Green Lung Retrofit

The Green Lung, here wrapped around Tower 42 in the Square Mile, could be widely applied. A network of Green Lung Retrofits would increase plant biodiversity, as well as nesting and pollination opportunities for birds and bees across the City of London.

Although retrofitted, the Green Lung would integrate symbiotically with the building's facilities.

    As good an idea as this could be (city honey is delicious!!), it maybe better NOT to apply it to landmark skyscrapers because it makes them (less) aesthetically pleasing whereas high rise residential towers are more common and will improve things for people rather than businesses - community vertical gardens?? What about the impact on fire escapes? South facing for maximum solar gain and makes a side different to the rest....

Green Lung Retrofit

Vertical gardens in the Square Mile

Shortlisted

Green Lung Retrofit proposes using excess heat from City offices to provide new vertical gardens throughout London’s Square Mile.

The concentration of activity in the City makes finding green space difficult, so Green Lung Retrofit is a vertical garden for office towers. It would clean pollutants from the air, improve oxygen levels and allow the farming of exotic fruit and produce.

Its construction would be a lightweight aluminium frame supporting an ETFE greenhouse enclosure hung from the top of the building. Solar gain from the sun and excess heat from the building’s air conditioning system would maintain the climate in the enclosure. In the greenhouse, nutrients would be provided through a misting distribution system.

Greenhouse plants would provide oxygenated air to the office interiors through a ‘coolth’ exchanger, and assist cooling of the building through plant evapotranspiration and reduced solar gain in summer months. The harvested fresh produce from the vertical garden would be sold in a farm-café and market on the ground floor.
