Hi Whistler. Sorry for the late response to your post above.Whistler wrote: ↑January 21, 2024, 2:29 pmI will be building new house later this year, design
Decent slab, proper steel reinforcement on perimeter, waffle pod in floor area (foam battens)
Chilla lapped plank cladding
Internal plaster walls/ceilings with thick foam backing
Vented roof, sarking under steel roof
Wide eaves with Oz style verandah on three side
Sunscreen film on all windows
will install solar.
If I can buy a second hand nuclear plant off a scrapped US warship, I will consider, but parked well away from veggie garden, maybe next to chicken run as having a few 4 legged, glow in the dark chickens will be great.
When I finish, a BBQ where everybody gets a chicken leg and a boost for their pacemakers.
Couple of, ok 3 questions.
Can you choose the orientation of your home.
Why are you using Shera board on your external walls. Very low Uvalue.
We built a basically L shaped structure with the long side pointing North-South. We used 150mm Aerated Concrete blocks on external walls and 100mm on internal, all render finished. Our roof is steel with 30mm of polyurethane foam factory applied which is brilliant for stopping radiated heat getting into the roof space. We have large roof overhangs which are also vented. We also built a car port along the whole length of the west elevation. The bedrooms and man cave are on the east side of the house and are only exposed to direct sunlight for about an hour or 90 minutes when the sun gets up above the shading tree's and when the roof overhangs start to block out direct sun rays. The west side which includes a Thai style kitchen and BBQ area are only exposed to direct sun rays for approximately an hour-90 minutes when the sun drops down as it is setting. I have never found the walls to get above ambient temperature. If you are new building then orientation, shading tree's etc along with high Uvalue build materials help massively to keep the house from overheating due to radiated heat from sunlight. Shading on windows? Mate retro fitted his house and it went from a bright open feeling to a quite gloomy enclosed space, better to use external shading if your windows have long exposure to direct sunlight.
Just my tuppence worth and hoping it helps.
