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 | 584 kWh | $14/mo | $174/yr |
| Reference consumer setup | 1,136 kWh | $28/mo | $338/yr |
| Lightly insulated / exposed | 2,010 kWh | $50/mo | $598/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 | $309/year |
| 50°F | $338/year |
| 45°F | $370/year |
| 39°F | $408/year |
