English Definition

The strategic reduction of water consumption in buildings through efficient fixtures, systems, and practices โ€” a critical sustainability priority in the UAE, which has one of the world’s highest per capita water consumption rates and relies almost entirely on energy-intensive desalination for its potable water supply.

The Water Challenge in the UAE

Water efficiency in buildings refers to the use of less water to achieve the same functional outcomes โ€” through fixture selection, system design, operational practices, and water reuse strategies. In the UAE, water efficiency carries exceptional strategic importance. The country receives an average annual rainfall of less than 100mm, has negligible natural freshwater resources, and relies on energy-intensive seawater desalination for approximately 99% of its potable water supply. UAE residents consume an average of 550 litres per person per day โ€” among the highest per capita water consumption rates in the world, compared to a global average of approximately 170 litres per day.

The energy cost of desalination links water consumption directly to carbon emissions: producing one cubic metre of desalinated water in the UAE consumes approximately 3โ€“5 kWh of electricity. This means that reducing water consumption in buildings simultaneously reduces energy demand, carbon emissions, and the strain on the country’s strategic water infrastructure โ€” making water efficiency a dual environmental and national security priority.

Water Efficiency Measures in UAE Buildings

A comprehensive water efficiency strategy for UAE buildings addresses consumption across all end uses. Sanitary fixtures โ€” toilets, urinals, basin taps, and showers โ€” account for the largest share of indoor water use in commercial and residential buildings; specifying low-flow or dual-flush WCs, low-flow basin taps, and efficient showerheads can reduce fixture water consumption by 30โ€“50% compared to standard products. HVAC condensate recovery โ€” collecting the condensate water produced by air conditioning cooling coils, which can amount to several litres per kW of cooling capacity per day in the UAE’s humid climate โ€” provides a significant source of non-potable water for irrigation or cooling tower makeup. Greywater recycling treats wastewater from basins, showers, and laundry for reuse in toilet flushing and irrigation, further reducing potable water demand.

Regulatory Framework

Water efficiency is assessed as a mandatory category under both Al Sa’fat (Dubai) and the Pearl Rating System (Abu Dhabi), with credits awarded for reducing consumption below baseline levels established in the respective regulations. The UAE Water Security Strategy 2036 sets national targets for water demand reduction and diversification of supply sources. DEWA publishes water consumption benchmarks for different building types in Dubai, enabling building owners and facility managers to compare their performance against sector averages and identify improvement opportunities.
