Passive House Construction in Seattle & the Puget Sound
Certified Passivehaus builder delivering 90% energy reduction and Net Zero capable homes.
Passive House Planning Snapshot for Seattle Homeowners
Passive House construction in Seattle focuses on airtightness, continuous insulation, high-performance windows, heat recovery ventilation and verified energy modeling. The goal is a quieter, healthier home that can use dramatically less energy than a code-minimum build.
- Common premium over code-minimum construction: roughly 5% to 15% when planned early.
- Core verification steps: energy modeling, thermal-bridge review, blower door testing and ventilation balancing.
- Best-fit projects: new homes, DADUs, additions and deep energy retrofits where envelope work can be planned before construction.
About Our Passive House Construction Services
Passive House is the most rigorous energy standard in the world, and Love Construction is one of the few certified Passivehaus builders in the Seattle area. We design and construct homes with super-insulated building envelopes, triple-pane windows, airtight construction, and heat recovery ventilation systems that cut heating and cooling costs by up to 90%. Every Passive House we build is Net Zero capable, uses healthy non-toxic materials, and comes with our 5-year warranty on labor. This is not green marketing. This is building science.
- Certified Passivehaus design and construction to international standards
- Super-insulated walls, roof, and foundation with continuous insulation
- Triple-pane, thermally broken windows and doors
- Airtight construction verified by blower door testing
- Heat Recovery Ventilation (HRV) for fresh air without energy loss
- Net Zero energy capable with solar-ready design
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.

Plan the Seattle-area construction scope carefully
Love Construction projects work best when the owner, designer, and builder begin with the same scope, site constraints, access expectations, and decision timeline. Before comparing options, gather the property address, photos, existing drawings if available, notes about utilities and structural changes, and the rooms or exterior areas affected by the work. Confirm which decisions are already approved and which still need pricing, design, or permit review.
For additions, remodels, ADUs, DADUs, new construction, seismic work, and custom interiors, the practical details matter as much as the finish list. Document parking, staging, delivery access, occupied areas, neighborhood constraints, utility shutoffs, and any work that must stay separated from family routines or tenant operations. A clear early brief helps the construction team identify what can be priced from current information and what requires additional drawings, engineering, product selections, or jurisdictional feedback.
Coordinate selections, permits, and handoffs
Keep product selections, plan revisions, finish schedules, change requests, and owner approvals in one current record. Seattle-area construction can involve design review, structural coordination, energy details, inspections, utility coordination, and schedule dependencies between trades. When a choice changes cabinets, windows, fixtures, appliances, layout, framing, or exterior openings, review the connected cost and timing impact before field work depends on the prior version.
At each handoff, confirm the active plan set, open questions, owner-supplied items, inspection status, site access, and the next decision needed. Good construction communication is specific: who owns the item, what information is missing, when it is needed, and what work depends on it. That record protects the project from assumptions and gives the homeowner a practical way to track progress.
Keep construction decisions tied to real field conditions
Before work begins, review how the planned scope connects to the existing structure, utilities, drainage, framing, foundations, finishes, and occupied spaces. A remodel or addition may look simple on a room list while still depending on structural openings, mechanical routing, electrical capacity, weather protection, and sequencing between trades. The owner should know which decisions are cosmetic, which require technical review, and which cannot be finalized until hidden conditions are exposed.
For ADU, DADU, passive-house, new-home, and major remodeling work, the project record should separate confirmed requirements from allowances. Confirm access for crews and deliveries, storage areas, dust control, temporary protection, inspection windows, owner-supplied items, and any rooms that must remain usable. When the home is occupied, name the daily contact and decide how questions, photos, site changes, and approvals will move between the field and the owner.
Close each phase with a useful record
At the end of a design, preconstruction, rough-in, finish, or punch phase, record what was completed, what remains open, and which decision controls the next step. Keep permit notes, product selections, drawings, finish references, inspection results, change approvals, and warranty information with the project file. That habit makes future maintenance, resale questions, and later remodel phases easier to understand.
When a project changes, document the reason, affected scope, cost or schedule implication, and approved direction before the change is built into the work. That protects the homeowner and the construction team from relying on memory during a complex Seattle-area project.
