Our Passive House Construction Process
Passive House Consultation
We meet to discuss your goals, site conditions, and budget. We explain the Passive House standard and how it applies to your specific project.
Energy Modeling & Design
Using PHPP (Passive House Planning Package) software, we model your home’s energy performance and design the building envelope, window placement, and mechanical systems.
Material Specification
We select healthy, non-toxic, low-carbon materials—from structural insulated panels to triple-pane windows—sourced for the Pacific Northwest climate.
Precision Construction
Our trained crews execute the build with meticulous attention to airtightness, thermal bridging, and moisture management. Every detail is verified with testing.
Certification & Handover
Final blower door testing, energy performance verification, and Passive House certification. We walk you through your new home’s systems and hand over your 5-year labor warranty.

Frequently Asked Questions
What is the Passive House (Passivehaus) standard?
Passive House is an international building standard focused on dramatically reducing energy use for heating and cooling—typically by 90% compared to code-built homes. It achieves this through super-insulation, airtight construction, high-performance windows, and heat recovery ventilation.
Does Passive House cost more to build?
Passive House construction typically adds 5-15% to the initial build cost compared to code-minimum construction. However, dramatically lower energy bills, reduced maintenance, and higher resale value mean most homeowners see a net positive return within 7-10 years.
Can you build a Passive House in Seattle’s rainy climate?
Absolutely—Seattle’s mild, wet climate is actually ideal for Passive House construction. The airtight building envelope prevents the moisture problems that plague many Pacific Northwest homes. Heat recovery ventilation provides constant fresh air without letting in humidity.
Can an existing home be retrofitted to Passive House standards?
Yes, though a full Passive House retrofit (EnerPHit standard) is more complex than new construction. We evaluate each home individually—sometimes a deep energy retrofit achieves 70-80% of Passive House performance at a fraction of the cost.
