Passive house roof details.
This reduces the amount of heat lost through the building fabric to a very low level.
To achieve the passivhaus standard passive roofs need high levels of insulation thermal bridges need to be eliminated and the structure itself needs to be airtight.
The vedag roof waterproofing system ensures both comprehensive weather proofing and passive house standard thermal protection.
The membrane would also have a nice air sealing gasket effect after the trusses were set in place.
An affordable passive house pdf using a waterproof peel and stick membrane to wrap over the top of the wall going from exterior sheathing in our case 7 16 zip sheathing to interior side of the top plates seemed like the easiest way to maintain a continuous air barrier at the wall to roof junction.
The irish standard part l 2011 for a traditional roof structure is 0 16 w m 2 k.
This is very close to the passivhaus standard 0 10 0 15 w m 2 k however it still does satisfy it.
These key principles are high levels of thermal insulation passive house windows heat recovery ventilation airtightness and thermal bridging free design.
All mbc passive roof systems deliver a u value of 0 10w m2k.
The house that appears blue was renovated to passive house standards by fabrica718 and this image makes clear that it is leaking much less interior heat than its neighbors.
Principle sketches of flat roofs for passive houses available as downloads in dwg dxf and pdf formats free of charge.
The individual roof type diagrams show the detail associated with each roof type.
Each element must be considered thoroughly and incorporated into the build to meet passive house standards and to remain at passive house standard.
The objective of this book is to provide design goals research analysis systems details and inspiring images of some of the most energy efficient carbon neutral healthy and satisfying buildings currently built in the region.
When achieving these very high standards of insulation.

The main diagram below shows how the three passive elements roof wall and foundation link together.
Passive house details introduces the concepts principles and design processes of building ultralow energy buildings.
Fink truss attic truss the vaulted roof and the flat roof.
The system is intended to be used with reinforced concrete construction with eifs and comprises an exterior insulation finishing system of g eps 0 033 w mk installed using compatible adhesive materials.
