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 | 488 kWh | $11/mo | $135/yr |
| Reference consumer setup | 930 kWh | $21/mo | $257/yr |
| Lightly insulated / exposed | 1,558 kWh | $36/mo | $431/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 | $244/year |
| 50°F | $257/year |
| 45°F | $272/year |
| 39°F | $292/year |
