correction.
6) - Seals between glazing and glazing beads
- use double or triple lip seals

put a chimney (not very compatible with low consumption)
21) - Technical ducts and access doors
- seal between floors and install a seal on the door frame
22) - Wall and air network connection
- seal between sleeve and duct, preferably carry out the
distribution in hot space
23) - Pipe sheath
- seal the gap with acrylic sealant on a cold network, see product
suitable for hot network
24) - Bulkhead connection - exposed beams
- peripheral adhesive tape between beam and partition
25) - Cracks in through beams
- clogging with wood pulp; use non-core woods
26) - Intermittent use fireplace
-check the presence and tightness of a valve
27) - Cold air flow through the electrical ducts
- install the switchboard in a hot space
28) - Electrical distribution network with one end in cold space
- seal at one end (preferably at the outlet of the switchboard) or
the ducts having the terminal end in cold space, by plug of
acrylic sealant
29) - Telephone and TV network
- seal the ducts with an acrylic sealant cap
30) - Junction boxes in cold space
- avoid placing the junction boxes in cold space, or use
waterproof housings and carefully seal the box sheath connection
31) - Openwork recessed electrical boxes
- prefer solid cases to be drilled or those with rubber membranes
32) - Extractor hood
- install a recycle kitchen hood
33) - Garbage chute to cold space
- departure and arrival of the garbage chute in cold space
34) - Lowering dirty laundry to cold space
- arrival in hot space, or equipment to avoid
35) - Central vacuum with central unit in cold space
- equipment whose compatibility with low consumption remains at
check
36) - Built-in mailbox
- equipment to be left in cold space
37) - Connection between prefabricated elements
- design the element by integrating the ability to seal the
liaison; dry joints are often permeable
38) - Door frames on drywall
- carefully seal the edge of the partitions before installing
doorframes
39) --Bookings in walls, slabs and roof terraces
- seal up carefully, including in places with delicate access, if
possible with sleeve sealed by adhesive tape on the structure
40) - Raw masonry walls
- treat with a liquid coating at least on one side
41) - Hatch to undeveloped attic
- joint between frame and opening, connection between frame and frame to be treated (cf.
item 2)
42) - Expansion joints
- careful treatment of expansion joints, over their entire length,
with product adapted to the materials
43) - Step and counter step link on stairs to cold space
- bonding, puttying or adhesive tape on the assembly
44) - Set of elegies
- take care of the manufacture of the male and female parts
45) - Cable tray between hot and cold spaces
- prefer individual clogged passages to grouped passages
difficult to deal with between the elements
47) - Installation of insulation
- ensure uniform contact of the insulation with the finish

This should be qualified, for a French window with 2 leaves an electric motor is ideally placed to open / close the roller shutter and it is less tiring than a manual system in this specific case.

Bonjour,
I self built a passive MOB in France.
I work in Portugal but I come back next year.

Re: Useful summary for airtightness
Thank you for this interesting work.
Using the same approach, electrical repair + VMC Double Flux installation + attic insulation carried out this summer, I would like to take this opportunity to make a few comments.

A little putty and well-designed handles should limit losses at the thermal bridge of the transmission square between the outer handle and the inner handle.phil12 wrote:11) - Through locks
- favor non-through locks with watertight handle on the internal side.
I made the distribution in lost roofs then covered the whole with 35cm of cellulose wadding. I took care of the airtightness of the ceiling crossings with putty, as well as the airtightness of the entire ventilation system.phil12 wrote:22) - Wall and air network connection
- seal between sleeve and duct, preferably carry out the

I installed DCL airtight recessed boxes (to prevent the air from the rooms from leaking into the attic at ceiling level) But I let the air circulate inside the electrical ducts sized according to the standards ...phil12 wrote:27) - Cold air flow through the electrical ducts
- install the switchboard in a hot space.
I kept my extractor hood (much more efficient) but I installed a non-return valve at the hood outlet to avoid the entry of air through the hood chimney when it is off.phil12 wrote:32) - Extractor hood
- install a recycle kitchen hood.
Except for the care to be taken in airtightness of the air passages in partitions, the material (PVC) of the centralized suction network does not favor thermal bridges. The suction network is, in principle PERFECTLY sealed, otherwise suction would be non-existent. I therefore see no incompatibility between this equipment and a passive construction.phil12 wrote:35) - Central vacuum with central unit in cold space
- equipment whose compatibility with low consumption remains to be verified.
Prefer the installation of such a hatch in an unheated technical room. Ideally, this is the garage.phil12 wrote:41) - Hatch to undeveloped attic

Hello Citro,
There I remain on the basic sealing (type of connection, singular points), I do not dwell on the complement provided by the insulation, nor on the thermal strategies.

A horror of complexity of care for the average French pros and therefore inevitable errors and perpetual trials, given already the number of huge errors, with no sealing requested, by the usual pros in France, formerly !!
In addition I doubt the possibility of maintaining sufficient tightness.
In my opinion, we must look for other simple methods, without manic sealing.
