standard, EER, which measured air conditioners at full capacity. The new metric
will give a more realistic view of air conditioner energy consumption.
Current units meeting the commercial
building energy code have efficiency levels
around 9. 5-11. 5 IEER, whereas the new
standards would set minimum efficiency
levels between 12. 3 and 14. 8. The mea-
sures are estimated to save between $16
billion and $50 billion in electricity costs
over the next 30 years.

units sold starting in 2019.
The measure is estimated to reduce
electricity consumption by around 1.3
trillion k Wh and save the average building owner between $3,500 and $16,500
over the life of one commercial rooftop
Also included in the proposal is a dif-
ferent metric to measure air conditioner
efficiency called the integrated energy
efficiency ratio (IEER).
It measures real-world energy
consumption better than the previous
