Client Profile

Emirates NBD is a leading banking group headquartered in Dubai, operating from a high-occupancy commercial headquarters building. As a major financial institution, water efficiency is critical to reducing operational costs, supporting sustainability commitments, and demonstrating measurable environmental responsibility across its large, daily-use facility.

Challenges / Pain Points

The bank faced rising operational pressures from outdated higher-flush systems that drove excessive water use, spiking utility bills, and increased carbon impact. With growing ESG commitments and intense focus on sustainability performance, the facility needed a smarter, reliable solution to reduce waste, costs, and service disruption.

The Propelair Solution

Propelair’s OneThreeFive toilets were specified and installed at Emirates NBD to replace traditional higher flush systems and deliver measurable sustainability and operational benefits. A total of 46 OneThreeFive units were installed, each using just 1.35 L per flush, dramatically cutting water use while maintaining performance. With asset tracking and low flush volume, OneThreeFive supports cost reduction, ESG targets, and reliable washroom operation in a high-occupancy commercial environment.
