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 | 511 kWh | $7/mo | $87/yr |
| Reference consumer setup | 980 kWh | $14/mo | $167/yr |
| Lightly insulated / exposed | 1,669 kWh | $24/mo | $284/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 | $158/year |
| 50°F | $167/year |
| 45°F | $177/year |
| 39°F | $192/year |
