Passive Home on Clackamas

Project Overview

Designed as a custom zero-energy Passive House, this residence blends sustainability, performance, and modern design along the banks of the Clackamas River. A high-performance thermal enclosure, EV-ready electrical panel, and 8.4kW solar PV system support efficient, low-energy living. The refined contemporary exterior balances passive building principles with modern design.

Innotech’s Defender 88PH+ Pro windows frame views of the surrounding forest landscape while filling the home with natural light. The Passive House Institute certified window and door system delivers exceptional thermal performance, durability, and air and water resistance — directly supporting the home’s Passive House building envelope and year-round comfort goals.

A final blower‑door test measured 0.041 cfm per sq. ft. of enclosure area, well below the Phius airtightness requirement and a key contributor to indoor air quality, comfort, efficiency—and fire resilience.”

The project also demonstrates how wildfire resilience and building performance can work together. Key strategies to mitigate wildfire vulnerabilities included careful detailing to reduce ember intrusion, continuous air and thermal control layers, durable non-combustible materials, and a highly airtight building envelope. The result is a home that offers greater protection from wildfire threats while delivering superior energy efficiency, comfort, indoor air quality, and long-term durability.

High-Performance Living

Built to meet PHIUS 2021 Zero certification standards, the home incorporates advanced systems including a Minotair Pentacare heat pump and SanCO split heat pump water heater. Durable materials such as dense-packed cellulose and Thermacork insulation contribute to long-term performance and resilience suited to the Pacific Northwest climate.

Leading Certifications

The home holds an exceptional range of sustainability certifications — PHIUS 2021 Zero, EA Zero Energy, DOE Zero Energy Ready Home, ENERGY STAR®, Indoor airPLUS, and WaterSense® — reflecting a comprehensive commitment to energy efficiency, healthy indoor living, and environmental responsibility.
