建筑物的节能改造在实现气候目标方面发挥着重要作用。与单纯的建筑物翻修相比，地区一级的翻修可能有几个好处，例如单位成本较小，因此成本降低。此外，它提供了市政当局更好的机会，实施能源和可持续性strategies.This介绍了一个地区规模的程序，用于分析建筑物的节能改造。开发程序的主要目标是：1）简单的方法来喂养信息，2）动态计算能力，和3）支持决策者。为了支持目标，该程序结合了能量模拟，3D数据建模和可视化。此外，CityGML是用来接收建筑相关的district data.The程序进行了测试，在芬兰的案例区，共6个现实的翻新方案进行了比较，通过运营成本，能源使用和CO2排放。测试分析表明，不同的情景可能会产生相互冲突的影响，为决策者提供重要的信息。该程序不限于演示的场景，但可以根据不同的目的进行修改。此外，还将该手术与文献中确定的其他区级手术进行了比较。该程序被证明是一个有前途的基础上，评估地区规模的能源更新的替代方案。
Energy-efficient renovation of buildings is in a major role in achieving the climate targets. Refurbishment at district scale may contain several benefits compared to mere building renovations, such as reduced costs due to smaller unit costs. Furthermore, it provides municipalities better opportunities to implement energy and sustainability strategies.This paper introduces a district-scale procedure for analyzing energy-efficient refurbishment of buildings. The main targets for the developed procedure were: 1) easy way for feeding information, 2) dynamic calculation capacity, and 3) support for decision makers. In order to support the targets, the procedure combines energy simulation, 3D data modelling and visualization. Additionally, CityGML is utilized to receive building related district data.The procedure was tested in a Finnish case district where altogether six realistic refurbishment scenarios were compared by means of operational costs, energy usages and CO2emissions. The test analyses demonstrates that different scenarios may have conflicting impacts which give important information to the decision-makers. The procedure is not limited to the demonstrated scenarios but it can be modified for different purposes. Additionally, the procedure was compared to other district-level procedures identified from the literature. The procedure turned out to be a promising basis for assessing district-scale energy renovation alternatives.
