This is the final diary of our project. According to all of us this was one of the most challenging project that we have ever done. We had to do a lot of things and to coordinate our ideas to decide togheter. We used to do projects alone, just a few times we have done projects togheter, and according to all of us it was more easy to work alone because you have to coordinate only your mind and your own tasks, in this case we had to divide our roles and to coordinate our minds togheter and it was not easy to find a compromise when we were of different opinions. Good aspects of the project:
-As i said before this was a good project to learn how to work with a group and how to cordinate your minds with others;
-It was also useful to test our skills on the digital work;
-We learned a lot of things because this is a "personal project". We created a project about a topic that we didn't know so it was useful to learn something new about new types of roofs for cowsheds.
Bad aspects of the project: i have to say that i dont have a lot of "bad points" for this project beacuse it looked very difficult at the start but it was not so hard to work on it.
-i have just to say that for us it was not so easy to meet in one place
because we live far from each other.

Isaia: i am really satisfied of what i have done on this project. I think we have done a beautiful, simple but complete, project. I guess i worked well also if i found a little difficult on coordinating my ideas with the others because i used to do projects alone and how i want but this time i had to find some compromise and at the start it was not so easy for me.

Jacopo: in my opinion this was an hard project but i liked to do it also because i liked the group. The topic was cool but it wasn't easy to find some good documents on the internet so we spent a lot of time doing it.

Emanuele: as the others members of the group i found this project very interesting but also challenging. I liked the group because we work well togheter as our minds are not very different.

We started the project dividing our roles. As Isaia and Jacopo were in Ireland we did it calling each other. So it was not very easy to do it:
-Isaia: Material research and project diary;
-Jacopo: Material research and digital work;
-Emanuele: Material research and Infographic.

When we came back from Ireland we decided to make a project about the main advantages and disadvantages of green roofs. We also decided the final product. We decided to create an e-book with a programme called Sfogliami.
As it is easy to use and we like the final result we thought that it would be the best option for us.

We made a proof copy of the project at school and we decided to meet each other during the christmas holiday in order to do the main partof the digital work.
We spent a lot of time on choosing the best date for us and we finally decided to meet in the 29 of December.

# data[].attributes.body
We met each other at Isaia's home and we did the digital project using materials found on the internet. We searched a lot beacuse we didn't find it easily. We spent a lot of time to find the right documents and information and finally we found it.

# data[].attributes.body
We met each other at Isaia's home and we finished the project making timeline, infographic and the final diary. We used some cool websites for timeline and infographic and it was nice beacuse i learned how to use it.

We found some information about the main disadvantages of green roofs.

Green roofs, also known as living roofs, are rooftops covered with living vegetation planted in lightweight engineered soil over drainage material and a waterproof membrane. You can't use regular garden soil on green roofs because it often will compact and kill the plants. Although green roofs offer many benefits, such as providing an environment for wildlife, reducing stormwater runoff, and lowering a building's heating and cooling costs, there are a number of disadvantages to installing green roofs that may cause you to consider other roofing options.

The roof and load-bearing walls of many buildings may not be strong enough to support the added weight of a green roof. Thin, lightweight systems, known as "extensive" green roofs typically have a planting media measuring 2 to 6 inches deep, while heavier, thicker varieties are known as "intensive" green roofs and range in thickness from 6 to 18 inches or deeper. Extensive green roofs often weigh less than standard gravel and tar roofs. Intensive green roofs, however, may require additional structural support. Green roofs can only be installed on flat or gently sloping roofs. 25 degrees is generally the maximum allowed incline, although some green roof installers in Europe have grown turf on 45-degree inclines using innovative erosion control techniques.

Installation and Maintenance Costs

Installing a green roof can cost up to twice as much as installing a conventional roof. According to Green Roofs for Healthy Cities, an extensive green roof generally costs between $10 to $24 per square foot. Intensive green roofs, however, typically cost twice as much to install as extensive green roofs because of their thicker, more complex assembly. Maintenance for intensive green roofs can be labor-intensive and expensive. Extensive roofs require less watering and fertilizing, but as a bare minimum, they require yearly inspections to remove unwanted self-seeding plants. Homeowners can reduce costs by weeding, fertilizing and watering plants themselves instead of hiring a profession to maintain the green roof, and by growing their own plants from seeds rather than buying seedling plugs or mats.

Although most green roofs include a root barrier layer, the roots of plants sometimes penetrate the waterproof membrane, causing roof leaks that could result in structural damage to the building. A yearly inspection to remove problematic shrubs helps reduce the potential for developing leaks. Using a shallow growing medium usually prevents any plants from growing large enough to develop a strong, deep root system. Due to the complexity of a green roof assembly, finding the source of a leak and repairing it can be a challenging process. Green roof installers can perform flood tests immediately after the installation or repair of a roof to check for leaks. Some companies offer leak detectors that use electronic charges to trace the path of a leak to its source.

The thick growing medium of intensive green roofs can support the growth of a wide range of plants, including shrubs and small trees. The thinner, extensive green roofs, however, can typically only accommodate a small selection of drought-tolerant plants with shallow root systems. Sedums, lichens, mosses and low-growing grasses are common choices for extensive roofs. They look less lush, leafy, and, to some, less attractive than the plants grown in deeper soil. Less robust plants may also have trouble surviving the strong winds common on high rooftops.
