Construction and sustainability were key issues addressed in the project. With the initiative of Advancing Net Zero, the architecture achieves an impressive 60% reduction in embodied carbon and 70% Energy Use Reduction. The project includes a range of sustainable building solutions, including: - Low-carbon Glassfibre Reinforced Plastics serving as the curved colorful façade that achieved 75% reduction of embodied carbon as compared to aluminium cladding. - Durable cubical partitions made of >70% recycled palm fibre and sustainable vanity counters made of >35% recycled glass. - Air Improvement Photovoltaic system on shelter roof and walkable Photovoltaic paving that purify air and generate energy. - A "Solar Tree" comprising flexible PV panels and wind turbines serves as both an energy generator and educational landmark. - Reused the canopy, footings and underground drainage system of existing toilet, greatly minimized construction wastes.

The extensive use of locally sourced low-carbon materials not only reduce the carbon footprint but also support local suppliers and research institute. Meanwhile, real-time energy generation are shown on the digital displays to educate visitors on the benefits of renewable technologies. Tamar Toilet Advancement combines architectural innovation and materials which demonstrates that significant carbon reduction is achievable in small scale buildings while upholding both functionality and visual appeal.

It serves as a blueprint for future net-zero public facilities.
