I put this together on MarkStephensArchitects.com last week…
What I’m seeing over the last few years is that even if the client doesn’t go the ‘whole enchilada’ with a certified Passivhaus (I would however highly recommend designing, building and certifying to the Passivhaus standard incidentally); many of the Passivhaus features are becoming incorporated and ‘trickling down’ to the ‘Standard’ project. Namely:
1. High levels of insulation.
200mm cavity with low conductivity wall tie
With the ‘optimal’ cavity width for Passivhaus certification using concrete blocks at 300mm (pumped with platinum multi-bead insulation); we’re frequently adopting cavities on our ‘Standard’ projects of 200mm and 250mm.
2. Minimal Thermal bridges
As you can see in the image above, we are using low conductivity wall ties instead of steel versions.
The photo below also shows the low-conductivity blocks we use in strategic locations to reduce thermal bridging:

3. Triple Glazing
The price for triple glazing in Ireland has reduced…
