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 | 563 kWh | $7/mo | $84/yr |
| Reference consumer setup | 1,094 kWh | $14/mo | $164/yr |
| Lightly insulated / exposed | 1,926 kWh | $24/mo | $288/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 | $152/year |
| 50°F | $164/year |
| 45°F | $177/year |
| 39°F | $194/year |
