It was reported that a study conducted by Associate Professor Alberto Salvo from the Department of Economics at NUS Faculty of Arts and Social Sciences has found that lower-income households tend to use more water when the weather is hot, while higher-income households consume more electricity. The study tracked the water and electricity bills of about 130,000 households living in apartments from September 2012 to December 2015.

It can also facilitate better design and allocation of water and electricity grids.
