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	619 kWh	$8/mo	$99/yr
Reference consumer setup	1,218 kWh	$16/mo	$194/yr
Lightly insulated / exposed	2,211 kWh	$29/mo	$352/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	$179/year
50°F	$194/year
45°F	$210/year
39°F	$230/year

Reference scenario

Monthly climate and cost profile

Daily low/high normals become positive cooling degree-hours; provisional pages use approximate profiles until NOAA retrieval succeeds.

January	37–59°F	71 kWh	$11
February	41–64°F	68 kWh	$11
March	48–73°F	86 kWh	$14
April	54–79°F	95 kWh	$15
May	63–86°F	114 kWh	$18
June	70–93°F	128 kWh	$20
July	72–96°F	139 kWh	$22
August	72–96°F	140 kWh	$22
