Green Roof Advantages And Disadvantages

This chapter is mainly intended to suggest a springboard for filling gaps between analysis (method) and practices. Based on the result of suitability analyses under Scenario 1, ‘Equal Consideration,’ which places equal weight on the six criteria, this chapter tries to show how the four selected GI practices –rain gardens, bioswales, green roofs, and permeable pavement– can be located suitably, balancing the effectiveness of and demands for GI. The reason why the first scenario was selected for the suggestion is that since the other three issues are basically grounded on uncertain and unpredictable factors such as urban growth and climate change.

#19. The green roof provides shade, remove air particulates. Protects the roof from sun damage, and cool the air as water lost moist from plants leaves.

Every group had its own suggestions for green infrastructure. The most popular method among the projects was the implementation of green roofs. As every group stated, green roofs can help regulate temperatures inside buildings, saving costs on heating and cooling. They are handy in capturing storm water runoff, which can then be used for food production. Group A did a good job showing these benefits, but neglected to consider the possible detrimental

The roof provides an important layer of protection to any home, be sure to keep it in tip top shape. Click to visit website of a professional who can assist in the roofing needs of any

Anyone who has owned an asphalt shingled roof has seen the black streaks that form in the areas on the roof that get less sunlight. Commonly mistaken for mold, these streaks are actually algae that feed off of the limestone filler used in the shingles. This algae is not only an eyesore, left unchecked it can cause the granules on your shingles to fall off. It is a good idea to get rid of this menace as soon as you notice it.

Are you concerned about the impact that you make on the environment? This may make cedar roofing a great choice for your home. Green families love the roofing material because it does not harm the environment during its creation by burning fuels or using chemicals. Using

Slate roofing has proven to be a favorite of those that are going green, as well as those people that want their roof to stand out and have a ton of eye appeal. Slate roofing is basically utilizing slabs of rock, which are laid out just like other types of roofing. One of the biggest benefits of slate roofing is the fact that the shingles are one hundred percent natural, so those people that are concerned with protecting the environment or having a complete green house, this is probably your best option.

Keeps you out of the weather. The weather plays a big factor in how often and when you can use your deck. By putting a roof over your deck you can use is rain on shine. Another benefit concerning the weather is that it can make your deck last longer. This is due to the fact that it doesn't have to suffer as many natural elements

Green buildings could become one of the main factors to preserve our rapidly decaying environment. There is no easy way to define a green building, but a green building is essentially a structure that amplifies the positives and mitigates the negatives throughout the entire life cycle of the building (Kriss, 2014). There are many definitions for a green building, but all of them include the planning, designing, constructing, and operating of the building while taking into huge considerations of the energy use, water use, indoor air environment, materials used and the effect it has on the site the green building is being built on. The first green buildings dates back to as far as the 1970’s, when solar panels went from experiments to reality. Green buildings were not as popular as they are today due to their extremely high pricing. With technology rapidly growing, solar panels are becoming cheaper and cheaper, making the transition to creating green buildings more affordable. This is the primary reason for the increased growth of green buildings today. A modern company that is paving the way to the growth of green buildings named LEED, Leadership in Energy and Environmental Design, focuses primarily on new and effective ideas for environmentally friendly buildings projects. With more than 60,000 commercial projects worldwide and 1.7 million square feet being certified every day, LEED is one of the leading groups for promoting green buildings. LEED has popularized the entire

Materials and Methods: This paper present a design of depth of shallow 2 inch greensmart blanket, green roof mathematical models, cistern, plant types selection, and calculate the f factor. The paper collect data from their design green roof and compare the data with the authors’ previous work. Traditional green roof is laid loose soil, greensmart is a two inch blanket.

Step 6 Transpiration: When water gets absorbed into the soil plants actually use it for photosynthesis and the excess water gets pushed out and goes back into the atmosphere as water vapor.

Slate roofing has been a popular method to have roofing for many centuries. They are durable, aesthetic and long-lasting. However, it is true that roofing services agree that they are heavier than other roofing materials; therefore, they are hard to install. Further, the materials need careful attention as slate tiles in single units can break easily. Keeping aside these general disadvantages that can be associated to most roofing materials, slate roofing offers the following benefits:

Green roofs are example of green infrastructure that provides storm management through layers of absorbent materials on the roof’s surface capable of holding water. These layers consist of some form of vegetation like grass, a growing medium that enables the vegetation to cultivate, a filtering layer that allows only water to pass through, a draining layer, a waterproof barrier that prevents water from going through the roof and the roof structure that is made from a material like concrete, wood or steel (City of Alexandria). Green rooftops absorb 15%-90% of runoff rainwater that comes in contact with the roof, and that large variation in absorbency is based on the vegetation and growing medium used (Lake Superior Streams). The type of vegetation selected ultimately depends on several factors, such as the climate, access to sunlight and the depth of the growing medium as shallow growing mediums (5cm) can only sustain plant species with short roots such as sedum while grasses, herbs and wildflowers can be sustained in medium-depth growing mediums (10cm) and columbines and asters can live in growing medium with deeper depths (15cm+ (Green Garage). The depth of the growing medium correlates with the vegetation that can be grown, as the roots of more absorbent plants tend to need more space. It is important to note that the soil used on green roofs is not the same type as ordinary soil found in the ground, but that it is instead engineered to have certain characteristics

Progressive deterioration of global warming and protection of environment are important areas of interest for the whole world. Buildings as an underlying cause are responsible for global warming. Edwards (1996) pointed out that building has a key role to play as they are one of the major sources of energy consumption. And he (1996) also stated with some statistics to support this point that buildings account for about half of all global – energy, water, and raw materials as well as in the EU (Edwards, 1996, P. xiv). And another data is that buildings constitute about 45 per cent of carbon-dioxide emissions (John, 1998, P. xi). In addition, buildings should be accountable to most of land loss in agriculture. But it does not
