We have to scale just the ''non-heating'' component, but we don't have exact data on it. Best estimate: assume that the status quo is 50/50 heating & nonheating (similar to residential). So we scale up half of it. | We have to scale just the ''non-heating'' component, but we don't have exact data on it.
