VanDusen Botanical Garden Visitor Centre*
Vancouver, BC, Canada
17,222 sq. ft. Greenroof

Project of the Week Mini Description & Details

Located in the heart of Vancouver, BC, the spectacular 22-hectare (55-acre) VanDusen Botanical Garden is renowned internationally for its beauty and for leadership in plant conservation, biodiversity and sustainability. Exceeding LEED Platinum standards, the Living Building Challenge certified VanDusen Botanical Garden Visitor Centre uses renewable sources found on-site to meet net-zero energy annually.

Photovoltaics on the roof create electricity for the Centre, and hot water is provided by a biomass boiler fed by dry wood waste reclaimed from the surrounding area. Rainwater is filtered and used for the Centre’s greywater requirements; 100% of blackwater is treated by the on-site bioreactor.

Designed by Perkins+Will and Cornelia Oberlander with Sharp and Diamond Landscape Architects (now Connect Landscape Architecture), the dynamic single-story structure includes an innovative prefabricated roof form that appears to float above the building’s curved rammed earth and concrete walls.  The Centre was inspired by the leaves and flower of an orchid. The undulating green roofs are located on the “petals” and are planted with grasses and colorful bulbs. The multi-petaled structure’s circular space is topped by a daylit oculus with a slope over 45 degrees which also serves as a solar chimney that exhausts hot air.

With slopes ranging from 2 degrees to 50 degrees, this project used three different greenroof systems: the “ZinCo Perennial Garden,” “ZinCo Sloping Meadow,” and the oculus roof with a slope of more than 45 degrees which was installed with the “ZinCo Steep Sloping Meadow” system including the Georaster elements for growing media retention. The vegetated land ramp connects the greenroof to the ground plane, encouraging use by local fauna and promoting biodiversity. The multi-award winning VanDusen Botanical Garden Visitor Centre is truly a living building embracing bio-mimicry and is open to the public daily.

Publisher’s Note: The VanDusen Botanical Garden Visitor Centre is a featured project at the 2017 Greenroofs & Walls of the World™ Virtual Summit, highlighted in the “Top 10 Green Infrastructure Eco-Agents in a Climate-Changing World” video by Linda Velazquez.
