Installation details for passive houses

When it comes to Passive Houses, installation details are often overlooked. But from our experience, we have found that it is important to understand that a lot of heat can be lost here (linear transmission loss – psi-value) if this detail is not developed in conjunction with the overall building design.

A well-designed installation detail will typically cut down 0.5-4 kWh/m2/year of the heating demand, which is a significant
proportion of the total allowance of 15 kWh/m2/year (up to 25%).

We have drawings of various installation details suitable for Passive House projects with corresponding psi-values. However, as these vary, we would recommend that the best solution is to have the exact psi-value for your installation details calculated on a project-specific basis.

If an exact calculation is not made then the final PHPP calculation will be defaulted to the conservative psi-value of 0.04 W/m K.
