1.78 bnPeople have inhaled

polluted air over the pastdecade; this has led to

multiple diseases

12˚Chotter evening temperatures in urban areas with a population exceeding 1 million than in surrounding areas

6-10 dB(A)reductions are feasible in ambient noise levels

Five Global Case Studies - Morphology

Air Pollution Conclusion

10-20%Local reduction in concentration of PM

Height to Width Ratio as well as orientation is key for reduction

Acoustics Methodology

Five Global Case Studies - Morphology

Acoustics Conclusion

10 dB(A)Sound level reduction from emergent traffic noise

Greater impact during

night when ambient noise

level is lower.

Greater impact with

increasing distance from

noise source

Only if the base of the

building is covered,

significant reductions can

be achieved

Significant improvement can only be made for:

• Fine dust absorption

• Reduction of heat island effect

• Noise pollution

• Improved strom water management

• Reduction of behavioural agression

• Stress reduction for inhabitants

….if we tackle the exisiting building fabric,

more importantly than building new buildings…..

Way forward…… by tackling existing city fabrics
