Abstract：In the context of urban renewal,peak carbon emissions and carbon neutrality,industrial remains shall be reused to achieve the green and low-carbon retrofitting objectives based on historical cultural protection and the improvement of urban functions.Based on field research on industrial remains in Yangtze River Delta,this study pointed out to preserve the site layout based on industry manufacture procedure,and to identify two types of architectural spatial forms and building interface features.The major problems to be solved during reuse include negative relationships between factory site and city,river and greenfield ecosystem pollution,poor outdoor environmental quality,vast architectural spaces and excessively isolated buildings with enclosed interfaces.Referring to material and operational carbon reduction approaches and climate adaptability principles,the general framework for progressive green and low-carbon reconstruction and reuse design of industrial buildings should follow the positive design process and three basic levels of architectural spatial form.This framework consists of five aspects:analyzing site conditions to use local resources effectively,optimizing site layout to improve micro-climate,adjusting architectural spaces for better energy management,updating building interface to regulate energy exchange,and promoting multi-disciplinary collaboration for integrated design.Subsequently,ten design strategies which can reflect correlations between characteristics of industrial remains,green and low-carbon objectives and architectural design techniques were further elaborated by combining case study with and design practices in Yangtze River Delta.Design operations of two types of architectural spatial forms on large,medium and small scales were illustrated by diagrams.These ten key strategies and techniques are introduced as follows:solutions for climate(hot summer and cold winter)responsive architecture and analysis on urban ecological systems of the industrial site;reserving and reusing valuable industrial buildings to maximum extent based on comprehensive assessments;repairing river ecological corridors and establish rain water management systems;optimizing the thermal environment by transferring high-density industrial building clusters reasonably;building expansion and flexible spatial system based on modular dimensions of industrial remains;controlling building volume and general energy consumption,dividing vast spaces into human-scale spaces and lowering energy consumption of space units;expanding diverse transitional spaces with low energy consumption and guiding outdoor activities;improving transparency and thermal performances of industrial interfaces to increase spatial comfort;greening large roofs of industrial buildings to form thermal insulation interface and to improve scenery;supplying energy sources for the park through solar energy facilities on large roof surfaces of industrial buildings.
