1 LOCATION Building Type: Multi use assembly center Building Size: 1,076,400 sq. feet (100,000 sq. m) Location: Vancouver, British Columbia, Canada Occupancy Date: March 2008 Application: Wastewater reuse Treatment Plant Size: 1,200 sq. feet (111 sq. m) Capacity: 20,000 gpd (76 m3/d) LEED Rating: Canada Green Building Council LEEDNC Gold 2 The VCC expansion west meets LEED Platinum certification by incorporating many environmental innovations, including an incredible water conservation system, to limit the impact on the local environment. The system will treat 100 percent of the wastewater that is produced in the building, and the effluent will be recycled for flushing fixtures and irrigation of a 6 acre (24,280 sq. m) living roof. 1

2 HABITAT 3 LANDSCAPE HABITAT HUMAN HABITAT MARINE HABITAT In April 2009, the 1.2 million sq. ft. Vancouver Convention Centre West opened and hosted the 2010 Winter Olympics. Built upon a former brownfield that was the last undeveloped piece of property on the harbor front, it functions as an expansion of Canada Place. The facility covers 14 acres of land and eight acres of water, and is connected to Canada Place via landside walkways. It was designed by Seattle based LMN Architects, in collaboration with Musson Cattell Mackey Partnership and DA Architects & Planners, both of Vancouver. SUSTAINABLE FEATURES 4 The Vancouver Convention Centre s west building features some of the most advanced sustainable design features. The building was designed with the goal of qualifying for LEED Gold certification, but received platinum and significant focus has been placed on environmental sustainability including: A 24,000 sq. meter planted roof On site black and grey water recycling system Seawater heating and cooling The most current energy management technology Natural lighting and ventilation Marine habitat in the foundation 2

The system used is similar to geothermal technology, except that a heat pump pipes water from the harbour, and it is the constant temperature of seawater that is used to heat and cool the building. In very cold weather, steam augments the heating system. Demand on the mechanical system is also reduced by the living roof, which acts as an insulator.

In fact, over 80 percent of the building s gray water needs are met in this way. A 10,000 gallon storage tank is constantly being replenished by this. The center also has a desalinization plant on site, which draws water from the harbor and processes it to meet additional non potable water demands. 10 Natural ventilation and extensive daylighting not only contribute to the building s sustainability goals, but also enhance the user experience. The generous amount of glazing which admits natural light into the space required particular attention in its detailing, especially to ensure its durability. 5

6 RAINFALL & TEMPERATURE AVERAGES 11 Due to year round regular rainfall with a pretty heavy winter season, the existing green roof and related features are able to take care of over 80% of the structure s grey water needs. This includes bathrooms and irrigation for the roof during dry times. The desalinization of sea water on site more than takes care of the remainder. This allows the building as it stands to not need any water from the city under normal circumstances. WATER USAGE/STORAGE 12 With given formula G=[(P)(A)]/(2.15) Average monthly (P) = 3.67 Annual rainfall = Total Precipitation (2/3) = G=[(29.33 )(26,000 ²)] 2.15 G = 354,688 gallons For 212 ged x 365 days = 77,380 gallons Estimated irrigation via sprinklers of 36 with the same formula lends 290,232 gallons 354, ,232 77,380 = 7,076 gallons This total is still below the max capacity of existing cistern so no redesign is required 6

7 BUILDING REDESIGN ENVIRONMENTAL IMPACT 13 With the specific location of this site on a main channel/harbor, and at the edge of a major city, there are unique opportunities to take advantage of with wind and water currents. This facility could generate electricity with the flow of the water features already associated with it. If either this or buffeting coastal winds from the high rises adjacent to the site were used to store power during hours not busy it could potentially take the building off the grid due to the intermittent full usage of space. BUILDING REDESIGN Fixtures 14 The existing toilets in this facility are called out as low flow fixtures. However if the urinals were replaced with water free installations then that would cut down on the already low water usage of the site as well as diminish maintenance costs. 7

8 CONCLUSION An Example of a Sustainable Future It is fitting that the Convention Centre West should have a role to play in the 2010 Winter Olympics, because just as the Olympic games traditionally serve as a reminder of the collective goals of humanity, a beautiful structure that is built in a sustainable, forward looking way can also serve as a reminder of our collective goals. And after its moment in the international spotlight has passed, this convention center will continue to exemplify the direction of the future by demonstrating that, even in the midst of a crowded city, a building can provide not just for the various needs of the human community, but for the needs of the ecological community as well. 15 QUESTIONS? 8
