Last week, the 1.2 million-square-foot Vancouver Convention Centre West opened in Vancouver, B.C. The project is massive.

Built next to the existing east convention center, the new west building allows the convention center to triple its capacity. it will also be the broadcast media center during the 2010 Olympics where it will host 7,000 members of the media. It cost $883 million in Canadian dollars and was designed by Seattle’s LMN Architects, who partnered with local firms Musson Cattell Mackey Partnership and DA Architects & Planners, who were prime architect.

On the green front, the center is shooting for LEED Canada gold and has two real stand-out features. One is the six-acre living roof, which press materials say is the largest green roof in canada and the largest non-industrial green roof in North America (does anyone know what the largest green roof is in North America, industrial or non-industrial?) You can’t walk around on the roof but there is apparently a viewing space where visitors can see it.

The other is the building’s consideration for local habitats. For example, the team worked with scientists to reduce the building’s impact on marine animals (about half of the structure is built over water). The building has an underwater habitat ’skirt,’ or an artificial reef that emulates a shoreline and provides habitat for barnacles, fish and other sea creatures, in addition to other restorative features.

My question is - does the inside of it feel green? McCormick Place in Chicago, for example, felt just like any other convention center. And having been to a conference in the Vancouver East Centre (which again, felt just like a regular convention hall) I am curious to see if any of the green elements that influenced the west building are visible to the general user.

About a month ago (Jan. 20) I wrote a story in the DJC on the green roof at the Gates Foundation’s garage. At 60,000 square feet or about 1.4 acres, it is the largest green roof in Seattle by a landslide.

The garage is a crosswalk away from Seattle Center on the east side of Fifth Avenue North. It is located next to the future Gates Foundation headquarters and is kitty-corner from EMP. The garage is technically a public-private partnership between the Gates Foundation and the city of Seattle. NBBJ was the architect. Sellen Construction was general contractor. Gustafson Guthrie Nichol was landscape architect.

The roof itself is visible from the Space Needle, a consideration in its design. The roof has five inches of soil over a layer of synthetic drainage. 

Here are photos:

The green roof at Seattle hotel-condo project Olive 8 is being installed this week. It is one of the largest green roofs in Seattle at 8,355 square feet.

The roof is actually two green roofs so the developer, R.C. Hedreen, can test out which system it likes best. Above the chillers there is a sod-based green roof. On the actual fourth floor ground level, there is a tray-based sedum system. There is a lasting argument between which one of these techniques is better, which I will discuss in a later post at greater detail. For more on this project, or to learn about R.C. Hedreen’s conversion to being a green developer, read the story in the DJC here.

R.C. Hedreen is also considering a second green roof on the 39th floor of Olive 8, though if it pursues that option it will need to be sod-based as David Thyer, president of the company, said the city is afraid the green roof trays will blow away at such a great height.

On Tuesday, I was fortunate enough to see part of the tray installation. Here are photos I took of the process:
