- Level 4 - uses simplified building energy model (SBEM) software for complex buildings that have more complicated building services including centralised air-conditioning but don't have large amounts of glass and curves.
- Level 3 - uses simplified building energy model (SBEM) software for simple buildings with straight forward building services.
