Green Roofs - Living Architecture Monitor - Fall 2017 - 20
"Thanks to the Restorative Design Collective, the
Bertschi Living Building Science Wing is a model for
sustainability in construction, and has challenged
our industry to push for more net-zero buildings in
our region and beyond."
- Chris Toher,
Skanska Executive Vice President
and Seattle General Manager
"The Living Building Science Wing will allow
students to expand upon current components of
the science and sustainability curriculum, such as
rainwater harvesting and solar energy. In addition,
students will learn about passive ventilation,
net-zero water and net-zero energy consumption,
concepts that will push their thinking and
understanding decades into the future!"
- Brigitte Bertschi,
Head of Bertschi School

A MODEL FOR THE WAY WE APPROACH
THE BUILT ENVIRONMENT
T
he Green Wall was designed as an integral component of The Bertschi School
Science Wing, with a primary role of meeting the Water Petal requirement of
the Living Building Challenge (LBC). Located in Seattle's Capitol Hill Neighborhood, the project was one of the first in the world to pursue the Living Building
Challenge v2.0 criteria.
This non-profit elementary school science wing was collaboratively designed
with the students and designed pro-bono by the entire design team. A 20-kilowatt
PV system produces all of the electricity for the building and allows students to
participate in real-time monitoring of the building's energy use and solar power
production. All the water needed for the building is collected and treated on site.
This is done through a variety of methods including cisterns for storage, an interior
green wall which treats grey water and a composting toilet to treat black water. The
most important aspect of the project is that all sustainable features are visible and
functional to students to learn ecological concepts that can become intrinsic values
for future generations.
The Water Petal of the LBC requires 100 per cent of stormwater and building water discharge to be managed onsite. Greywater from the classroom sinks flows down
the drain, through an initial filtration system (Aqua2Use filtration units) and then is
pumped to the green wall with distribution through an embedded (red list compliant)
drip irrigation system. The plant material, selected for its hardiness, tolerance of low
light, and ability to absorb water from the soil, uptakes the greywater and disperses it
through evapotranspiration. The wall is a key feature of the Eco-haus, designed as a
demonstration space to meet the 'Beauty' Petal which includes imperatives for Beauty
+ Spirit and Inspiration + Education. An education facility for pre-k through 5th
grade, each of the sustainable systems is expressed, through design, as a visible living
learning tool for the students, who measure and monitor performance of the green
wall, rainwater harvesting cisterns, and other key features of the building.
Intended to be a model for the way we approach the built environment, the
project is open for weekly tours by neighborhood residents, parents, and design
professionals and has received thousands of visitors in the short time that it has been
open. The judges praised the project's connections to water and research, varied plant
palette, as well as its integration into a larger system.
Visit this project in a tour during CitiesAlive Seattle, September 18-21, 2017.
