1 2E9 Design and construction of a refugee shelter Sustainability and recycling plan Dr. Emma Siddall emma.siddall@tcd.ie

2 The sustainability and recycling plan together with the health and safety plan is 10% of your individual assessment. It needs to be roughly 2 pages long.

3 Overview What is sustainability? How does it relate to your refugee shelter? How to measure and improve sustainability. Recycling and waste considerations. What is a sustainability and recycling plan?

4 Sustainable development meets the needs of the present without compromising the ability of future generations to meet their own needs.

5 Both the economy and society operate in and are dependent on the natural world. In order for them to function we need to protect the environment.

6 How does sustainability relate to the design of your refugee shelter? The shelter needs to be economically, socially and environmentally sustainable.

7 Über Shelter

8 Economic sustainability Building refugee shelters in time of crisis is costly. Consider ways that this cost can be reduced. Reuse the shelters elsewhere Use less costly materials Reduce the amount of materials used Make shelters lighter and collapsible to reduce transport costs Use locally sourced materials to reduce transport costs

9 The Über Shelter is reusable. It is lightweight and collapsible thus reducing transport costs. It s easy to put together thus reducing manual labour costs.

10 Social sustainability When designing the shelter you need to consider: Health and safety Sense of place Environment and economy for other members of society Enhances well being of the population Help people to live together

11 The refugee and indigenous populations have to live with one another. This can cause problems.

12 The Über Shelter has amenities to improve sense of place. It is a two storey structure to reduce the geographical footprint.

14 Environmental sustainability The construction of buildings is a very environmentally damaging activity. Waste Generation Ireland ,000k tonnes / 4.24 M Pop. Industrial Muncipal Construction These impacts can be reduced through careful design of the shelter.

15 The main areas where environmental sustainability can be improved Careful selection and efficient use of construction..materials Reduction of waste and environmental impacts

16 Selection of construction materials Use locally sourced materials. Choose renewable or recyclable materials. Compare the environmental impact of different construction materials and choose the least damaging options.

17 Environmental impact of building materials A Life Cycle Analysis (LCA) is a suitable method to compare the environmental impacts of different building materials. LCA considers the impact on the environment at every stage of the manufacturing, use and disposal of a building material. This allows comparison of several materials and the selection of the least damaging option.

18 Life Cycle Analysis LCA considers the environmental inputs and outputs at every stage in the material s life cycle.

19 Life Cycle Analysis Building Material Cement Cement mortar Concrete LCA score (milipoints) You do not need to calculate the LCA values for the materials that you choose instead use published calculations in your report to justify why you chose the materials used. Values from Zabalza et al Life cycle assessment in building sector: Sate of the art and assessment of environmental impact for building materials.

21 The Über Shelter uses recycled aluminium which has a smaller environmental impact than virgin aluminium. It is fully reusable. It is light and collapsible so environmental impact from transport is reduced.

22 Design of the shelter Ensure that the structure is easy to dismantle..and can be reassembled elsewhere to be..used again. If the shelter lightweight and collapsible the..environmental impact from transport will..be reduced.

23 Recycling and waste considerations Construction and demolition waste amounts to 450 million tonnes per year in the EU alone. This level of waste production is economically, socially and environmentally unsustainable.

24 Solutions to the waste problem Reduce the amount of raw materials consumed Reuse the shelter or materials Recycle the waste

25 Reduce Reduce the use of non reusable or recyclable building materials. Ensure the efficient design and construction of the shelter to minimise unnecessary material use.

26 Reuse Design the structure so that it can be..disassembled and used elsewhere. Parts that can not be reused can be used for..another purpose.

27 Recycle

28 What happens if the waste goes to landfill? If the building material must go to landfill when you need to consider how long it takes to breakdown? Is it transported elsewhere, if so need to consider the environmental impact. What are the human health and environmental impacts?

29 Sustainability and recycling plan Discuss how your shelter design has considered each aspect of sustainability. Justify your choice of materials and design in terms of sustainability and recycling. Discuss how the waste has been minimised and what will happen to the waste that cannot be recycled.
