On the other hand, conventional roofs are the more common type of roofs made of such materials as glass, wood, concrete, and bricks. This paper draws a comparison between the green roofs and the conventional roofs. Types The conventional roof has many types. Types of the conventional roof include but are not limited to the single ply roofs, built-up roofs, metal roofs, and asphalt shingle roofs. Single ply roofs are sheet-like membranes manufactured in the factory. Thermoplastic membranes and thermoset membranes are the two types of single ply membranes. Built-up roofs contain several layers of reinforced membranes and modified bitumen roofs. Built-up roofs are the most common as well as the oldest type of conventional roofs. They are also called as the gravel or tar roofs. There are three components in the built-up roofs, which include a layer of waterproofing, a reinforcement layer, topped with a surfacing layer. It is installed with the help of asphalt or coal tar. Structural metal panel roofs are used for roofs with low slopes as they have the characteristic quality of water barrier. They can also be used for roof assemblies with steep roofs. The structural metal panel roofs are constructed in such a way that water cannot pass through the joints. These roofs are installed in a broad range of substrates. Asphalt shingle roofs are amongst the most commonly used roofs where the slope is steep. There are two types of asphalt shingle roofs; organic roofs and fiber glass roofs. “Organic consists of paper saturated with asphalt to make it waterproof with a top coat of adhesive with embedded ceramic granule” (gogreenconstructionnow.com, n.d.). Owing to their greater weight, organic shingle roofs offer better blow-off resistance as compared to the fiber glass roofs. Roof shingles may contain single or multiple layers, but all types contain an adhesive strip which is sun-activated and serves as a sealant for the rows. There are three main types of green roofs; extensive green roofs, semi-intensive green roofs, and intensive green roofs. The extensive green roofs are used in ecological landscapes. The type of vegetation used in the extensive green roofs ranges from moss and herbs to grasses. The depth of substrate in the extensive green roofs is between 60 mm and 200 mm, and their weight is in the range of 60 kg/m2 to 150 kg/m2 (Livingroofs.org, 2012). The cost of extensive green roofs is the lowest of the three types of green roofs. The semi-intensive green roofs are used in ecological landscapes as well as gardens. The type of vegetation employed in them includes herbs, grass, and shrubs. Their depth of substrate ranges from 120 mm to 250 mm whereas their weight is generally between 120 kg/m2 and 200 kg/m2. The cost of semi-intensive green roofs is periodic. The intensive green roofs are used in parks and gardens. The type of vegetation used in the intensive green roofs ranges from perennials and shrubs to trees. Their depth of substrate is generally 150 mm to 400 mm. The weight of the intensive green roofs is between 180 kg/mm2 and 500 kg/mm2. The cost of intensive green roofs is the highest of the three types of green roofs. Cost Payne et al. (n.d.) conducted a research to compare the expenses associated with the green roofs to the cost of conventional tar roofs to identify the places where the installation of a green roof is more feasible economically than the conventional roof.
Green Roofs vs Conventional Roofs School Green Roofs vs Conventional Roofs Introduction Green roofs are the roofs with vegetated surfaces. Green roofs have been used for a long time in history particularly in the domestic houses. Generally, conventional roofs have been used more than the green roofs in buildings in the urban areas…
This is damaging the environment and increasing the temperature of the world. Oceans are melting and seal levels are increasing. This phenomenon is known as global warming. The dangerous consequences of such climatic change are forcing the world to come up with techniques that are environmental friendly.
The biggest benefit of green buildings is that they ensure the well-being of humans. According to the U.S. EPA, three most fundamental objectives of the programs centered on green building are “to increase efficiency in the use of water, energy; to protect the health and increase the productivity of the building’s residents; and to reduce pollution and waste”.
It is arguable that for the vast majority of the population who are not directly involved in design good design passes notice less and passing notice less is its highest achievement. Sympathetic design passes without any notice as its form and function is perfectly realized: It works.
It was started by Samuel Hahnemann (1755-1843) a haemopath in 1810. Although allopathic medicine was rejected as a term by mainstream physicians it was adopted by alternative medicine advocates to refer to conventional medicine. With the term allopathy which also means “other than the disease” Hahnemann intended to point out how physicians with conventional training employed therapeutic approaches that in his view merely treated symptoms and failed to address the disharmony produced by underlying diseases.
The aim of the modernist is to know and take hold of nature and in line affect our individual future and as well the destiny of the world sets up relative to the Renaissance humanism. These rational underpinnings shaped the aesthetic scheme of high modernist architecture.
Solar energy is not new and has been used traditionally in most domestic operations like drying harvested food and clothes, lighting fire through proper reflections, and warming houses among others although it had some limitations. However, its past limitations for use in a broad range of applications has been eliminated through the use of advanced technology that enables better methods of capturing the energy, converting, and storing it for diverse uses.
Leadership in Energy and Environmental Design sets the standards for the environmentally sustainable construction. The program was initiated in 1998 in the US and has so far managed to undertake over 14,000 projects.
Considerate selection of sites can be very beneficial in reducing the disturbance to the public, animal and plant life.
The idea of attempting to outlaw any tastes/lifestyles is in fact "oppressive", but especially when viewed through the lens of the ideas of a philosopher such as Nietzsche. This is particularly the case when considering censorship through one of his most influential works, Beyond Good and Evil.
Moreover, 30 percent of the buildings supplies are from recycled materials and 57 percent are from local producers, including the plants which were grown at NAU’s Green House. Most importantly, the layered materials of the
