Available in clear frosted or green fiberglass panels run about 1 to 2 per square foot. The second and even newer concept to take hold in the urban agricultural movement is what has come to be known as vertical farming. 8 to 20 per square foot. For a conventional roof.

The plants in a green roof absorb water through their roots and then use surrounding heat from the air to evaporate the water while some roofs can reach temperatures of up to 90 f in the summertime these two features can allow. Green roof temperatures can be 30 40 f lower than those of conventional roofs and can reduce city wide ambient temperatures by up to 5 f. Green roofs reduce the temperature of the building and the surrounding air in multiple ways. 1 2 in addition green roofs can reduce building energy use by 0 7 compared to conventional roofs reducing peak electricity demand and leading to an annual savings of 0 23 per square foot of the roof.

A retractable greenhouse rooftop system is probably the best option to consider since it is flexible and protects against cold climates with heavy snow loads. They provide shade to the top of a building evapotranspiration. 15 to 50 per square foot. A 2006 study by the university of michigan comparing costs of conventional and green roofs showed that on average installing a green roof costs about 22 00 sq.

Newer minds have taken the rooftop greenhouse concept and built a business model for using the rooftop greenhouse not as a research center but as a commercial production greenhouse to supply the local market.
