BLDGTYP · PASSIVE HOUSE DESIGN & CONSULTING

Your Passive House questions.
Answered.

Passive House design and consulting for architects, developers, and builders. We model the answers so you can build with confidence.

ENERGY MODELING

Know before you build

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.

THERMAL BRIDGES

Find the hidden losses

3D finite-element thermal bridge modeling identifies where your envelope is bleeding performance — before construction begins. Every junction, every connection, quantified.

CERTIFICATION

Cross the finish line

PHIUS and PHI certification support from schematic design through final verification. We handle the modeling, the documentation, and the review process.

ARCHITECTS

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

DEVELOPERS

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

BUILDERS

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.

1
SHARE YOUR PLANS

Send us your drawings at any stage — from early sketches to full CDs. The earlier we're involved, the more impact we can have.

2
WE BUILD YOUR MODEL

We create a detailed energy model of your building — every wall assembly, every window, every mechanical system — in WUFI Passive or PHPP.

3
REVIEW TOGETHER

We walk through the results with your team. Where is performance falling short? What are the most cost-effective upgrades? Real numbers, real options.

4
YOUR REPORT

You receive a comprehensive design-phase report — a complete snapshot of your building's energy performance, with clear recommendations.

5
BUILD WITH CONFIDENCE

Construction proceeds with a fully documented performance target. We support you through certification and final verification.
