Park 20/20: A Cradle to Cradle Inspired Master Plan

    Park 20/20 is a new business park and retail center located on land reclaimed from the sea called a “polder.” Built since the 11th century, polders are man-made landscapes that require the construction of dikes or sea walls to prevent the land from flooding during high tide. These areas are challenged by limited biodiversity and rising sea levels.

    To restore the site’s biodiversity and address the challenges presented by polders, Park 20/20 incorporated sustainable design practices into all aspects of development from its transit-oriented layout to its careful stewardship of the environment. The plan is guided by the regenerative, waste-free “Cradle to Cradle” design philosophy introduced by William McDonough.

    Park 20/20’s polder land was previously used for agricultural purposes, which meant that only a few crops dominated the landscape. The new master plan helps restore the native ecosystem by creating interconnected green spaces in the form of community gardens, street plantings, and green roofs. These areas include native vegetation and effectively rejoin the landscape with a larger system of existing parks and wildlife habitats.

    To create a diverse cultural and economic community within a once-uniform landscape, Park 20/20 uses a mixed-use development approach to combine office space with restaurants, hotels, and a conference center. The layout also incorporates athletic facilities, daycare, a supermarket, and retail stores that not only help it attract a variety of people, but also make it an attractive and exciting work environment.

    Park 20/20 is strategically located within a 5-10 minute walk of two existing bus and rail stations. A network of sidewalks, garden paths, and canal boardwalks connects the center with the transit stations, providing safe and convenient access to the greater Amsterdam region.

    At its core, Park 20/20 uses a “closed loop” water-management system to treat and reuse wastewater. To accomplish this, building wastewater is directed to a central treatment facility where it is purified and then re-circulated to buildings for use in toilet flushing. Heat generated in the process is used to create hot water for the area’s hotel.

    In order to conserve energy, the designers determined the optimum building orientation by mapping the sun’s path throughout the day and year. This enabled them to angle buildings in a direction that maximized sun exposure during winter and shade during summer.

    Green roofs equipped with photovoltaic (PV) arrays provide the community with a renewable carbon-free energy source. Green roofs provide additional environmental benefits by absorbing and filtering stormwater runoff, increasing biodiversity, and reducing surface temperatures.
