This short communication reports on the implementation and validation of the three-phase method for daylight calculations in the freely available software DIALux evo. Compared to the previous approach to daylight calculation in DIALux, the 3-phase method allows for a faster calculation of yearly daylight illuminance without sacrificing accuracy. DIALux is one of the most widespread software among electric lighting designers. By implementing simple, accurate, and fast analysis, this new version of DIALux makes daylight analysis easily available to electric lighting designers. This can unleash the potential of properly integrated daylighting and electric lighting design, for better and more efficient lighting projects.

这份简短的通讯报告了在免费软件 DIALux evo 中进行日光计算的三相法的实施和验证。与之前在 DIALux 中计算日光的方法相比，三相法可以在不牺牲准确性的情况下更快地计算每年的日光照度。DIALux 是电灯设计师使用最广泛的软件之一。通过实施简单、准确和快速的分析，这个新版本的 DIALux 使电灯设计师可以轻松地进行日光分析。这可以释放适当集成采光和电气照明设计的潜力，以实现更好、更高效的照明项目。
