Scenario range
One city, three plausible setups
These are sensitivity scenarios—not a confidence interval. The reference setup is the ranking standard.
| Setup | Annual energy | Monthly average | Annual cost |
|---|---|---|---|
| Efficient insulated | 543 kWh | $10/mo | $118/yr |
| Reference consumer setup | 1,051 kWh | $19/mo | $229/yr |
| Lightly insulated / exposed | 1,829 kWh | $33/mo | $398/yr |
What colder targets change
Lower settings increase positive temperature degree-hours and chiller runtime. The same reference configuration is held constant.
| Target | Reference cost |
|---|---|
| 55°F | $215/year |
| 50°F | $229/year |
| 45°F | $245/year |
| 39°F | $267/year |
