You’d likely expect
to be negative. This is because, generally, as the outside temperature rises (moves above 58°F), the cost to heat the building would decrease since the building would need less heating. Conversely, if the temperature drops below 58°F, the cost would likely increase, reflecting a common trend where heating costs are inversely related to outside temperatures.
