Yet my teacher of ST clearly said that this heat emanates even when we do not use it when we use it or not there is no difference she told us ...

And since I have to develop the energies used in ecological houses I must talk about them but I can say that they are perhaps not so ecological as that;)

In fact 'this is a case, a very small business where we have to respond to a problem by arguing from a truthful element.

[...] We still have to potash the plan and for that we still have to document ourselves to exploit the subject as well as possible. (Every idea is welcomed).
We thought to address first the materials used, then the energies. But I think there are other aspects to deal with.
We plan to make a model, testimonials, samples of the various materials used, etc.

Good evening Marie,

there are some infos on the ecology in the habitat on the site of my box, you will be able to find infos there, I think.

Regarding your job and without wanting to chew your work, I think it is necessary to address at least three points:
- the ecology in the construction of the house, it concerns the materials used and their gray energy, due to their origin or their transformation, their impact on the environment and on human health and also their performance (cold, hot protection , rain, wind).
- ecology in the use of the house, which follows directly from the design of the house, because a house built to be very efficient and healthy will use very little energy, will keep its occupants healthy and will allow them to use few resources (water recovery, energy production possibly)
- the end-of-life ecology of the building, that is to say that the elements used during the construction must be able to be reused, either in the construction of something else, or in energy recovery, or to return to the cycle of the material (recycling, composting, etc.)

Here, for me the really ecological house, that's it ...

I hope it is better in SVT than in thermodynamics !! It's crazy to hear that from a teacher!

And the heat pump pump is the groundhog that activates it?

And since I have to develop the energies used in ecological houses I must talk about them but I can say that they are perhaps not so ecological as that;)

Excactement! These are houses that we call ecolo pipo as we just saw on France2: https://www.econologie.com/forums/maison-eco ... t6352.html

Listen to the lumberjack advice, they are very wise!

Hi Marie.
I agree with Bucheron's opinion and I would like to develop his second point, by emphasizing the following parameters, which I let you discover via the net:
-bioclimatism or the integration of the house in its environment
-the advanced insulation of the house, both at the level of the walls, floors, roofs and glazing (or even passive house); saving energy is good, not consuming it is better; you can therefore talk about insulators and in particular natural insulators, requiring less gray energy for their manufacture and healthier for health, you can talk about the evolution of glazing, double and low emissivity, or even triple as of now and generalized in near future. You can also talk about future construction standards since the State is considering a "positive energy" standard for new constructions from 2020, ie a house would produce more energy than it needs. https://www.econologie.com/forums/maison-a-e ... t5870.html .
FYI, in Germany and Switzerland today, building permits are only granted for projects of houses with insulated exterior walls with 15 to 20cm of insulation.

For geothermal energy, Christophe is a little harsh with your teacher, it is normal that she believes like everyone else in this "free and inexhaustible energy"; it seems indeed to be the right vein since it produces the same amount of heat as an electric heater for, on average, 3 times less electricity. In addition, it makes it possible to sell new products, to renew the fleet of fuel and gas boilers, to help the development of small businesses through subsidies (which come from our tax money) and therefore to increase collections. various, employer, employee, regional and VAT of course. Without forgetting the electricity consumption which will increase to benefit EDF and the nuclear branch (beware of the increase in electricity prices when everyone will have their heat pump because other plants will have to be built). In short, it turns money, banks, loans, ....

I still forgot qq something that I add afterwards, is that geothermal energy can be done in the same way as another heating mode, if you have a passive house. This obviously generates less tax revenue, less commercial transactions, but it is an approach to sustainable development, a reasoned way of thinking based on better thought out consumption.

Now, what you can do is compare performance between the primary energies needed to produce either heat or electricity.

When you heat water with a fuel or gas boiler, the efficiency of your boiler is around 90%.

When you produce electricity that will heat your water, the yield is much worse; indeed, to produce electricity, it is necessary to produce water vapor which will make turn an electric generator; the yield is then 33 to 45% maximum http://fr.wikipedia.org/wiki/Centrale_nucl%C3%A9aire since a good part of the transformation of primary energy (hydrocarbons or nuclear) goes into unused heat (cooling towers). Then, the transport of electricity via the different power lines also generates significant losses. At least to avoid this, you should develop cogeneration (you can also develop this).
With your geothermal or aerothermal energy, you have a yield factor of 3 (COP), ie you recover part of the energy that was lost during the production and transmission of electricity, which is not so wrong.

But for now, the highest yield in the transformation of primary energy remains that of energy into heat, this is why we could move towards domestic energy production units heat / electricity (cogeneration) in each house.

Well ben bham

If with all that you have just advised him and after many nights of research on the many and different subjects covered

She will end up expert .marie

You have no more excuses. Marie
Go ahead go

ciaio

[Christophe]

No, she must not push too far ... she will shame her teachers by showing that she knows more than them And they generally don't like ...

Not true Remundo (well in your case I think you are above the average proficiency of teachers ...)

[Gregconstruct]

And the heat pump pump is the groundhog that activates it?

No, the groundhog she puts the chocolate in the aluminum foil

Otherwise, the student often exceeds the teacher and we are there to help!

Thank you ^. ^
For the moment all of this still seems unknown to me but with all your advice and the research that we are going to carry out I think that we will make good use of the subject ^^

Did you see on Tf * 1 the summer shows on green houses?
What do you think?

Biiz and thanks again

[Remundo]

No, she must not push too far ... she will shame her teachers by showing that she knows more than them And they generally don't like ...

Huh? They talk about me ?
Ah yes, yes, don't show the teacher that you know more than him
More seriously, I believe that the main thing is to state things clearly and without pretension. In TPE, it often happens that teachers are "overwhelmed" in terms of skills, because they are generally not very versatile outside the subject they teach.
