Caofeidian International EcoCity
A new ecological city in the Tangshan region 250 kilometres East of Beijing. About 1-1.5 million people are expected to live in the city in a long term perspective. The project is supported by both Chinese and Swedish government and especially leaders at the ministries and Hebei provincial government. With the close involvement of Tangshan municipal government, the Swedish Embassy and CENTEC, Caofeidian New District and Caofeidian Eco-City, with the contribution of Chinese consultants, and with the innovative hard work of Sweco’s team, a concrete plan of the Eco-City aiming at a world leading class was born. Sweco has performed overall conceptual planning as well as landscape design and building design. The new EcoCity will have an area of 150 square kilometres with a first development phase of 30 square kilometres. A major deep harbour and an industrial area is also planned in connection to the city. The goal of the project is to build a both climate neutral and attractive city, mainly based on a combination and adaptation of Swedish innovative examples on different planning levels. Sweco is also designing a Sustainability Centre including exhibitions of sustainable development ideas and city development, training, facilities, R&D and interactive demonstration equipment for environmental technology. Caofeidian’s Eco-Cycle Model proposes an integrated management of water, energy, waste and materials. The plan strives to reduce greenhouse gas emissions, manage fresh water in a sustainable way, and increase recycling/recovery by connecting water, energy and waste systems. Connected closed loop systems for industrial, agricultural and urban areas are also envisioned. A medium and long term economic benefit is expected especially due to the effective resource and energy recovery. The climate-neutral energy systems are based on achieving the lowest possible energy demand through construction of energy-efficient buildings and systems. Local renewable power production is based mainly on windmills and waste incineration, with the option of increasing other renewable energy sources such as solar cells and tidal energy. The resources management centre (RMC) is a demonstration area for the Eco-Cycle Model and functions as the “heart` of Caofeidian’s infrastructure, supplying its public utilities through various treatment plants. These plants are organized and linked to improve resource recovery efficiency. The recommended location for the RMC is north of the new freshwater channel in the transition zone between Caofeidian and the surrounding agricultural fields. The EcoCity has a compact and varied mixed-use structure. Different city structures are interwoven to create an inspiring whole. The urban nodes serve as centres for the city-districts and should be given distinct urban profiles such as innovation, trade, science and sports. The structure supports the development of sustainable transportation modes with priority for walking, bicycling and public transportation. The green and blue structure is an integral part of the public space. Density varies across the Eco-City, with a certain degree of compactness as an overall feature. Mixed-use is a major feature, and is expressed as a combination of housing, workplaces and services. A wide range of urban districts with different characters are interwoven across the city to create an appealing mix. Each district is served by a mixed-use node, themselves conceived of as distinct areas, each with its own identity. The city has a general structure that allows rapid or slow expansion but also different ways of varying the subdivision and urban design of individual blocks. The overall orthogonal structure of the EcoCity offers a basis for an infinite variety of urban design and architectural achievements. This integrated urban structure contributes to quality of life, liveability, social security, inclusion and health.
