“The rapid urbanization process has increasingly worsened living environment in Beijing. What is the alternative to regenerate water resources and at once improve air quality?”

A 100m by 100m urban sample is used as an apparatus to repeatedly assessing how the and integrated façade is designed and achieve a regenerative output in term of the reclamation of water and dust filtration in the prototypical mixed-use community.

Water is regenerated through a cycle of systems and it is essential to maximize the water regenerated and minimize the energy used. Water is regenerated by:

  1. Filtering income mixture of water and dust pollutants[1]
  2. Regenerate filtered water for internal/external cooling, irrigation, domestic use
  3. Recharge these secondary uses of water back into the water grid

Dust is extracted as a by-product containing precious metals and minerals that can be reused such as platinum, palladium, rhodium and fertilizer. [2]

The challenge lies on this cycle of systems. Within the community housing buildings are dominant. To integrate these systems the façade of these housing are the key in which performs filtration, regeneration and replenishment of water. The façade undergoes a series of simulations and assessments in order to finalise with an efficient filtration system separating water and dust; maximise water regeneration needed for the community uses; and the maximum water replenishment rate. The assessments are therefore in three parts and assess by:

  1. How and which materials best achieving the above criteria
  2. Geometry of the overall integrated façade within the community
  3. Overall cycle of systems to deliver the most efficient regenerative community

By undertaking a series of assessments based on these factors, the proposal of the prototypical mixed-used community are constantly refined and retuned, maximising the water regeneration. The final proposal sets a regenerative model for future urban expansion and Beijing can continue with its urbanization without compromising the current and future inhabitants’ quality of urban life.
