Park 20|20, a 28-acre office park in Haarlemmermeer, Netherlands, is designed with the health of the building occupants in mind. The project, developed by Delta Development Group and designed by William McDonough + Partners, features specially selected plants that are used to filter internal air through green walls that store carbon dioxide and produce fresh oxygen. Dust is minimized through a ductless floor system and through moss that acts as a natural filter.
Natural light is abundant throughout the office space, minimizing the need for much artificial light. LED lighting—the closest lighting to sunlight—was used to the extent possible, and an automated sun-shading system regulates the interior lighting based on sun and cloud cover. Each office space contains a window that can be opened for fresh air, and buildings are horseshoe shaped with large atriums that allow natural light from two sides. Natural views are provided through 22 acres of open space, which includes a central park that is visible from surrounding streets.
