The bigger problem is all the homes built in the 1950's through the 1970's, before energy efficiency standards were adopted. The only way that a comfortable environment can be maintained is through active HVAC systems- requiring energy expenditure. This is not a short term problem. This does not need to be your problem in your own home. Plan for energy efficiency in your construction.
Passive systems are the key- design, insulation and construction method are critical.
SIPs are part of the answer. Architectural trends are quick to change. For example, on a summer afternoon with a 90 degree F outside temperature and cooler inside temperature, the conduction heat flow moves toward the inside. Consistent volume compared to insulation voids, compression and aging. More consistent interior temperatures.
