Green Roofs - Living Architecture Monitor - Fall 2017 - 14
RECONNECTING PEOPLE TO MODERN
ENVIRONMENTAL CONCERNS
T
he state-of-the-art Visitor Centre in Vancouver re-connects people to the
environmental issues of the 21st Century including water and energy conservation, re-use and recycle, beauty of our native plant ecology, and a healthier way
of building and design. The overall scope was five acre site master plan including a
16,000-ft2 green and blue roof.
Inspired by the form of a native orchid leaf, the VanDusen Botanical Garden
Visitor Centre forges a unique relationship between architecture, landscape, and
ecology to create a landmark facility. The dynamic roof is the cornerstone of the
building's water conservation strategy with six individual undulating roof petals; two
blue roofs for water collection and solar hot water tubes and four petals planted with
living roofs. The restorative planting strategy is inspired by the Pacific Northwest
Coastal Grassland communities featuring custom fescue grasses with native perennial bulbs and sedums. 100 per cent of site runoff is managed on site for a net zero
water runoff facility.
The roof itself is shaped and divided like the orchid leaves. The green roof was
carefully planned to reflect the Pacific Northwest Coastal grassland community
and includes over twenty species of native plants, bulbs, and grasses. The unique
undulating roof planes simulate rolls and hummocks with gentle slopes of 5 per
cent to near vertical grades. The variety of solar orientation creates multiple opportunities for grassland/bulb plant communities.
Green roof runoff is directed to an existing stream, enhanced infiltration beds,
and wetlands in addition to underground cistern. Key sitelines were established
from the main arrival bridge, upper terrace, restaurant, and street and throughout
the gardens to reinforce the importance of the roof to the image of the project.
The project is certified for LEED Platinum and Living Building Challenge (LBC)
2.0. The judges praised the project's connection to greater site systems and integration of ecology and technology.

"The Musqueam people like all Aboriginal people throughout the world lived in
harmony with nature. We have respect for all life: we respect the plants that provide
the medicines that heal our body; give our body nourishment through the foods that
we eat; that clean the soil and water; and clean the air that we breathe."
