Unused parts of buildings could host farms

Rooftops or basements are often overlooked spaces in which we can grow food, and actually make both the building and the farm more efficient. This is how:

On Cold Weather

  • When weather is cold, it would recirculate the warm (and CO2 rich) air from the building into the greenhouse, so the farm saves on heating bills

  • The farm provides an extra layer of insulation, reducing heat loss and extending the life of its roof

On hot weather

  • When the weather is hot, it would recirculate the fresh and humidified (and O2 rich) air from the greenhouse into the building, so it saves on air conditioning bills, while the inhabitants get fresh and healthy air

  • As an extra insulation, the rooftop farm reduces the solar gain

Gas recirculation

  • There would be an exchange of CO2 and O2 between the building and the greenhouse, so plants get growth and the humans get a healthier environments through cooler and oxygen rich air

  • Buildings with boilers or machinery that produce CO2 would be able to feed it to the farm, as plants will grow better as they absorb it


Water Management


  • Both Grey waters and Rainwater can be treated and harvested to feed the plants
