Given the heights and close proximity of buildings in this high density development, have modelling studies, including wind tunnel and fluid dynamics testing, been undertaken to determine the micro climate that will be created in high wind conditions? External high winds passing through the completed development and in between the buildings will be accelerated. This can create difficult conditions at street level due to the ‘downdraught effect’ and ‘channelling effect’ the new buildings are likely to create in windy conditions.
The higher the buildings are the worse this wind acceleration will be. The new residential tower will increase these effects particularly given its exposed location at the north west corner of the site development. Lee residents who have experienced accelerated high winds at street level at that corner, with the 8 storey existing office tower currently located there, should be aware that these are likely to increase. The more so with the latest proposal to increase the height of the residential tower to 18 storeys.
Predicted climate change is expected to lead to increased wind speeds in London, particularly during winter. The UK Climate Projections report (UKCP18) suggests that winter wind speeds will increase in the second half of the 21st century, and the frequency of winter storms will also increase. This is well within the expected lifespan of the proposed development.
I’ve seen no evidence in the planning submission that these issues have been addressed.
I would be interested as to the real reason why the existing now derelict development failed so badly and so quickly.Have any lessons been learned from the death of the high street and the online shopping revolution. It seems due to land shortage In London the only way is up and this vertical stacking while not desirable aesthetically or socially is being allowed to meet housing demand but then you hear about many of these towers remaining vacant sold to investors for profit later. So one wonders what measures are taken to stop this .
