摘要

减少建筑部门的能源使用对于创建可持续城市和减缓全球变暖至关重要。城市建筑能源模型（UBEM）是评价区域能源需求和改造潜力的有效方法。本文介绍了一种基于原型的UBEM校准方法，以评估能源数据和建筑相关数据细节的不同时间尺度对多住宅建筑能源性能的影响。在瑞典北部的一个案例区被用来确定在地区范围内各种翻新战略的影响。通过对比区域模型与高分辨率能量数据的性能，验证了基于原型的标定方法的适用性。使用月分辨率数据校准基于原型的模型显示了与使用更高分辨率数据相似的结果。此外，具有较少原型的区域模型可以减少建模时间和复杂性，同时与具有更高细节的更多原型组成的模型相似。结果表明，对UBEM的简化可以在不影响性能精度的情况下使用，并且可能有助于在数据限制的情况下进行区域建模。本研究的结果有助于了解现有地区的超边界管理和能源效率措施对地区能源绩效的影响。

Archetypes-based calibration for urban building energy modelling

Reducing energy use within the building sector is vital to create sustainable cities and mitigate global warming. Urban building energy modelling (UBEM) is useful to evaluate energy demand and renovation potential in districts. In this paper, an archetypes-based calibration approach for UBEM is introduced to evaluate the effect of various timescales for energy data and detail of building-related data on the energy performance of multi-residential buildings. A case district in northern Sweden was used to identify the impact of various refurbishment strategies at district-scale.

The applicability of the archetypes-based calibration approach was validated by comparing the district model performance with high-resolution energy data. Calibrating the archetypes-based model with monthly resolution data showed a similar outcome as using higher-resolution data. Further, a district model with less archetypes can reduce modelling time and complexity, while performing similarly as a model consisting of more archetypes with higher detail. The results suggest that simplifications to UBEM can be used without compromising the performance accuracy and might facilitate district modelling in situations with data limitations.

The findings in this study contribute to the knowledge on UBEM of existing districts and energy efficiency measures’ impact on district-level energy performance.
