Meixihu International New City Eco-city

20 1 2165438+1October1Yi Xiaolin, director of the Urban and Rural Planning Division of the Housing and Construction Department of Hunan Province, revealed at the relevant meeting that the Implementation Plan for Meixihu New Town to Apply for National Low-carbon Ecological Pilot City has been issued and is being submitted to the Ministry of Housing and Urban-Rural Development for approval. If successfully approved, Meixihu New Town will become the first national low-carbon ecological pilot city in Hunan. The city's industrial development adheres to high-end development and cultivates and expands "two-oriented" industrial clusters. Efforts will be made to promote the construction of national innovative science and technology parks in high-tech zones and form high-end industrial clusters. At the same time, relying on Meixi Lake area, we will vigorously develop high-end service industries such as R&D, finance, commerce and trade, exhibitions and tourism.

Meixihu New Town will rely on high-tech industries (electronic information, advanced manufacturing, new materials, new energy and energy conservation and environmental protection, bio-pharmaceuticals, advanced manufacturing, creative design, etc.), neighboring cities, human resources (Central South University, Hunan University, Changsha University of Science and Technology, etc. ), government support (government leading industry positioning and base construction standards, integrating resources such as developers, enterprises and talents, and the construction and development model of government-enterprise cooperation) and other resources to develop the new city service industry.

According to the experience of calculating jobs in most CBD at home and abroad, the average number of jobs is 25-30 square meters, and the total area of public buildings in Meixihu New Town is 3,276,700 square meters. According to the average employment of 27.5 square meters, the number of jobs that Meixihu New Town can provide is about 1 19200, and the total population of Meixihu New Town is 18. Peng Xin Mine revealed that there are seven schools in Meixihu New Town, all of which are planned and built according to the green school. The supporting primary school of the indemnificatory residential community in Meixi Lake District ("Yuelu Experimental Primary School") is the first batch of green building pilot projects in Changsha, 20 1 1, which has been put into use since April of 20 12.

The hardware construction of green campus includes green classroom, green restaurant, green campus and monitoring display platform. The establishment of green education includes green laboratory, green teaching research, extracurricular activities and students' influence on parents. By cultivating students' ideas of energy conservation, environmental protection and green harmony, families are further influenced, and families drive society to advocate environmental protection.

According to Changsha Renewable Energy Assessment Report, Changsha belongs to four types of solar energy resources. It is more suitable to use solar energy to make domestic hot water. Peng Xinguang revealed that public buildings in Meixihu New Town plan to use shallow geothermal energy, and residential buildings plan to use solar hot water.

So how to supervise the energy consumption after the building is completed? Peng Xin Mine introduced that new public buildings in the planning area should independently measure the energy consumption of cold and heat sources, transmission and distribution systems and lighting systems, install sub-metering devices and connect with the urban energy consumption statistics data center.

The main energy consumption links such as cold and heat sources, power transmission and distribution system, lighting, office equipment and hot water consumption in the building are separately measured, and the property is recorded regularly. Sub-metering shall meet the requirements of Technical Guide for Design and Installation of Sub-metering System for National Office Buildings and Large Public Buildings. Public buildings with central air conditioning system should be equipped with cooling and heating metering devices according to floors, indoor areas, users or rooms; The cold and heat source stations of public buildings and their complexes should be equipped with cold and heat metering devices. Meixihu New Town adheres to the principle of sustainable development, and the planning and design of Meixihu New Town is based on the following principles: reducing carbon emissions caused by internal traffic through a compact and convenient walking mixed society; Provide full employment opportunities through self-sufficient urban centers; Create a traffic hierarchy based on zero carbon and low carbon through the green traffic system; Adopt passive design to reduce carbon emissions; By integrating the green water system, the microclimate in urban areas can be improved, a comfortable environment can be provided and the urban heat island effect can be reduced.

Combined with the planning scale of Meixihu New Town and the characteristics of residential buildings as the main body, the index system adopts carbon emission control and parallel planning index system, which makes the index value reach the domestic advanced level, while diluting the index requirements of "economic sustainability" and strengthening the construction of "resource conservation" and "environmental friendliness". The whole index system includes 45 special indicators, of which 20 are control indicators and 25 are guidance indicators. The whole index system involves nine aspects: urban planning, architectural planning, energy planning, water resources planning, ecological environment planning, transportation planning, solid waste planning and green humanity. After sufficient feasibility analysis and demonstration, scientifically determine the index values, and implement key indicators for research projects to ensure the feasibility and feasibility of indicators.
