A new ecological city in the Tangshan region is being designed, 250 km 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. Sweco has performed overall conceptual planning as well as landscape design and building design.
The new EcoCity will have an area of 150 sq km with a first development phase of 30 sq km. 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.
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 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.
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.
