Benefits of the scheme

​Research into the benefits of ​the Water Efficiency Labelling and Standards (WELS) scheme was conducted by the Institute for Sustainable Futures at the University of Technology Sydney in 2015.

This research focused on both the financial savings and environmental benefits delivered by the scheme. The results were detailed in a full report, with an addendum for additional analysis on the potential impacts of a proposed new showerhead rating.

E​valuation o​f the Environmental Effects of the WELS Scheme​

Publication details

Fyfe, J, McKibbin, J, Mohr, S, Madden, B, Turner, A & Ege, C for the Department of the Environment, 2015

The Evaluation of the Environmental Effects of the WELS Scheme ​details the outcomes of research in four key areas:

  • Product registration and sales trends — showing a consistent shift and convergence across all product categories toward more efficient products.
  • Reduced water consumption and household expenses — approximately double the reductions that were initially projected.
  • Reduced energy use, greenhouse emissions and household expenses — linked to the reduced water consumption achieved through the WELS scheme.
  • References to WELS in other urban water policies — found in 20 water efficiency programs, 4 energy efficiency programs, 6 building codes, regulations and rating schemes, and 3 tenancy laws.

Addendum — Analysis of the​ Impacts of a Proposed New Showerhead Rating

Publication details

McKibbin, J & Turner, A for the Department of the Environment, 2015

Building on the Evaluation of the Environmental Effects of the WELS Scheme, the Institute for Sustainable Futures was commissioned to estimate the impacts of a new ‘4 star’ rating for efficient showerheads.

Since this additional review was completed, the 4 star rating for efficient showerheads has been added to the WELS scheme.
