Three climates greenhouse
The Hortus Botanicus Amsterdam is one of the oldest botanic gardens in the world. Today, there are more than 6,000 plants (>4,000 species) growing in the garden and greenhouses.
The eye-catcher is the ultramodern construction of the three-climate greenhouse designed by Zwarts and Jansma. The greenhouse is subdivided into 3 zones for different types of climates: a tropical, a subtropical and a desert climate, separated by glass walls. A computer system automatically controls the temperature and humidity in the 3 different areas. To reduce costs, the façade was made with mass-production greenhouse components. The main load-bearing structure was designed as slender as possible for optimum daylight in the greenhouse. High up in the glasshouse there is a steel walkway with a glazed floor, offering a view of the treetops. The bridge structure consists of a round tube, which also supports the handrails and the supports for the glass floor.
