Vancouver's Olympic and Paralympic Village was home to 2800 athletes and officials at the 21st Winter Olympic Games. Its specifications required reducing the buildings' environmental footprint in terms of energy efficiency, water consumption, heating, use of local materials, and reuse of any surplus. Several formulations of high-volume fly ash concrete helped meet the cost, performance, and sustainability requirements. With eight complexes distributed over a 90-acre waterfront property, the 600,000-square-foot village contains more than 600 dwelling units. After the Paralympic Games, the environmentally friendly village became Millennium Water, a community that will be home to 16,000 people. Plans call for 250 housing units, a 45,000-square-foot community center, an elementary school, community garden, and much more. Now hailed as the greenest neighborhood in the world, Millennium Water has received international recognition for reducing resource use, minimizing its carbon footprint, and showing new possibilities for urban planning.
