automation is desired for Specification 44 calculations?

Fully automated

Determined by modeller

4.Should climate files be standardised to a specific file type?

Typical meteorological year (NatHERS 83 Australian locations)

Typical meteorological year (A single period - i.e 2004 - 2018)

Typical meteorological year (Any period)

5.How should window openings be treated in simulations?

Configure as elsewhere in the NCC (i.e. Specification 45 Section 3)

Enable full control for warmer climates

They should be ignored
