Implementing Green Roof For Small Dwellings : Case Of Residential Units, Auckland, New Zealand

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

One World Trade Center is an ideal representation of what green building is. It is not to say that the design and construction of this structure was not without its challenges. In this paper, I will discuss the factors that qualified the building for LEED certification. I will also discuss the challenges the building faced while pursuing this certification and what was done to overcome these challenges.

Need to replace your roof, and looking into eco-friendly material as an alternative? Then you may have run across wood shingles as an option for your home’s roof. While they are considered a green roofing material due to the natural wood they are made from, there are some disadvantages of using the material. By weighing these advantages and disadvantages, you can decide on if the material will be best for your home.

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

The most common home that is developed has either a gable roof or a hip roof. A gable roof has a ridge in the center of the roof and slopes downwards in two directions. This type is easy to develop and can be used for almost any type of building. Gable roofs look like an “A” after constructed. Hip roofs are different than gable roofs. A hip roof had four sides that go down in each direction connecting to the top of the wall.(Constructionknowledge.com) Building a hip roof will use more materials and increase time. When constructing the roof you wanna end in the center and start on the top of the walls. When constructing the exterior part of the roof there are numerous ways to do it. There’s asphalt shingle, slate, metal roofing, and much more. Slate roofs are individual smooth flat pieces that of rock that come in colors such as gray, red, green, and more. Although slate roofs are very durable and fire-resistant they are also very expensive and heavy.(By Jeannie Matteucci, top 6 roofing materials) The most commonly used exterior roofing method in North America is asphalt shingling. It is an inexpensive and fairly easy to install method. There are two ways asphalt shingles are made. Either an organic-base or a fiber-glass base. The organic-base shingles are made from recycled woods fragments or waste paper. This kind of shingle is more durable and is extremely good. Also, it is better for the cold

Over time, people have taken the concept of a green roof a step further, adding garden plots with herbs or berries. More recently, larger commercial farms have begun to appear

Until the last decade or so, which has seen the introduction of incredibly strong and durable synthetic materials such as EPMD and PVC onto the market, most flat roofs were constructed using tar, gravel, and sheet metal, which while effective, have problems with durability and whose look is simply not associated with traditional residential buildings.

When you think of residential roofing, you probably conjure images of standard asphalt roofs, the most common variety in North America today. Yet, depending on where you live, this may not be true. Indeed, in addition to asphalt, there are a wide range of types of residential roofing including wooden shakes, metal, tile, slate, and fibreglass. Each homeowner will have an individualized preference, but also each type of roof has distinct advantages and disadvantages.

Passive and eco-friendly housing is becoming increasingly popular, and as more and more structures arise, learning provides scope for innovation, further cost saving and optimization. The rise of passive housing could have a possible impact on Global warming, an increasingly important topic, as housing contributes vastly to the cause: in 2009 buildings accounted for 43% of all the UK’s carbon emissions (gov.uk). Therefore, the UK Government aimed to reduce the UK’s greenhouse gas emission by at least 80% by 2050. To meet this target this could be achieved by moving to a more energy efficient, low-carbon economy. It would also help the UK become less reliant on imported fossil fuels and less exposed to higher energy prices in the future. Undoubtedly, some may have chosen to pursue a passive house as a way to protect the environment. Yet, at an individual level, the marginal benefit to society of extra investment is often considered as small compared to (in some cases) markedly increased costs. The important question, which will ultimately determine if passive housing will become a valid option for masses, is whether the additional spending is justified economically. The long term benefits of cost saving are visible (Passpedia (2015) Are Passive Houses cost-effective?), yet the marginal returns are decreasing. Therefore, Is the Passivhaus standard a cost effective way of achieving the UK CO2 emissions reduction target for new housing in practice?”. This research

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

A green roof is defined as a living roof at the top of a building which is either partly or totally covered with vegetation and a growing medium and underneath it is a strong and water resistant membrane. Some additional layers are sometimes included in it as well like root barrier along with a system of irrigation and drainage. Plants are grown on the top of the roofs and this helps in the replacement of vegetated footprints which were lost while constructing the

In this part, government attitude and policies are focused on, as well as advanced technologies are considered. Finally, this paper also turn to highlight the relevant field in China and what availability would suit for China, especially focus on what recommendations be suggested to local authorities in order to guide the whole society to aware the importance of green building and accelerate the development of this industry.
