Methodology for the accounting, generation, and composition of building-related construction and demolition (C&D) at a regional level was explored. Six specific categories of debris were examined: residential construction, nonresidential construction, residential demolition, nonresidential demolition, residential renovation, and nonresidential renovation. Debris produced from each activity was calculated as the product of the total area of activity and waste generated per unit area of activity. Similarly, composition was estimated as the product of the total area of activity and the amount of each waste component generated per unit area. The area of activity was calculated using statistical data, and individual site studies were used to assess the average amount of waste generated per unit area. The application of the methodology was illustrated using Florida, US approximately 3,750,000 metric tons of building-related C&D debris were estimated as generated in Florida in 2000. Of that amount, concrete represented 56%, wood 13%, drywall 11%, miscellaneous debris 8%, asphalt roofing materials 7%, metal 3%, cardboard 1%, and plastic 1%. This model differs from others because it accommodates regional construction styles and available data. The resulting generation amount per capita is less than the US estimate - attributable to the high construction, low demolition activity seen in Florida.
探讨了区域层面与建筑相关的建筑和拆除（C&D）的核算、产生及构成方法。研究了六种特定类型的废弃物：住宅建筑、非住宅建筑、住宅拆除、非住宅拆除、住宅翻新和非住宅翻新。每项活动产生的废弃物量通过活动总面积与单位活动面积产生的废弃物量相乘计算得出。同样，构成比例通过活动总面积与单位面积产生的每种废弃物成分量相乘估算得出。活动面积使用统计数据计算，通过个别场地研究评估单位面积产生的平均废弃物量。以美国佛罗里达州为例说明了该方法的应用。2000年，佛罗里达州估计产生了约375万公吨与建筑相关的C&D废弃物。其中，混凝土占56%，木材占13%，石膏板占11%，杂物占8%，沥青屋顶材料占7%，金属占3%，纸板占1%，塑料占1%。该模型与其他模型不同，因为它考虑了区域建筑风格和可用数据。人均产生量低于美国的估计值，这归因于佛罗里达州建设量大、拆除活动少的情况。
