Container gardens on roofs, where plants are maintained in pots, are not generally considered to be true green roofs, although this is debated. Rooftop ponds are another form of green roofs which are used to treat greywater.<\/p>\n<p>Green roofs serve several purposes for a building, such as absorbing rainwater, providing insulation, creating a habitat for wildlife, increasing benevolence and decreasing stress of the people around the roof by providing a more aesthetically pleasing landscape.<\/p>\n<p>There are two types of green roofs: intensive roofs, which are thicker, with a minimum depth of 12.8\u00a0cm, and can support a wider variety of plants but are heavier and require more maintenance, and extensive roofs, which are shallow, ranging in depth from 2\u00a0cm to 12.7\u00a0cm, lighter than intensive green roofs, and require minimal maintenance.<\/p>\n<p>Environmental benefits:<\/p>\n<ul>\n<li>Reduce heating (by adding mass and thermal resistance value)<\/li>\n<li>Reduce cooling (by evaporative cooling) loads on a building by fifty to ninety percent &#8211; a concentration of green roofs in an urban area can even reduce the city&#8217;s average temperatures during the summer<\/li>\n<li>Reduce stormwater run off<\/li>\n<li>Filter pollutants and carbon dioxide out of the air which helps lower disease rates such as asthma<\/li>\n<li>Filter pollutants and heavy metals out of rainwater<\/li>\n<li>Help to insulate a building for sound; the soil helps to block lower frequencies and the plants block higher frequencies<\/li>\n<li>Increase agricultural space<\/li>\n<\/ul>\n<p style=\"text-align: center;\"><img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-full wp-image-78\" src=\"http:\/\/zoldenergiablog.hu\/en\/wp-content\/uploads\/sites\/2\/2014\/05\/shutterstock_185941676-300x244.jpg\" alt=\"shutterstock_185941676-300x244\" width=\"300\" height=\"244\" \/><\/p>\n<p>It is estimated that the installation of a green roof could increase the real estate value of an average house by about 7%. Reduction in energy use is an important property of green roofing. Depending on the region in which a green roof is installed, incentives may be available in the form of stormwater tax reduction, grants, or rebates.<\/p>\n<p>The main disadvantage of green roofs is that the initial cost of installing a green roof can be double that of a normal roof. Depending on what kind of green roof it is, the maintenance costs could be higher, but some types of green roof have little or no ongoing cost. Another detractor is that the wildlife they attract may include pest insects which could easily infiltrate a residential building through open windows.<\/p>\n<p>A number of European Countries have very active associations promoting green roofs, including Germany, Switzerland, the Netherlands, Norway, Italy, Austria, Hungary, Sweden, the UK, and Greece. The City of Linz in Austria has been paying developers to install green roofs since 1983.<\/p>\n<p>Source: <a href=\"http:\/\/en.wikipedia.org\/wiki\/Green_roof\">http:\/\/en.wikipedia.org\/wiki\/Green_roof<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A green roof or living roof is a roof of a building that is partially or completely covered with vegetation and a growing medium, planted over a waterproofing membrane.
