新时期超大城市绿色建筑发展专项规划编制探索OA北大核心CHSSCDCSTPCD

Buildings and construction are primary fields contributing to carbon emissions.Accelerating energy conservation and carbon reduction in the construction sector is of great significance to achieve carbon peaking and carbon neutrality,as well as promoting high-quality developments.Traditional construction methods with high resource consumption and pollution emissions are unsustainable,especially in densely populated mega-cities where annual construction volumes increase significantly,bearing the heavy responsibility of realizing carbon peaking and carbon neutrality in the construction sector.Green buildings are a natural choice for the comprehensive promotion of green,low-carbon,and high-quality developments in the field of construction. Since the introduction of the green building concept in China in the 1990s,the development of green buildings has gradually shifted from individual projects to regional clusters.In the past,research on green buildings in China mainly focused on green building technology and design,with relatively less attention on green buildings in view of urban planning and layouts.This restricts the application of green buildings more extensively.In the new development period,the development of green building special planning is an important part of the"five-level and three-category"national spatial planning system,and has become a crucial means to strengthen the positioning,control,and guidance of green building spaces,thus promoting the cluster development of green buildings. Green building planning starts late in China.The green building planning process in China was reviewed systematically and it can be divided into three stages:the starting stage of blueprint-oriented development planning,the initial stage of spatial layout planning research,and the transforming stage of exploration under the national spatial planning system.Through the continuous exploration in some Chinese cities,green building special planning has achieved some results.However,there are still challenges in decomposing and implementing planning targets,responding to core requirements,and planning delivery.To address these challenges,it is important to clarify key points of development of green building special planning.1)Strengthen the decomposition and implementation of core indexes for green building planning.2)Enhance the spatial support and control for the development of green buildings.3)Improve the transmission and connection mechanisms between overall national territorial spatial planning and detailed planning. Based on these principles,a case study based on a special plan project for green building development in Guangzhou was conducted.The decomposition and implementation of green building indexes,spatial support and control,planning transmission and connection under the national spatial planning system in mega-cities were discussed.This provides ideas and references for the formulation of special plans for green building developments in other cities.With the goals of becoming an advanced benchmark city for green building development,a leading demonstration city for carbon neutrality in the Greater Bay Area,and a human-oriented green city with Lingnan characteristics,a technical framework for the development of Guangzhou's green building special plan was constructed according to the technical route of"target indexes-spatial response-transmission connection".This framework proposes:1)strategic leadership to construct an index system for green building development that connects carbon goals;2)in-depth control to refine the zoning control guidelines for green buildings;3)coordinated transmission to improve the planning delivery and connection paths oriented towards implementation.
