Most people find the idea of a garden or lawn on a 15-storey building quite unusual. Now imagine a grassy playing field, 15-storeys up on the deck of an ocean-going cruise-ship. That is exactly what this year’s Special Recognition award winner is: at 122,000 tons and 1,033 feet long, the Celebrity Solstice is a recent addition to the Celebrity Cruises fleet with an important difference: an authentic 15,000-square-foot grass green roof that covers one-quarter of the uppermost deck of the ship. The Lawn Club provides the perfect venue for guests to enjoy bocce, croquet, a picnic with wine and cheese or a round of golf – all while cruising on the ocean.
Testing was performed in Miami and Germany, as well as on a cruise ship, with various grass types leading to the development of a daunting list of requirements including: a layer set-up that could support Arctic, Northern Europe, Mediterranean and tropical weather conditions; wind resistance for wind speeds 100 mph and wind gusts over 120 miles per hour; a system stable enough to withstand sliding (the ship tilts up to 12° or 27 percent); and vegetation that could be highly salt tolerant and a maximum weight of 130 metric tons for a 15,000-square-foot green roof. Finally, as the ship’s “Lawn Club,” this green roof required that the chosen vegetation be prime turf grass to support activities such as bocce, croquet and golf-putting.
