You can let TfL know your views by completing their questionnaire or sending an email to crossrail2@tfl.gov.uk . TfL's public consultation closes today 8th January at 5pm .
We reproduce an below an extract from our representations which relates to our proposals for surface level ventilation shafts.
6 Ventilation Shafts – design and location
Construction of surface ventilation shafts in a tight urban area like Dalston carries the risk of demolition of character buildings and an obvious potential to create a featureless void which will make a negative contribution to the surrounding area which, in Dalston’s case, is one of considerable sensitivity.
We wish to make proposals to Crossrail2 to consider mitigating this. We wish to explore with TfL
- the recovery of heat generated in the Underground to supply heat and/or hot water to neighbouring properties ( most likely to those developed on left-over land which Crossrail2 acquires for its railway construction operations)
and
- the capture at surface level, the surplus heat and CO2 emissions from the Underground which would otherwise go to waste, for their use in plant growing.
The recycling of heat generated in underground railways is not a novel idea, and has been utilised in Stockholm, Paris and Islington. Heat recovery would contribute to significant energy saving.
The recycling of surplus heat and CO2 emissions for plant growing is innovative and would contribute to bio-diversity. The imaginative development of vent shafts could, by good design, create such functionality and mitigate the environmental damage caused to their locations. The capturing heat and CO2 has been devised and successfully trialed in Dalston by the award winning scientist Charlie Paton who also invented seawater greenhouses.
