Passive House design and consulting for architects, developers, and builders. We model the answers so you can build with confidence.
We model your building's energy performance so you can make design decisions with real data — not assumptions. From envelope to mechanicals, every system is accounted for.
3D finite-element thermal bridge modeling identifies where your envelope is bleeding performance — before construction begins. Every junction, every connection, quantified.
PHIUS and PHI certification support from schematic design through final verification. We handle the modeling, the documentation, and the review process.
Designing high-performance luxury homes
You care about craft, comfort, and precision. We bring the energy science to match your design ambition — without compromising your architecture.
Single-family · Townhouse · Brownstone renovation
Building affordable multifamily at scale
You need certification, incentives, and energy performance that pencils out. We model efficiently and deliver documentation your review team will accept.
Affordable housing · Mixed-use · Multifamily
Getting high-performance details right
You're building it — and you need to know the assemblies will perform. Our standard assessment gives you clear, actionable guidance on envelope details, airtightness, and mechanical sizing.
Single-family homes · Custom builds · Renovations
Send us your drawings at any stage — from early sketches to full CDs. The earlier we're involved, the more impact we can have.
We create a detailed energy model of your building — every wall assembly, every window, every mechanical system — in WUFI Passive or PHPP.
We walk through the results with your team. Where is performance falling short? What are the most cost-effective upgrades? Real numbers, real options.
You receive a comprehensive design-phase report — a complete snapshot of your building's energy performance, with clear recommendations.
Construction proceeds with a fully documented performance target. We support you through certification and final verification.
Assembly Detail · Foundation
Every project receives a detailed design-phase report covering:
CLEAR ENOUGH FOR YOUR CLIENT.
DETAILED ENOUGH FOR YOUR ENGINEER.
We build and maintain Passive House Tools — the open-source toolkit used by Passive House practitioners worldwide. The same rigor we put into our software goes into every project we model.
We work with architects, developers, and builders building to the highest standard. Reach out to start the conversation.
