The benefits of green roofs · Improve the drainage system · Increase roof life · Increase thermal performance · Help the environment. Moss has amazing properties when it comes to absorbing and retaining pollutants and carbon dioxide. Green roofs benefit wildlife and ease the burden on drainage systems by reducing runoff from They provide additional insulation and extend the life of the roof by protecting its surface from the elements. Sedum is a plant genus that includes a variety of species.
In nature, these plants are found in open, dry and stony soil. Drought and the challenging environment of a roof reproduce the natural conditions in which sedum grows well. Mosses are also suitable for living on exposed roofs with minimal soil and little water. They recover easily after periods of drought and spread during cold seasons.
These characteristics make moss an excellent complement to sedum in the construction of a green roof. Mosses and lichens grow naturally on most roofs, but a green roof is intentionally designed to support vegetation. Holly Hedge, a wedding and event venue in New Hope, Pennsylvania, installed a habitable moss roof in a small children's cabin made of cordwood. Colder roof temperatures caused by a green roof help increase the efficiency of mechanical roof equipment by making roof air cooler.
Not only do green roofs help reduce the urban heat island effect by covering dark surfaces of conventional roofs with vegetation that absorbs less heat, but they also use solar radiation to evaporate water from growing media and to perspire (absorbing water through plant roots and its release through it). its leaves (in the form of vapor), the moisture of the plants. Increasing the R value (a measure of a material's resistance to heat flow) of the roofing system, together with the reduction of roof temperatures, decreases HVAC loads, resulting in savings in energy costs. In some cities, buildings with green roofs may be eligible to pay lower stormwater management fees because green roofs reduce the amount of stormwater leaving the site.
A green roof can increase the life expectancy of a roofing system by protecting roofing materials from direct ultraviolet radiation and extreme temperatures. A green roof protects roofing material from external influences, such as sun, rain, wind and temperature fluctuations, and doubles or triples the lifespan of the roof up to 60 years or even longer. Transplant nets were used to protect the moss from birds that might try to turn it upside down for insects or worms, and to prevent the moss from falling off until it had time to attach to the mats. Another application for green roofs involving Moss Acres was at the Faculty of Human Ecology at Cornell University, where four preplanted boxes were planted on the roof and then delivered to the University Water Retention of 26% of insulating properties: green roof systems composed of moss mats and a Lower water-retaining layer combine to achieve significant stormwater retention capacity, protect the roof membrane and provide significant insulation capacity.
A well-maintained green roof can more than double the number of years before a roof needs to be replaced compared to a standard roof, offsetting some of the additional installation costs. Only a modest roof area has been installed in Sweden, but the municipality of Malmö, the country's third largest city, has included the consideration of green roofs as part of the permit granting process. The hives on the roof of Chicago City Hall help pollinate green roof plants and provide a home for the urban bee population. A dark and heat-absorbing roof surface increases the demand for mechanical systems, making it difficult to properly cool a building, while a green roof lowers the temperature of the roof and, therefore, of the building itself.
