Interesting proposal, but the author/s need to clearly think through what it means to scale up this idea-- how would having green walls on every building look like? For existing installations, maintenance has proven to be a significant challenge that brings potential benefits into question. Also, what are the impacts on the structure itself? All these need to be evaluated against other alternatives of introducing vegetation into urban spaces
Idea has merit but the proposal is not well organized and does not address barriers to adoption; there is no energy balance calculation with respect to total potential CO2 uptake
Comments from Judge 1:
This proposal builds off of the "green roof" concept and applies it to vertical surfaces. The proposal would be strengthened by investigating designs that would apply to more building types and management of green space externally (could include vertical maintenance lift).
Comments from Judge 2:
In principle vegetation can offer many energy and environmental benefits. But you have not shown that your proposal is practical. Provision of adequate water to the plants requires infrastructure not described. Many buildings are unsuited, because they cannot cope with the extra weight, or plants growing may damage building facades. Keeping plants alive in extreme conditions can be a challenge. There can be a lot of maintenance costs associated with green walls. More detail in relation to the above issues is needed. And maybe you should select a demonstration site and negotiate agreement with its owners. This way you can identify many of the challenges and develop responses to them.

Also as mentioned at the end of "What actions do you propose?" a college owner has already agreed for the idea. It’s named silver oak college located in my hometown Ahmedabad also a temple trustee has agreed but won’t allow to cover the domes due to religious reasons.

Please note that there is a proposal for buildings which cannot provide enough water which is mentioned in related proposals section. Also the main infrastructure requirement for this proposal is water available on each floor where plants are grown.
