Author says "Most of the structure is exposed to air, which is generally much colder than the ground, so I'm going to ignore the floor."
The floor in Boston will be about 40 degrees F in winter. Cold feet are a miserable experience. Foam insulation would be money well spent.
- londons_explore 6y agoThe floor also has a very big thermal mass. It will take days to warm up. After you have spent lots of money warming it up, it will keep the rest of the building warm (and leaking heat through the walls) when you aren't using it, wasting more money. Thermal mass is very bad for any building only used some of the day/week
- saeranv 6y agoIf the floor slab is insulated on the bottom (so you're decoupling it from the earth), and it's around 100 - 200 mm thick, I think it could do some nice passive heating/cooling - cooling the space in the summer and warming the space in the evenings. But, it's true any active heating would also be buffered by any thermal mass (especially radiative heat). But you can just cover up the slab with carpet to limit the buffering.
