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 | 552 kWh | $6/mo | $74/yr |
| Reference consumer setup | 1,070 kWh | $12/mo | $144/yr |
| Lightly insulated / exposed | 1,872 kWh | $21/mo | $251/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 | $134/year |
| 50°F | $144/year |
| 45°F | $154/year |
| 39°F | $169/year |
