Our Commitment
Sustainability is not a checkbox. It is embedded in every decision we make from site selection to material sourcing.
01 / Performance
From envelope optimization and passive solar orientation to high-performance mechanical systems, we engineer buildings that consume less without compromising comfort. Every project includes an energy model to verify performance targets before construction.
Energy Modeling
02 / Renewables
We integrate photovoltaic systems from the earliest design stages, not as afterthoughts. Roof orientation, shading analysis, and structural planning are all coordinated to maximize generation and enable seamless installation for both new builds and retrofits.
PV + Storage Ready
03 / Certification
Salmon Safe certification recognizes our commitment to protecting Pacific salmon habitat through responsible stormwater management, reduced pesticide use, and site designs that preserve the health of local watersheds from the ground up.
Watershed Stewardship
04 / Envelope
Green roofs reduce stormwater runoff, lower urban heat island effect, and extend membrane lifespan. We design both extensive and intensive systems tailored to structural loads, climate zone, and long-term maintenance requirements.
Extensive + Intensive
05 / Materials
We specify materials based on embodied carbon, recycled content, regional sourcing, and end-of-life recyclability. Our specification process prioritizes transparency through EPDs, ensuring clients understand the full environmental footprint of what goes into their building.

At Cornerstone, sustainability is at the core of every design decision we make. Our mission is to create high-performance environments that minimize environmental impact while maximizing efficiency, comfort, and longevity. Through a commitment to energy-efficient design, responsible material selection, and carbon-conscious construction, we aim to build spaces that serve both people and the planet.
Our approach integrates solar technology, green roofing systems, and envelope optimization to reduce operational energy demand and extend building life cycles. From concept through construction, we prioritize designs that respond to the local climate, leverage renewable energy, and promote long-term resilience.
By embedding sustainable practices into every phase of our projects, Cornerstone continues to advance architecture that not only performs — but endures responsibly.
