A subtropical climate vegetated roof (SCV roof) is a type of green building practice that employs a planted soil media installed above a waterproof roof deck to obtain environmental benefits and address sustainability concerns, similar to traditional green roofs located in northern continental United States. Soil media, plant palettes, and ...
Cross hipped: The result of joining two or more hip roof sections together, forming a T or L shape for the simplest forms, or any number of more complex shapes. Satari: A Swedish variant on the monitor roof; a double hip roof with a short vertical wall usually with small windows, popular from the 17th century on formal buildings.
A properly designed and installed extensive green-roof system can cost $108–$248/m 2 ($10–$23/sq ft) while an intensive green roof costs $355–$2,368/m 2 ($33–$220/sq ft) However, since most of the materials used to build the green roof can be salvaged, it is estimated that the cost of replacing a green roof is generally one third of the ...
The roof of an earth shelter may not be covered by earth (earth berm only), or the roof may support a green roof with only a minimal thickness of earth. Alternatively a larger mass of earth might cover the roof. Such roofs must deal with significantly greater dead load and live load (e.g. increased weight of water in the earth after rain, or snow).
Roofs receive the majority of the solar radiation delivered to a house. A cool roof, or green roof in addition to a radiant barrier can help prevent your attic from becoming hotter than the peak summer outdoor air temperature [13] (see albedo, absorptivity, emissivity, and reflectivity). Windows are a ready and predictable site for thermal ...
The solar reflectance of green roofs varies depending on the plant types (generally 0.3–0.5). [32] Green roofs may not reflect as much as a cool roof but do have other benefits such as evapotranspiration which cools the plants and the immediate area around the plants, aiding in lowering rooftop temperatures but increasing humidity, naturally.
Section view through a house roof drawing showing names for parts of the structure. [clarification needed] (UK and Australia). Ctrs. means centers, a typical line to which carpenters layout framing. Domestic roof construction is the framing and roof covering which is found on most detached houses in cold and temperate climates. [1]
The plants that go into a green roof are usually sedum or other shallow-rooted plants that will tolerate the hot, dry, windy conditions that prevail in most rooftop gardens. With a green roof, "the plants' layer can shield off as much as 87% of solar radiation while a bare roof receives 100% direct exposure". [17]
