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 | 509 kWh | $10/mo | $125/yr |
| Reference consumer setup | 976 kWh | $20/mo | $239/yr |
| Lightly insulated / exposed | 1,660 kWh | $34/mo | $407/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 | $226/year |
| 50°F | $239/year |
| 45°F | $254/year |
| 39°F | $275/year |
