Masterplanning for Circular Development - Beyond Whole Life Carbon

建筑环境占全球能源消耗的40%，原材料消耗的40%，木材消耗的25%。除了对材料的直接需求外，所有新的住房/工业发展项目都会带来额外的消费模式，以及对供暖、电力和交通的新需求。总体而言，这些需求对全球温室气体排放和生物多样性损失产生了实质性影响。这些问题既不会被未来住房标准(2025年)克服，也不会被全寿命评估所克服，后者都只考虑开发总影响的一个子集(例如，仅考虑运营能源和直接材料)。鉴于气候和生物多样性的紧急情况，许多开发商、利益相关者、地方当局和行业领袖正在寻求创建真正可持续的开发--减少材料使用并利用整个生命周期的再利用和再循环机会的开发。我们的愿景是为建筑环境专业人员指定和开发一种新的循环设计工具。考虑到发展的所有影响(包括交通、人类活动和消费等诱发活动)。这将在设计的最早阶段嵌入循环方法，减少材料使用，并设计出不可持续的消耗，以实现真正的可持续发展。通过在总体规划阶段嵌入循环决策，我们将支持在建筑环境中逐步采用循环经济方法。

The built environment is responsible for 40% of global energy consumption, 40% of raw aggregate consumption and 25% of the world's wood consumption. In addition to direct demand for materials, all new housing/industrial developments induce additional consumption patterns and new demands for heat, electricity and transport. Collectively, these demands have material impacts on global GHG emissions and biodiversity loss.These issues will neither be overcome by the Future Homes Standard(2025), nor Whole Life Assessment, which both consider only a sub-set of the total impacts of the development(e.g. only operational energy and direct materials).Given the climate and biodiversity emergencies, many developers, stakeholders, local authorities and industry leaders are seeking to create developments that are truly sustainable- developments that reduce material use and make use of re-use and re-cycling opportunities across their lifecycles.Our vision is to specify and develop a new circular design tool for built environment professionals, which takes account of all impacts of the development (including induced activities such as transport, human activity and consumption). This will embed circular approaches at the earliest stage of design, reducing materials use and designing-out unsustainable consumption to deliver truly sustainable developments.By embedding circular decision-making within the masterplanning stage, we will support a step-change in the adoption of circular economy approaches within the built environment.
