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 | 583 kWh | $7/mo | $78/yr |
| Reference consumer setup | 1,138 kWh | $13/mo | $153/yr |
| Lightly insulated / exposed | 2,027 kWh | $23/mo | $272/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 | $142/year |
| 50°F | $153/year |
| 45°F | $165/year |
| 39°F | $181/year |
