and energy use in comparison with similar premises:
1 credit where annual energy use is ≤ 40% cumulative percentage.
2 credits where annual energy use is ≤ 30% cumulative percentage.
3 credits where annual energy use is ≤ 20% cumulative percentage.
4 credits where annual energy use is ≤ 10% cumulative percentage.
or, energy use reductions as demonstrated by billing/metering data:
1 credit where the reduction in annual energy use has been 10%.
2 credits where the reduction in annual energy use has been 15%.
3 credits where the reduction in annual energy use has been 20%.
A
SSESSMENT
The number of credits awarded will be determined with reference to the
percentage reduction of CO
2
emissions or annual energy consumption of
the Assessed Building relative to the benchmark (zero-credit) criteria
evaluated from an equivalent Baseline Building model (see Section 8.1).
The calculation shall be done in terms of units of either CO
2
– kg or kWh
per year. A simple conversion factor shall be adopted with reference to
