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 | 550 kWh | $7/mo | $88/yr |
| Reference consumer setup | 1,065 kWh | $14/mo | $171/yr |
| Lightly insulated / exposed | 1,862 kWh | $25/mo | $298/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 | $160/year |
| 50°F | $171/year |
| 45°F | $182/year |
| 39°F | $199/year |
