Green Hammer

May 3, 2020

As a design-build firm committed to reversing climate change, we see tremendous value for our clients in creating healthy buildings that are third-party certified as being built to a high standard. To achieve Living Building Challenge certification, a project must meet 20 imperatives, including net-zero energy, over a minimum of 12 months of continuous occupancy. Green Hammer is committed to bringing the Living Building Challenge to the Portland and Ashland regions in Oregon. Green Hammer designed and built Oregon’s first Living Building Challenge-certified commercial building.

Incorporating salvaged materials in sustainable construction is an excellent way to offset the pressure on our natural resources. We always take the traditional green construction approach: reduce, reuse, and repurpose first. Then, when purchasing new products, we make every effort to source toxic-free healthy building materials. We are members of the International Living Future Institute and advocates of the Living Building Challenge (LBC). The LBC’s Materials Red List helps ensure that we select healthy building materials for healthy houses and buildings.

Things of note

Green Hammer’s energy conservation engineers and high performance building experts bring equal parts passion and expertise to generate tremendous energy savings and increased cash flow for our clients. With years of experience in delivering Passive House and Net Zero Energy standards to homes, buildings and communities, our expert staff leverage the world’s most cutting-edge energy modeling and hygrothermal analysis tools to carefully evaluate each design decision.

From the design-build and permitting of multiple potable rainwater harvesting systems to innovative botanical water purification and recycling, Green Hammer is experienced in water conservation in our homes and implementing innovative systems.



We meet numerous standards and work with various certifications and training providers. As a green design and construction firm, we view third-party certifications as essential tools for measuring the impact of our buildings. So, it’s only fitting that we would seize the opportunity to become a Certified B Corporation® as a way to measure the social and environmental performance of our business. You can see these all on our website. In 2005, Green Hammer founder and CEO, Stephen Aiguier, co-founded the Build Local Alliance as a way to further support sustainable, green construction in Oregon. The alliance is a non-profit connecting sustainable foresters and their wood products to adjacent urban communities.
