In Macrolotto zero a city market will be built, whose facades will be covered with plants and whose air will be purified by the largest Air Factory ever built. It will be possible to consume local products and enjoy the benefits of a space regenerated by plants. Thanks to the plants, we will bring air quality, sociability and value to the former industrial area. " The project for the city market in Macrolotto Zero is divided into various interventions of plant-based solutions. The external surfaces of the former industrial warehouse will be covered with plants managed with low-maintenance technologies, and the open spaces will be re-naturalized. These interventions will generate benefits in terms of regulation of the environmental microclimate, temperature mitigation, air quality, thermal and acoustic insulation and rainwater regulation. The conversion of the former industrial warehouse in which the market was created will be a model of reuse of the abandoned industrial heritage of Prato. Plants will be the technological and vital fulcrum of the space, the first Prato example of highly innovative biophilic design. The interior spaces will host a market for local agricultural products and a large Air Factory, a system designed and developed by PNAT to completely remove air pollutants through plants. In this way the whole building will enjoy a healthy and comfortable environment: between ficus, kentia, monstere and luxuriant strelizie, you can buy vegetables grown at km 0, consume local foods and spend time in a real Urban Jungle, enjoying of the psycho-physical benefits of a full immersion in nature.
