Passive House standards demand ultra-efficient envelopes — but achieving them requires seamless collaboration between architects, engineers, and energy consultants. At Veitas Engineers, we’ve helped deliver high-performance projects where structure and sustainability work together from day one.
Insulation Changes the Rules
Adding exterior insulation alters more than wall thickness. It affects fastener length, sheathing stiffness, and structural detailing. We review these impacts early to prevent conflicts between cladding attachments and load paths, especially at headers and balcony penetrations.
Thermal Bridges Under Control
Continuous thermal breaks sound appealing, but they aren’t always efficient. We isolate breaks where they matter — balcony beams and penetrations — and handle broader transitions through continuous insulation. This simplifies construction while maintaining energy performance.
Sheathing, Siding, and Strength
Extra insulation affects shear resistance and withdrawal capacity. Our detailing keeps thermal performance and structural stability in harmony — no compromises on strength.
If you’re project requires Passive House performance and you’re concerned about the structural implications, let us know. We’ll walk you through it.
Collaboration Is Everything
The best Passive House outcomes happen when all disciplines share a table. By coordinating structure, energy modeling, and envelope detailing early, we create solutions that are efficient, durable, and buildable.
Watch Out for Insulated Headers!
Most 2×6 exterior wall headers can include up to 1″ of insulation without issue — beyond that, expect design adjustments. Restricting headers to two plies may require engineered lumber, which can complicate Type 3A (5-story) projects where LVLs aren’t allowed in exterior walls.
Performance Without Complexity
Efficiency isn’t about adding layers — it’s about smarter planning. If your next project targets high performance, let’s coordinate early to ensure the envelope performs as beautifully as it looks.
