What nature can teach us about sustainability

Posted on October 29, 2013

The following post is by Kathleen O'Brien:

Shifting perspectives and enriching our view of sustainability is the aim of "Finding the Balance: Restorative Development & Regenerative Design" — a panel to be held November 12th at the Bullitt Center. It will feature local thought leaders: Architect Jennifer Barnes of 55-5 Consulting, Engineer Colleen Mitchell of 2020, and Real Estate Developer Eva Otto of Infiniti RED.

A panel on sustainable development will be held from 5-7 p.m. Nov. 12 at Seattle's Bullitt Center. The event includes a tour of the building.

Barnes will be speaking about learning from and then emulating nature's strategies in order to solve our own problems more sustainably, and her own experience applying the biomimetic framework at the urban scale through the project Urban Greenprint. According to Barnes, "When we live with intention and empathy for the planet and for each other, we will feel more connected with life, which in turn will compel us to live with more intention and empathy."

Mitchell will be discussing her work engineering living systems using regenerative technologies. The venue for the panel is apt, as Mitchell was the "water engineer" for the net zero water project.

Otto will be discussing how traditional feminine values could help us redefine the discussion of sustainable development from a balanced perspective.

The event is sponsored by the Women's Network for a Sustainable Future, the Bullitt Foundation, and The EMERGE Leadership Project, and will include a tour of the Bullitt Center, which was designed to the Living Building Standard.

Kathleen O'Brien is a long time advocate for and prolific writer about green building and sustainable development since before it was "cool."

This is not your grandfather’s heavy timber structure

The following post is by Brad Kahn:

The last few months have been busy at the Bullitt Center construction site on Madison Street, with structural, glazing, mechanical and other systems taking shape.

Glaziers install windows on the sixth floor.

The Type-4 heavy timber structure is a first for Seattle since the 1920's, when heavy timbers were used in most commercial buildings. In the interim, the technology of heavy timber structures has advanced, with glued-laminated timbers replacing solid wood in many cases. Of course, forestry practices have also improved in the last 90 years, with 100% of the wood used at the Bullitt Center coming from Forest Stewardship Council certified forests.

At this point, the structural work at the Bullitt Center – designed for a 250-year lifespan – is largely complete, with the roof firmly in place.

With the structure complete, work turned to the curtain wall. Of particular note, the Schuco window system being used is arguably the most efficient in the world. Yet before the Bullitt Center, these windows were not easily available on the West Coast, since the manufacturer was in Germany – quite a distance to ship windows weighing hundreds of pounds each. To address this challenge, the team was able to connect Schuco with Goldfinch Brothers, a glazing company in Everett, WA. Now Goldfinch is the exclusive manufacturer of the Schuco window system on the West coast, providing windows for the Bullitt Center and other projects.

A rainwater collection and treatment system is being built throughout the project.

On the mechanical side, the rainwater collection and treatment system is being built throughout the project, from roof to basement. While approval to use rainwater for drinking is pending, it is our hope that the Bullitt Center can help demonstrate that ultra-filtration, UV and activated charcoal can treat water as well as – if not better than – chlorine (which can't be use in the project, because chemicals are not allowed for water purification by the Living Building Challenge).

At this point, the Bullitt Center is on track for completion later this year, with occupancy by commercial tenants starting in January 2013. Conversations with potential tenants are underway, and interested companies should contact Point32, the project development partner, for more information.

Brad Kahn is president of Groundwork Strategies. He manages communications for the Bullitt Center project.
