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 | 493 kWh | $8/mo | $96/yr |
| Reference consumer setup | 941 kWh | $15/mo | $183/yr |
| Lightly insulated / exposed | 1,584 kWh | $26/mo | $307/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 | $173/year |
| 50°F | $183/year |
| 45°F | $193/year |
| 39°F | $208/year |
