The invisible moat of the headquarters building of the sponge city: This is an important sub-technology under the sponge city strategy, surrounding the headquarters building. A water storage channel with a width of 1 meter and a depth of 5-10 meters is set underground next to the outer wall. Rainwater from the roof of the headquarters building is collected through rainwater downpipes into the water storage channel. Above the water storage channel, a greening channel is set up, which contains soil where plants grow. The rainwater collected in the water storage channel rises to the soil through capillary action, keeping the soil moist for plant growth. The evaporation of soil moisture and the transpiration of plants carry away heat while cooling the headquarters building and purifying the air. This can also lower the temperature of the lower floors by 3-5 degrees, corresponding to a 30-50% reduction in air conditioning electricity consumption, thereby reducing carbon emissions.

Rainwater Utilization on the Roof of Sponge City Manufacturing Workshops: This is an important sub-technology under the Sponge City strategy. Surrounding the workshop or factory, a water storage trench with a width of 1-3 meters and a depth of 5-30 meters is set underground close to the outer wall. Rainwater from the roof is collected through rainwater downpipes into the water storage trench. Above the water storage trench, a greening trench is set up, which contains soil where plants grow. The rainwater collected in the water storage trench rises to the soil through capillary action, keeping the soil moist and providing water for plant growth. The evaporation of soil moisture and the transpiration of plants carry away heat, cooling the building and purifying the air.
