Treescrapers for High Density Urban Living

'Treescrapers' is a current typology in speculative architecture
'Treescrapers' are here then? A Solution for High Density Urban Living?
A vertical garden tower, Bosco Verticale, designed for Milan has been named the Best Tall Building Worldwide for 2015 by the Council on Tall Buildings and Urban Habitat. .. From architectural fiction towards built reality. .. But can they work and are they green? Should we start believing about them?
A Passive House design calls for retention of energy and heat at low costs.
Treescrapers, a current popular typology in speculative architecture existing mostly on paper, is a building scheme that incorporates both environmental gains and high density. The porous designs look futuristic, and maybe actually stink (article doesn't say stink, whoops) so that they actually don’t look like the future of architecture.
The article speaks of carbon emissions - embodied and operational. It talks whether these are actually 'net sustainable'.

"... One is the additional force that it takes to shore up a balcony to support the weight of a tree. (Trees on balconies are the definitive features of the designs I’m lumping together under the treescraper label.) Increasing the steel reinforcement or concrete slab of a balcony increases the embodied carbon emissions for the project.
The other broad issue is the operational: the loss of heat where the balcony meets the exterior wall. Thermal bridges, essentially areas where heat loss happens at an intersection with the building’s envelope, can potentially lead to problems, namely an increased heating requirement to keep the building comfortable. There are ways to thermally break the juncture using insulation to protect against heat loss, but the question gets a bit technical for a broad look at a range of buildings. ..."
