asphalt shingles that are popular and sought-after roof materials. House owners ponder and prefer to exploit well-known materials and often pick asphalt shingles as the best choice for roof updates and new roof establishments when turning to roofing specialists. Speedy roof repair plays an important role in such choice, which is why clients of roofing companies prefer fast installation and reconstruction of asphalt shingles which could be performed within 1-2 days.

Green Roofs: Types, Advantages, Experimental and Simulation Studies, Comparison (Green, White & Black)Previous research works suggest that buildings with green roofs are eco-friendly. For example, green roof i.e. green vegetation on roof top retain storm water during storms and heavy rain, which reduces amount of water entering city runoff system. First, the green roofs retain excess water, and later they return this water to atmosphere by evapotranspiration. Consequently reduces runoff helps in reducing amount of pollutant which enter a non-regulated storm water system.These benefits have been demonstrated in many experiments which were conducted across many sites, cities, and landscape. In addition, green roofs help in regulating internal temperature of buildings, which reduces overall energy consumption of a given building. Buildings™ energy consumption reduces because green roofs provide shading, increase thermal mass, and cool the buildings™ internal temperature. However, amount of energy saving depends on various factors such as design of green roofs, climatic season, and level of insulation or thickness of vegetation provided on the roof. Research statistics suggests that amount of irrigation on the green roofs also influence amount of energy reduction. For example, during summer proper irrigation of green roof reduces demand of buildings™ air conditioning requirement from 98.90% to 90.80%; similarly, during winter buildings™ heating requirements comes down from 38.30% to 27.40%. Therefore, it can be concluded that benefits of green roof vegetation contribute to a sustainable development towards combating climate change. Developing green roof buildings are better alternative to other greening strategies such as street trees and green city gardens which is a challenging task for city administration in cities with higher building fraction i.e. lesser land availability for planting trees due to presence of large number of buildings.

The indoor environment is contaminated by the products of microbial growth, such as spores, allergens, volatile organic compounds, endotoxins, mycotoxins and so on. According to some estimates, between 10 and 50 per cent of indoor spaces across Asia, Australia, Europe and North America are affected to some degree by dampness. The presence of dampness in indoor spaces shows wide variations across different climate zones. The problem is more acute in the high-humidity conditions prevailing in areas close to the coast or in river valleys and basins. Microorganisms are everywhere, but the availability of moisture in or on materials is particularly conducive to the propagation of a whole range of microbes, from fungi, to actinomycetes and other bacteria. In addition to these favorable conditions, dust provides an adequate supply of nutrients to sustain extensive microbial growth. Materials that retain moisture and accumulate dirt easily provide the optimal conditions for rapid growth of these organisms. As a result of this, the indoor environment is contaminated by the products of microbial growth, such as spores, allergens, volatile organic compounds, endotoxins, mycotoxins and so on. While it has not yet been possible to conclusively prove a causal relation between these products to adverse health effects, persons with atopic and allergic symptoms are hypersensitive to biological and chemical agents found in damp indoor conditions. Research is also bringing to light the detrimental effects of damp environments on atopic individuals as well. In this section, we will provide a brief summary of some important varieties of microorganisms known to be particularly active in damp indoor environments. (more…)Read More >>
Asphalt Shingles Recylcing: Waste Management, Utilization of Reclaimed Materials, Testing, Study of Grading, Performance Tests, Health IssuesSustained environmental focus in recent years has triggered a renewed consciousness of recycling practice and its extensive application to an increasing number of materials. The recycling of asphalt shingles in particular is sought out for the benefits resulting from commercial applications potential and the conservation of landfill space. Currently, the practice is partially limited by environmental and health concerns regarding the content of harmful materials embedded in aged shingles. Another aspect is the behavior that can be expected in regards to the performance of the asphalt used in road pavement. Furthermore, the technology necessary for recovering and reusing asphalt shingles has been improving for more than three decades and gaining trust from regulatory authorities and road pavement contractors alike.

Green Roofs, Slate Roofs, Bitumen, Asphalt Shingle, EPDM, Metal, Flat, Torch Down, Wood: concept, installation, functionality, environmental benefits, sustainability & maintenance.Before actually into the thick of the topic, we need to understand the need for the green roos. Perhaps some statistics will help us illustrate this.
- The rate of construction and ‘construction utilisation’ has more than tripled in developing countries in the last two decades.
- Land reclamation, has emerged as the only option of dealing with this issue. However, land reclamation is not only extremely expensive, it is also largely detrimental to the environment.
