Self-construction bioclimatic house in wood frame

[syncro44]

Bonjour à tous

I know there is a lot of post that interests me a lot but to gain a little time (I do not have much) I would like to gather as much advice as possible for a bioclimatic and ecological self-construction wood frame, plus wood siding ( am not good at plastering) on ​​piles (sloping ground)

I think in addition that to gather everything would arrange the world

the main issues: floor insulation, walls, roofing
materials (kind of wood and where)
energy
sanitation
rainwater recovery
heating
area (even foot or floor)

already thank you for your answers

I have never understood the interest of pilings for bioclimatic houses ...

On the contrary, who says "air" floor means increased heat exchange with the outside and therefore colder in winter and warmer in summer ...

So is not it better to seek to bury rather than to get up in the air? In addition when we see the PRICE (posed) politis ...

Of course, it's less about the look ... but it's the thermal efficiency that prevails over a non-bioclimatic house?

So are you sure the piles are the right solution thermally?

Hello,

Already a bioclimatic house is conceived according to the climate where it will be.

You look in the Gard, so we'll have to think about summer comfort ...
But you have to tell us more about the immediate environment: solar masks, presence of morning fog ?, wind, ...)

But already in a few words.
-South orientation, with South facades glazed up to 20% of the living space and solar protection.
- roof slope to the prevailing wind
-a good insulation and dephasing
-the inertia of inertia and still the inertia so house on land full with peripheral insulation. (and there you are badly gone with a house on crawl space and wooden frame.
-a ventilated roof in your corner it can be cool
-a Canadian well
- intelligent layout of the rooms (living room in the South, room in the east stay in the west)
-small greenhouse to the south for preheating indoor air


And I strongly advise a dynamic thermal simulation is the only way to be sure to have a good summer comfort.

Goods.

And I add a layer: in terms of gray energy foundations + pilings + reinforced concrete slab necessarily oversized compared to a slab on the ground, it must be "strong" ...

For eco-construction HQE we will iron!

Some studies say that the gray energy of a home represents is between 50 and 100 years of heating!

So here I am less affirmative.
The classic foundation technique consists of a concrete footing of 50cm * 60cm under all load-bearing walls, which makes a lot of space.
The technique of micro-piles consists of the laying of concrete poles from 10 to 20cm of concrete which rests on the good ground, then we put stringers on its piles, that makes a smaller cubage.

Otherwise your link is not very convincing

[Christophe]

Ah ... well, I would have done better to shut up then?

a) We would have to do the precise calculation of the volume of concrete necessary for one or the other solution if the slab on stilts is in concrete I do not see how piles are advantageous on the economy of concrete ...

Am not a specialist in civil engineering even less foundations but a pile also requires a large footing! The reinforced concrete piles are of rather specific construction probably in precontrain concrete (not poured on place thus) ...

I speak of stilts of 20 to 30 cm of diameter + concrete self-supporting concrete slab ... after there are other realizations possible. I do not know what you mean by micro piles

b) Have you read everything on the link?

There I agree but I'm too lazy to do the math.

I am not a specialist either. But there is no sole micro-piles is all the interest, it is rather concrete pads

b) Have you read everything on the link?

yes he is not very rich, too bad it is a primordial question

[Christophe]

Ok for micropiles: yes it can limit the use of concrete!

yes he is not very rich, too bad it is a primordial question

Yes fundamental even ... but very little known also including via the media (but what does the police?)!

The subject is not locked, we can very well "relaunch" it to complete it ... making an estimation method would not be complicated, complex yes but not complicated ...

It is "enough" to make the "volume" inventory of the materials of a house and put some correction coefficient ... obviously it is easier to do during construction ...

ps: we are rotting this subject

Good evening and thank you for the answers

I did not think to make a slab of concrete (gray energy) on the piles but a wood floor so from the bottom
OSB, planks, OSB, flooring,
insulation between planks +/- 20cm
the wood is already a thermal insulator and air too and enjoy the bottom for storage (wood, water, ....)

I am in the north of Gard south full field with dominant view so not too much morning fog

A+

Sorry but I can not advise you this solution, because you will have no inertia so you will not be able to:
- ensure summer comfort. The best strategy is to have a large heat capacity inside the insulated envelope. In simple it is necessary a house isolated by the outside with heavy materials (concrete, earthenware or raw, stone, ....) inside. As a nocturnal super-ventilation can store the freshness in the walls and enjoy this freshness day. He also see that the greater the exchange surface, the more efficient it is, hence the interest of heavy partitions.
-store the solar contributions, and there is even more worth talking about bioclimatic house, because it is still the basis.
