2014年秋天，丹麦政府提出了建筑行业的国家战略。可持续性被认为是该部门未来政治工作的五个重点领域之一。随后，启动了国家建筑物生命周期评估工具的开发，并于2015年推出了第一版LCAbyg。LCAbyg开发的主要目标是通过对LCA结果进行明智、直观和透明的可视化，提高建筑设计师对建筑物生命周期影响的认识，并了解在建筑生命周期中可以减少环境影响的地方。本文介绍了LCA工具的原理，包括建筑评估所需的输入数据、模型中的计算方法以及如何将LCA结果呈现给用户。本文还演示了该工具如何使用户能够对不同的施工解决方案和材料使用进行比较，并详细说明了预定义的结果可视化如何使设计师有资格识别热点，并了解和减轻整个建筑生命周期的主要影响。
In the autumn of 2014, the Danish government presented a national strategy for the building sector. Sustainability was mentioned as one of five focus areas for the future political work within the sector. Subsequently, the development of a national Life Cycle Assessment tool for buildings was initiated, and the first version of LCAbyg was launched in 2015. The primary goal behind the development of LCAbyg has been, with judicious, intuitive and transparent visualization of LCA results, to increase building designer’s awareness of the life cycle impacts of buildings, and to understand where, in the building life cycle, reductions of environmental impacts can be achieved. This paper describes the principles of the LCA tool in terms of the required input data for the building assessment, the calculation methods within the model and how the LCA results are presented to the user. The paper furthermore demonstrates how the tool enables the user to perform comparisons of different construction solutions and material uses, and elaborates on how the predefined visualization of results qualifies the designer to identify hotspots and to understand and mitigate the major impacts throughout the building’s life cycle.
