Green Building Envelope
Strategic Research to make the benefits meassurable
„Cities need green sizes S, M, L and XL otherwise the human ecosystem is incomplete.“ Gil Peñalosa, CEO „8-80 Cities“ quoted in „Happy City“ by Charles Montgomery (2013)

Green Building Envelope ‌Why bother? ‌Why bother in Berlin?
...Berlin is a green City! Green Lungs of cities
1.78 bn People have inhaled polluted air over the past decade; this has led to multiple diseases
12ËšC hotter 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 The problem we are facing
Three major recognitions which are well known, but have not been quantified‌.. ‌.a challenge which we have resolved

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
Five Global Case Studies - Morphology
Acoustics Methodology
Five Global Case Studies - Morphology
Acoustics Conclusion 10 dB(A) Sound level reduction from emergent traffic noise
Only if the base of the building is covered, significant reductions can be achieved
Greater impact during night when ambient noise level is lower.
Greater impact with increasing distance from noise source
