The Vancouver Convention Centre Expansion Project was highlighted in the 2009 Greenroofs of the World(TM) Calendar from in the month of April.

The Vancouver Convention Centre is LEED Platinum certified for new construction by the Canada Green Building Council, the first convention center in the world to receive this highest level of LEED certification. Also known as the Vancouver Convention Centre West, it opened on April 3, 2009 and is truly a model in sustainability for a civic building of this size. Designed by Seattle-based LMN Architects, the Vancouver Convention Centre West features a six-acre green roof, which is the largest in Canada and the largest non-industrial living roof in all of North America (as of April, 2009).

Built over land and water on some 1,000 piles, the Vancouver Convention Centre Expansion Project was completed in late 2008. In order to ensure that the expansion and existing facility are fully integrated, a glass-walled connector links the facilities, providing delegates with exceptional harbour views as well as a seamless transition. Featuring floor-to-ceiling glass throughout the expansion, the green roof is landscaped with more than 400,000 indigenous plants and grasses from the Gulf Islands, providing natural habitat to birds, insects and small mammals. This unique ecosystem is planted over 12″ of growing media, and the vegetated roof is just one of many environmental innovations included in the expansion. Additional highlights:

– The green roof is designed to act as an insulator, projected to reduce summer heat gains by up to 95 percent and winter heat losses by up to 26 percent.
– Canadian Premier Gordon Campbell took part in the final planting, saying “The living roof is going to be something that is recognized around the world.” See related story below.
– The convention centre project was designed to achieve LEED Canada Gold certification, but received Platinum.
– In 2010, the Vancouver Convention Centre West served as the international broadcast and media center for the XXI Olympic & Paralympic Winter Games, and was the focus of attention for millions of viewers worldwide.

The slope of this roof is quite unique and ranges from 3% to 56%. PWL Partnership Landscape Architects Inc. lead the green roof team in developing the design, plants selection, growing medium design, detailing, nursery propagation coordination and installation field review. ILD was brought on board to test the integrity of the waterproofing membrane prior to the installation of the overburden and as a retest after the overburden was installed, resulting in the installation of International Leak Detection’s (ILD) Electric Field Vector Mapping (EFVM) system.

The custom greenroof system includes:
– Metal deck
– DensDeck
– Permaquik Membrane w/ root inhibitor (now owned by Tremco Inc.)
– 4″ extruded insulation
– Filter cloth
– 12″ engineered soil

The Vancouver Convention Centre Expansion Project won the 2010 Green Roofs for Healthy Cities Awards of Excellence in the Extensive Institutional category.
