Re: [EnergyPlus_Support] Insulating wooden floor raised 400mm from ground in temperate climates

Tell them the South African says they should stop whining and toughen up.

The Australians and South Africans are friends at home and enemies on the Rugby field. Each thinks they are tougher than the other.

We both often don't have heating even though the mornings are cold. The style of houses are similar. The 1907 house I grew up in also had this raised wooden floor, but ours was not vented to outside but vented to the zone. For us the house windows were open all daytime so the was enough ODA and no moisture problems. And no insulation. Maybe close the ODA vents and make zone vents to the floor plenum.

i have a 12 m x 12 m single storey with wooden floor. This house is located 37.7 degrees south of the equator on the eastern side of a very big land mass. The temperature and wind varies widely, and this location is tooted to have 4 seasons in a day. Its getting expensive to maintain and operate a gas heater with ducts to the 6 compartments of this 54 yr old house.

The floor is raised 400-500mm above ground level. The house is of brick veneer and the bricks go down at least have a meter into the ground. Dr Li suggested 1 m insulation around the perimeter both horizontally and vertically. Since the air space below the floor is vented to the outdoor air which can go down to 5C in winter months, i doubt this is sufficient to make the occupants not having to wear socks or slippers.

i am also looking for economical floor insulation for a proposed 6.3m x 3.4 m nanny house separate to the above building. Any better suggestion than looking for cheap underfloor insulation/s?

All the best to everyone, ooi
