Yes, thermal mass takes longer to heat up, and similarly longer to cool down. Currently a compromise is "radiant floor heating" where you insulate the bottom and sides of a concrete floor slab embedded with pipes for hot water to flow through. Heating the "slab" is more efficient than heating "air". Air heats quickly, but doesn't hold any heat, so as soon as the furnace turns off, it starts to feel chilly again. Heating a mass be it floor, walls or dirt under a waterproof "umbrella" such as is discussed in the WOFATI experiments at Wheaton Labs, all provide "slow-release" heat. Depending on how it's done, it takes longer to "charge it", longer to "fill it with heat" but then it keeps the house a comfortable temperature for hours, days or in the WOFATI experiments essentially permanently (humans give off heat, and so do many things we do, like cooking, so the WOFATI is getting heat from that as well as solar gain - the goal is just to not be having to add heat for heat's sake).

I just purchased a book for more information on building but I would like to know. I wanted to do a square structure, not a dome. I planned to make the roof with wood instead of earthbags and have a slanted roof. I just dont like the look of the dome roofing.
Also I do plan on living here many years. If I buy a new house in the future I'll pass this on to my children or my younger sister.
