This project proposed a 2020 resolution ‘the crust’, which would be a new version of air rights utilization in NYC, to face the urgent climate change issue. Researching into the block running from 54th to 55th Street and 6th to 7th Avenues, with 683 residents and 233 apartments. The ‘crust’ would function as socio-ecological urban infrastructure in four aspects- food, energy, waste and water-by connecting itself with original buildings. All of the infrastructures would not only manage the City of New York to honor the 2050 plan target by 52%, but also it would move from a model of unequal territorial distribution of the environmental cost of its daily functioning, to an evenly distribution of environmental responsibility.
