Passive house project: discussions and details

[jejed69]

hehe ... you talk about calories received but me chte talks about their origin ^^

>> "preventing the calories received during the day"

received by what? ^^

Hey, you have to read the whole sentence, not just the end:

I think it's mostly due to solar radiation combined with the presence of the atmosphere which constitutes a layer of thermal insulator preventing the calories received during the day from starting again from the setting sun.

thank you I finalized my file for a superb TPE in English ^^ on geothermal energy
Little hint, because I still asked my physics teacher .... basically: we should not talk about calories when we talk about heat, the calorie is a unit as well, what is in the ground is ... heat as well .... the origin ba is: the rise of heat flows from the interior of the earth and when you think about it, we keep saying that it is a system independent of weather conditions and it is said that the exchange is due to the rays of the sun
End good ... here is for this little history lesson and thank you for this little geothermal lesson ^^

the origin ba it is: the rise of heat fluxes coming from inside the earth and when you think about it, we keep saying that it is a system independent of weather conditions and we say that the exchange is due to the sun's rays

Hello
come spend an hour in my veranda at night and an hour in the middle of the afternoon and tell me if it's the volcano that heats or the sun

Hello

It's been a while since I haven't advanced my subject (a little too much work ), so what was my surprise to receive a response notification email!
Jejed, I'm very happy that you were able to get your questions answered, but as Christophe started asking, why did you post a heat / geothermal energy question in a topic on passive house?

Hello, if you are interested I am the Architect of this house. It is indeed a passive house (11 kwh / m2 / year). Mass-produced by a national manufacturer (which partly explains the very tight price).
The final price will rather be around 1200 € m2. Which is already very effective.

Good evening, carchi
What house are you talking about?

[carchi]

From the passive house build on the initiative of Yane Arthus Bertrand.

Hello,

I heard that you have to be wary of radon when you want to do geothermal energy. I am thinking of buying this: http://www.laboandco.com/detecteur-radon-ramon2-2.htm

Anyone of you know this product? Is it true that geothermal energy can bring radon gas into the house?

Little back on the forum I've been on the go for a long time.

Here, my building permit is deposited in town hall.

A small view to explain what it is:



We will be a bio-climatic house.
It is a cube, the best ratio between the exposed surface and the interior volume.
We are less "riding" on these air flows, we try to manage the natural convections of hot and cold air instead.
For us, it will be the creation of a straw wall (between wood on the outside and earth on the inside) 50 cm thick on the wind side. It is a wall that will be porous to the air, but the air that enters will be heated by the wall, and hygro-regulated.

The whole "cube" house is made of wood on the outside.

Ventilation :
Venturi effect (which we see appearing under the roof) for extraction and Canadian well for suction, with grids that can be closed on either side.
No VMC, which is very greedy in electrical energy, throughout the year.

To heat the house, we will have a greenhouse in the south, with a plant screen in front to shade it in summer. Inside, there will be a mass stove, included in a large masonry wall (the mineral part makes the thermal inertia of the house ... because a 100% wooden house has no inertia: that means say that it heats / cools quickly: this is an advantage in winter, but not in summer !!!).
No geothermal energy (off budget .... and not necessarily necessary with a mass stove), but a Canadian well.
Solar panels, for DHW, according to budget.
Large openings on the sun side, and not / little on the prevailing or north wind side.

And above all: a roof not attached to the house. Basically, we build an agricultural building and store a cube of housing underneath. Why ? Because the house will be in the shade of the roof, an additional way to combat the heat in the summer.

"Hyperventilation" skylights on the roof.

The additional heating will be:
- An electric panel
- Electric radiators.
Normally, it's just if you can't handle the wood safely.
And then, we know better how to protect ourselves and fight against the cold than the hot, with the changes to come, it's important to think about it.

Here...
It is extremely motivating, it requires a lot of personal documentation (besides, there is a great article in the magazine "Futur et maison" of this month), and a certain investment of the architect (a friend of family).
It is obviously a house that cannot be conceived without taking into account the environment, our way of life, in short, it is very high fashion!
It is a little (much) more expensive - necessarily - than a house on a concrete block catalog, but frankly, it is a completely different approach.
