Distinguishing between indoor use and outdoor use is becoming increasingly important, especially in water-scarce regions, since outdoor use is typically targeted during water restrictions. Household water use is typically measured at a single water meter, and the resolution of the metered data is typically too coarse to employ on commercially available disaggregation software, such as flow trace analysis. This study is the first to classify end-use events from a rudimentary data set, into indoor use or outdoor use. This case study was conducted in Johannesburg, South Africa, and quantified the volume of water used indoors and outdoors at 63 residential properties over 217 days. A recently developed model for classifying water use events as either indoor or outdoor, based on rudimentary water meter data, was employed in this study. A total of 212,060 single end-use events were classified as being either indoor or outdoor. The indoor and outdoor consumptions were compared with survey results. It was found that 30% of all events were outdoor, based on the total volume.

根据基本数据集将家庭用水分为室内和室外用途:南非约翰内斯堡的案例研究

区分室内使用和室外使用变得越来越重要,尤其是在缺水地区,因为室外使用通常是在限制用水期间进行的。家用用水通常是在单个水表上测量的,而计量数据的分辨率通常过于粗糙,以至于无法在可商购的分类软件(例如流量跟踪分析)上使用。这项研究是首次将来自原始数据集的最终使用事件分类为室内使用还是室外使用。该案例研究是在南非约翰内斯堡进行的,对217天中63处住宅物业的室内和室外用水量进行了量化。在这项研究中,采用了一个最新开发的模型,该模型基于基本的水表数据将室内或室外的用水事件分类。总共212 060个最终用途事件被分类为室内还是室外。将室内和室外的消费与调查结果进行了比较。根据总数量,发现所有事件中有30%是户外活动。
