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 | 503 kWh | $10/mo | $116/yr |
| Reference consumer setup | 964 kWh | $18/mo | $222/yr |
| Lightly insulated / exposed | 1,633 kWh | $31/mo | $375/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 | $210/year |
| 50°F | $222/year |
| 45°F | $235/year |
| 39°F | $253/year |
