Insulation vs. Thermal Mass
The more extreme the outdoor temperature, the more insulation you will want to slow down the transfer of heat (thermal energy). Thermal mass is great in many applications, but pairs especially well with passive solar heating. In this case you need a high thermal mass material where direct sunlight will hit allowing absorption of free solar energy.
