It IS a no-brainer. Domestic heating is a major component of energy demand. Lower this specific demand, say, 20% (which is easy to do by remodelling more energy efficient homes), and it releases great benefits: lower energy bills for consumers = more to spend elsewhere, C02 reduction, less demand of energy resources = (perhaps, lower prices), and labor intensive employment for the remodelling.

That 20% reduction for homes would mean quite a chunk of savings. My guess is that many people would be very happily surprised and thus perhaps become more aware and supportive of other needed energy reforms.
