Yep cheap energy and modern building techniques made us lose a lot of the common sense of yesterday.
Good thing initiatives like the passive house institute are bringing back some of these principles, you can easily cut a modern home heating/cooling needs by 70%+ by following simples rules
Passive house thinking comes from an era of peak oil concerns, no solar, and no heat pumps. None of those conditions holds anymore. Further, passive houses are notorious for overheating and because they’re so airtight they require expensive mechanical ventilation and make-up air systems unless you want indoor air pollution problems.
People building houses today are much better served by spending their money on solar + battery + heat pumps than going passive.
