Introduction of the winning projects：

ReCondense – Green Engineering Cycle System for Air-Conditioning Condensate Water Recovery :

The ReCondense project introduces an innovative green engineering cycle that transforms wasted air conditioning condensate into a sustainable non potable water source. Condensate is collected from air handling units, stored, then processed through sand filtration, chemical disinfection dosing, and final UV sterilisation. Treated water is automatically distributed for landscape irrigation and general building cleaning. The modular, low cost design is compatible with existing building infrastructure and supports Hong Kong's “Carbon Neutrality 2050” goal. The proposed system is expected to significantly reduce municipal water consumption while contributing to long-term carbon emission reductions.

Key Features

Modular, low-cost design – Easily retrofitted into existing building infrastructure.

Automated control – Minimises manual operation.

Scalable – Suitable for commercial, institutional, and residential buildings.

Expected Benefits

The ReCondense system aligns directly with Hong Kong’s "Carbon Neutrality 2050" goal. Preliminary estimates indicate:
