Week 7 Blog Post

For Week 7, the final proposal is due. All the data needed for the completion of the proposal were gathered as well as the designs of each systems (rainwater catchment, greywater recycling, and stormwater management systems). 

As a result of further research, the group found a design for the rainwater catchment systems that is compatible with the purpose of this project. Flexshade is a company that sells shading structures. One of their products is the Flexshade Lotus which looks like an inverted umbrella and is use for water harvesting. 
This image shows the Flexshade Lotus design and the materials used for each parts.
As what can be seen in the image, there is a drain located at the base of the rainwater catchment which is needed for collecting the water. 
For the stormwater management system, the design for the green roof was also determined. 
This images show what the base of the green roof will look like.
The drainage is one of two of the most important and unique aspects of the roof. All green and blue roofs have some sort of drainage, but the one being placed on the Dorrance H. Hamilton Building will slope towards gutters that will combine with the rainwater catchment system and lead to a cistern. The drainage is a plastic shield with small concrete enforced legs (left image) every few centimeters apart. Small holes allow, right image, water to fall onto the protective barrier of the concrete and enter a gutter.

Week 3 Blog Post              The group members list down the materials that are needed for the rainwater catchment, greywater recycling, and stormwater management systems and their costs. They also did further research of the rainwater catchment, greywater recycling, and storm water systems that might help them develop the designs of these systems.              The data needed for this project were also identified, such as the average precipitation in Philadelphia. Table 1 shows the rainfall depth for every month. This data will be used to know how much water can be collected from the systems and how much lesser the water usage from the main source is.

Week 2 Blog Post

Week 2                This week we focused on learning more about the site we would be focusing on. We discovered the exact building we’d be working o n at the Thomas Jefferson University campus would be the Dorrance H. Hamilton Building. The building is located in Center City, Philadelphia, the very urban part of the city. Because of this, little of the water will be reused for irrigation as there is none.                  It was also discovered that this specific facility currently operates as a teaching facility of the hospital. The breakdown of its water usage was determined. This data and other facts can be found at https://www.jefferson.edu/content/dam/tju/Hamilton/Hamilton_Building_Fact_Sheet.pdf “ www.igreenspot.com/watree-–-an-upside-down-umbrella-that-collects-rainwater/ ” Also, a possible location for the rainwater catchment system was discussed. This ...

Week 6 Blog Post

     Last week, students had no definite number of students or people that is present in the Dorrance Hamilton Building. The students conducted an interview with one of the guards that is assigned in the building. Mr. David, the guard in that building during the day that the students went to the place, stated that the capacity of the building is 2000 people, with 500 students (250 male and 250 female) and 26 employees (including the faculty and maintenance persons, 13 male and 13 female) in a daily basis. Using these information, students were able to make an estimated calculation of water usage in the sanitation part of the pie chart that is posted in the Project Overview .      Also, the group was able to put together some charts and tables that will be included in the final project report. Because there is no physical prototype for our project, we do not have a legitimate budget. However, we did calculate the approximate amount that it would cost to co...
