Vertical greenhouses: the economics?

This data-file models the economics of vertical greenhouses, an emerging method for growing greens, fruits and vegetables close to the consumer, in large multi-story facilities, lit by LED lighting.

The economics can be attractive, with 10% IRRs in our base case condition, off 50kg/m2/year yields and $7.5/kg produce pricing.

However the CO2 intensity will depend heavily upon the CO2 intensity of the underlying grid,  as our numbers assume 1,000kWh/m2/year of LED light is required.

Data in or models are sourced from technical papers, which are also summarized in the final three tabs of the model.
