Green roof and greenhouse differences.

Available in clear frosted or green fiberglass panels run about 1 to 2 per square foot. Green roofs reduce the temperature of the building and the surrounding air in multiple ways. 8 to 20 per square foot. They provide shade to the top of a building evapotranspiration.

On the other hand an open greenhouse roof allows fresh air in the hot months. 15 to 50 per square foot. 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. 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.

Fiberglass panels are commonly used to cover greenhouses as they are durable lasting for up to 20 years. 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. 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. The second and even newer concept to take hold in the urban agricultural movement is what has come to be known as vertical farming.

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.
