What Our Clients Say

“Tadashi and Evergreen Certified have been great to work with! Tadashi has his finger on the pulse of the latest developments in residential green products and techniques, and great industry contacts. I intend to use Evergreen Certified on my next five star green townhome project!”

-Jonathan Mckee/Built Green 5 Star Developer/United States Olympic Gold Medalist (Sailing)

“Dwell Development has been working with Tadashi Shiga since 2009, and ever since this first encounter, Dwell homes have never been Greener.
He is a major part of all we do at Dwell Development, and one of the main reasons we continue to grow or business model.
Tadashi’s expertise in energy efficient home construction, his passion for his craft, and his commitment to helping Dwell Development become the leader in building the most energy efficient homes in the North West is invaluable to us and what we do as a design/build firm here in Seattle.
He is involved from the beginning design phases of the home…through the entire construction process…and then performs all the 3rd party energy verification and reporting for our homes.
Tadashi brings us cutting edge construction techniques, as well as new innovative green materials and concepts that we get to incorporate into all our projects.
He is my right hand man, and I can honestly say that Dwell Development would not be where we are today without the partnership, friendship and commitment that Tadashi brings to our Development Team!”

“I’m lucky to have Tadashi Shiga,Evergreen Certified, as the Built Green Verifier for this project. Extending well beyond the role of verifier, Tadashi provides pragmatic, cost effective strategies for high level sustainability. At our preliminary project meeting we were into the nuts and bolts of products and techniques.

Tadashi has an active, longstanding interest in passive house and was an early supporter of Passive House Northwest. Along with his work as an energy efficiency consultant, he provides real estate services for sustainable building developers, and is developing the Eco CoOp – a bulk purchasing cooperative that provides small and midsized developments with lower cost access to sustainable building products.”
