TaiKoo Hui Sustainable Washroom
A bright grotto, a contemporary abstraction of nature, to refresh shoppers amidst the dazzling commodities, is our design concept for the underground toilet. Cyclorama setting is adopted, new white wall wrap around existing columns and wall to join the ceiling seamlessly with curve surfaces, create a bright and clean ambient. Idea of recycle/reuse is made visible by showing the reused aggregates on floor, and plants irrigated by local grey water.
UNIQUE PROPERTIES / PROJECT DESCRIPTION:
The design aims to be role model of sustainability in commercial sector, by reuse, recycle and reduce. Minimum alterations are made to original layout. New terrazzo floor is formed by aggregates made from original stone finishes. White, seamless surface enhance brightness and avoid dirty corners. Plants help to purify air, add oxygen and life, irrigated with greywater from wash basins. Sustainable products are applied: GRG ceiling, water tap and hand dryer, waterless urinal, water-saving and vacuum toilet
OPERATION / FLOW / INTERACTION:
The design aims to raise the environmental awareness in public realm and to become the role model of sustainability in the commercial & retail sector. Indoor plants irrigated by basin greywater to purify air, raise indoor oxygen level, and add life and colors of nature. Integrated water tap cum hand dryer, waterless urinal, vacuum toilet and water saving WC are applied to saves water usage by 80%, reduce waste volume by 60% on a daily basis. LED lighting fixture applied help to save electrical consumption and maintenance cost.
PROJECT DURATION AND LOCATION:
The project is located at the prime shopping mall of TaiKoo Hui in Tianhe commercial center of Guangzhou, China. It started in June 2015 and finished in Feb 2016.
PRODUCTION / REALIZATION TECHNOLOGY:
Minimum alterations are made to the original efficient layout, to minimize structural and piping alteration. The floor is a newly-casted dark grey terrazzo stone. The original sandstone and grey tiles are crushed as aggregates for the new terrazzo, forming unique golden chips to reveal the idea of recycle.
Glass Fiber Reinforced Gypsum (GRG) panels are used to form the curved surfaces and ceilings. The panels are made to size and are designed to minimize excessive framing. The GRG material itself is also considered as post-consumer recycled material.
SPECIFICATIONS / TECHNICAL PROPERTIES:
Area: approx.. 135 sqm
Room height: approx. 2.8m
Material/ product applied: Glass Fiber Reinforced Gypsum (GRG) panels, grey terrazzo stone with recycled stone aggregates, integrated water tap cum hand dryer, waterless urinal, vacuum toilet, water saving WC, LED spot light, indoor vertical plant
Energy saving: water usage reduced 80%, waste volume reduced 60%, electricity saving on daily basis

The design aims to raise the environmental awareness in public realm and to become the role model of sustainability in the commercial & retail sector. In-depth researches on sustainability design for commercial use are conducted at early design stage, that focus on spatial planning and optimization, material recycle and reuse in construction phase, water recycling and saving, energy saving and waste reduction. It lead to a good result that attain up to 80% water and energy saving, and the design is highly popular and welcome by the public, with wide coverage in the local media.
Situated in the commercial center of Guangzhou, the TaiKoo Hui complex receives tens of thousands of visitors daily, and its amenity facilities require an upgrade. The sustainable design washroom aims to raise the environmental awareness in the public realm and to become the role model of sustainability in the commercial & retail sector. The design aims to tie back to nature, formally as well as environmentally. Sustainability, spatial sculpting and human comfort drive the whole design.
