As part of the project for the Expo Cultural Park in Shanghai, DMAA won a competition for the realisation of a series of greenhouses that are being built on the city’s former Expo site. The decision of the city authorities to transform such a large, centrally-located reserve of land into a high-quality recreational zone offers clear proof of the global trend towards the more intensive greening of core urban areas. One of the conditions of the competition was the retention of a former factory building that is used, in DMAA’s proposal, as a distribution zone for the complex, which contains greenhouses with a range of different vegetations and climates, a visitors’ centre and numerous restaurants and other spaces for relaxation with a total usable area of 41,000m2.
The principle of dual energies that is set out in the Chinese philosophy of “Yin and Yang” was the starting point for the architectural approach. This establishes a dialogue between the modular and linear structure of the existing factory hall and the sculptural articulation of the individual, organic, 15-to-22-metre high greenhouses, which are woven into this existing structure, and whose roofs are perforated with a series of large circular openings.
该设计是为了满足零能耗建筑的严格生态要求而构思的，也反映在该建筑群与周围景观公园的温和和谐的插入上。温室周围的大片水域不仅在炎热的夏季提供冷却，而且也是一个太阳能电站的所在地，该电站位于水面以下几厘米处，与现有厂房屋顶上的额外面板一起，提供控制各种气候区所需的能源。能源概念是与Transsolar Energietechnik公司的总经理Thomas Auer共同开发的，其基础是决定用单层玻璃为温室上釉，以尽量减少对日光的过滤。亭子屋顶上的巨大开口也确保了植物获得足够的日光。
The design, which was conceived to meet the exacting ecological requirements of a zero-energy building, is also reflected in the gentle and harmonic insertion of the complex into the surrounding landscape park. The large area of water surrounding the greenhouses not only provides cooling in the hot summer months, but is also home to a photovoltaic plant that is located just a few centimetres below the surface of the water and, together with additional panels on the roof of the existing factory building, supplies the energy required to control the various climatic areas. The energy concept, which was developed together with Thomas Auer, Managing Director of Transsolar Energietechnik, is based on the decision to glaze the greenhouses with a single layer of glass in order to minimise the filtering of the daylight. The generous openings in the roofs of the pavilions also ensure that the plants receive enough daylight.
The spatially orchestrated vegetation scenarios lead visitors from the ravines and sand dunes of the desert pavilion, via the swamps and waterfalls of the tropical rainforest and the terraced landscapes of the so-called cloud garden, to the opulent blossoming of the towers of flowers. The tour is completed by the opportunity to visit the terrace on the roof of the existing factory building, from where visitors can take in the entire park and, beyond this, the built edge of the surrounding city.
