I would like to participate in the "renovation" of my insulation as well as the heating and electricity parts, but this subject only concerns the Insulation / Ventilation part
After having read some post I would like to have answers on the best economic and environmental conformities
here are the characteristics:
Living area 176m²
year of construction 1983 to 1988
One level with attic (ceiling height 2,5m)
Elongated L-shaped detached house
Roof attic (insulation work after 2000)
Sloping roof approx. 20 ° 30 °
No work on the walls
Double glazing installed between 1988 and 2000
Type of median floor (without work)
CMV single flow Hygro A
Walls:
placo ceiling on rails and hangers
insulation in roof spaces by glass wool 200mm thickness with vapor barrier
peripheral insulation by lining of expanded polystyrene panel thickness 70mm

After carrying out an Energy Performance Diagnosis (DPE), here are the results:
My house is in Class D (149 kWhep / m².year) almost 150
and will emit around 26 kg.CO² / m².year and will be in class D in conventional CO2 emissions
My goal is to make my house completely autonomous and even who knows how to resell the energy produced to an electricity supplier (EDF)
My challenges are indeed Environmental and economic!
Here are some ideas after a lot of research
Roofing:
Green Roof (advantages of natural air ventilation, not much labor -about 2 times / year-)
and the formula that I think is suitable and this one (HYDROPACK)
Walls:
I thought to renovate from the outside but according to "toto65" before last post here:
https://www.econologie.com/forums/isolation- ... t3894.html
I quote: "1- polystyrene burns. So I'm not very hot for that.
2-Even if it is armed, mice can get into it. They make incredible galleries. "
So I thought to first change the polystyrene then adapt from the outside
The choice of materials is complicated, I can't do it
glazing:
Passed from double glazing to triple glazing if necessary (I am thinking of doing it)
Air conditioner :
- switch from single flow CMV to double flow or thermodynamic CMV
-Aerothermy (inspiration-expiration) by wall installations (one outside and one inside for example)
Floor :
integrate a heated floor
integrate geothermal energy (recover heat from the ground)

Regulatory standards to be adapted
The RT-2012 standard and the NF P 01-010 standard
> Reinforced insulation of the walls facing the outside
> Good airtightness of the frame
> Treatment of thermal bridges
> Efficient and appropriate ventilation
> Efficient energy equipment

Here I remind you that these are not ideas, nothing is certain, I would like your point of view, according to your knowledge your skills.
Do not hesitate to argue so that I understand and choose accordingly ...
I would like to have clear answers on the choice of materials for the walls, because I get confused.
I remind you that my goal is to reduce the impact of my house on the environment, to make it autonomous (Class A on the DPE) and to reduce my annual energy costs.
Thank you in advance
