Abstract Currently, policy makers in Sweden are considering updating building regulations with respect to daylight provision. Given this context, the present paper aims to provide insight on the level of compliance of residential spaces when tested against five daylight performance criteria. These included the criterion currently in force in Sweden, the two performance criteria set by European Standard EN17037, a daylight factor-based criterion (BREEAM) and a climate-based criterion founded on the UDI metric. Compliance was tested by performing Radiance simulations on a representative sample of Swedish multi-dwelling buildings, including 10888 rooms. The criteria were compared according to the compliance they yield for different buildings and room types. Compliance per criterion was also associated with room geometry to evaluate which geometric measures affect it most substantially, and with urban density to evaluate which criterion best captures the effect of surrounding obstructions. Results indicate that the implementation of different criteria deem different building types to be better or worse performing. A consistent finding is that the vast majority of evaluated spaces are deemed to be incompliant when tested against the daylight-factor-based criterion of EN17037, which is significantly harder to comply with compared to its climate-based counterpart. The highest compliance is achieved when testing against the current Swedish criterion. The results also indicate that the Vertical Sky Component and glass-to-floor ratio affect compliance most substantially compared to other geometric measures. Finally, when daylight compliance was associated with urban density, the strongest association was acquired when rooms were tested using the UDI criterion.

住宅空间的日光合规性：不同性能标准的比较以及与房间几何形状和城市密度的关联

摘要 目前，瑞典的政策制定者正在考虑更新有关日光供应的建筑法规。鉴于这种情况，本文旨在提供对居住空间在根据五个日光性能标准进行测试时的合规性水平的见解。其中包括目前在瑞典生效的标准、欧洲标准 EN17037 设定的两项性能标准、基于日光因素的标准 (BREEAM) 和基于 UDI 指标的基于气候的标准。通过对瑞典多住宅建筑的代表性样本（包括 10888 个房间）执行 Radiance 模拟来测试合规性。这些标准根据它们对不同建筑物和房间类型的合规性进行了比较。每个标准的合规性还与房间几何形状相关联，以评估哪些几何措施对其影响最大，并与城市密度相关联，以评估哪个标准最能捕捉周围障碍物的影响。结果表明，不同标准的实施会认为不同的建筑类型表现更好或更差。一致的发现是，根据 EN17037 的基于日光因素的标准进行测试时，绝大多数评估空间被认为不合规，与基于气候的对应标准相比，该标准明显更难遵守。根据当前的瑞典标准进行测试时，可达到最高的合规性。结果还表明，与其他几何测量相比，垂直天空分量和玻璃与地板的比率对顺应性的影响最大。
