Water Efficiency (L/person/day) quantifies the average daily water consumption per occupant in a property or development, measured in litres. In property development finance UK, assessing water efficiency supports environmental, social and governance (ESG) objectives, helping developers minimise operational costs, comply with regulations, and enhance sustainability credentials. High water efficiency indicates lower consumption and reduced environmental impact, while poor efficiency may increase utility costs and regulatory risk. This metric is critical for financing decisions, design planning, and demonstrating sustainable performance, particularly in commercial and residential developments prioritising responsible resource management and long-term operational efficiency.
This sits beneath Environmental Performance, introducing a more specific variant of the measure without changing its core interpretation. It is commonly considered alongside Water Efficiency Rating, as both are closely related measures used to assess similar aspects of performance or risk.
