Statistical Analysis of Seven Water Efficiency Studies using Control Groups and Weather Influences (2013)
This project by Essex & Suffolk Water was concerned with analysing and reporting the extent to which external factors influence demand during periods when water efficiency studies are undertaken. Seven studies were included in the analysis, both domestic and commercial retrofit schemes. Measured water consumption data were used to calculate the mean pre and post intervention consumption per day at each property. The difference between the pre and post consumption was calculated for each property.
