In September 2016, engineering contractor Arup published a report ‘Cities Alive: Green Building Envelope’, examining the possibilities of cleaner, greener and healthier human ecosystems.

The report, written by a global collaborative team of Arup specialists, explores the application of green infrastructure to the surfaces of both new and existing inner-city buildings in five major cities – Berlin, London, Los Angeles, Melbourne and Hong Kong.

The range of conclusions includes the following:

=== Air pollution ===

* Green facades can result in local air pollution reductions of between 10-20%.
* Level of reduction is dependent on the ratio of the building height to the street width.
* Green envelopes provide opportunities to improve air quality in selected areas.

=== Acoustics ===

* Green facades could reduce sound levels from emergent and traffic noise sources by up to 10dB(A).
* However, green facades have a greater acoustical impact with increasing distance from the noise source.
* When ambient noise levels are lower, such as during the night, green facades are likely to have a greater acoustical impact.

=== Urban heat island (UHI) effect ===

* Green facades benefit pedestrian circulation by removing 50% of the solar radiation.
* Most effective at reducing UHI in denser urban centres.
* Reductions in peak air temperatures of up to 10oC were achievable, although for most areas, the mean reductions in UHI were a fraction of a degree compared to the peak.
* Cities that are denser and have more concrete have more to benefit than those that are already quite green.
* Cities with wide streets and low-rise buildings could benefit from more greenery at street level.
