一个商业计算机辅助设计工具使用的照明工业进行了修改，以预测注量率为上室紫外线杀菌照射。实验验证的基础上超过1600测量和3种类型的商业紫外线灯具，这是在实验室和无家可归者收容所连续使用超过7年的夹具，显示测量和预测的平均上层房间的注量率小于10%的差异。然而，计算机辅助设计工具，是不是很成功的预测在特定的房间位置的注量率，一种能力，需要配合计算流体动力学与紫外线杀菌照射。虽然不是本研究的目的，但也发现本研究中使用的三种类型的灯具在基于灯具紫外线功率输出和电输入的效率上具有令人惊讶的显著差异。一种灯具的效率是另一种灯具的五倍以上。为了便于比较，需要一种测量和报告夹具效率的标准方法。
A commercial computer-aided design tool used by the lighting industry was modified to predict fluence rates for upper-room ultraviolet germicidal irradiation. Experimental validation based on more than 1600 measurements and 3 types of commercial ultraviolet fixtures, which was done in an experimental chamber and in a homeless shelter having fixtures in continuous use for over 7 years, showed differences in measured and predicted average upper-room fluence rates of less than 10%. The computer-aided design tool, however, was not very successful at predicting fluence rates at specific room locations, a capability that is needed for mating computational fluid dynamics with ultraviolet germicidal irradiation. Although not an objective of this study, it was also found that the three types of fixtures used in this study have surprisingly significant differences in efficiency based on fixture ultraviolet power output and electrical input. One fixture type had an efficiency that was more than five times that of another. For comparison purposes, a standard method for measuring and reporting fixture efficiency is needed.
