WTC ten years on: World Trade Center Memorial opens today

The World Trade Center Memorial featuring two giant reflecting pools built within the footprints of the original Twin Towers opens to the public today.

The Memorial was officially opened yesterday by US President Obama and former President Bush during a ceremony marking the 10 year anniversary of the 9/11 terrorist attacks.

Half of the 6.5ha Ground Zero site is dedicated to the World Trade Center Memorial and Museum. Designed by architects Michael Arad and Peter Walker, 400 trees fill most of the plaza and the Memorial Pools have 9m high cascading waterfalls. Consultant was WSP Cantor Seiniuk and Bovis Lend Lease built it.

The Memorial’s plaza has been created as one of the most sustainable, green plazas ever constructed. Its irrigation, storm water and pest management systems will conserve energy, water and other resources. Rainwater will be collected in storage tanks below the plaza surface. A majority of the daily and monthly irrigation requirements will be met by the harvested water.

The project is pursuing the Gold certification in the US Green Building Council’s LEED for New Construction programme. LEED is a third party certification programme for green building, design and construction. The plaza is also built to meet requirements of New York State Executive Order 11 and the WTC Sustainable Design Guidelines, which both promote environment-friendly practices.
