KAI Assembly – PDF Version
The KAI Assembly in PDF is a Best Practice Guide for High-Performance Building Enclosures in Cool Temperate & Cold Climates (ASHRAE Climate Zones 4 – 8) where space heating requirements dominate. Includes 14 building enclosure assemblies to construct a high-end home with Passive House principles in mind.
- Two separate air barrier systems in Wall Type 1 (W1) to achieve extraordinary airtightness.
- All critical air barrier materials are clearly labelled.
- Primary air barrier materials are in red font.
- Cost effective constructability and locally sourced materials.
- R-Value Analysis with an effective R-value for each assembly for energy modelling or building permit application requirements.
- Moisture management guidance is provided with the water-vapour permeance of each material and vapour retarder class notifications.
