项目概况:

The VanDusen Botanical Garden Visitor Centre designed by Perkins+Will, covering an area of 17000 sqm, is located in Vancouver, Canada. It creates a harmonious balance between architecture and landscape—from a visual and ecological perspective. The building functions as a community oriented center for the Botanical Garden; it has a cafe, library, volunteer facilities, garden shop, offices, and classroom space for meetings, workshops, lectures and private functions. The form of the Visitor Centre finds a balance between architecture and landscape – composed of "undulating green roof ’petals’ that float above rammed earth and concretewalls", inspired by a native orchid. The roof and ground plane are connected by ramps that promote vegetation – a self-made green roof. The building is primarily constructed out of wood with the roof constructed out of a glulampost-and-beam construction. Rainwater is collected, filtered and used as greywater for the building. The black water is treated by "an on-sitebioreactor and released into a new feature percolation field and garden". The operable glazed oculus may be the most stunning and apparent feature that identifies the building. It protrudes from the landscape created by the roof and produces an atrium space in the interior with a warm orange glow, reflected by the natural wood. This oculus is not just a formal–and eye-catching–move. It assists with natural ventilation; operating as a solar chimney. It also features an aluminum heat sink, which converts sunlight into convection energy,providing air movement through the space. The darker surfaces that absorb more sunlight provide even more ventilation. The Visitor Centre uses on-site,renewable sources, such as geothermal boreholes, solar photovoltaics and solarhot water tubes, in order to achieve net-zero energy on an annual basis.
