Hmmm ... if that's what you want prove from the start, free to you ...Eric54 wrote:[...] In short we come back to what I said at the start:
the wood stove is not a recognized heating system for RT2005 and the design office with which I work is competent.
I still think that there are other tracks and that your BE is looking above all for ease ...
Sorry, your interpretation is wrong: a passive house (and which functions as such ...) has not needs of heating ! On the other hand, to comply summarily and without getting tired of convoluted regulations, it is possible that a BE (and officials of a ministry) tell you that you need one ...Eric54 wrote:[...] So when we say that in a passive house does not need heating ... it is false. You need one even if you don't use it.
Not really the same thing.
I recall this, written yesterday:
Woodcutter wrote:[...] It will be noted lastly that this decree includes appendices, of which IV and V relate to study files for "technical solutions" and for "special cases", to be submitted to the concerned ministry. .
It would surprise me very much that a file concerning a very well insulated house does not pass under these conditions ... It is perhaps just that the BE does not want to get bored, quite simply!

bravo eric for the site
technical question concerning the low consumption house:
what is the recipe for self-insulating screed?
if you insulate from the outside, how do you avoid the thermal bridge coming from the walls, especially in the case of an old house?
greg
I may be disappointed, but I am not an expert in chappe ... Rather than saying a joke, I prefer to be silent.
For our part, it is the slab which is self-insulating, that is to say that we have slabs in EPS (24cm) and we cover with 4cm of concrete.
I don't understand your question about the thermal bridge coming from the walls ...
From the moment you isolate from the outside, the thermal bridges become negligible; this also corrects the losses at the level of the slabs.
The difficulty is the junction between the exterior wall and the roof.

ok, I explain myself again
if I insulate from the outside, I cut the thermal bridges at the level of the openings and the slabs. on the other hand, my walls are in contact with the ground and therefore even if I have an insulated chappe, the cold can rise between the .exterior insulation and the chappe!

it depends if you have a basement or not and its depth.
In any case, before the cold crosses the foundations ... it can happen decades ...
We lowered the insulation below ground level.
I think that "the rise of cold" by the base walls are minimal because of their small surface.
Besides, I never asked myself this question ...
Maybe experts can explain it to you better than I can ...

To avoid the cooling of the subsoil, it should be heated during the summer. A solar thermal collector that would power a system of coils under the house.
Depending on the depth and the speed of heat diffusion, we would have a basement that would warm up in winter.
Heat storage was mentioned here: https://www.econologie.com/forums/geothermie ... 86-40.html

I come back to this post because I found some interesting info on the EFFINERGIE website.
I quote :
So I confirm what I said before: a BE which says that it is not possible to have compliance with RT2005 with a wood stove just don't do their job !!!
I quote :
Treatment of specific cases at RT 2005: Title V commission for an operation
In the case of a BBC-Effinergie labeling request (whatever the certifier: Cequami, Promotelec, Cerqual, Certivéa), if a system is not taken into account in the Th-CE calculation rules of the RT thermal regulation 2005 (example: wood stove, thermodynamic water heater, Canadian well, etc.), the Title V commission offers the possibility of taking it into account subject to justifications. The contracting authority must submit an application for approval of the construction operation to the Title V commission. This procedure remains flexible and responsive.
The steps for dealing with a particular case are as follows:
Creation of the application file.
The applicant compiles the supporting documentation for the request in the manner defined in Annex V to the decree of May 24, 2006 or in Annex V to the decree of June 13, 2008 depending on the case concerned. In his file, the applicant indicates whether the request concerns a construction or extension operation, a renovation operation or a Title V file dedicated to an energy product or system. In the latter case, the applicant will indicate whether his request relates to an adaptation of the TH-CE rules, the TH-CE ex rules, or both (see also details in the appendix to this document);
Sending of the request for Title V.
The applicant sends his complete application file by mail to the Director of Housing, Town Planning and Landscapes, destined for the QC1 office. This sending must imperatively be doubled by a sending of all the documents of the request file in computer version to olivier.servant@developpement-durable.gouv.fr and charles.pele@cstb.fr.
Request from the Committee of Experts.
The Directorate of Housing, Town Planning and Landscapes requests the opinion of a committee of experts, the "Title V committee", issuing an opinion on the technical relevance of the request,
Possible exchanges
Possible exchanges between the Directorate of Housing, Town Planning and Landscapes and the applicant in the event of necessary supplements following the "Title V commission", www.developpement-durable.gouv.fr.
Possible approval of the request.
Depending on the conclusions of the "Title V commission", the Public Authorities decide whether or not to approve the request. If the decision is positive, the request is approved:
In the case of a Title V request dedicated to an operation, by letter from the Director of Housing, Town Planning and Landscapes to the requester,
In the case of a Title V request dedicated to an energy product or system, by order of the Minister in charge of construction,
For approved Title V requests dedicated to an energy product or system, making available the conclusions of the approval file on the website of the ministry in charge of construction and on the site www.rt-batiment.fr.
Documents to download :
Summary sheet - Request for Title V for an operation
Note on the treatment of special cases in the thermal regulations of new and existing buildings and in the HPE labels
So I confirm what I said before: a BE which says that it is not possible to have compliance with RT2005 with a wood stove just don't do their job !!!
