Taikoo Hui’s Landscaped Plazas and Green Roofs form a peaceful, yet dramatic public park on a plateau, removing the car from the outdoor experience. This 4.44 million SF Mixed-Use Development project in Guangzhou, China, contains a bank, office and hotel/residential towers, cultural center, retail mall, green roof and at-grade plazas, on only 12.1 acres. The highly choreographed development improves economic sustainability for the developer, allowing a very dense mix of uses due to the creative maximization of landscaped open space on multiple levels. The roof gardens and street level plazas provide a highly aesthetic, restorative amenity for users of the complex, and the community at large.
Over 2.5 acres of multi-level intensive green roof and landscaped plazas over the retail mall functionally and visually link the elements, and provide a public park, dining/gathering areas, and pool/spa areas. A wave-like glass atrium allows shafts of natural sunlight to penetrate four levels of mall below. Nearly 3 acres of street-level landscape ties the development to its surroundings, underground train station, parking and service areas, while decorative atrium and vent perforations bring light and air below ground.
The intensive green roof, with soil to 6.5 feet deep, supports large trees and dense native plantings, providing more significant environmental services than traditional extensive green roofs, including greater air filtering and carbon storage, and greater cooling effect to the cityscape. The green roof and high albedo, locally available concrete pavers insulate the mall, extending the life of the building, and reducing energy use and contributions to urban heat island effect. Plant material and engineered soils were locally sourced. The green roof planting beds improve stormwater management, and reduce required irrigation, allowing only minimal hand watering in order to support plants selected and grouped for their adaptability to the site conditions, climate and design intent.
